Our take on the iDatalink Maestro ADS-MRR Interface Module

iDatalink's Maestro ADS-MRR module, along with the correct interface harness for your vehicle, allows you to install a new car stereo in select late-model Ford, GM, Chrysler, Toyota, or Volkswagen vehicles while retaining your factory steering wheel audio controls and the use of your factory amplifier, if present.

iDatalink's Maestro RR module

iDatalink's Maestro RR module

iDatalink's Maestro ADS-MRR module, along with the correct interface harness for your vehicle, allows you to install a new car stereo in select late-model Ford, GM, Chrysler, Toyota, or Volkswagen vehicles while retaining your factory steering wheel audio controls and the use of your factory amplifier, if present.

Here's how it works

First, you connect the Maestro to your Windows-based computer (not compatible with Mac or Windows 10) using the included USB cable, visit, and follow the instructions. Once the unit has been "flashed," it's ready to go. Next, you'll either solder or crimp the vehicle-specific Maestro harness  (sold separately) to your new receiver's wiring, just like you would with any Crutchfield wiring harness or wiring adapter.

Important Note: You will also need an additional Maestro vehicle-specific wiring harness that connects your new receiver to the ADS-MRR module and your vehicle's wiring. We will automatically add this harness to your Cart at a discounted price when you purchase a new car stereo and this ADS-MRR module.

Retain steering wheel audio controls, too

The ADS-MRR module also allows you to use your factory steering wheel audio controls with your new receiver. Using the intuitive web programming interface, each factory button can be assigned a specific radio function. Better yet, you can also assign a secondary "press and hold" radio function to each factory button, effectively doubling what can be controlled.

Keeping your factory features with an iDatalink-ready car stereo

If you're buying a compatible Kenwood, JVC, Pioneer, or Alpine receiver, you'll enjoy the outstanding performance of your receiver, plus seamless touchscreen control over most of the factory features in select GM, Ford, Chrysler, or Volkswagen vehicles (see Details for specific functions and installation notes).

  • Ford: You'll keep your SYNC® system, including the factory Bluetooth, satellite radio (in select vehicles, see Details), steering wheel audio controls, and other great features.
  • GM: You'll retain the use of OnStar® system, along with your steering wheel audio controls, your factory amp, and safety warning chimes.
  • Chrysler: You'll retain the use of the Uconnect® system (including voice command), along with your steering wheel audio controls and factory amp.
  • Toyota: You'll retain your vehicle's A/V input, USB port, and backup camera.
  • Volkswagen: You'll retain your VW's Bluetooth, the factory digital amplifier and fader, plus VW's media device interface. Select Kenwood receivers allow you to display navigation info on your VW's multi-function screen.

Important Note: iDatalink Maestro RR is not compatible with a Mac.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

An absolute MUST for install in a Silverado. Keeps all the OE features and steering wheel controls. Keeps factory USB port operational.

Makes Install/integration a snap

An absolute MUST for install in a Silverado. Keeps all the OE features and steering wheel controls. Keeps factory USB port operational.

Pros: easy install, great sound, keeps all OE features in my truck

Cons: tight fit in the dash

Intregated great

T. R from Valdosta, GA on 10/9/2016

2011 Jeep Wrangler Unlimited
Crutchfield Customer Review (What's this?)

With a bit of head scratching I was able to figure out this installation. The kit comes with a quick start guide that sets you up with the correct installation guide and gives step by step instruction. Pairing this module with the vehicle specific harness(idatalink CH) and the Kenwood harness went smoothly and all the colors matched. The actual "plug-in" part of the installation got confusing since some of the connectors were not used and just remained hanging from the main harness and the kits comes with "extra" cables that are not labeled. My steering wheel controls did not work which had me looking at three manuals trying to track down the problem. I ended up finding a cable that was not mentioned in the installation instructions that actually clicked into the back of my Kenwood receiver and into the module. Instant fix for all the problem. I gave this product a 4 star because it does not clearly label all the items in the kit.

Pros: Retained factory features

Cons: Instructions not clear, headscratching involved

Great item to link factory to aftermarket

This product is amazing how it connects with my factory sync and links it to the radio giving me real time data on gauges and tire pressure. The only problem is when I have the radio Bluetooth and the sync connected it causes my radio to freeze up

Simplicity and support

Hands down the folks over at maestro have some of the best support and knowledge databases out there to help you install any setup. This unit fully integrated my car computer to my radio allowing diagnostic access, tire pressure check, and a fully customizable gauge layout. All while supporting any and every feature any modern car can provide.

Pros: Incredible instructions, simple direct connections with either male female connectors or direct solder. The support staff will handle any question quickly and provide you detailed assistance for any issues.

Cons: None, this product is a complete game changer when dealing with complicated in car infotainment systems

Full steering wheel control again!

David D. from Temecula, CA on 9/4/2016

2011 Toyota Tundra
Crutchfield Customer Review (What's this?)

Maestro was easy to install and gave me full steering wheel control again after losing some functions when Toyota installed a third party radio when I bought my Tundra. Programing took some time because I don't have a PC and my Mac will not work to program the module. Minor problem.

Pros: Programmable to probably work for almost any car. Small enough to tuck it behind your radio even with the ton of cables required to get my radio working.

Cons: Need a PC to program (minor) if you know someone that does have one.

Great Product

JackR from Houston, TX on 8/21/2016

2013 Jeep Wrangler Unlimited
Crutchfield Customer Review (What's this?)

Once I tried to not overthink it and actually spent 1 minute reading the instructions it was super simple to setup, configure and go. When I first started it up in the car with the radio, it noticed that I had a factory amp and asked if I was sure I didn't want to use it, as I had chosen not to in during the configuration. I acknowledged that I didn't want to use the factory amp and all was good.

Pros: Way easier than trying to wire everything yourself, plus the ability to retain the factory steering wheel controls make it a no brainer.

Cons: Requiring a Windows PC and a very old version of .Net seems kind of dated but everything worked without issue.

Crutchfield Customer Review (What's this?)

The instruction to "flash" the maestro are easy to follow on the website. Once you figure out that is what needs to be done you just enter your can information and the website takes care of everything else. Connect it to the idatalink and you are good to go.

Pros: easy to use once you get to the website and enter you car information, interacts with your car seamlessly

Cons: Figuring out how all the wires with the maestro and the idatalink work in unison is the hard part. lots of extra wires.

Works but the firmware listed to flash to unit may be incorrect

nbakings from Sacramento, CA on 7/26/2016

2010 Chevrolet Traverse
Crutchfield Customer Review (What's this?)

This unit DID finally do everything it was supposed to do, but it wasn't an easy process at least in my situation to get there. I expect it works great if your unit is one of specific units listed on the website (where you go to get the software to flash the Maestro RR) but my unit was a newer Blaupunkt, and all that was listed was generic Blaupunkt radio w/ or w/out Bluetooth. I flashed this for my Blaupunkt Cape Town 940 -- and it didn't work. Spent days reflashing, reconnecting, resetting speaking with the ADS team (who were great) until I researched that my newer Blaupunkt was actually a rebranded Chinese unit and used the Key 1 Key 2 type system for swc. I decided to choose one of the firmwares for these types of Chinese units, and it worked. All of the features it said it would retain it did retain for my system. So basically, installation would have been a breeze if the firmware had been correct one. Hopefully this will be addressed by the company.

