PAC's RadioPRO5 RP5-GM11 wiring interface enables you to install a new car stereo and retain useful factory functions in your 2000-up GM vehicle. You can upgrade to the higher sound quality of an aftermarket receiver while maintaining your factory-installed OnStar®, factory amplifier, Bluetooth®, safety warning chimes, and the Retained Accessory Power (RAP) if equipped. In some vehicles, you can also retain your factory rear seat entertainment system. If you're installing a navigation receiver, this interface also features the Vehicle Speed Sensor (VSS), parking brake, and reverse connections you need.

Easy to install, works as advertised, I did have problems with the he backup camera circuit staying hot all the time. Had to resort to wiring camera drectly into vehicles reverse sensor. Call Crutchfield and they told exactly where to locate wires and what color.

Pros: it does 95% of what it says it will do. It works.

Cons: Control box is too big. Makes it hard to fit in Dash. Reverse camera function didn't work.

This kit worked perfectly on my 2003 GMC Sierra with no other changes required. All steering wheel controls worked and the door chime is on a long enough tether to mount under the dash in a location that it's still audible.

Pros: Retains all steering wheel control functions. Audible door chime.

Cons: Would be nice to have a bit of a longer harness.

Crutchfield Customer Review (What's this?)

I was worried that with all the plugging in and adjusting (not to mention soldering a dozen wires for the radio installation) that something just wouldn't work right. But I assembled it all and it worked perfectly. I have steering wheel control just like the stock radio. I also bought the chime since the stock radio is what generated the annoying beep every time you open the door with keys in the ignition. Here's a tip: If it's too loud, put a piece of tape over about 90% of the little speaker hole and it will cut the volume down. Experiment before you put it all away behind the dash and you can adjust the volume based on how much of the hole you cover.

Crutchfield Customer Review (What's this?)

I bought this to integrate my steering wheel control with the new deck. I installed the deck one day and had questions on this. However, they had closed for the day. When I called technical support the following day, they gave me a few things to try (like reprogram the unit). I am working during the day and could only do it after work. By the time I could try a couple things with no luck, customer service was closed again. I finally just put everything back together without it working. If you may need help, install on a weekend.

Pros: Seems like a good product. Plug & Play.

Cons: Doesn't work. Not enough customer service.

I'm amazed someone actually still makes a product that works for a 12 year old Buick Redezvous. This thing makes the self install much easier. I was confused by a couple of technical issues, but PAC people were quick with a email response.

Cons: Instructions could be better written.

Worked perfectly. I was skeptical considering my truck is a 2004. It did include quite a bit of soldering, but that's nothing against this unit. I imagine any adapter would need all of those connections, and let's be honest, it's for a creature comfort and not necessity

Pros: Worked like a charm

this kit made installation of a Pioneer AVH-X3800BHS as simple as plug and play. wiring instructions were a bit basic, but easy enough to figure out how to hook it up. It retains the factory Bose system, onstar, and the dingers for open doors Ect. great value for the ease of install

Do Not Buy If You Have A Lux Bose Amp

Jason from White Post, VA on 2/11/2017

Let me start by saying I have a 2005 Cadillac Escalade EXT with a stock Lux Bose amp and Bose speakers. You can confirm if you have the Lux Bose amp by checking for Y91 in your glove box parts list. This PAC unit was nothing but problems from the start. With everything connected properly, half the speakers would either not work or would be super quiet. The speaker fading ability is also non-existent - you lose that from factory stock. However, the Most Annoying Part of this piece of crap PAC audio unit is that it has issues triggering the Lux Bose amp on start up. Sometimes but not every time, there would be no sound when I start the truck. The Only way to fix it was to turn the truck off and back on, needless to say it was extremely annoying. The only thing I could think of to fix this was to bypass the PAC box and wire the amp directly into the stock connector but that would require cutting into my factory wires and why should I have to do that when I purchased this product? I had contacted PAC audio and you guessed it, they never emailed me back. I ended up purchasing the Metra Axxess instead. With this unit, the speakers actually function as they should, the speaker fade works, dimming is possible, last but not least there is a System Remote Control (blue) wire to hook the amp to. This finally resolved the issue with the sound sometimes not coming on with startup. The Metra costs more because the steering wheel controls are separate but boy is it worth it. It actually fun

Pros: Nothing, it's garbage

Just what I needed to get an aftermarket radio in my 06 Sierra with Bose system. Everything still works as it did from the factory, which was a big deal for me. Nice, all in one interface for GM. If the steering wheel controls do not work try a different number on the unit for radio manufacturers. Sony is supposed to be 9, I had to use 8 on mine but it works great

Pros: Simple install, retains all factory functions with new radio, all in one design, plug and play.

