About: PAC GM1A-RST Replacement Interface with Chimes, SWC and Factory Amplifier Retention for Select GM Vehicles

RadioPRO Advanced has been engineered to save you time and seamlessly integrate into a vehicle's databus system to retain features such as OnStar, steering wheel controls, factory amplifier, audio fade, rear-seat entertainment system, and warning chimes. RadioPRO Advanced also improves sound quality of warning chimes by playing them through the sound system, or through a provided speaker, while direct USB connection makes product setting adjustments and firmware updates quick and easy. It also saves you time on the installation with a streamlined harness design, smaller housing, and easier adjustment of chimes and factory amplifier gain.

The GM1A-RST interface allows the replacement of a factory radio in select General Motors vehicles with the Class II Data-Bus. Using this interface will retain factory features such as Warning Chimes, Bose Amplifier, Steering Wheel Controls (SWC), Rear Seat Entertainment (RSE), and Rear Seat Controls (RSC) when the original radio is removed. The GM1A-RST provides data bus driven outputs such as retained accessory power (RAP), vehicle speed signal (VSS), illumination, reverse trigger and parking brake. You can also add multiple camera inputs to your aftermarket radio with Data-Bus controlled automatic activation (front camera only) by connecting a VS41 into the expansion port on the GM1A-RST.
