PAC RP5-GM11 Radio Replacement Interface Compatible with Select 2000-2013 GM Vehicles, Retains OnStar, Steering Wheel Controls & Bose Factory Amplifier, Plug & Play Car Stereo Wiring Harness

Used for my 03 Escalade Put in an alpine Ilx-w670 head unit. Factory sub works fine it was kind of odd the fade function doesn’t work if I fade the volume to the rear speakers it goes silent but if I center the fade all speakers work and sound great. Also I had to do some searching online to make the steering wheel controls work because for what ever reason I had to change the pin setting to universal instead of alpine specific. Anyways it works great.

I have just installed this device in my 2005 Chevy Tahoe. So far this has worked excellent. Fairly simple to wire up, makes the steering wheel controls work perfectly. Has the leads for the reverse gear for a backup camera already(this wire was not the same color as the wire out of my new head unit, it was labeled correctly but different color). Will allow you to retain the rear seat controls, and the audio for the factory DVD player. I set the chime to volume 3 and it sounds good. This is somewhat bulky and does take some work to push all of this into the dash of the Tahoe. My system has factory Bose amp, and for some reason in my mind when I was connecting all the wires I did not connect the amp lead wire out of the head unit. I assumed that since it was a factory install it wouldn't require that connection. When I connected this I had all functions, but no audio. One quick call to PAC fixed me up. They knew exactly what I had done, and was about a 1 minute conversation with the tech guy. Would definitely purchase this again.

Easy to install works as it should

Amazon fitment does not say that this is a fit for my 2004 GMC Sierra 1500 but identifies another product only. Long story short, that product is not the right fitment, but this product is the correct one for my truck. The nice thing about this product is that you only need to worry about matching and soldering wires related to your new car audio system. When you open the package, there is a QR code linking the product installation instructions. In the instructions, it will show you where all the headers are connected and defines all the colored wires. The reason why I dinged a star is because the documentation for configuring the SWC is a bit lacking. The harness wasn't difficult to setup and I was able to install my car audio system.

i have used them in the past ,,even though i did not need it and returned ,radio came with all equipment needed ,but if you need they do work well with gm cars and trucks

I returned/exchanged the first RP5-GM11 as it seemed to have loose internal connections. The issue I want to make others aware of is the speaker hiss I experienced with both. Both were latest versions with latest firmware. The hiss was loud enough to clearly hear while driving along in a Hummer H2 with the radio volume turned down all the way. The hiss is present whether the engine is running or not. The hiss was not engine whine. My vehicle: 2003 Hummer H2, bose sound system - OEM 6 disc head unit, bose speakers with OEM center console subwoofer, and "luxury" version of the bose amp. The LUX amp is the digital one, and I can now advise that you should really know in advance which one you have before choosing an interface like this. Google lux vs premium bose amp. See attached photo (posted by another installer) We are not talking about whether or not your vehicle is a "luxury" class model or not. I upgraded my head unit to a Pioneer AVIC8200NEX. Whether or not my new head unit wiring harness was even plugged into the RP5-GM11 module, and no matter what audio source was selected even if fully connected, I expereinced a low level hiss coming from all speakers. All my connections were double checked, soldered, and all grounds were inspected and fine. The hiss only went away when power was removed from the RP5 unit. That only happened when I chose to "power off" the head unit completely. PacAudio was responsive when I contacted them. We verified I had made connections properly. They advised me that they tested their unit with "all trim levels" and this was the first they heard of this. They suggested I bypass the amp. Why buy this harness if I am going to bypass my amp? I didn't want to spend the time or money on a new amp, or speakers either, hence the reason I bought their product. I just wanted to integrate a new head unit. For that matter, most head units can't put out the same power as the LUX amp, and then one has to be concerned about matching OEM speaker impedence with the radio's specs so as not to damage it. In bypassing the amp I wouild have lost the two rear-most speakers (each have 14ohm impedance) and the OEM subwoofer as well. A search of the internet, however, revealed others with the hiss issue. Enter the GMOS-04 unit by Metra / Axxess. I installed the GMOS (which I didn't buy at first as the RP5-GM11 seemed to have more favorable reviews). The GMOS has an adjustable gain. There is no adjustment for this on the RP5-GM11. What makes the GMOS better? 1) That adjustable gain screw adjustment. Again, both with and without the new head unit connected to the GMOS just like the RP5-GM11, with the gain turned all the way up, I heard the speaker hiss. Back down the gain just a little and the hiss was gone. Amen. As for volume, even with the gain turned down more from where I set it, the sound was still louder than before with the OEM head unit. I lost nothing. 2) On-Star volume can be controlled directly from steering wheel volume control - with RP5-GM11, you had to pick from one of a few preset levels and have to access the module to do so. 3) The GMOS is firmware upgradeable via a common micro USB cable - with RP5-GM11, you have to get some proprietary cable from them. Why should we have to spend even more to upgrade firmware? While the RP5-GM11 may not cause hiss issues for GM owners with the "premium" non-lux amps, I would encourage anyone with speaker hiss (not engine whine) to try this GMOS over the Pac Audio product to solve the hiss issues. By the way, the GMOS was not any more complicated to install than the RP5-GM11 and I actually prefer how much better it performs.

Excellent. Retains steering wheel controls and all stock factory functions including Bose.

Mind you this is short term I just installed the item but wow everything was so good about it. The instructions were extremely clear and good. The steering wheel controls were retained as I wanted. The sub also works without issue. I left the chime unplugged as I don't enjoy annoying sounds for reasons. Onstar also works even though I wish it didn't. Very well packaged good instructions and quality materials. The price is high but it comes with everything you will need. I use wagos for ease of instal and troubleshooting. I have wired a few radios with them and can definitely recommend.

Great replacement part and works well.

Bon produit mais délai de livraison trouve important à mon goût

Se recibió en tiempo y forma y funciona perfectamente

I purchased this along with a Metra dash install kit, and an Android Double DIN stereo for an audio upgrade in my 2003 Chevy Avalanche LT Z71. I am an avid audiophile and wanted something that wouldn't break the bank, but would hopefully deliver decent audio quality and would keep factory options. the RP5-GM11 harness & module kit was the answer! I have done over a dozen personal car audio installations, most of them with far fewer options in the vehicle, and this one was by far the easiest! The kit comes with literally everything you need. I had the entire harness built, soldered and taped up ready to install in 45 minutes. I used this system to retain the Steering Wheel Controls, Rear-Seat Audio Controls, Factory Bose Speakers (6), Subwoofer & Amplifier, and to convert the antenna cable to GM spec. The directions are very straight forward and make it easy for even beginners to wire and install this system correctly. I set the SWC on the module to 7, for 'other brands' and to my satisfaction the single wire output from the SWC worked for my system! I thought I was going to have splice the wires from the 3.5mm jack. Entire install from beginning to finish was less than two hours, including removing the stock stereo, and finishing the new install to be set in the dash correctly. Very impressed with another great product from PAC!
