Our take on the PAC RP5-GM11 Wiring Interface

by Dave Delamere
iSimple

Keep your factory features

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.

Control your new radio

The RadioPRO5 interface retains your factory steering wheel audio controls with your new stereo. You can even reassign the functions of your factory buttons.

Installation note: This interface will not retain the fader controls on vehicles with the factory premium Bose® audio system.

Feature

GM Class II (24-pin/12-pin) Radio Replacement Interface: The PAC RP5-GM11 radio replacement interface allows the replacement of your vehicle's factory radio with an upgraded aftermarket head unit in select GM vehicles. The RP5-GM11 has been engineered to interface seamlessly with your vehicle's computer data bus system (Class II) and retain important safety and convenience features. This all-in-one radio replacement interface offers OnStar retention, amplifier retention, built-in SWC, navigation based output signals, and other features that save time during installation.

  • Convenience Features: The PAC RP5-GM11 radio replacement interface retains a variety of convenience features when replacing your vehicle's factory radio with an aftermarket head unit. You'll continue to be able to use your vehicle's factory OnStar system with turn-by-turn voice prompts and volume adjustments. Your vehicle's warning chimes (w/ volume adjustment) and retained accessory power output (RAP) will remain completely functional. RAP allows the ignition power source of many GM vehicles to keep the radio on until one of the doors is opened.
  • Amplified & Non-Amplified Systems: The PAC RP5-GM11 is compatible with amplified and non-amplified factory audio systems. Its compatible with both Bose and Premium Bose audio systems. The unit does not support fading for Premium Bose systems.
  • Factory Entertainment Features: The RP5-GM11 retains several factory entertainment features; including Bluetooth (2009+ vehicles), rear seat entertainment (RSE), rear seat audio controls, and dual zone functionality. In order to retain factory rear seat entertainment, your aftermarket head unit must be fitted with a rear-panel AUX or AV input.
  • Navigation Outputs: The PAC radio replacement interface also provides a VSS (vehicle speed sense), Parking Brake, and a Reverse Gear output to make installing an aftermarket navigation head unit simpler and less time consuming. In addition, the interface retains your vehicle's back-up sensors and park assist feature.

Built-in SWC: The interface comes pre-programmed for all of the vehicle's factory SWC functions and does not require programming, unless you wish to re-assign the SWC functions to different buttons. The SWC functions can be easily programmed; see control settings and functions in owner's manual. The interface retains programming even if your vehicle's battery is disconnected.

Note: The SWC harness contains a Blue/Yellow wire and a 3.5mm connector. You will only use one of the connectors, based on your type of aftermarket radio. The Blue/Yellow wire supports Kenwood, Newer JVC, OEM and Blaupunkt radios. The 3.5mm jack supports Alpine, Older JVC, Clarion, Pioneer, Sony, and Dual radios. Not compatible with Soundstream head units.

Vehicle Compatibility: The PAC RP5-GM11 is compatible with select 2000-up GM vehicles with Class II (24-pin/12-pin) data bus systems. Compatible vehicles as of 2/18/2014 include:

Good Adaptor

Written By Jeff, ABQ, NM on Tuesday, September 16, 2014
Crutchfield Customer Review (What's this?)
 
A very good adapter but not for those with limited electrical background. You will have to marry two pigtails and I found getting and maintaining a good connection very challenging. I recommend soldering and shrink wrapping the connections if you have the option. I tried pinch connectors and ended up having to switch to wire nuts. I'm sure the experienced among you are chuckling but this is not a "plug and play" kind of thing so be prepared. In hindsight I would have taken it to an installer. The unit itself works perfectly.

easy to install

Written By Brian d., Wellington, fl on Thursday, September 11, 2014
Crutchfield Customer Review (What's this?)
 
I bought this for my 2007 Chevy Silverado classic. I have a Bose surround system installed. This was very easy and plugged into all of the components in the truck. No cutting or crimping required. When I switch to switch it out the notification buzzer was very loud and annoying, now I can barely hear it makes it very simple and easy. Would buy again!
Pros:
full picture directions, programmable for all steering wheel functions, easy to install, no crimping required, quiet buzzer.
Cons:
a little large and may be difficult to fit in the compartment with deep units. Shallow ones no problem.

