2007 Envoy Denali

Crutchfield customer from Sealy, TX on 9/16/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

If you hame a GM vehicle this is the simplistic interface to retain almost all the factory options others don't. Thanks

Pros: Comes complete

Cons: Still have to solder to radio harness they should make a complete plug and play for most vehicles

White noise and horrible chime.

Crutchfield customer from Colorado Spgs, CO on 9/11/2019

2005 Chevrolet Silverado 2500/3500

Verified customer (What's this?)
Verified employee purchase (What's this?)

The vehicle warming chime that this "retains" is horrendous. It's a loud digital chirp that is just torture on the ears. I'm going to leave it disconnected because no one in the car can stand it. There is also some white noise that this generates through the stereo. It seems to be a bad or weak ground connection...

Pros: Easy to plug in

Cons: White noise and unbearable warning chime

Crutchfield response on 9/11/2019

Originally tried the quick wire connectors, but they came loose and caused speaker crackling. Soldered the connections and have perfect sound. It also made more room to stuff the wires behind the stereo.

Works great on 2003 H2

Crutchfield customer from Newbern, TN on 8/5/2019

2003 Hummer H2

Verified customer (What's this?)
Verified employee purchase (What's this?)

This kit made my install so much easier. Tearing apart the dash to get the radio in was bad enough. If I didn't have this simple kit to install it, I would have been throwing things. ha. I paid the extra $24.99 to have Crutchfield do the extra wiring for me, and it was perfect. I am a female that does quite a bit of minor mechanic work and installed this in my 2003 H2 Hummer. I don't normally install stereos, but since this was my own, I decided I would. I had to call Crutchfield twice for minor help with wires, and they were super helpful! I would absolutely recommend getting the wiring kit and having them wire it together for you. It made my day! Thanks!

Terrible device. Don't buy. Crutchfield replaced first unit and now with 2nd unit, problem still exists where the PAC module will not control the steering wheel controls. They work intermittently and do random things. I also spoke with PAC Tech Support and went through all protocols with no luck. Finally, now after 2 months of issues decided to go with Crux device and Crutchfield agreed. Crux device has worked good. 2004 Chevrolet Suburban

This is a necessity for factory integration. Also , if you choose to have Crutchfield wire it up, it saves you about 2 hours of tracing and reading over manuals and diagrams. When I received it with my order, it was a plug and play operation and took about 20 minutes to get it all hooked up.

Pros:

Cons: If you do the wiring yourself, the diagrams and manuals get a little overwhelming and confusing.

Works as advertised with the bose system in the 2010 Corvette GS. But, it's LOUD as hell, turn it way down and the beep is obnoxious, it's not a clean beep, it sounds like it blew the little speaker out, it's a grimy beep.

Pros: Works perfectly.

Cons: Beeps (door open , seat belt beeps) are not a clean beep, it's kind of obnoxious.

Worked like a charm. I had to manually program the interface to work my steering wheel controls but with Crutchfield customer services it was easy. Check all the controls prior to putting everything back together so you don't have to take it back apart to program the device.

Crutchfield customer from Elkhart, IN on 5/16/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I installed this along with a Soundstream VRCP-65 in my 2005 Tahoe z71 with factory Bose (regular Bose amp, not the lux amp) system. I was able to maintain OnStar, Bose sound system and steering wheel controls. I did have trouble getting the SWCs to work, but a quick call to Crutchfield's awesome tech support helped me reset the RP5-GM11 interface and then select programming #3 to get them to work. If you're trying to keep your factory GM system and just upgrade the head unit, I highly recommend!

Pros: Factory SWCs, Factory Bose, Factory OnStar

Cons: Programming SWCs can be a bit finicky.

Properly installed unit will not run steering wheel controls on my vehicle. Which is the whole point I bought it in the first place. Not happy with Crutchfield recommending this for my vehicle.

Easily spliced the nest of wires and set it for my brand of radio. One thing that I didn't know, was that my truck runs through a factory amp and according to Crutchfield tech support (I can't remember who I talked to), there is no fader control with this. It's either 50/50 sound through front and rear, or 100% front.

Pros: Wiring was a snap Steering wheel controls work

Cons: Lost fader control Plug for SWC is a loose fit

Tried many things Tech Support suggested, finally had to put off the install (and drove around with half the dash apart) waiting for a replacement. After the same thing happening with my remote start, not sold any longer on the price paid for the products.

Pros: Replacement seems to work fine.

Cons: Didn't work out of the box. Wasted time on Tech Support and waiting for a replacement part.

