The PAC RP3-GM11 Radio Replacement Interface for Select GM Vehicles without OnStar is for GM vehicles with Class II data-bus and 24-pin harness. It has a high-current 10A accessory output as well as data-controlled outputs for connect to your navigation radio—speed, reverse, and E-brake status output wires. It retains the factory-installed amplifier, if so equipped. The RP3-GM11 has a data-controlled R.A.P. accessory output, a plug-in connection for steering wheel control SWI-RC or SWI-X and keeps vehicle data-bus intact for service. The chime volume is adjustable with four levels and off. The interface can be quickly updated if needed from the PAC website using PAC-UP USB adapter. Includes RadioPro3 module, plug & play vehicle connection harness & instruction manual.

Worked in my 2004 trailblazer, restored my chimes and no more battery drain from the door opening and not shutting off the radio. It fixed that issue!

Works as intended. Instructions are vague.

Does what it is supposed to, but the illumination wire was in the wrong location for my 03 impala, easy enough to pull the pin and replace it in the correct position, but the listing does say it's a direct fit product for my vehicle, so I had to knock a start off. Oh the chime sound is cheap too, but it isn't unbearable and that is admittedly subjective.

Works great! Replaced it with the previous version, C2R-GM24 cause the buzzer stopped working and this version works great! They've made it easier with all the cables now as i had to bridge cables before, now its all done for you. And now you can control the buzzer volume.

Got this for my 05 silverado, no bose system. Very easy to install, all plug and play. The chime tone isnt the same but it didnt bother me at all, and is also adjustable. I highly recommend. My truck is the base model and doesnt have steering wheel controls but that wasnt a problem.

Works great. After minimal wiring, everything snapped right in place. I recommend to sync the unit after installation. Make sure the ignition is off and the driver door is open. Install the unit to the stereo and vehicle. Close the door and turn the ignition to the ACC position. Wait 30 seconds. Turn off the ignition and open the door. That's it. you should be good to go from this point forward.I've attempted the Metra and Scosche adapters in my 2005 Chevy Colorado with poor results. The Scocshe worked for a few years and slowly started to fail and eventually quit working altogether. I replace the Scosche with the same model and the radio still would not come on. The Metra worked sometimes. However, I had to constantly sync the system to get the radio to come on.