Retaining the factory amp with a new deck

Written By Garden Sausage, Phoenix, Az on Sunday, August 24, 2014
Crutchfield Customer Review (What's this?)
 
This product is quite easy to install and comprehend. Directions are definitely needed to program the wheel controls. After time I got this wired in and working great withing about 30 min. Even with some issues I would say if you are not to the point of running all new speakers and amps but just need a deck this is a great choice.
Pros:
Allows you to change out your broken deck and retain your factory amps and steering wheel controls.
Cons:
Steer wheel programming isn't perfect but it got me close enough to how the buttons on the wheel are labeled. Directions on the wheel programming can be confusing. Trial and error is needed to finally figure out what you need to do to get it right. Unit is kind of big so it is snug behind the deck. Heads Up no longer displays the station ID or anything related to the radio. Could be my deck choice but I saw no option for HUD wire-ups.

Quick to Setup Worked Great

Written By BryanM, Columbia, MD on Friday, August 15, 2014
Crutchfield Customer Review (What's this?)
 
The OnStar, door chimes and factory amp in my 2001 Chevy Impala made me hesitate to buy a new head unit. I really wanted auxiliary input and bluetooth, so I found this product to help the install. I was definitely impressed with how easy it was to install. When installing a custom head unit in an impala however, make sure you choose the input without factory amp. Bypassing the amp is the only way to get quality sound from a third party head unit. The only problem I have is that the steering wheel control diagram was not accurate. I have to manually configure the steering wheel controls for my Kenwood head unit.
Pros:
Quick and painless install.

PAC RP5-GM11 Factory Integration Adapter

Written By Blake, Arkansas on Friday, August 08, 2014
Crutchfield Customer Review (What's this?)
 
Like the unit, works well with the steering wheel controls. Fairly easy to install, do not like the way the power connections are made. When installing all the excess wire and the unit in the dash, the cheap heat shrink on the power wire tore, shorted to ground and killed the unit.
Pros:
Unit works well with the steering wheel controls.
Cons:
The cheap heat shrink on the power wire tore, shorted to ground and killed the unit. Kind of hard stuffing the unit and extra wiring in the dash. Becareful when installing.

Great Adapter..

Written By Rudolph, Houston, Tx on Monday, July 21, 2014
Crutchfield Customer Review (What's this?)
 
Adapter does as it advertises. With little previous history needing these adapters-I was a little worried about the install. It does install similar to a basic harness. Allowed me to keep my steering wheel controls in my 03 Sierra- well all those except the mute button. Program changes between sources, seek changes track or station, volume works. Wish I could mute with my steering wheel on the fly (may be a way to program manually-honestly havent re-read the manual to try this) but it does not work from factory with pre-programmed setting. The unit is quite bulky as it has 3-4 wiring connections on the box as well as a chime module which all have to fit in the dash. Luckily, this was not an issue in my sierra as I could push it behind the dash along the left side almost behind the instrument cluster. Be careful not to pinch the wires as you push the CD player in your dash. All in all, does what it says, but wish the mute button was pre-programmed by PAC.
Pros:
Fairly ease of install. Does what it says..mostly. Provides both a mic input and wire for SWC connections to fit your needs across multiple radios.
Cons:
Wasn't pre-programmed for mute button..which I attribute to being such a generic adapter for cross platform application. Quite alot of wires to fit in the dash which is an eye sore if you don't wrap to clean them up.

Crutchfield Support Second to None

Written By D.H.,, N.J. on Wednesday, July 16, 2014
Crutchfield Customer Review (What's this?)
 
