Illustration / Schematic
The RP5-GM32 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) and the BOSE amplifier when the original radio is removed. The RP5-GM32 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.
