About the PAC RP4-GM31 Factory Integration Adapter
PAC's RP4-GM31 radio replacement interface lets you replace the factory radio in select 2006-up General Motors vehicles, and still retain your factory warning chimes, and your steering wheel audio controls. With an additional adapter, you can also keep your rear seat entertainment system and rear seat controls. The interface also works with GM's Bose® system, tying your new car stereo into the factory amplifier.
Another plus — the RP4-GM31 adapter eliminates the need for the steering wheel audio control adapter that's usually required for your vehicle, saving you some cash. See Details for a list of compatible car stereos. Warranty: 1 year.
Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this adapter is compatible with your vehicle.
Important Note: This interface does not retain your vehicle's OnStar functionality. You'll need PAC's OS-4 interface to keep that safety feature working with a new car stereo.

More details on the PAC RP4-GM31 Factory Integration Adapter
Overview: The RadioPro4 (RP4-GM31) is a radio replacement and SWC (steering wheel control) interface that comes pre-loaded with amplifier retention and SWC software, navigation based output signals, and firmware that retains all of the vehicle's original safety and convenience features when replacing the factory radio with an aftermarket head unit.
Functionality: The RP4-GM31 interface allows the replacement of a factory radio in select GM vehicles with the CAN-bus system. Using this interface will retain factory features such as steering wheel controls (SWC), rear seat entertainment (RSE), rear seat control (RSC), the factory Bose amplifier, and Warning Chimes whenever the original radio is removed. In order to retain rear seat entertainment (RSE), you will also need the PAC GMRVD GM Rear Seat Video Retention Adapter (127GMRVD, sold separately). The RP4-GM31 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger, and parking brake.
Note: The RadioPro4 (RP4-GM31) does not retain OnStar. For OnStar retention, please use the PAC OS-4 (127OS4, sold separately). If your vehicle is equipped with a digital amplifier, you will lose fading capabilities when the new aftermarket radio is installed.
Vehicle Compatibility: The RadioPro4 (RP4-GM31) is compatible with select 2006-up GM vehicles with databus radios. Compatible vehicles as of 7/13/2012 include:
Vehicle Specific Notes: 2012 Avalanche, Sierra, Silverado, Suburban, Tahoe, and Yukon vehicles equipped with a navigation radio are not compatible. Chevrolet Express vans & GMC Savannah vans equipped with diesel engines are not compatible.
Note: Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible. Visit www.pac-audio.com for the most up to date information.
Radio Select Switch: The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the interface into the vehicle.

this adapter was so easy to wire in, only took a few minutes and I am far from a pro. Door chimes, blinker and steering wheel controls still work great!! Good product, Good buy!