Like some of the other reviewers this is more Kudos for Crutchfield Support and staff. Received Pioneer FH-X700BT as a fathers day gift for my 2006 2500hd silverado. Unfortunately my kids didn't purchase it from Crutchfield other wise the PAC-RP5 would have been about half the cost but they did tell me to go to Crutchfield to get everything I needed to install it. Went on on their website and plugged in all the information about my vehicle and it returned with a list of everything I needed! GREAT website! Still not sure if the PAC-RP5 was the one I needed to keep all the factory controls for the Bose, steering wheel controls and On-Star , I followed up with a phone call. Spoke with a product advisor who pleasantly and knowledgeably answered all of my questions and was able to process my order while I had it up on my computer screen. Received everything (PAC-RP5-GM11, GMK-422 In-dash Receiver Kit and Metra 40-GM10 Antenna Adapter) a few days later. With Crutchfield and the product instructions it was a pretty straight forward install. Got everything up and running in the evening.next morning nothing worked. Removed it checked the wiring. Spoke with tech support at Crutchfield and he set me straight on the orange/white wire and red acc wire. Made the correct changes and I was back in business but no alert chimes. Spoke with tech support again, bad CMX module(chime), had to send a complete PAC unit. A few days later replaced the CMX module and everything thing is up and running. Working flawlessly.
Pros:
Great stereo! everything that I needed to do the install Crutchfield had and the expertise and knowledge to make my life easier.
Cons:
The chime module sounds cheap compared to the factory tone but it works as advertised.

RP5-GM11

Written By Jon, Lexington, NC on Wednesday, July 09, 2014
Crutchfield Customer Review (What's this?)
 
This interface did mostly what I needed it to. The installer couldn't get all my steering wheel controls to work properly. I have a 2003 Chevy Silverado SS with the Bose package. It does connect my Pioneer radio to my Bose system and pushes it nicely. I was a little freaked out that my "dinger" for my keys changed tones. I suppose that is built into the interface? Overall I was a little disappointed not all the buttons on my steering wheel work as I had intended.
Pros:
Connects radio to Bose System. Got a discount when purchased as package through Crutchfield.
Cons:
Not all the steering wheel controls work.

This device let me keep my sound entertainment, on-star, and sreering wheel controls in my 06 Suburban. Has been working very well since i installed it.
Pros:
A lot less than the price given to me at Car Toys. Easy to hook up, even for someone who hasnt done it before which wasnt my case but decided to just say that it was.
Cons:
Since my stereo is just a cd player and not an in-dash or flip out, i have to plug the auxilary from the front and the chime sounds weak, nothing like GM's chime but it does the job. Cant get everything always.

Looks like a pain to hook up but was pretty easy to install, Some times have to push the buttons twice to get volume to change, there is a little bit of a delay when you push button and radio finally adjusts, the chime is pretty loud and is annoying at times thinking of disconnecting it or covering it up with something to quite it down
Pros:
Keeps all steering wheel controls, easy to hook up, has door chime
Cons:
Door chime sound is annoying at times, lag between pushing buttons and adjusting

This adapter works great in my Yukon. The most time consuming thing was to splice together the wiring.
Pros:
Works great, easy install works seamlessly with the JVC KW-R710.
Cons:
The chime is a bit too loud, but duct tape solved that. Also the steering wheel control(SWC) was confusing initially but worked out great in the end.

Does what you need it too, and you get crutch field support on the ins

Written By Matt, San Diego CA on Sunday, April 27, 2014
Crutchfield Customer Review (What's this?)
 
Item does exactly what you need to which is retain door chimes, steering wheel controls, and Rear Seat Entertainment features of your mid-2000s chevy (in my case the 2005 Chevy Uplander). Instructions were at times a bit general - for instance the purple wire is for the left rear speaker which would be straightforward except there are 2 purple wires on the harness so I had to do trial and error to figure out which one did what (the other identical purple wire was for steering wheel controls I think). Also the unit has two plugs one for amplified systems one for un-amplified but the instructions on where to plug everything in were drawn only one way without a clear explanation. Led to some confusion on my end before I called for CF support and made the simple switch. My only real complaints are the chime module is pretty lame, it says for best results get it as far away from the radio as possible and pointed straight down, I did this but it still seems a bit inconsistent, like it works most of the time but every once in a while it cuts off abruptly and the sound is pretty bad (not quiet or anything, just unpleasant and gritty like it's coming through the worst speaker of all time or something). Lastly it CAN retain RSE not just in the headphones which is AWESOME because I want to hear what the kids are watching on long trips BUT you need an adapter it doesn't have and that's kind of annoying to me. Please include an RCA female to 1/8in cable and save peeps a trip :)
Pros:
Makes switching the factory stereo in your unnecessarily complicated mid-2000s chevy possible without losing any features (on star, Rear Seat Entertainment, steering wheel stereo controls, and door chimes)
Cons:
Ridiculous expensive - would cost more than most stereos which is just insanity but I mostly blame chevy for making it complicated by integrating everything. Instructions aren't clear in a few places - Don't include 2 wires of the same color that do different things without any indication at all which 1 to use for what. The door chime module is pretty crappy though functional. Include an RCA female to 1/8in male adaptor or RCA extension if decks have RCA aux input so RSE can be fully retained

Shoddy build quality

Written By Evan, PIerre SD on Thursday, April 24, 2014
Crutchfield Customer Review (What's this?)
 