Pros: Programmable unit for different radios so likely wont be obsolete in future with a new radio installation. Support by company is fantastic and they will keep working with you until it works.

Cons: Firmware lists on site are not completely up to date for brands in which the actual radio is not listed, so some trial and error to get correct firmware may be needed. The firmware flashing software requires Windows 7 to use at this time (Windows 7 is officially unsupported by Microsoft now, so I expect the company will have to fix this soon.)

B. Smith from Columbus, MS on 7/14/2016

2007 Chevrolet Suburban
Crutchfield Customer Review (What's this?)

Well first thing after opening it you have to get on their website to program it for your vehicle. That process is quick and easy. I thought it was cool that you could program your steering wheel controls how ever you wanted. The installation was easy. There was a couple of wires not used that come with it. Every thing works like it was supposed to on the first try.

Pros: It worked like it was supposed to. All radio functions and vehicle info worked.

Cons: Finding a good place to mount the box itself so that you would have enough of the harness left to connect to the head unit.

it works great, but instructions need help

Tim from Oklahoma City, OK on 7/12/2016

2010 Dodge Ram 1500
Crutchfield Customer Review (What's this?)

There is no doubt when the maestro is working the interface is great! But as with all things in aftermarket car the instructions are lacking. 1.) Please change the interface so that active-x is NOT required!!! Every browser HAS moved away from that technology. It does work in Windows 10, you just have to open internet explorer - not the Edge browser. 2.) Another major pain was the lack of instructions as to where to place to 2 interfaces from the radio to the maestro!! A.) 4 Pin connector goes to the black connection on the maestro!! B.) didn't even know that about the other 2 pin connector that connected to the Pioneer with an audio jack labeled WR.

Pros: gives lots of options once connected connectors attach very securely works with Windows 10 helpful knowing blinking red means no data connection

Cons: interface needed OLD internet explorer (not new Edge browser) sorely lacking instructions and diagrams if i had known where 4 pin plug went on the meastro wouldn't have needed blinking red light

I was worried about the steering wheel controls, but I got a lot more.

Robert from Los Angeles, CA on 7/5/2016

2011 Volkswagen GTI
Crutchfield Customer Review (What's this?)

The Maestro module was for my new Pioneer AVH-4200NEX. I was worried about the steering wheel controls, but I got a lot more than that with this module. The prep is tedious (programming settings and studying their installation instructions) but if you read everything and do like they say, the results are worth it. Besides keeping the steering wheel controls, I got: - backup and parking brake wires are part of the VW wiring harness, so I didn't have to take apart the interior just for the Head Unit (HU). - Vehicle info can be displayed on the HU (like engine load, RPM, MPG, etc) - I had a choice to use OEM or Pioneer bluetooth The BEST part - since the GTI has no accessory key position - is when I turn the key to OFF, the HU keeps playing, and the bluetooth keeps working. Until I pull out the key - that's when the HU turns OFF. With the OEM setup, the radio and bluetooth went off. You could make the radio play if you hit the ON/OFF button, but the bluetooth stayed off. The part about pulling out the key just makes so much sense for a VW.

Pros: Idata's web site was great for downloading whatever it was for setting up the module. Instructions detailed and clear. Adds features I never knew existed for a GTI.

Cons: Preparation, setup and wiring is tedious

Worked well, has limitations

Kevin from Flroida on 7/5/2016

2014 Ford F-150 XLT
Crutchfield Customer Review (What's this?)

I purchased this unit over the other units because I wanted to display above the radio to function. The product works well but I wish it had some other options available during programming. Programming the unit is easy enough, but you must use internet explorer and only internet explorer. I ended up programming the unit 5 times, but that was only to remove Sync and to change button configurations. I thought I wanted the buttons set a certain way only to find out I didn't like the way I had them. I ended up with the factory setup plus using the "ok" button as a mute. The secondary button option is a plus. Setup and test the buttons to make sure that you like the setup before finishing the radio install. Initially I wanted to retain Ford Sync, which this unit does. However, when I have it configured to use Sync I cannot use Pandora source on my headunit because it is paired to Sync. Well actually, I can play Pandora and such through Ford Sync, but you control it from the phone. I liked it paied to the radio better since I can see the Pandora song information and can control Pandora from the headunit. I decided to do away with Sync since my radio does all the functions that Sync does but better. I found out with this setup I cannot use the factory microphone, I had to install the one that came with the radio.

Pros: Easy setup, secondary steering wheel button functionality a plus. With the right wiring harness, I didn't have to cut any of my factory wiring. I did have to call tech support, one guy seemed very helpful the other one not so much.

Cons: Must purchase a separate vehicle harness. A lot of excess wire. The instructions definitely could be better. You have to download the instruction and diagram from the internet. The diagram was enough to wire the unit, but there was not a decent instruction manual to cover the programming process, though it is easy. There is nothing that discusses the options you can select during programming. Had to call tech support to find out if I do not use Ford Sync, I could not use the factory microphone.

Include instructions with the product! Even the online instructions are less than stellar. Lots of guesswork goes into the installation process.

Anthony from Corpus Christi, TX on 6/23/2016

2012 Ford F-150 FX2
Crutchfield Customer Review (What's this?)

Great harness, however, you must have a Windows PC to program it. There were issues programming, but I figured it out. Read the installation instructions carefully, and if you follow them, it's a snap! No issues at all once I installed it, takes about 30 mins.

Pros: Once you get it programmed, it makes everything work great!

Cons: Programming can be a pain, and Crutchfield can't help you. You have to deal with iDataLink, and that can be difficult if you have a job, as their business hours are very inconvenient for the working public.

Worked perfect after some figuring out

DC from Cedar Rapids, IA on 6/13/2016

2010 Ford F-150 Lariat
Crutchfield Customer Review (What's this?)

This unit worked well and was easy to program ONCE....I figured things out. NOTE: this requires activeX to flash the unit or program for your vehicle. You do it via the web interface. For me, I have Chrome, Firefox and Microsoft Edge none of which support ActiveX. So, I had to download an old version of Microsoft IE to run ActiveX. Other than that, things went well and install was fine. There is probably an easier way but, I installed on a Sunday and their tech support is only available M-F. I didn't call Crutchfield maybe they would have a better answer? As awesome as the Crutchfield team is, I'm sure they would have.

Pros: It does what it's supposed to do, programmable options,

Cons: Had to download older version of IE to run ActiveX, directions are not extremely clear and kind of basic.

