Illustration / Schematic
The RP5-GM51 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN v2 20 and 16 pin
connector radios. Using this interface will retain factory features such as OnStar, vehicle settings, steering wheel controls (SWC),
front and rear park assist and warning chimes when the original radio is removed. The RP5-GM51 also provides data bus driven
outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
1. Please make your vehicle settings selections before removing the factory radio for optimal installation time. Once the radio has been removed,
the vehicle settings which are normally selected through the factory radio can be accessed and changed by downloading and installing the
PAC Vehicle Settings program from http://www.pac-audio.com/rmware/RP/index.html.
2. The Voice button can be set to activate the factory OnStar function when pressed for longer than 1.5 seconds 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 page 2 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, utilize the buttons that have no initial programming or utilize 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 ash 4 times.
5. The LED will ash whenever a SWC button is pressed.