I installed one of these in a an 05 Avalanche with Bose right away I had problems. The conections into the "brain" (the blue box thing that everything plugs in to) didnt snap securely, any bump to the wiring would cause them to come loose. Even when I had all the connections in and plugged securely I got really loud alternator interference even at idle and the drivers door speaker was hit and miss whether it would work or not. So I called Crutchfield and they promptly sent me a new unit. So I tear apart my dash again, assuming this one would work perfect. Nope. Very similar issues with the new unit. So I call Crutchfield again. They are now sending me the a Metra unit that does the same things. Hopefully Metra hired someone that knows how to solder, PAC sure didn't
Pros:
It was fairly easy to hook up. One unit does everything, you don't need a separate unit to retain steering wheel controls.
Cons:
Very badly built. Like Yugo badly built, Like leaning tower of Pisa badly built, Like Tacoma Narrows Bridge badly built, Like a Chauchat badly built, Like Apple iii Badly built, If you don't know what some of those things are, take my word for it they were all really bad.

Works Great with my 2004 Chevy Silverado

Written By Sheldon, Northern California on Sunday, March 30, 2014
Crutchfield Customer Review (What's this?)
 
First unit had some issues and was bad out of the box. After calling crutchfield tech support, they quickly sent another one to me (3 days) and this time the unit worked flawlessly. Easy to follow instructions, and no problems connecting to stock wiring harness and my new pioneer deck. All steering wheel controls work with no probs, warning chimes, on star, and rear controls all work. Just set the small dial on the unit to match the manufacturer of your stereo and presto! It works. Also, you get a great deal when buying this with a new stereo. Crutchfield is great, any questions at all, they are there to help. Can't see why anyone would go anywhere else, they have great products and prices and most of all, people that can help and KNOW what they are doing. Do your homework, you will need a unit like this if you want anything else in your Chevy to work besides the speakers!
Pros:
Great instructions, easy to set up, and they give you almost too much wire on the harnesses!
Cons:
The piezo for the chimes is a little cheesy sounding but works

Certainly needed this to make the steering wheel controls and ONSTAR function with the radio. Works perfectly
Pros:
Works like described.
Cons:
Adds almost 100.00 bucks to your installation costs.

Finally a harness that works for the Corvette!

Written By Alex, Davenport, IA on Sunday, March 23, 2014
Crutchfield Customer Review (What's this?)
 
I have been looking for a harness that works for the C6 Corvette and after some research online, found that the Metra GMOS-04 works but does not retain the active handling and ABS system chimes. Several people online reported that the PAC RP5-GM11 keeps both the door chimes and the warning chimes such as ABS, active handling, low tire, etc. so I decided to give this a try. Ordered from Crutchfield and could not be more pleased with their customer service. I had two issues with the installation: (1) The unit is quite large and does not easily fit in the Corvette's dash unless the wires are neatly bundled together. I ended up cutting the radio harness and the PAC's harness about 2-3" shorter so the wires were not as long. (2) The steering wheel controls at first did not work. Not sure if this is Corvette specific, but disconnecting the battery for 30 minutes and then reconnecting the battery allowed the steering wheel controls to work. After I got everything working, I was pleased with how this harness worked and the sound quality is excellent! Even though it converts speaker level to line level (to feed your factory or Bose amp) the sound is great with no hiss or background noise like the stock radio. Overall, a great harness, and kudos to Crutchfield technical support for helping me get this working. If you own a 05-13 C6 Corvette, this is the harness to get!
Pros:
Keeps the factory ABS, Active Handling, and Low Tire Pressure chimes.
Cons:
Wires are a bit long requiring careful placement of the unit in Corvette applications.