Maestro needs some needs some directions

Timm from FL on 6/12/2016

2008 Chevrolet Suburban
Crutchfield Customer Review (What's this?)

Where to start... I bought the components(Pionner 3800BHS, Maestro RR, Idatalink HRRGM5, Sirus/XM-SXV300) recommended by Crutchfield that I needed to keep my SWC and OnStar but all I got was SWC. Installation requires an internet connected PC. That was fine until I had to take the unit out to re-flash about 6 or 7 times to no avail. I'm wondering how many times you can actually plug and un-plug the cables before having an issue. Thankfully the installer did nor close up all the panels so we could work with the Maestro unit as we found the issue checking the install. OnStar can faintly be heard and does not hear me. They have had me flash the unit more times than I want to admit and have had tried 3 or more different firmware versions. Crutchfield support has been really good I wish I could say the same for the Maestro product. Have not heard anything in 9 days now. Beyond my return date so I'm now stuck with a piece of junk.

Pros: Small, compact, ok price

Cons: -Must connect to PC and flash before use. -Does not retain ONSTAR. Do not take them at their word. Test everything and if they can't make it work within a week. return it! -Does not retain onboard Sirius/XM(requires a new Sirius/XM radio box).

Pros: Not to hard to install did not connect with some features May have been caused by Fords famous running changes. Crutchfields phone people were great in making be happy with whole deal.

Amazing product this was my first time using this product after many previous double din navigation and dvd receiver installs in the past. Made the wiring plug and play. The programming was easy and the added steering wheel functions are super nice. I will certainly use this whenever possible in the future.

Pros: Easy to use. Simplified wiring to plug and play, Maintained steering wheel controls, all factory speakers and factory subwoofer. Ability to choose to maintain power during cranking (nice for the cold mornings when the glow plugs warm up for 20 seconds) Integrated flawlessly with Kenwood Head Unit

Cons: None for my application

This is a must with most later model vehicles. It allowed me to retain steering wheel controls, Bluetooth phone and aftermarket backup camera. I also really like the fact that it comes with a small external speaker that I elected not to install so now I don't have to listen to the annoying door chime when my door is open, and no more annoying blinkers clicking. You will lose on-star audio from what I'm told but I would never have used it anyways.

Pioneer AVH 4200 NEX in 2016 Toyota Rav4

mehoves from Sulphur, LA on 5/22/2016

2016 Toyota RAV4
Crutchfield Customer Review (What's this?)

You must use the T02 harness with this in a 2016 Toyota Rav4, not the T01 harness. It also says the square plug is not needed, but it is needed for the factory usb in the front. I plugged the usb end of the plug into my Android Auto USB (USB2) of the Pioneer 4200 NEX and it worked. Everything is retained from factory except the factory Bluetooth mic which you would think it would be possible. This includes the rear camera, steering wheel controls, usb, aux, and it reads the vehicle computer very well. The factory settings controlled through the factory head unit (for door lock and light options) are retained and carried over into the settings. It also shows my tire pressure where as it did not do this factory. I have the LE model which does not have the read out but apparently the sensors are still there. It shows RPM, MPH, Engine Load, Coolant Temp, Fuel/Air Ratio, to just name a few on the dash unit.

Pros: Does everything and more, too many pro's to list.

Cons: Nothing

Product functioned great until it started smoking

Maestro RR 2013 Tahoe

Crutchfield Customer Review (What's this?)

I'm currently still in the install process. I had a very hard time linking this up to a pioneer 4100 NEX, I have spent countless hours on the phone with Crutchfield trying to solve issue. I currently am not able to retain my factory Rear system audio (RSA) headphone jacks for the kid. Idatalink currently will not power on a Kenwood 9702s and I've reflashed the module countless times. Has not been as rock solid as I've read. I'm definelty worried I'll be driving and lose all radio functions. Wiring diagrams are ver generic from Idatalink and did not match exactly the module I had. Crutchfield has been a lot of help trying to resolve these issues and Idatalink has not been much help.



Needs some work / great idea

Expedition Driver from Denver on 4/1/2016

2010 Ford Expedition
Crutchfield Customer Review (What's this?)

It's a great idea, but make sure you go to the iDatalink website and use the simulator to make sure it'll meet your needs. Mine will not use the Voice, OK, or Phone buttons on the steering wheel unless you keep the Ford OEM Sync. Sync is what was my reason for replacing the entire system. It's a 2010 Expedition with 2007 Ford software trying to interface with an iPhone 6 Plus running an iOS that came out last week (April 2016) No wonder the sync no longer speaks to my iPhones. So, iDatalink, you need to be a replacement for the Ford Sync My Ride and work on your own with all the buttons and functions. Not being able to go "next preset" is annoying at best. I was told I'd have to configure this in the Kenwood, but that option is not there. Connecting to the Ford system reproduces the problem I had to begin with

Pros: Great idea... I bet it's awesome for some

Cons: Not enough programmable key options in the pull down menu for each button function.

Extremely finicky hardware

Zachary from santee, CA on 3/28/2016

2015 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

I am not impressed with the Maestro RR. I bought a Pioneer AVIC-8100NEX that said "optimized for the Maestro RR." Trying to get everything working in my truck with this thing was a heck of a time. I ended up having to call Maestro's tech support because I couldn't get my truck to start after I had everything hooked up. Tech support literally had me unplug everything and plug it all in one piece at a time. The final formula was the exact same thing I did in the first place. After I hung up with tech support, I mounted the radio and everything else in the dash kit then reassembled the dash. My truck wouldn't start again. For some reason, my truck absolutely refuses to start unless I have the original WiFi module installed along with the Maestro. The only things that work fairly flawlessly are the blinkers and door chimes. One very annoying issue is the accessory kill option, I'm supposed to be able to start my truck without the radio turning off. My 8100NEX takes a long time to turn on and even longer every time I start the truck. I don't know if my truck was/is the issue, but next time I'll stick to the Metra kit.

Pros: Can potentially give a HUD of engine diagnostics Can be controlled through the head unit Keeps factory sounds and warnings The included chime speaker has impressively high volume

Cons: Was difficult to install and get running The blinker volume sometimes jumps to max volume Radio turns off when I start my truck Maestro (not Crutchfield) tech support was not knowledgeable towards my vehicle at all. Their only suggestions were unplug everything and start over. Doesn't show anything when I adjust my climate controls It has an additional plethora of wires that aren't conducive to working in a tight space

Works as promised

Crutchfield Customer Review (What's this?)

This worked great except for one button on the steering wheel. I programmed the "volume down" button to reduce volume but it brings the preset channels down. I am currently working with Maestro on a software fix. Other than that it worked great. The online instruction could be improved. You have to select a steering wheel type. One with no telephone buttons or one with audio only buttons or one with no buttons. You select a picture in the app that matches your steering wheel. The images look exactly alike for one with telephone buttons and audio buttons or the one with audio buttons only. That can be confusing.

Pros: Allows you to retain factory features while greatly improving the radio.

Cons: one software bug.

Complex, but worth it.

It does what it says it does. I was lucky to be working in a dash that had a lot of space available.....normal sized vehicles may pose a challenge to find a place for it and the wires. The instructions didn't quite match the unit....some of the wiring didn't quite match up and directions are a little vague on what the specific wires do. There were a number of calls to tech support and pulling the unit a couple of times to get everything working right. Tech support is only open during "normal" hours, which of course, are not the hours most self-installers are working on it, so a few days drifted by. But this is six months later and it continues to work flawlessly.

Pros: Makes keeping your steering wheel controls possible. Use means very minimal wire splicing.

