PAC's RadioPRO5 RP5-GM11 wiring interface enables you to install a new car stereo and retain useful factory functions in your 2000-up GM vehicle. You can upgrade to the higher sound quality of an aftermarket receiver while maintaining your factory-installed OnStar®, factory amplifier, Bluetooth®, safety warning chimes, and the Retained Accessory Power (RAP) if equipped. In some vehicles, you can also retain your factory rear seat entertainment system. If you're installing a navigation receiver, this interface also features the Vehicle Speed Sensor (VSS), parking brake, and reverse connections you need.
Control your new radio
The RadioPRO5 interface retains your factory steering wheel audio controls with your new stereo. You can even reassign the functions of your factory buttons.
Installation note: This interface will not retain the fader controls on vehicles with the factory premium Bose® audio system.
