PAC's OS-1 BOSE kit 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 OEM-1 premium sound system interface, which allows quick connection of an aftermarket receiver (or an additional amplifier) to the GM Bose system, without the need to cut wiring;
  • the OS-1 adapter, which allows the use of the OnStar system with an aftermarket receiver. The OS-1 has on-board switching and built-in amplification that allows audio from the OnStar system to play through the two front speakers (factory or replacement) when OnStar is active, while muting the replacement radio.

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). 1-year warranty.

Important Note: The OS-1 BOSE 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 BOSE kit will not work. In order to determine compatibility with your vehicle, please use the vehicle selector on our site, or call a Sales Advisor at 1-888-955-6000.