Cons: Takes up some space and may not be testable until things are fairly put back together. Changes mean pulling it all out again.

Crutchfield Customer Review (What's this?)

It's not what I expected.

Pros: Some of my factory stuff works.

Cons: So when I hold down volume down button on my steering console. It goes to mute. I dislike this greatly. The Hang up button on the steering wheel is obsolete. I am so unsatifised with this. Also The equipment is only PC compatible. I own a MAC. I didn't find this out until I relieved it. Who looks to see if a piece of equipment for their truck is PC or MAC compatible. It was a pain to get it setup.

Break out the spaghetti! Between this and the Maestro K150, wow! After looking at the wiring, though, it wasn't so bad. Not all wires will be used. This has a cable that connects directly to my Kenwood for data communication.

Pros: Allows seemless integration. Best system I've used to date.

Cons: Having to find a PC to use to flash the module. I thought we had moved on from those dark days.

Product seems to be working fine once installed. The downloading procedure off of your computer is very hard. I contacted tech support and was told I had the wrong web browser (and I have three). Ended up taking it to another retailer to have them download the drivers so it could communicate with my vehicle. Allow extra time for downloading the drivers to the product. Other than that it works fine and is worth the time to use.

The iDatalink Maestro works perfectly with my 2012 Expedition and Alpine X008U to retain Sync for and free calling and internal gauges display. Complicated wiring harness, but definitely worth it to maintain full factory functionality.

Pros: Perfect for maintaining factory system integration.

Cons: Quirky to program, requires Internet Explorer and Windows to program, with some security features turned off. I had to dive into the iDatalink forums to find the solution to get it programmed.

Rocco from Utah on 12/29/2015

2013 Ford F-150 XLT
Crutchfield Customer Review (What's this?)

I installed this on a 2013 F150 after replacing the entire factory system. I have retained all factory functionality, including SYNC (for better or worse), the steering wheel controls work great (no delays), and the vehicle diagnostics are pretty cool too. Installation was not nearly as bad as I thought it might be, with zero wire-tapping and just a few crimp connects between the aftermarket receiver's main harness and this unit. Everything else was direct harness-to-harness connections, including the OBD-II connection (which will have to be unplugged for diagnostics by a repair shop or emissions inspection.

Pros: Maintained 100% of my original functionality plus added a few features I didn't have before.

Cons: A huge spaghetti bowl of wiring. You can expect to spend a fair amount of time just staring at the wiring diagram and actual wires before it finally clicks in your head and you understand what to do with all of it.

Great for Steering Wheel Buttons

EricJK from Battle Ground, WA on 12/19/2015

2007 Dodge Caliber
Crutchfield Customer Review (What's this?)

Excellent support of steering wheel switches in Dodge Caliber. However, integration with other devices isn't as good. Fader control may be lost with factory amplifiers.

Pros: Allows customization of the steering wheel buttons to allow most common functions to be handled without removing your hands from the steering wheel. For example, Mute can be set up as a press-and-hold of down volume, unlike factory radio which requires reaching over to the head unit.

Cons: Doesn't support all factory digital amplifier features. Per Crutchfield tech support, only certain head units will support the digital output needed to keep the fader control.

Gotta say, I was quite impressed with this little guy. Programming and updates worked fine first time. Steering wheel controls are customizable and work as expected.

Pros: Works as advertised, made the install very easy.

Cons: The programming and updating via the website was a little tricky to get working due to browser restrictions and web based content management. Most web based applications are like that, but this one couldn't use chrome or MS Edge (default in windows 10). I had to open up an older version of Internet Explorer to get it work.

Will not work 100% with Pioneer AVIC-4100NEX

Anonymous from California on 9/19/2015

2014 Jeep Wrangler Unlimited
Crutchfield Customer Review (What's this?)

This review is based on my experience with the Maestro iDatalink coupled to a Pioneer AVIC-4100NEX receiver in a 2014 Jeep Wrangler with the stock Alpine Radio System. I changed out the head unit for the Pioneer AVIC-4100NEX. I have used Pioneer for decades. Always liked the interface and performance. Tried others but came back to Pioneer. I coupled it with the Maestro iDatalink to retain steering wheel and voice controls. It works fine except the fader will not stay set. Once the car is turned off and back on the fader setting reverts back to 0 (or near zero, it's not always zero). Pioneer blames iDatalink and says there are no updates for the 4100NEX. Crutchfield says it's an issue with Pioneer. Looking on the net, seems that the Metra ASWC-1 works with the Pioneer although that unit requires some wire splicing. Crutchfield sells it. Don't know if I can get my money back on the iDatalink, it's been 6 months since purchase. But I will try the Metra ASWC-1 in hopes that the fader setting will stay set.

Crutchfield Customer Review (What's this?)

Great little device to retain factory features and wiring. I used this gizmo to retain the steering wheel controls and use of the factory Infinity amplifier and speakers in my '11 Wrangler when I installed a Pioneer head unit. For my application a couple of the wires were Very difficult to access, but they are unique to my vehicle and I may have approached them from the wrong panel. The iDatalink Maestro must be programmed before you use it and you will need to do some soldering on the harness. Once installed it worked perfectly as advertised.

Pros: Does what it says. It let me keep using my steering wheel controls and factory installed amplifier after installing my Pioneer head unit.

Cons: It takes some work to install, but it is easy work if you can solder wires and apply some heat shrink.

Part of the recommended install kit for the JVC KW-V11 I purchased. The instructions provided for the Maestro from their website led to a support call with Crutchfield. The support tech was able to diagnose and resolve the issue quickly.

TedS from New York on 9/8/2015

2008 Lincoln MKX
Crutchfield Customer Review (What's this?)

Hookup was easy with this, the required ford harness, and a pioneer unit. Wiring diagram was pretty simple to follow, and once the harnesses were all wired together it was pretty much plug-in ready, then a few simple steps when first powered up to complete the programming setup and it was done. All the steering wheel controls work great, and are even customizable. I can return to using Sync if I want to re-flash the module (am currently not using Sync) and factory amp is still used for my amp with this unit.

Pros: Everything works great, is customizable, and can be re-flashed if you want to change which factory features to retain later.

Cons: Instructions seem a little outdated, as it showed splicing into a couple of wires for the OBD-II connection but the harness actually came with an OBD-II plug on those wires, so it just had to be plugged into the OBD-II plug in the vehicle.

Scott from Ohio on 7/27/2015

Crutchfield Customer Review (What's this?)

Lets me keep my Sync - Steering Wheel controls etc.. now with their newer version (and new harness version) dont even have to cut into any wires for the OBDII link or the Sync module link. Its completely plug and play after you do the initial software install from your PC. Only thing Ive seen that I would call a negative is it sometimes gets a little buggy on the stereo controls when you try and make configuration changes to the OBDII settings - have to reboot radio as it will lock up from time to time. but not sure if that is this module OR the Stereo.. The other issue would be their directions for my F150 and stereo combination were a little off.. as their new harness has you connect the speaker leads (which now have RCA jacks on them) to the amplifier output jacks -- well of course with no amplifier feeding those into the factory harness... you get only a whisper of sound..easily remedied by cutting off the RCA jacks and connecting to the stereo high power output leads. Other quirk I noticed as I have two of these modules on two vehicles -- on my F150 it doesnt allow you to pull trouble codes from the ECU or any data for the gauges screens other than RPM.. same module / same stereo on my 2013 Mustang - will read trouble codes and clear them if I want -- gives me almost 35 different engine conditions I can monitor on the gauges screen.. not sure why they would be different .. but they are - All in all though makes an aftermarket stereo install VERY simple.