Cons: A little bulky to cram in the dash behind the radio, door chime sound could be better

PAC unit was easy to install/interface with the factory harness and new stereo. Only one issue, the initial PAC unit was possibly defective as the speakers would cut out intermittently. No problem, as Technical Support was contacted and a replacement was sent in a quick and timely manner.

Crutchfield Customer Review (What's this?)

Used to install a new Pioneer DVD receiver in a 2004 Suburban with the factory RSE. This module does exactly what it is supposed to do. Instructions are easy to follow and everything just works. Used the RCA connections from the kit to hook up the audio from the factory DVD player to the new radio. My only wish is the wires were a little longer between the new deck and the interface box so I would have had a few more options for where to mount everything. It's a tight fit behind the deck, but I got it in and am very happy.

Pros: Retains all factory controls, allows factory DVD to connect audio to new deck, easy plug and play with good instructions.

Cons: Pigtails were a little short

Seemless installation. Awesome kit

2005 Yukon XL with Bose; Retains RSE, OnStar, and SWC

Eric from Yankton, SD on 12/1/2016

2005 GMC Yukon XL
Crutchfield Customer Review (What's this?)

Ordered this interface to use with Pioneer AVH-2800BS DVD receiver mainly because I wanted to retain the RSE for my kids. I have a 2005 Yukon XL with Bose system. First unit I received was defective. As soon as I plugged the interface harness into the vehicle harness(with key turned off), I heard a constant rapid clicking sound....like a bad blinker switch. Receiver would not turn on at all when key was turned. After consulting a Crutchfield's customer service rep, I found out this was a relay and that it was defective and shipped me a new interface. The second unit seems to working just fine so far. The RSE works just like it did before. The kids can watch their dvd's with headphones on or we can listen to it over the speaker system(Interface harness has RCA audio connectors that plug into back of head unit). The factory amplifier and subwoofer still work, and sound amazing now with the new head unit. Steering wheel controls still work pretty much the same as before right out of the box, or they can be programmed however you like. Connecting wires was simple, and the instructions are pretty clear. Once the interface is put together and connected to the receiver harness, the box and large mess of wires is hard to fit inside the dash. The chime sound could be better.

Pros: Retains RSE(headphones and speaker system); Retains factory amp and subwoofer; Retains steering wheel controls and OnStar; Easy connections and set-up.

Cons: 1st unit was defective and had to be replaced-raises concern for future quality issues; takes up a lot of space and is difficult to fit inside of dash even after removing support; chime sound isn't very good

Pros: Steering wheel controls work flawlessly Maintains warning chimes Maintains On-Star Rear radio controls control the radio Gives easy access to the wires you need to hookup Can re-map steering wheel controls to more useful functions

Cons: Lots of space required behind the radio to fit the box and additional cables Steering wheel programming requires access to the box

I would literally not have been able to install my new stereo without this. Kept all of the existing steering wheel controls, chimes, and Onstar functionality in my 2008 Corvette with no headaches.

Pros: Very easy to install. Instructions for the most part were very easy and in almost all cases the color of the wires directly corresponded to my Pioneer system. Did not have to program it as it was already programmed. Simple dial adjustment for stereo manufacturer.

Cons: Instructions do not adequately document the use of the brown "mute loop" wire. Called Crutchfield support and they quickly gave me the correct information I needed.

Made every thing work (controls on wheel and OnStar). Was very easy to hook up and didn't have to look at instructions (which I found in the box behind a piece of cardboard after I put in the dash). All the wires takes up lots of room behind unit, so make sure your dash has the room.