Highly recommended for cars with integrated systems. This kit allowed me to keep the steering wheel controls, rear entertainment system, on-star, and other intigrated systems along with my new stereo.

Pros: Allows you to keep intigrated features such as steering wheel controls, rear entertainment systems, and other systems that came with your vehicle.

Cons: In dashboards with limited space, this unit takes up a lot of space and can be more complicated to install.

I mean this thing does work, but it's a rats nest and a half. I have all the factory controls and chimes working after installing a new Kenwood receiver and it all runs through the factory amp and does what it says it will do. I'm giving it 3 stars for the ridiculous wiring mess it brings with it though. If they could solve that then this would be a 5 star product for me. The one thing I can't figure out though is the chime module, either I got lucky or maybe it's for a different model car not sure but I didn't need it as I still have all my factory chimes and leaving it plugged in gave me two different chimes at the same time. Kind of nice that I didn't need it because that was one less thing to have to stuff under the dash. Just worth mentioning so you can test and see for yourself if you really need it or not for your application.

Pros: Works

Cons: Rats nest

Expensive and it's required

Crutchfield customer from Lansing, MI on 3/14/2019

2005 GMC Yukon

Verified customer (What's this?)
Verified employee purchase (What's this?)

You're already spending $500+ on a radio, but wait, here's another $85 that's required. The unit is roughly 3" square and you have to stuff that behind your new radio somewhere along with all the pigtails coming out of the radio. Add to that 3 harnesses that come out of 3 different sides of the unit. It would have been nice if all the harnesses come out 1 side so the wires could all line up in the same direction making it more compact.

Pros: Allows you to install aftermarket radios

Cons: Price Wire harness layout

Pretty much required for the install in my 2008 Corvette. Made it pretty easy, although there's some extra connection that left me a little confused during the install. NOTE: Turn down the volume on the "chime" module before install. It's way too loud.

Pros: Everything works as expected - worth the money for the simplicity

The PAC is a great device and straight forward out of the box with its directions. I took one star because sometimes it can be finicky on first start up. I've had experiences where it goes into programming mode and takes over the ignition (with two different vehicles 03 Tahoe & 04 Suburban). To remedy this, a disconnect of the battery and reconnect fixed it.

Chad from Texico, IL on 2/22/2019

2006 Chevrolet Silverado 2500/3500

Verified customer (What's this?)
Verified employee purchase (What's this?)

Installed in '06 Silverado 2500HD (bose system), with Pioneer AVH-501ex. As described on website, I had to cut some of the support behind the dash to get the unit to fit (especially with the size of the wiring components with the PAC kit). Installation was relatively simple with basic electronic tools and connectors. 2 areas of caution for future installers: (1) instructions are misleading/inaccurate on the mute wire connections. The pioneer has a yellow/white mute wire and the PAC kit has a brown loop mute wire. The instructions say to cut the loop and connect brown to radio mute (yellow/white on my unit). When following those directions, the amp/speakers would not turn on until you turned the OnStar ON, then OFF - then the speakers came to life. Ultimately, I left the yellow/white mute wire capped and re-connected the brown loop - works perfect now. (2) the SWC harness has 2 options - only connect one or the other (NOT BOTH). There's a 2-pin connector and a blue/white wire. You may want to connect the blue/white wire to the other blue/white wires - DON'T! I hooked up the 2-pin connector and left the blue/white wire capped - all SWC buttons work great.

Pros: Retain factory functions & great sound, detailed instructions

Cons: mute wire instructions should be updated, bulky box to fit behind head unit

New life for an old Suburban

Barry from Overland Park on 10/30/2018

2003 Chevrolet Suburban

Verified customer (What's this?)
Verified employee purchase (What's this?)

This made the installation of a Kenwood DNX994S in my 2003 Suburban "plug-n-play". The steering wheel controls worked perfectly, no programming needed. The chime module does work , but it sounds very tinny and cheap. I'm sure I'll get used to it. The wiring harnesses would have been easier to install if one side would have been a little longer. With plugs on all sides of this interface, it would work best being between the radio and the factory plug/harness. I ended up putting this to the right of the new radio behind the dash storage pocket, and it was a challenge plugging everything in with no room for two hands. There may have been more room behind the new radio if I had cut the metal brace out, but I just removed the old radio's plastic supports. My new radio fit, but it only had an inch or so behind it.

Pros: Makes wiring very simple. Retains factory steering wheel controls without extra programming.

Cons: Plug location makes installed unit a little bulky. Chime module sounds cheap.