Pros: Keeps Sync, Steering Wheel Controls, Sync Bluetooth with nothing but snapping on the correct harness plugs to the module. Also allows you to see the TPMS data, Battery Voltage, and in some cases trouble codes -AND definitions for them - and reset them too.. If you can follow simple directions VERY quick and easy to install.

Cons: sometimes communication with the ODBII gets a little quirky. If module cant be reset from stereo when it locks up you have to take your dash apart again to reset it manually. (Both of those instances only happened 1 time in 18 months) - Froze up - unable to reset or control from stereo - had to pull it out and do manual reset with button on housing.

I've used harnesses before but I didn't like this one. My chimes were retained, but I don't like that onstar and oem bluetooth comes through the chime speaker. There's also a wire for the parking brake to hook to your stereo so you won't have to tap your car wire, but that didn't work. I called idatalink, they said the car sends data through that tells the radio its in park and nothing I can do about the chime speaker situation thats how it works. Maybe it's just my car? You have to flash the module, and everything else is easy if you follow directions after that.

Pros: My stereo works and I have chimes at least

Cons: Parking brake wire didn't work. Bluetooth and onstar comes through chime in dash. I wish I returned this and stuck with pac or metra

I was able to find all of the wiring diagrams online and printed the pages to a file as recommended, then reviewed the instructions on my phone while crimping all of the wires in the harness. If you are familiar with crimp connects and working with thin gauge wire, then this installation will not be a challenge. Be sure to flash the device prior to installation.

2007 Jeep Grand Cherokee
Crutchfield Customer Review (What's this?)

Chose the IDatalink Maestro because it promised the most when paired with my Pioneer AVIC-7000NEX, I was wrong. Per IDatalink's own latest manual for my Grand Cherokee SRT8 "retains steering wheel controls, Uconnect, Uconnect Bluetooth, and more!". More? Do tell because all I got was the steering wheel controls, nothing else. The install instructions were outdated "latest from their website" and I later found I didn't need to hook up one supplied cable or splice in the OBD2 connections.. Two stars for keeping steering wheel controls and factory amp (which I don't need). Also being that it was their harness they could've supplied backup cam and gps adapters. Please note Crutchfield isn't responsible for these issues and they did throw in the IDatalink and harness at quite a discount with the head unit.

Pros: Keeps steering wheel controls and factory amp.

Cons: Overpriced, Doesn't deliver as promised, bulky with the harnesses, outdated installation instructions.

Crutchfield Customer Review (What's this?)

This product is amazing, and it's the primary reason I chose to install an aftermarket radio into my brand new F250. All of my Sync features and steering wheel controls were retained, with plenty of bonuses provided by the Idatalink Sync combination. The only drawback was the sheer volume of wires that the harness marriage produces. I personally couldn't fit it into my dash, and had to have my set up professionally installed. I flashed the module and wired the harnesses together, but couldn't fit the radio and harnesses into the radio cavity. I can't say if that's a problem for other vehicles, but it was for mine. It took someone with experience to run that stuff through my dash.

Pros: It retains all factory Sync features w/ bonus features.

Cons: Volume of wires from the harnesses.

Not the easiest thing to install. First of all, required Windows 7 running Internet Explorer. I have never used a Windows computer before (sorry, lifelong Mac person). Finally borrowed a computer and my car was not listed in the options. Called to iDatalink and they said "just pretend you have last year's model and that should probably work." Really, are you kidding me? Finally got it flashed and installed but took more effort than it should have. However, I do like that not only did I keep my steering wheel controls, I got to program them to do exactly what I wanted them to do.

Pros: Custom steering wheel buttons

Cons: Requires an outdated Windows system to program

Pros: Small profile for fitting behind the dash better, with the right kit I had everything and more for wires

Cons: The reset button can be easily pressed depending on how its mounted, the instructions could be easier to follow, and it would be nice if the company offered the programing app for mac computers.

So far my experience with this device has not been the greatest. I bought this along with the gm5+ to work with my ahv-x4700bs. i have an 078 silverado ext cab ltz w/ bose system. So far after flashing the firmware on the head unit and downloading the programmer for the unit and putting the right profile on it, half the time the chimes dont work, not just the door open chime or open with key in chime. it also effects my back up assist chimes and blinkers. The steering wheel controls work as they should half the time, the other half they do the opposite of what they should. Sometimes when i play music via bluetooth i can no longer hear phone audio through my speakers afterwards, im not sure if that is part of the rr problem or the head unit though. I also have an android phone with mirrorlink abilities and half the time it doesnt work right either.

Pros: easy to update. update ability should mean better functionality

Cons: entirely way to bulky with the box and the extra speaker they require to use and all the cables.

The set up states that you need to flash the module with a computer running windows 7 or earlier.

Lots of wires to work through. However, all wires are color coded and if you take your time and follow the installation instructions carefully all steering wheel functionality remains intact as it was from the factory. I had to call iDatalink's customer support concerning the plugin that has to be installed before you flash your unit. The technician was very helpful and was able to resolve my plugin installation problem within 5 minutes.

Pros: You are able to retain your steering wheel functionality with an aftermarket stereo.

Cons: Live customer support is available on weekdays only. No live customer support on the weekends.

Pioneer AVH4000NEX to 2012 F-150 Installq

Zach from Anchorage, AK on 4/1/2015

2012 Ford F-150 Platinum
Crutchfield Customer Review (What's this?)

As other reviewers have pointed out, the iDatalink is a decent product in concept, not necessarily in practice. Note that this review encompasses both units I've had to tear my truck apart to install. Basically, interfacing the phone functionality between the Pioneer and factory Sync properly is a mystery to tech support at Crutchfield, Pioneer, and iDatalink. Once the install instructions are followed (and even reflashing the unit two to three times) the radio is incapable of answering calls from the steering wheel and will display "unknown" to any contacts associated with Sync phone commands: (call John Smith; "calling John Smith" - radio display shows "unknown" and all call commands have to be initiated from radio screen. God bless Crutchfield for trying, but their tech support is ill-prepared to deal with all the nuances of all the products they sell. Calling Pioneer or iDatalink results in a blame game as to whose interface is causing the problem and neither offers meaningful support. Good thing the radio is smarter than all of us and rebooted itself at a stoplight yesterday and NOW my phone works like a charm! Apparently this last step should be added to the instruction manual? The only remaining issue is that trying to skip a song on my iPod/iPhone from my steering wheel results in it skipping through the song and not over it. Irritating, but at this point - I'll take it!

Pros: Great to be able to ditch the factory six disc for something that can keep up with my smartphone but keep factory steering wheel and bluetooth.