Pros: Made all the factory controls work like with the factory radio

Cons: Takes up lots of room in dash behind radio unit.

worked great, but all I did was connect the same color wires to each other with the great screw connectors you send me. I assume come cars require different hookups, but mine didn't. Including a blue-white wire mismarked as secondary control when it should have said amplifier, which your tech corrected in 2 min.

Pros: would be a big problem without it and those wonderful connectors, and your great tech team

Cons: why not connect the wires for us if they are are same color to color. But some must be different so I probably shouldn't complain.

This product was necessary for my car to keep the factory steering wheel, onstar and chimes. The new chime is pretty obnoxious but getting used to it. The box is pretty big especially fitting in the under the dash. Plugging into the box is difficult and sometimes feels you might break something trying to push it in.

Pros: After all said and done it works as it should just could be better in my opinion

Cons: Loud obnoxious chime, hard to plug into.

The wiring matrix from my GM to the Kenwood was flawless and reprogramming the steering controls was a breeze. I soldered all the connections using the PAC and Kenwood diagrams and everything worked perfect when I connected it.

Pros:

Cons: My truck has OnStar, so it would be nice to be able to program the OnStar button to work with the head unit. Also would be cool to be able to use the OnStar microphone. There is one issue. When turning on the stereo, I have to push the OnStar speak button on and off to get the sound coming out through the speakers.

2006 Chevrolet TrailBlazer
Crutchfield Customer Review (What's this?)

First, the installation instructions left a lot to be desired. Once the installation was complete, the steering controls still do not work properly. The stereo audio will only work if you push the On-star button "On" and then "Off", then the unit will power up and the sound comes on. I went to their website and it says to download a new program upgrade for the control unit. The download was a .puf file, whatever that is and the only way to open it was to go out on the internet and purchase a program that I would have to pay for to open and install it. I havent installed it yet, so I have no idea if its going to work or not.

Pros: None

Cons: Horrible instructions and doesn't work.

Crutchfield response on August 10, 2016 Jason, one of our Tech Support Specialists, reached out to Brent after researching his review and his order. He expressed to Brent that the likely culprit for the stereo turn-on issue is that the "amp remote" wire must be connected to the blue/white wire on the adapter he purchased. Also, he noted that PAC supplies a free download for the firmware updates for his adapter, and then he supplied a link to that tool. Jason also mentioned that Brent probably did not need this update for the successful installation of his radio. Lastly, Jason asked for the make and model of Brent's receiver, so that he could check compatibility of the steering wheel controls. Some radios are not compatible with steering wheel control interfaces, which is why it's helpful to check with an Advisor before you purchase car installation gear.

Crutchfield Customer Review (What's this?)

After opening the box and realizing that it wasn't going to be a plug in type of installation, I started to get frustrated. But after making the connection to a technician and he walked me through it all, I found that it wasn't as difficult as I was originally thinking. The only hiccup that I had after that, was that I failed to make one connection that I was able to quickly find and then everything started working as it should. Crutchfield technicians know how to fix issues.

Pros: The interface that was recommended for me, did everything that I was told that it would do. EX: Retaining all of my steering wheel controls, factory chime, etc.

Cons: I had originally only requested the interface and all the necessary components to install a stereo system that was gifted to me. After the sales tech had put that all together in a shopping cart for me, I called back and wanted to add an XM behind the dash tuner. Somewhere in the mix of not talking to my original sales tech I was given the wrong XM unit and it had to be returned and replaced. The original unit had a rebate and the replacement unit does not. That was disappointing to me.

Very nice

Crutchfield Customer Review (What's this?)

I was very happy on how quick it allowed me to connect an aftermarket head unit in my 2005 Escalade EXT. However, I paid extra for this one to insure that my steering wheel controls would work, but they did not. I called tech support and the said it may not be compatible with my unit. I could have saved almost $30 if I would have went with the one without steering wheel controls.

Pros: very easy and quick to install

Cons: Steering wheel controls did not work with my head unit.

