RP5-GM41
& Steering Wheel Control Interface
with OnStar Retention for General Motors Vehicles
Pacific Accessory Corporation
Important Notes
Illustration / Schematic
The RP5-GM41 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN
v2 44-pin connector radios. Using this interface will retain factory features such as OnStar, Bluetooth, steering wheel
controls (SWC), and warning chimes 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-GM41
also provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination,
reverse trigger and parking brake.
1.
Once the radio has been removed, the vehicle settings which are normally selected through the factory radio can be accessed by downloading
and installing the PAC Vehicle Settings program (for windows PC)
.
Please make
your vehicle settings selections before removing the factory
radio for optimal installation time.
2.
The Answer/Voice & End/Mute buttons can be set to do the factory OnStar functions or given the ability to control the aftermarket radio. This
option can be found in the PAC Vehicle Settings program mentioned above in note one. The default setting for these buttons is to control the
factory OnStar. If these buttons are set to control the aftermarket radio, OnStar can still be accessed by using the mirror controls.
3.
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 below for setting chart).
4.
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 the short press long press dual command functionality. 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 4 times.
5.
The LED will flash whenever a SWC button is pressed.