Cons: Install instructions and tech support are crap. Also, who uses Windows/Internet Explorer anymore? Wake up and service the 50% of the population on Mac OS. If you're a tech product you shouldn't have to use stone age technology to program it.

Mostly works

Crutchfield Customer Review (What's this?)

It does what it says it will do for the most part. instructions i received were incorrect though. but a quick call to Crutchfield and they confirmed i did indeed need to cut the RCA's off the speaker wires since i was not going to an amp with the doors even though the instruction sheet said that there were separate wires for that function. SYNC pretty much works always. It is a little slower starting and responding than before and has developed an issue staying paired with my phone since adding the idatalink. but i haven't been annoyed enough with it to do anything about it. I could have sworn the compatibility matrix said my factory sat radio would be retained. it was not though. not that big of a deal, but something for future buyers to double check if they are interested in keeping sat radio,.

Pros: able to program steering wheel buttons for long hold integrates factory features with less hassle than other products i have dealt with ODB II connection lets you get data about your car on the fly and custom gauges with i really like

Cons: has somehow created a weird bluetooth issue sync runs a little slow

iDatalink Maestro Rr for Chrsler

gatorguy from Kokomo, Indiana on 3/28/2015

2007 Dodge Ram 1500
Crutchfield Customer Review (What's this?)

Apparently this is a necessary piece of equipment to use when installing an aftermarket radio. Especially when my 07 RAM 1500 has an Infinity 7 speaker sound system with its own Infinity amp. After stumbling thru the online instructions and a call or two to Crutchfield tech support, I completed the installation. It works fairly well as far as steering wheel controls, but the MAESTRO will not let me fade the music from front to rear. Called again to Crutchfield tech support and was informed that it only received two channel input. Kinda wierd, but not terrible. All 7 speakers still get powered by the Infinity amp, but by only 2 channel feed, not 4. Still sounds really good in truck because I added an amplified subwoofer and there is no need to fade the audio. My subwoofer uses the sub signal from the stereo, so the MAESTRO doesn't effect it. Overall a good unit. Couldn't use factory amp without it. If it allowed me to fade the audio then I would have given it 5 stars.

Pros: Works as described

Cons: Doesn't fade audio front to rear.

Crutchfield Customer Review (What's this?)

Should have done more research. What advisors say from idatalink vs Crutchfield becomes conflicting. Diagram says one thing, written instructions says different, Crutchfiled advisors say another-which one is right!!? Pretty much useless for Jeep/Chrysler interface.

Pros: Added new features to steering wheel controls-that's it

Cons: Lost fade capabilities with stock amp-all the interface components do this (Crutchfield advisors). Wiring was conflicting and confusing, not with radio harness but with yellow/red/brown wiring to OBD port. Had to flash it twice and NO APPLE interface-only Microsoft.

Crutchfield Customer Review (What's this?)

Works great, but you have to connect it to computer and internet for programming prior to installation. Not real complicated, but it is a bit daunting.

Pros: The fact that someone even makes a device that makes changing to an aftermarket radio possible while maintaining steering wheel controls is impressive.

Cons: Have to program it yourself via usb connection to internet.

2010 Ford Mustang
Crutchfield Customer Review (What's this?)

First took about 2 hours and 2 calls to IDatalink customer service to get the box to flash. Then my installer could not get the Maestro to interface with my Mustang's SYNC system (tried every single wire), another couple hours wasted. Fortunately my installer had an extra steering wheel control unit or I would have wasted the entire day, and I get more features from my new head unit (Pioneer NEX8000) than I get from SYNCH anyways. Anyways, had to return it, 1 star for the Maestro, but as always Crutchfield service was great -- they get 5 stars.

Pros: None

Cons: Extreme difficulty in loading software/flashing from iDatalink online site. Professional installer couldn't get box to interface with SYNCH as advertised.

A great product

Darin from Denver, CO on 3/9/2015

2011 Ford Focus
Crutchfield Customer Review (What's this?)

Allowed for me to keep the steering wheel controls and Ford Sync in a 2011 Ford Focus. When adding it to the Crutchfield Cart, they claim it will retain Satellite Radio, when in fact it does not. Not a big deal for me, as I do not subscribe to sat radio, but it is misleading. I like the simplicity of programming the individual steering wheel keys, and ability to choose which OEM features to keep. I opted to not use the OEM bluetooth, and was able to switch the steering wheel buttons to integrate with the aftermarket radio bluetooth. Slight hiccup when installing, as it requires spicing in to the OEM and Sync wiring. OEM was no issue, but the wire colors going to Sync were difficult to tell apart. The grays and blues were very similar. Would have preferred a pin number on the Sync wiring harness connector. That would have saved some time spent pining over the colors. Called Crutchfield tech support to see if they had the pin numbers, but they were no help. They told me it should be obvious by the color. I would have provided the pin number here, but as tech support suggests, it should be obvious, so I won't bother.

Pros: Easy to customize.

Cons: Misleading information on Crutchfield website about retaining Satellite Radio with 2011 Ford Focus. Not a fault with product, so did not affect my rating. The product received did not match the connectors in the instructions, but it was easy enough to figure out. Maestro should upgrade the documents to match the product.

Crutchfield response on March 16, 2015 Thanks for taking the time to share your feedback with us. We're reviewing the logic that makes our site say that the adapter retains satellite radio. We'll adjust our database so that the correct information is shown. Sorry you weren't able to get that pinout information. We've passed along your feedback to the Tech Support team for review.

This product is great along with the additional wire harness and It was recommended by customer service. Once received, I thought oh boy because of all the wires. But after an easy "flash" on my computer, it was pretty much idiot proof after that. The product controls my SWC just as designed on my 2008 F350 with a Jensen V7020 head unit.

Pros: Easy setup and install Easy to follow directions and wiring schematic.

Cons: Really can't think of any

Easy hook up

TomC from Chesapeake VA on 2/24/2015

2008 Ford F-250 Super Duty
Crutchfield Customer Review (What's this?)

Easy to hook up and use. Wired right into the radio and truck with only a little confusion with the wiring. The Stock AUX did not work with this system and had to be wired into the Radio's second Audio input. The directions were a little vague regarding this and what was required and not required. After a few phone calls it was worked out. Now, AUX is wired as an extra plug and the Audio is connected to my stock AUX. It seems to be a bypass for proper set up. Now I don't have the video in hooked up that goes with the audio in so I don't know if that causes issues if a second video player is hooked up and needs both the vid/audio to play on the unit.

Pros: Easy to use and works great with the stock set up minus the AUX

Cons: System is NOT compatible with MAC for programing. A windows system is a must. Wiring diagram doesn't explain clearly how the AUX system is set up.