Crutchfield response on August 9, 2016 After researching David's review, our Tech Support Specialist confirmed that this steering wheel control interface was incompatible with his stereo and issued him a refund. The steering wheel interfaces we sell work with the majority of car stereos we sell; however, we don't always have information on stereos we don't carry. It's a good idea to check the manual for the interface you're considering or contact one of our Advisors to make sure.

Installed this about two weeks ago. I bought this unit to replace another interface( different company) that would work when it wanted to. So far works great. Have all of my steering wheel controls, buzzers, etc. Time will tell if this is a good product. Instructions are a little fuzzy, but if you have installed systems in the past, just use a little common sense and everything will connect properly. I probably would buy this again if I was in the same situation.

Pros: small size; wiring is of good length;

Cons: instructions could be more clear to understand on what wires to hook up. time will tell how this unit will last

Crutchfield Customer Review (What's this?)

I used to be an installer (before they offered vehicle-specific wiring harnesses), and this is the first time I installed an interface like this. It was just as easy as the passive wiring harness used in a typical install. Match up the wire, most if which were color to color, and plug it all in. It doesn't get any easier than this. I did have a small issue with understanding the instructions... Ultimately, when you are wiring this to a Bose system with factory amplifiers, you DO wire the speaker wire connections even though the harness has an RCA connection (that is for RSE input). The instructions just weren't 100% clear on that. It wasn't a deal-breaker though. I would buy this interface again.

Pros: Works great! Affordable! Easy to Install

Cons: Instructions could be a little more clear when wiring to an OEM amplified system, but this is a very minor gripe, not a deal breaker.

2005 GMC Sierra 2500/3500
Crutchfield Customer Review (What's this?)

Before purchasing this product so that I could keep my factory chime, OnStar, rear entertainment, and steering wheel controls, I read up about it and even read the installation instructions. I have to say that I was a bit nervous as the instructions seemed vague at points. However, after having this in hand, all of the items made much more sense. This PAC controller is now installed and works perfectly. My cautions to any who consider purchasing this are as follows: 1) the wiring harness connectors that clip into the blue PAC controller are quite difficult to get seated all the way. Make sure they are plugged in completely before putting your dash back together. I initially put my dash back together only to have issue with my head unit a day later. It turned out that one of my PAC controller wiring harness connectors was not completely clipped in and had wiggled out from road vibrations. 2) After solving issue 1 above, I had to take my unit out a second time. This time was because the DVD player. Turned out to be a wiring issue, but not due to negligence on my part. I looked on the PAC website and noticed that they had updated the wiring colors for the harness that goes to the head unit. However, the PAC controller I received had the previous version instructions which resulted in my wires being

Pros: works great

Cons: cheap harness connectors must look for updated wiring color codes on website because instructions may be for older PAC controllers

Crutchfield Customer Review (What's this?)

Two points - For what I considered to be a pretty expensive connection kit, I was bothered by the fact that I still had to sort out the individual wires in two wiring harnesses and use butt connectors to connect all the wires together. The physical size of the PAC box itself made getting the radio back into the dash very difficult. I was not going to cut metal struts inside the dash to get it in, but I thought I was going to have to return everything to keep from doing that.

Pros: Seems to work so far

Cons: Much more difficult installation than expected

advantus from Kearney, NE on 5/5/2016

2003 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Used this interface to install a Kenwood DDX373 double din in my '03 Silverado 1500HD and it is a huge time saver. Everything is plug-and-play basically. My advisor, Buck, advised me to get some of these connectors: http://www.crutchfield.com/p_669PP500/Posi-Products-Car-Stereo-Connectors.html?tp=61469 and those worked real well to connect the interface to the Kenwwod receiver. There are a lot of wires when you open the box, but don't sweat it. On my Kenwood, every wire coming out of the receiver had a matching wire on the interface. It was just a matter of stripping and connecting. The only thing I wasn't sure of, was the reverse camera power lead as I installed a backup camera at the same time. On the PAC unit, there were three wires separate from the rest that were labeled for Nav. My Kenwood doesn't have navigation so it wasn't clear that the green wire bundled in the Nav label was to connect to the purple/white wire on the Kenwood. The door chime is a little different from the stock Chevy chime, but you can control the volume by turning a dial on the interface. My Kenwood indicated that I wouldn't have to cut the dash support in the back of the double din opening, but I ended up having to anyway just to fit all the wires and the PAC unit in the back. Once that was out there is plenty of room to slide everything in. All vehicle functions were retained such as OnStar, steering wheel controls, etc. Works great and highly recommended.

