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, 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) 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, 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.
  • 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.

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.

Product Highlights:

  • allows installation of a new car stereo in select 2006-up Ford, Chrysler, GM, and VW vehicles
  • works with required vehicle-specific harness (sold separately) to retain factory steering wheel audio controls, retain the factory amp if present, and integrate all car stereo connections
  • retains factory convenience features (OnStar, SYNC, Uconnect, and more) with select Kenwood, Alpine, and Pioneer touchscreen receivers
  • displays engine performance data on touchscreen with select Kenwood and Alpine navigation receivers
  • dimensions: 4-1/8"W x 3/4"H x 2-7/8"D
  • warranty: 1 year
  • Our 60-day money-back guarantee

Will not work 100% with Pioneer AVIC-4100NEX

Written By Anonymous, California on Saturday, September 19, 2015

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.

Great Product!

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.

Crutchfield Customer Review (What's this?)

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.

Pros: Everything works.

Cons: Crap instructions for wiring. Misleading flashing instructions on their website led to re-flashing the device once.

Amazing integration

I was pleasantly surprised how much integration the kit provided to the factory APIs on my Charger. It allows my Kenwood 9702S to display feeds on the engine and tire pressure that I didn't realize the car could do. And the steering wheel controls are everything the kit promised.

Written By TedS, New York on Tuesday, September 08, 2015

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.

99% Great...installed on 2013 F150

Written By Scott, Ohio on Monday, July 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.

Great way to integrate factory controls with aftermarket stereo. Retains all factory features and adds so much more!

Pros: Small size, plug and play Easy to use interface online to program.

Cons: Can be difficult to get set up the first time, being installed behind the dash doing multiple resets before all the kinks are worked out.

Not quite what I expected

Written By Jen, South Carolina on Tuesday, July 14, 2015

Crutchfield Customer Review (What's this?)

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

The iDatalink Maestro will allow you to retain all your factory settings with your receiver. I have a Kenwood DDX5902 installed and was able to retain my steering whell controls, backup camera and able to bpyass the Ford Sync and use the receiver to control my cell phone.

Pros: Retained all the factory features

Cons: The AC On/Off Button does not work from touchscreen

Crutchfield Customer Review (What's this?)

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.

Pros: Easy to install, clear instructions, does what it's supposed to.

Cons: None.

idatalink doesn't deliver.

Written By Postman, Florida on Sunday, June 21, 2015

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.

I installed this myself and it was not really that hard to do. Just follow instructions. Crutchfield advisers and the support from idatalink made this rather easy. Kept all of my factory settings with this product. I would add that one must have some basic electrical and installation experience to do this.

Pros: Great support. Easy to install.

Cons: None.

Awsome product

Written By Greg, Texas on Monday, June 08, 2015

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.

Interesting device. Works as described.

Pros: Easy steering wheel control interface.

Cons: Programming. First off you must have a pc/windows to program, seriously disappointing. Second it asks for the pioneer radio serial number which it needs to communicate to the radio, that is incorrect it needs the access PIN number from the radio, which you need to power up the radio to access.

Written By david, Alabama on Friday, April 10, 2015

Crutchfield Customer Review (What's this?)

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

So confusing

Written By Joey, Iowa on Thursday, April 09, 2015

Crutchfield Customer Review (What's this?)

The idatalink system is amazing and works just like advertised... But getting to the point of having it work 100% takes a bit of work.

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.

bulky unreliable

Written By Howard P, Oklahoma on Tuesday, April 07, 2015

Crutchfield Customer Review (What's this?)

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.

Crutchfield Customer Review (What's this?)

The set up states that you need to flash the module with a computer running windows 7 or earlier. All my computers are older then 3 years old and none of them have that old of an operating system on them! I spent day looking for a friend that I could borrow a vintage computer from with no luck. I ended up using my windows 8 computer and it seemed to work fine. It's not a perfect fit and solution if you want everything to work like stock but it's acceptable! customer service is 9-5 m-f so if your installing on a weekend there will be no support!

Pros: It's a good patch

Cons: Loss of some stock features. Set up. Customer service hours

2008 GMC Sierra Installation

Written By John, Tennessee on Friday, April 03, 2015

Crutchfield Customer Review (What's this?)

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

Written By Zach, Anchorage, AK on Wednesday, April 01, 2015

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

Written By cs1981, Texas on Tuesday, March 31, 2015

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

Written By gatorguy, Kokomo, Indiana on Saturday, March 28, 2015

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.

Install in 14 Wrangler LTD

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.

A Little Daunting

Written By Pensive Guardian, Chicago on Sunday, March 22, 2015

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.

Works great in my new Jeep. A little tricky to download off of their website, but after that it was very simple!

Pros: Has everything needed to utilize all your factory controls and features.

Cons: Tricky website programming.

iDatalink Maestro ADS-MRR Interface Module

Installed in my Jeep Wrangler. Great product did what it was suppose to.

Pros: Worked great. Good instructions.

Cons: A lot of wires.

No Music from the Maestro

Written By 2010Mustang, Honolulu, HI on Friday, March 13, 2015

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

Written By Darin, Denver, CO on Monday, March 09, 2015

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 Monday, 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.

Easy Install

Written By BrentL, Hertford, North Carolina on Saturday, February 28, 2015

Crutchfield Customer Review (What's this?)

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

Written By TomC, Chesapeake VA on Tuesday, February 24, 2015

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

Written By DaveK, Utah on Sunday, February 08, 2015

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%

Written By Cory, Bakersfield, CS on Monday, February 02, 2015

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

Written By Rob, Michigan on Sunday, February 01, 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!

Works Great!!