Unit Is A Total FAIL

DaveK from Utah on 2/8/2015

2013 Volkswagen CC
Crutchfield Customer Review (What's this?)

What I did not like and was VERY disappointing in was the Maestro RR interface. This was supposed to give me all the original functionality of my in car unit, plus all kinds of looks into the gauges and stuff like temp and oil pressure. I also thought it was supposed to simplify the hook up of the car stereo.Don't believe ANY of that! First off, the instructions DID NOT match the unit I have. Connectors were different (changed) on the unit shipped from what the instructions show. No explanation on how to hook up the new wires. Second, I still had to solder a LOT of wires. It may have simplified SOMEWHAT the soldering, but there is still a LOT more to do. I thought this was going to be plug and play. It is NOT. I contacted iDatalink and got NO RESPONSE. Crutchfield responded quickly, but ended up saying for me to get the mic function that is built into my car, I would have to hard wire in a whole new mic... All in all this unit was a lot of broken promises and expectations...

Pros: None

Cons: It does NOT work as advertised, and makes more promises than it can deliver.

It Works But Not 100%

Cory from Bakersfield, CS on 2/2/2015

2007 Chevrolet Suburban
Crutchfield Customer Review (What's this?)

This setup worked with my existing factory setup but needless to say if I didn't have a friend who is well versed in stereo install I would of been lost. It works though but not until after much troubleshooting with my Pioneer head unit. What frustrates me the most is that after flashing the module with my exact head unit, the module didn't work. Only after a suggestion from Crutchfield to flash the module with a generic Pioneer firmware did the box work. Why allow you to choose your specific unit if it won't work? Strange. Still missing the turn signal sound from my vehicle.

Pros: Combines well with factory system

Cons: The flashing if your exact model stereo (Pioneer) isn't always right

Very Necessary Device

Rob from Michigan on 2/1/2015

Crutchfield Customer Review (What's this?)

This product is a must for anyone wanting to retain the original vehicle features (such as OnStar, warning chimes, steering wheel controls, etc) with their aftermarket stereo receiver. It is actually pretty easy to install and enables you to print very detailed installation instruction (for your vehicle) from the Maestro website once you complete the required online setup (called flashing). However, don't miss the fine print. This unit can only be setup to work with you specific vehicle, via the use of a PC with internet access. You will need administrative rights to the PC you use for this so you can download the required Active-X file. No Mac computer allowed for this process.

Pros: Works great! Easy to install with detailed wiring diagrams.

Cons: Can only be setup with a PC! No Mac computer will work for the required online initial setup!

Park Sense and Uconnect not supported 2005 Jeep Grand Cherokee

Andregg from Virginia on 1/17/2015

Steering wheel controls are the only retained item for 2005 Grand Cherokee limited. Uconnect isn't a big deal but the parking sensors no longer work when the maestro is in the system. The product is sold with the belief you retain all features that were factory until you install it and then begin the task of troubleshooting only to find that for a given software download and your make/model/year that only some features work.....Painful

Pros: Fairly simple wiring harness, except OBD II connections

Cons: Lost 2 out of 3 factory features

Does not retain UConnect on 06 Jeep Grand Cherokee

BobbyH from Houston, TX on 1/6/2015

Firstly, both Crutchfield and iDatalink have been extremely friendly and helpful throughout all my questioning and research. However, it stops there... I've spend at least the past 3-4 days troubleshooting my so called "retained" OEM features just to find out that iDatalink's firmware, well actually the module itself, doesn't support 2006 Jeep Grand Cherokee with UConnect. Granted the steering wheel, amp fader, and other audio features are supported. This still doesn't change the fact you're paying for a feature that doesn't work and sold as if it does. I spoke to a rep at iDatalink, and she apologized about the delay on the front page of their website. Crutchfield may not even be aware of this, but it's definitely something to note if you were indeed looking to keep that stuff going.

Pros: Customer service was great.

Cons: UConnect advertised to work on 06 Jeep Grand Cherokee doesn't.

Installed with DNX891HD in 2006 Chrysler 300c

Joe Turner from Gardendale, AL on 12/9/2014

2006 Chrysler 300
Crutchfield Customer Review (What's this?)

I installed this unit with a Kenwood DNX891HD in a 2006 Chrysler 300c. I couldn't find a lot of information specific to my car, so I figured I would add some notes here: 1. You can go to the iDatalink website and run a simulator for your car that will show you what will work once you program it. This was very helpful. 2. I had to call customer service because the additional harness that is necessary had been wired incorrectly for the ODBII connectors. They were very helpful and knew exactly what the problem was, and they sent me directions on how to re-pin it. 3. This does allow for gauges to show up on the 2006 300c. It also would have allowed me to keep my uconnect. I bypassed the factory amp, and you can turn the factory amp back on from within the Kenwood interface. If you bypass the factory amp, it bypasses the factory speakers, making it unnecessary to cut all of their connections when adding all new amps. You can change many of the other parameters as well. 4. Be careful if you zip tie it inside the car. The reset button protrudes out, and my zip tie got stuck over the button, causing it to continuously reset, which made my system not display.

Pros: Works great!

Cons: They should have provided information about the mis-pinned wires. When I called Crutchfield they knew nothing about it, but when I called iDatalink they knew immediately. You would think they would spread the word to their dealers. I also wish the reset button was recessed.

Overall a great and highly recommended product if you want to use your vehicle's external steering wheel controls. Worth the money no doubt!

Installed in my 09 Silverado with the Kenwood DNX891HD head unit. This unit work as advertised, fairly easy to flash the Maestro to match your vehicle. Just make sure you flash this little unit with the correct parameters. For example if your vehicle does not have any digital displays ie.(speedometer) then don't tell the Maestro you want gauges displayed on your radio, it locked up my radio and resetting did not even work had to disconnect battery to reset radio. Thanks to a call to Crutchfield and some trial and error got system to perform as expected.

This unit integrated my Pioneer 4000nex into my 2006 Dodge Magnum SRT8 almost perfectly. I did loose fade capabilities, because the factory amplifier only accepts inputs from the rear speakers. I also have to switch the rear with the front speaker wires in the harness to be able to hear phone calls. I wish the Maestro could compensate for this. However I was able to retain my advanced EVIC display which I am thrilled about!

Pros: Makes installation easy! Retains most functions.

Cons: Lost Fade capabilities. (firmware update?) Need to switch wires to function properly (for phone calls) Loose radio station info on EVIC display.

Not As Advertised!

SamA from El Paso, TX on 8/5/2014

Crutchfield Customer Review (What's this?)

It took me some time before I purchased this product. Maybe that is why I only rated it 3 stars. Advertised: purchase this product to "retain steering wheel controls and factory amp" This is not accurate at all. I should have listened to some of the lower rated reviews, but you always think some people are just upset. I had this professionally installed by a certified Kenwood Dealer along with a Kenwood 691HD head unit. The steering wheel controls do work but have been altered to do different things other than what the factory settings were. The turn signals and hazards have been altered to some annoying clank and the timing is completely off. So, basically my personal opinion: is that if I knew I would have to listen to the generic fake chimes that this unit is producing, and the controls this activates on the steering wheel, I would have never bought this thing and lost the controls and chimes. Shame on Crutchfield for what I believe is making this unit seem better that what it is and not being forth coming with the information that it is basically a toss up on the interaction at feature when properly installed.

Pros: Your head unit works.

Cons: Not as advertised!

