PAC RP3-GM12 Radio Pro3 Rentention Module

The RP3-GM12 interface allows the replacement of a factory radio in select General Motors vehicles with Class II radios.
Using this interface will retain factory features such as Warning Chimes when the original radio is removed.
The RP3-GM12 provides data bus driven outputs such as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
The RP3-GM12 also provides a secondary output for adding an optional PAC Steering Wheel Control (SWC) retention interface