Pros: saves time, easy to install, works, wiring diagram easy to decipher

Cons: none

This kit along with my Kenwood DPX592 head unit works flawlessly with the Bose system in my '05 tahoe. The only thing it doesn't tell you is that the blue and white power antenna wire, is also the wire for the amplifier in the chevy/bose system...just tie it to the corresponding colored wire on the head unit. The only negative thing about this unit is the sound of the chime just doesn't seem right. I may go back in and unplug it completely, the lowest volume setting is plenty enough too.

Pros: Works like a charm for all stock controls.

Cons: Removed dash to fit everything in without just cramming it in. Chime sounds weird.

Crutchfield Customer Review (What's this?)

You could spend the better part of a day hacking up your wiring harness, chasing wires, and then splicing them all and STILL not have all the factory bells and whistles you had prior to the install. Literally bells and whistles. If you have a factory amp like a Bose or Monsoon, this is a life saver. Without it you'll either have a really loud system that will eventually blow speakers or you'll have to spend even more time splicing wires to remove the factory amp. The better option is to uncork some money from your wallet, buy this interface and retain all of your factory options and safety features. Your time is worth something, so don't waste it when this can be installed in a few minutes.

Pros: Easy to install. Retains factory options and works with factory amps. Allows you to return to stock configuration pretty easily if you ever want to save your equipment when you get rid of the vehicle.

Cons: Takes up some space inside the dash...can be a pain to stuff behind your head unit.

Crutchfield Customer Review (What's this?)

I used this in my 06 GMC Sierra with a factory Bose system, steering wheel controls and OnStar. I wasn't concerned about retaining OnStar, but the steering wheels controls and Bose amp are what I wanted to keep and this retains all three. The module installation is really straight forward and the directions are clear and concise. Basically, you match the wires from the module to the new stereo harness by color and set the module to the manufacturer of the head unit and that was it. The module plugs into the factory plugs in the dash with no issue. Some people have stated that they needed to program the module for the steering wheel controls, but I didn't have to so I can't comment on the difficulty in doing that. It's only been a few days, but so far so good and honestly, the hardest part was trying to fit all the wiring behind the head unit in the dash. I'm very pleased with this and would highly recommend it.

Pros: Ease of installation and it does why it's meant to do

Cons: None yet.

Crutchfield Customer Review (What's this?)

I like that it was easy to hook up and the directions were pretty easy to understand but the device seems to be made cheaply. I actually had to get a replacement because the first one only lasted for 2 days. I contacted crutchfield and they shipped one out very quickly. I determined that the first one was bad because the door chimes didnt work and the stereo would randomly switch between all the inputs (reverse/bluetooth/radio) and there was no audio.

Pros: easy to hook up and does what its advertised.

Cons: Made cheap and has a high price tag. The door chimes sound very cheap(like a Ford). takes up a lot of space making it hard to get a double din back into the dash. if you dont have a lot of room this may not work for you.

good fit. works great!!

works great in my 03 GMC Sierra w bose system. the pac cables are a direct fit so no problems trying to figure it out. instructions clear. just read them for your application. I have the alpine cde153bt. no programming was needed and all the swc buttons work as described. I'm really happy with this purchase. on star maintained. my Bluetooth hf works great through speaker system. nice product.

Pros: everything worked right the first time.

Cons: no cons. when ur all comes together and does what it's supposed to

It works

Dan from Louisiana on 1/6/2016

Crutchfield Customer Review (What's this?)

It works. But it sure takes up a lot of space in your dash.

Pros: So far it works as it should - no additional programming needed.

Cons: Takes up space behind head unit that I had a hard time making work.