Crutchfield response on August 18, 2014 It's too bad the ADS-MRR didn't work out for you. For other people in this situation, the button assignments can be re-programmed to suit your needs. The installer could've "re-flashed" the device to change those settings for you. There's not much to be done about the sound of the chimes and turn signals, but repositioning the chime speaker might've helped decrease the delay. What's more, since you have an iDatalink compatible Kenwood receiver, in the stereo's Setup menu, you can adjust the door chime volume directly. This also might help alleviate the delay.

Use this unit in our 2014 GMC Savana Van. It was the only one that assured we retained all of our door chimes and lighs on warning signals.

Pros: Plug and play

Cons: none

Must have!

Crutchfield Customer Review (What's this?)

If you have any kind of factory hands free/steering wheel controls, you absolutely MUST get one of these. The ease of integration and programming, plus the added features and of course retaining the factory controls and SYNC in my case, is invaluable.

Pros: Easy to install and use! Excellent customer support from the MFG!

Cons: None.

Crutchfield Customer Review (What's this?)

This adapter works great and the customer support is awesome. I installed this in a 2006 Ram and still having problems with it not tuning my factory amp on every time. But, this thing will integrate your factory bells and whistles very nicely. It is highly customizable and seems to be very stable even in the N. Ca summer heat.

Pros: Easy to set up Customizable

Cons: Have to remove to re-flash Have to have a windows machine to flash

Nice, but not as advertised

2013 Jeep Wrangler Unlimited
Crutchfield Customer Review (What's this?)

The device has numerous options with the programmable interface, but does not have any additional features over the competition in my 2013 Jeep Wrangler. Several desirable features do not work from the device despite complete, correct connections as per the instructions and correct harness (sold seperate)

Pros: Easily customizable buttons

Cons: Does not correctly translate illumination wire, radio stays fully bright all the time Does not detect reverse, had to go around the device to the reverse light switch. Does not translate speed pulse, making problems with A/V and GPS Navigation. Does not pass Track or GPS information back to the Chrysler Uconnect EVIC display, an OEM function.

Crutchfield response on July 22, 2014 Unfortunately, the last issue mentioned (sending track or GPS information back to the Uconnect display) can't be fixed. According to our Techs, that's not something that can be done once you install almost any aftermarket stereo. Our Tech Support team has reached out to the customer to see they can help solve some of the other problems. Remember, lifetime Tech Support comes free with any Crutchfield purchase.

2011 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

I installed this on a 2011 Silverado and everything worked except the Truck Bluetooth. I'm very happy with this purchase. I did not have to cut any wires on my truck.

Pros: Didn't have to splice any wires on my truck. Programming the unit for my truck was very easy......

Cons: Factory Bluetooth didn't work and I didn't like the factory sirius interface with the Kenwood. The station or title didn't show up on the screen. The only information was the channel number. I installed an aftermarket satellite tuner and it worked much better.

Everything Works!

Crutchfield Customer Review (What's this?)

Allowed me to continue to use my steering wheel controls. Down the road if I upgrade head units I'd like to see it's other capabilites.

Pros: Fairly easy to install. Allowed me to retain current functions

Cons: None so far.

Just like factory

Crutchfield Customer Review (What's this?)

The idatalink Maestro worked as advertised. I had to do a little soldering and what not but no problems. Installed it and it worked. The only thing that was an inconvenience was the lack of Apple support. But luckily the neighbor came through and let me use his (PC) laptop to do the programming. Other than that, I had no problems and would recommend this product.

Pros: Simple to program. Adapter is fairly small and easy to tuck out of the way.

Cons: Must have a PC to program. And a little labor intensive, not a plug and play device.

Lots of functions for such a little box

Todd from TX on 6/30/2014

Crutchfield Customer Review (What's this?)

Great product for plug and play and allows my to view a lot of the gauges for my Silverado and see ce codes when thrown. The current model that I have does have a few annoying factors with one of the ways it gets hooked up. Whenever the blinker clicks it cuts out the front left speaker which is annoying. I found out how to turn off the alarm but other alarms from car like low gas or seatbelt also cuts off the speaker.

Pros: Can see lots of gauges from truck, very programmable.

Cons: Sound cut off is very annoying however this model is now discontinued so the replacement may have fixed that.

Neat but not ready for prime time

762x51 from Greensboro, NC on 6/16/2014

Crutchfield Customer Review (What's this?)

I bought this to integrate a Kenwood DNX691DX into my 2010 GMC Sierra XFE and while it did integrate most of the functions, missing were some of the chimes (door open for example) and reasonable integration for the OEM XM receiver. If you select the XM receiver from the main menu then you will get a message to check the receiver. You have to go to the first sub menu, select "My Sierra", then XM radio from that screen to get the XM radio to work. Very distracting while driving!! Another quirk is the chimes that do work... If you adjust the chime volume so it doesn't blast you out of the car then you cannot hear the turn signal reminder.

Pros: Makes connecting a radio to your car/truck somewhat easy and it will pass some of the vehicle's data to the radio.

Cons: Finding documentation and connection (maestro - radio - vehicle) data is difficult. iDataLink's WEB site isn't easy to navigate but with patience you will eventually find the info you need to install their device.

Nissan Integration iDatalink Maestro ADS-MRR

2011 Nissan Maxima
Crutchfield Customer Review (What's this?)

This is a great product. I was able to integrate the Maestro Rr with my new Kenwood DNX891 head unit and keep my Steering controls. I am able to view gages and ODBII Engine diagnostics on the Kenwood until. I was able to easily link the Kenwood until the factory Bose amplifiers / Speakers

Pros: Easy instructions for connections based on vehicle type. The firmware flashing process for vehicle was easy to follow. Nice having the ability to view vehicle info on my head until Read/Reset Check Engine Codes. I can view dash gauges. My steering wheels controls work great and can be reprogramed to accommodate different functionality.

Cons: I had to call Crutchfield connection points for reverse and parking brake as they were not provided in the harness. The Crutch filed web site said the Maestro Rr was not compatible with my 2011 Nissan Maxima even though it's fully supported by ADS Idatalink.

2007 Chevrolet Avalanche
Crutchfield Customer Review (What's this?)

I'm on day 5 and the unit still does not work. I installed the Maestro RR with the suggested GM harness, a Pioneer AVIC-6000NEX, in a 2007 Chevy Avalanche. After the initial install, the steering wheel controls worked, but I could not get my dash lights to turn off, even when the vehicle was off. The speaker output was almost nonexistent and the amp turn on was blowing fuses. After several hours of going over the wiring, and in fear of blowing up my amp and head unit, I put the install on hold. I called IDATA in the morning and the tech told me that the pink and white wire was seated incorrectly on their harness. I removed the wire and put it into the correct pin placement. The tech also told me to remove the "blockers "(an inline series of caps) from the speaker wire. These steps seemed to do the trick. However, after about 5 minutes the volume began to increase and decrease all on its own. I had to turn the volume down manually. Then the steering wheel controls ceased to work at all. I called tech support again and they told me that I needed to solder a 47 ohm resister on the red wire of the control plug. I performed that task. The volume still has a mind of its own and the steering wheel controls do not respond. I'm not certain what they will suggest next. I'm incredibly frustrated. IDATA seems to desire to place blame on Pioneer. I ha
