Illustration / Schematic

The RP5-GM31 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN 

radios.  Using this interface will retain factory features such as OnStar, steering wheel controls (SWC), warning chimes, 

Rear Seat Controls (RSC), factory XM Radio and the BOSE amplifier when the original radio is removed.  The RP5-

GM31 also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), 

illumination, reverse trigger and parking brake.

1. 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 (see next page for setting chart).

2. The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require programming unless 

you wish to re-assign the SWC functions to different buttons.  The SWC can always be restored to default settings by pressing 

and releasing the program button on the side of the interface once and waiting 7 seconds for the LED to flash 3 times.

3. RSC buttons that are identical to the SWC will mimic the SWC one for one.
4. The LED will flash whenever a SWC button is pressed.
