PAC RP5-GM61 User Manual

RP5-GM61
Introduction and Features
The RP5-GM61 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN v2, 20-pin and
16-pin connector radios. Using this interface will retain factory features such as BOSE, OnStar, vehicle settings, steering wheel
controls (SWC), front and rear park assist and warning chimes when the original radio is removed. The RP5-GM61 also provides data
bus driven outputs such as retained accessory power (RAP), vehicle speed (VSS), illumination, reverse trigger and parking brake.
Important Notes
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 RadioPRO PC Application from http://www.pac-audio.com/firmware.
2. Before removing your factory radio, please review the following settings as these will not be retained once the factory radio is removed:
• Ambient Lighting Control
• Teen Driver Feature
• Valet Mode
• Rear Park Assist Symbols displayed on Reverse Camera Image
3. When you plug in the module for the first time, it must go through an initialization process that takes up to 12 seconds. Make sure you have
the vehicle running diring this process.
4. The radio select dip-switchs 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).
5. The Voice button can be set to activate the factory OnStar function by using the RadioPRO PC Application. By default, this button is
re-programed to control the aftermarket radios voice function.
6. For retaining OnStar, you must add on an additional RPA-SPK Chime speaker if you are using an aftermarket amplifier on Mids & Highs that
can be purchased seperatly.
7. 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 flash 4 times.
• Chevrolet Malibu will require SWC re-mapping. By default volume up / down and track up / down are reversed.
8. Language: In some vehicles the Lauguage setting is controled over MOST. Please make sure that you adjust this accordlingly before removing
the radio as this will not show up in most cases after your install.
9. Please reference the vehicles RPO CODE sticker normally located in the vehicles glove box or the underside of the spare tire cover.