This was my first time purchasing from Crutchfield and I will tell you that I will not shop anywhere else for Car Audio products again! They had the best customer service I have ever experienced, kind, patient and very knowledgeable. Along with the Wiring Interface, I had purchased a Pioneer Stereo from them earlier, which I recommend. They were happy to give me the discount on the Wiring Package since I had bought the stereo from them in a separate order a couple weeks prior. Upon receiving my equipment, the instructions were very clear and everything was pretty much a plug-and-play interface, with the typical connection of stereo wires (they told me about these awesome threaded wire connectors which you can see in the picture, just strip, insert, and screw together. No soldering or crimping needed!) I was able to keep all features in my 2005 GMC Sierra (steering wheel cntrls. most importantly, chime feature (this is optional which I love, just plug it in if you want to add it), my OnStar, factory Sub, ect... So far I am loving my new radio and taking advantage of every feature (USB, AUX, and BT which my wife really wanted for hands free phone calls). I was recommended this company from my Brother, and I would recommend it to anyone else! Thanks Crutchfield!

Pros: Service, Ease of Assembly, Price, Amount of Inventory Selection

2004 Chevrolet Silverado 2500/3500

Verified employee purchase (What's this?)

This harness works well in my 2004 Chevy 2500hd. This harness did everything that it promised, my on-star, steering wheel controls, and bose audio system to work with my new head unit. One of the connectors going to the box wouldn't connect tightly, and was causing my audio to cut in and out. I fixed that issue with a zip tie. The door chime is kind of annoying. It sounds tinny and cheap. Turning the volume down in it makes it sound a lot better. This harness is a pretty good buy, just be sure to set the dial to the right make of your stereo and make sure the harnesses are all tightly connected.

Pros: Retains on-star, bose audio, door chime, and steering wheel controls. Pretty simple to wire and install.

Cons: Harnesses may not plug in tight enough. Door chime sounds kind of cheap.

An Unfortunate Necessity

Crutchfield customer from Huntsville, AL on 9/14/2018

2005 Chevrolet Silverado 2500/3500

Verified customer (What's this?)
Verified employee purchase (What's this?)

I installed this around 3 years ago with my radio. It worked perfect until around 6 months ago. I was driving one day when my whole dash and radio cut out. No gauges worked, as if it had completely been unplugged. I pulled over, turned the truck off, and tried to turn the truck back on. The truck did not do anything, as if I had not even turned the key. After some reading in forums, I was able to pull the PAC RP5-CM11 out in the parking lot and the truck turned back on. This unit, according to forums where others have had the same issue, is susceptible to shorting out after warranty is up. I contacted the manufacturer and Crutchfield and I am not able to get a free replacement. Unfortunately this is still the only option that provides full use of the steering wheel buttons, so I am forced to buy a new one.

Pros: Works well

Cons: Doesn't work well forever

Verified employee purchase (What's this?)

The chime. Ugh. Crackling, obnoxious, sounds like a blown speaker being over-driven. Steering wheel controls don't work and unit doesn't dim with dash lighting. I have no way of knowing if this is the interface or due to the way it was wired by Crutchfield (I paid for the ready-harness service.) The parking brake interlock on the head unit is also a bit flaky, but again, can't isolate the failure point. Other than maintaining the chimes for doors and seatbelt, I'm not really sure what this item delivered since nothing else works. Unfortunately I have to carve out time to call and talk to someone in order to figure out what the likely culprit is. Until then, two instead of one star is the best I can do.

Pros: Not sure there are any

Cons: Horrific chime, none of the OEM controls work.

steering wheel controls do not work. everything hooked up correctly (not my first stereo install) and triple checked. the unit led lights up when a swc button pressed but doesn't do anything to the new kenwood head unit. also tried programming the buttons all separate and still nothing. seems the factory amp wire needs to share the remote wire for power up. this could be the issue but feel like I'm wasting time fighting something that won't work. Was supposed to be a nice surprise for the wife and it doesn't work. RAP sometimes works and then doesn't as well. most likely crap in a blue box!

Used for install on an 05 Yukon XL with factory Bose amplified speaker system and a JVC R930 BTS radio. Initially looked like a major project to wire and set it up. The instructions had lots of set-up options for changing programming and such. I just hooked up all the wires, plugged in the connectors as indicated and everything, including the steering wheel controls, worked without any additional programming.

I realize that different harnesses will work differently in certain vehicles, but the reviews made it sound like this harness would make "everything" work. In the C6 Corvette the steering controls for audio work, but the phone controls will not. This is confirmed with PAC. Therefore, in the case of the Corvette I rate it as merely functional.