Whole Lotta stuff

Duke from North Carolina on 1/3/2016

2005 Chevrolet Avalanche
Crutchfield Customer Review (What's this?)

This was for my 05 Avalanche and works like it should. There is a lot of stuff to cram in that small space and still fit the radio. The last time I did any stereo work on a vehicle I only had to hook up 12 wires including the 8 speaker wires so I was a little apprehensive about trying this especially when I saw all of the stuff with this kit. The kit is very easy to hook up, adjust and use. This kit is a no brainer for hooking up these complex systems.

Pros: Very easy to use, good directions

Cons: A lot of things to get crammed into a small space and still get the radio in.

Gary W from Woodlyn, Pennsylvania on 11/23/2015

2006 Chevrolet Tahoe
Crutchfield Customer Review (What's this?)

Works just as described. Allows use of factory steering wheel controls. Easy to install and use.

Pros: Easy installation. Retains steering wheel controls. Adjustable chime volume.

Cons: Large box and lots of wires are a bit of a pain to stuff in the dash.

As advertised....

MC from Kansas on 11/12/2015

2003 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

Installed in a 03 Silverado and it works as advertised. Retained functionality of all factory steering wheel buttons and it makes the install "almost" plug and play. The basic receiver wires do have to be spliced (one for one) into the GM11 unit connector but with minimal wiring skills this is not tough. It is the heart of the install so take your time, do it right and it will do what it claims and likely last as long as you own it.

Pros: Allows for OEM functionality of steering wheel controls and minimizes wire splicing.

Cons: If I have to list a con, it would be the shear bulk of it all. In my case, room behind the receiver was limited and getting all the wiring tucked back into the dash was a bit of a challenge. Still, WAY more of a benefit than this small issue.

Works fine once installed correctly

CactusKid from North Carolina on 10/26/2015

2005 Chevrolet Tahoe
Crutchfield Customer Review (What's this?)

This adapter plugs right into the factory harness and provides all the factory controls from the steering wheel controls as well as the factory rear DVD system. Only draw back is it does not tie into the existing factory microphone so be sure to hook up the mic that comes with your tuner if you want to make hands-free calls.

Pros: All factory controls work.

Cons: Maybe difficult to figure out exact wiring hook ups without some guidance.

2003 GMC Envoy XL
Crutchfield Customer Review (What's this?)

I used this as suggested by Crutchfield to install a Pioneer headunit in my 2003 GMC Envoy. It not only made the unit install a breeze, it made it possible to retain the steering wheel controls. Everything worked as described. Would recommend it to anyone installing an upgrade.

Pros: Easy to use, made installation easy. I have not had any lag in steering wheel controls as some others have described.

Cons: None.

2002 Trailblazer - easy install everything works except for default steering wheel button functions. Volume buttons work as normal but "next" and FM/AM buttons do not have the factory functions. That being said I have not tried to manually program the steering wheel controls and the instructions state clearly how to.

Pros: Easy install, retains factory features

Cons: SWC "next" and FM/AM buttons need to be programmed for 2002 Trailblazer.

Crutchfield Customer Review (What's this?)

Adapted to the stock harness easily. Could be designed smaller. Worked fine except the steering wheel controls were not exactly like before.

Pros: Nice clean design everything plugs in easily but snug.

Cons: The steering wheel controls were not 100% equal to stock. The mute button on the steering wheel did not work anymore. The volume control worked but for swtching inputs and up / down presets the controls were mixed up.

Works Well

This product is pretty easy to install. The instructions are a little unclear but workable. You will need to have to connect each wire manually. All the controls work as expected. I have not tested the OnStar since I have no subscription.

Pros: Works well and installs fine.

Cons: Need to connect wires from the unit interface to the head unit interface. Documentation is not very clear.

Lake_effect from Michigan on 6/29/2015

Crutchfield Customer Review (What's this?)

It went together just as it says. I ran into an issue because I am running "for now" a Alpine head with the factory monsoon amp. After playing with the wires and troubleshooting over the phone you need to hook up the amp turn on to the monsoon amp. The steering wheel controls needed to be reprogram and I don't have all of the steering wheel controls I lost 1. All in all I'm happy that i spent the little extra to get it well worth it if you want to keep the controls.

