PAC RP4-GM31 Factory Integration Adapter

Features

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.

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.

Wiring Connection Chart: The included wiring harness features the following hardwire connections.

SWC Compatible: 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 below.  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, Valor, and Dual radios. Not compatible with Soundstream head units.