Issues with module causing error messages on vehicle

John from Tonawanda, NY on 7/3/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Issues with Body Control Module on 2004 GM Pontiac Grand Prix. I had 3 error messages from day 1 when I installed the unit. Errors were: Service ABS system, Service Stability Control system, Service Traction Control. Apparently the Body Control Module on this vehicle did not like the electronic pass through of the PAC module. I figured I would give it a few days to adapt. It apparently did but, once or twice a month the gauges (fuel, tack, temp) will completely go dead with the exception of the speedometer. Additionally, the 3 error messages will randomly come up. I am a technician by trade so I know what I'm doing and soldiered all wires to prevent any problems, or so I thought. After 2 years the 3 error messages now will come on every other ignition start. Could this unit be bad from the start? Poor engineering?

Pros: -Makes an Aftermarket stereo work -Retains full functionality of steering wheel controls

Cons: -Intermittent error codes on computer information center for ABS, Stability control. -Gauges sometimes stop working until restarted. -Instructions not clear at times.

Verified employee purchase (What's this?)

The connectors do not stay in the box. They have clips to hold them but they don't do anything. After three tries I got it to work I put the dash together, closed the glove box, and the glove box closing jarred the wires enough to pop back out. Also the wires connections in the connectors are poor. You can barely wiggle a wire and listen to a speaker crackle and fade in and out. And I'm not talking about a spliced wire, which would be my fault. I'm talking about in the wires going to the box.

Pros: When it works it makes the radio work.

Cons: Poor quality, bad wire connections in the connectors, connectors pop out too easy.

This device enabled me to keep all my factory features in my 2003 Silverado 1500HD with 7 speaker Bose, steering wheel controls, rear seat entertainment, OnStar, and door chime. Speaking of the door chime, it is so loud on the factory setting that it distorts the sound, making it sound terrible. I turned it down, and it sounds better, but it is so quiet that it doesn't really grab my attention like a door chime should.

Pros: everything except the door chime

Easy solution to interface my car with a Kenwood

Keith from Columbia, MD on 5/17/2018

2004 Chevrolet Silverado 2500/3500

Verified customer (What's this?)
Verified employee purchase (What's this?)

Great little interface that worked as designed, with a couple of small tweaks for my Kenwood DMX7704S. The chime is only obnoxious because its ships turned to the highest volume level. Use a small screwdriver and set it to the lowest volume first, then work your way up. If you get a repeating chime, turn everything off and reset the chime by unplugging, and replugging the interface cables again. The default setup for my radio used 5 of the 8 steering wheel buttons out of the box after being set for a Kenwood brand head. Had to program 3 buttons. The interface come with instructions to reprogram, easy to do.

Pros: -Allowed me to continue using steering wheel controls and other car features like retained accessory power. -Once the wires are all connected, it's plug and play. -Upgradable firmware if one is necessary -Very well made, solid connections -PAC support via 800 number, very responsive and helpful just like Crutchfield.

The Pac RP5-G11 wiring system made the install a no brainer. I chose to tin and solder the wiring before heat shrinking over connections. Was able to do all this the day before install. Made it as easy as plug and play. I did have one issue with the instructions, they were wrong for the Sony unit I was installing. The selector switch must be set to seven, not eight as in the included chart states. A quick call to the outstanding Crutchfield technical support solved my problem. Tip: Do not use the cell phone already paired to receiver you are trying to troubleshoot. Frequent disconnects to tech advisor will result.

Pros: Worked perfectly with my Silverado steering wheel controls, could also make custom functions and assign to any button.

Cons: Chart for selector switch was wrong, needed to call Crutchfield support to resolve.

Unit works as described, but....

Robert from Columbus, IN on 4/30/2018

2009 Chevrolet Corvette

Verified customer (What's this?)
Verified employee purchase (What's this?)

I bought this PAC RP5-GM11 unit to pair with the new Kenwood head unit that I purchased so I could retain the factory On-Star and steering wheel controls in my 2009 Corvette. The first thing I noticed upon opening the box, is that for the price of the unit it feels very cheap and flimsy. Onto the installation, the instructions leave much to be desired. The wiring table regarding the colors were correct, however after getting everything wired up per the instructions, I was getting no sound out of the speakers. Finally after about 30 minutes, I gave up and called Crutchfield tech support at 6pm on a Friday and they were wonderful. After only a 10 minute conversation, the guy was able to assist and correct the issue. The PAC unit has 2 places for output, one for factory amplified and one for non-amplified and even though my car did not have a factory bose system, it apparently still has a factory amplifier so we had to connect one additional wire to resolve the issue. After hanging up with support, I started to put the receiver into the dash and started having speakers cut in and out like there was a short. Upon investigation, the plastic pigtails of the PAC wiring harness that plug into the unit are very flimsy and do not plug in very securely to the housing, nor do the clips engage. I had to press very hard and firm to make a good connection, and was afraid that I would break the unit, but did not. All controls work, however cheap design.