Pros:

Cons:

Decent product, great service by Crutchfield!

DanL from Wyoming on 6/27/2015

Crutchfield Customer Review (What's this?)

I purchased this interface along with my Kenwood Excelon DDX492. The first unit I received was defective- the steering wheel controls would not work. After thorough testing with Justin in Tech Support (who was an excellent help), we found that the interface itself (blue box) was not sending any signals. Justin quickly shipped a new unit my way, and I swapped the interfaces out. The new interface works just fine, and sounds great. My only (minor) complaints are that the chime module is very annoying and cheap sounding, and the steering wheel controls are not as responsive as they were when my factory unit was installed. However, the chime module ships with the volume cranked, and can be turned down. The change in responsiveness isn't a huge deal, just something I noticed.

Pros: Crutchfield tech support and customer service!

Cons: Chime is annoying, and steering wheel controls aren't as responsive as they were with the factory stereo.

Missing Parts - Buyer Beware

RAD from Alabama on 6/20/2015

2005 Chevrolet Tahoe
Crutchfield Customer Review (What's this?)

Bought this adapter for a Father's Day install and received it on a Friday afternoon before the big day. Opened the shipping box and subsequent interface box only to find half of the parts missing. Upon further inspection, the interface box looked like it had been previously opened. Called Crutchfield for a replacement and the rep was helpful and understanding, however, I still won't be able to get the radio in for Father's Day because the distribution center isn't opened on the weekends. So much for the surprise - way to go Crutchfield! I haven't checked the radio I bought yet, I was too mad after finding the problems with the interface but that will be next.

Pros: Will review further when I actually get a complete interface kit.

Cons:

Harness

Worst Instruction Set Ever

Dubtown Dad from West Virginia on 6/14/2015

Crutchfield Customer Review (What's this?)

The product itself seams to work OK but the instructions with the unit are terrible with little to no help online. Typically that is not a problem with Crutchfield because their experienced technicians put together great instructions to help guide the customer. In this case the Crutchfield instructions were as bad as the manufacturers and each call to the tech line produced a different answer as to how to make this work. Finally after 12+ hours of screwing with this thing I was able to get it to work with the steering wheel controls on a 2002 Chevy Monte Carlo.

Pros: interface will work

Cons: instructions, Instructions, INSTRUCTIONS

Worked first time out. Some wires like the NAV and Mute did not need to be connected, a lttle confusing, but other than that, wiring radio harness to the RP5 was straight forward. Everything works like it should

Cons: Directions could be just a little more clear.

Crutchfield Customer Review (What's this?)

Great radio! Works great in my 2003 chevy Impala. Did not loose the functions of resetting oil & low tire pressure (they had to be reset through the factory radio). You use a combination of gas/brake pedal to reset. Works perfectly with my iPhone 6 Plus. You must have the steering wheel adapter (for factory steering wheel controls). You do have to manually set the buttons, but it works outstanding well.

Pros: Everything

Cons: You will probably have to manually set buttons. If you follow instructions it's no biggie.

SB from Fort Bragg, CA on 5/27/2015

2005 Chevrolet Silverado 1500
Crutchfield Customer Review (What's this?)

So this all worked for our steering wheel, programming was easy, and everything works. I have no experience with stereos or their installation...this was a surprise for my husband and I did the installation (Bad idea? Maybe). So...I didn't realize I would have to strip and join all the wires, I thought it would just be plugging things in. I appreciated that there was a "key" in the instructions that defined each color wire, thanks to this I knew that some didn't need to be dealt with. So that was interesting. But if I can do it, and everything works, then I say this deserves 5 stars!

Pros: Everything works, love the steering wheel set up.

Cons: Stripping and joining wires wasn't expected, but maybe that's normal. (I wouldn't know.)

Great addition to the install in my 2006 Silverado 1500. Used crimp connections to the head unit wiring harness, fit right into the dash. One major recommendation so you don't have to tare it all apart, turn the chime to the lowest level!

Pros: Makes install a snap Steering wheel controls still work (if the head unit supports it) Still have the factory sub!

Cons:
