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. Use of this
interface also allows you to program two radio functions to each SWC button by using short press long press dual
command functionality. 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 or utilize short press long press dual command functionality. The SWC can always be
restored to default settings by following the procedure outlined on page 3.
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.