Plug and play perfect......by far the best harness for your gm truck.
Pros:
Steering controls harness come with this package...you don't have to buy another harness to use your steering wheel controls..plus the wires are the perfect length so your not trying to stuff a bunch of wires into your dash...very very easy to program
Cons:
The aftermarket chimes are very very annoying...the worst sound on the planet....lololol...so buckle your seat belt ASAP

Low Volume in Rear of Vehicle

Written By David, Fremont, NC on Sunday, March 09, 2014
Crutchfield Customer Review (What's this?)
 
I soldered all my connections and used shrink wrap and once the install of complete i had sound issues in my 2005 Avalanche. The sound was fine from the front speakers , however the sound in the rear speakers was so low you couldn't hear it from the front. Adjust all the settings to no avail, called PAC support and they had no solution other than to change the port for the wiring harness on the RP5 to the Non-Amplified Factory sound port and this gave me sound in the front and rear but there was static noise in the radio. The static seem to be caused from using the non amplified port that amplified the signal and then sent this amplified signal to the factory Bose amp thus causing the static noise. I confirmed i have a Bose amp by the UQ7 code in the glove box and by disassembling the center console for visual verification. I then replaced the RP5 on the premiss it was defective and the new unit functioned the same way. Lost many hours pulling the reinstalling the Kenwood DNX890HD. I finally corrected all this by removing the RP5 and installing the Metra GMOS-04 in my Avalanche ( Onstar,Bose Sound system & Navigation ) despite the fact Crutchfield couldn't confirm it to be compatible with my Avalanche due to it having factory Navigation but it worked flawlessly and added the Pac SWI-RC which i didn't care for either as you have to tap into the lime green wire under the steering column for it to work.
Pros:
Small size no programming required
Cons:
Sounds almost no existent in back of truck and had static noise in audio and at a volume setting of 0.

Nice harness

Written By Manh, Charlotte NC on Thursday, March 06, 2014
 
I bought this harness to install on a 2005 Chevrolet Suburban with Bose and OnStar system and steering wheel controls. everything came with the harness as promised and installed pretty easy. there are only a couple of complaints that I have. the first is the steering wheel control. the harness has a one wire system or a mini din plug. my stereo has a two wire hookup. so I only get volume up and down, secondly when I installed my stereo I lost my factory TPMS. I am working with tech support on that but so far no resolution. Everything else works great! OnStar, Rear entertainment, rear DVD (there is a little noise until the DVD starts but not really a big deal) the door chimes, etc... on another note, the space is REALLY cramped. you will have to get creative on shoehorning the harness and box in there. I would highly recommend this system!
Pros:
easy to install, great directions, everything works as promised
Cons:
lots of cables, tight fit, TPMS stops working

Makes install easy

Written By Chris, Indiana on Thursday, March 06, 2014
Crutchfield Customer Review (What's this?)
 
I ordered this as needed to maintain my chimes and warnings in my 2005 Chevrolet Silverado 2500HD Duramax. It made the install so much easier. I was able to make all of the connections from the wiring harness of the stereo unit (Soundstream VR-652NB DVD Receiver ) while at the kitchen table. The stock wiring harness connected right up and I was able to install the receiver very easily. I do think that the attached chime module could have been better. It sounds as though it is dying not clear and crisp but it doesn't bother me that much. Also since I was connecting to a soundstream, I had to test and retest the different presets to find the right one for my receiver so that the steering wheel controls would work. They don't work perfectly but the volume and source buttons work great. By the way the setting I had to use on my truck was the number 3 position.
Pros:
Makes install a breeze and maintains chimes and SWC.
Cons:
Chime warning a bit sick sounding and the fact that I had to hunt for the correct setting for my receiver unit.

PAC RP5-GM11 Wiring Interface

Written By Potts, Corinth, MS on Friday, February 28, 2014
 
Product will not allow you to keep the DVD entertainment center in the back of a 2005 Tahoe. It will allow it to play the sound but the people in the front can't listen to the stereo. They have to listen to whatever is playing on the screen.
Pros:
Full function steering wheel control
Cons:
Does not allow the driver to listen to radio while the DVD player is on.
Crutchfield response on Tuesday, March 11, 2014
To fix this problem, viewers in the rear seat need the wireless IR headphones from the dealer (GM part #20830572). If those are used, you won't have to switch the stereo to the aux input (the rear seat system) and the front passengers can listen to a different source. We reached out to the customer to let him know this option is available.