Pros: -Retained steering Wheel controls -Retained On-Star -Excellent Crutchfield Tech Support

Cons: -Poor/incomplete instructions -Flimsy Design -Flimsy Connectors

Very useful information

Thanks to the website & vehicle selector, I learned that my vehicle's warning chime was routed through the factory stereo and would have been rendered inoperable without an adapter. This package also included the steering wheel control adapter for my vehicle. The website made it easy to select what I wanted.

Pros: Maintained steering wheel stereo controls & warning chime with stereo install; clear information on website

Cons:

Not terrible to install. The wiring diagram was a bit confusing. There was an optional 15" wire diagram on a sheet of paper that i didn't exactly understand. I called and they assured me that it wasn't needed for my 07 Grand Prix. We had to program all of the steering wheel buttons because the factory setting for Pontiac was not right. This was a bit confusing but we did manage to get it set up.

Pros:

Cons: Confusing wiring diagram. Mainly the extra sheet of paper that wasn't needed was the confusing part.

Everything is great except the door chime sound

Verified employee purchase (What's this?)

This harness worked great for my 03 Tahoe. I would have not gotten an aftermarket unit without this. My only con is that the door chime module sounds soooooooo terrible. I really don't understand how they can't make a decent sounding chime. I really don't want to disable it but I am considering it because I can't stand the sound of it every time I get in and out of my car. If anyone knows of a good replacement to this one please let me know!

Pros: Able to use steering wheel controls

Cons: Horrible sounding door chime

Easy install, good instructions. I did have to make an additional wiring change, with the instructions included in the box. The only issue is that when I hit the microphone button on the stereo for OnStar, it shuts the headunit off completely. Volume, source, etc. all work as intended.

This made wanting to change out the factory head unit possible. I would not have done it if I had to lose all of my accessory functions this harness offers.

Pros: Great tool for staying factory usable!

Cons: Some seek and scan functions aren't quite the same, but that may be due to replacement head unit...

The PAC RP-GM11 performs as advertised. However, the product had several installation steps that were not included in the instructions. Ended up calling the guys at Cruthfield who provided the missing info and we were able to finish the installation. I have done several of these types of upgrades over the years for my personal vehicles and for others and and this one was challenging.

Pros:

Cons: Difficult instructions. Some "secret" requirements not well addressed in the instructions.

Great wiring interface package. Was a little intimidating initially but all wires matched up perfectly with new Kenwood radio wiring. Glad I got the more expensive interface as it retained all chimes and steering wheel controls. Well worth the extra cost.

I have a 2004 Silverado 1500 with Bose system. This kit made installing the aftermarket radio a breeze. I was able to lower the chime down to a very low setting (you could also disconnect the small unit too). Every now and then the steering wheel controls will act up (stop working). Overall great kit.

Pros: Made installing an aftermarket radio super easy. You can also keep the annoying chime and lower the volume on it.

Cons: Steering wheel controls acts up every now and then.

Verified employee purchase (What's this?)

I have a 2003 Suburban with OnStar, Bose and steering wheel controls. The hardware itself is brilliant and high quality. No cheap parts or pieces. All of the connectors fit perfectly and are solid. Easy to set up for whatever stereo you are installing with just setting the selector (small phillips screwdriver) on the side. Connect the wiring for the back of the head unit and it works. Only issue that I ran into was there is a wire marked "remote" Since my unit doesn't have a remote I didn't think I needed it. Wrong! This is the "remote turn on" for the power amp. The Crutchfield rep got me fixed up with this in about two minutes. My only gripe would be the chime. It's a bit cheesy sounding. With that being said the sound level is adjustable on it so I just turned it way down. Win/win since all the bongs and alerts get on my nerves anyway. Overall I'm super impressed and pleased with this interface. Well worth the money.

Pros: Quality components Easy setup and installation Good documentation

Cons: Chime is a bit cheesy

On partially drained battery, interface burned out resulting in truck data bus non-functional (i.e. no power windows, no power locks, no bose amps, most of dash gauges non-functional, indicator light on for ABS, etc). When truck was turned off, radio remained on. 10A charger was used to charge battery and not a jump start. Truck is an 05 Chevy Silverado with Diesel motor.

Pros: Product worked as expected for 1.5 years.

Cons: Should have better circuit around CAN bus when part fails so it does not take down the safety related CAN bus operations of ABS, airbags, etc.
