PAC's OS-1 wiring interface lets you replace a General Motors radio (without RDS) with an aftermarket receiver while maintaining operation of the OnStar® system and the GM Bose® amplifier and speakers. The kit includes:
The OS-1 can also send OnStar audio to an external set of speakers if desired. There are separate right and left gain controls for OnStar audio, and an LED indicator that turns on when the OS-1 receives an "On" command from the OnStar® system. Dimensions: 4-13/16"W x 1-1/16"H x 2"D (OS-1 adapter). Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.
Important Note: The OS-1 kit will interface with GM Delco/Bose radios that do NOT have the "RDS" option. If there is an "RDS" logo on the radio face, the OS-1 kit will not work. Warranty: 1 year.
