PAC CM1 Onstar Chime Module

CM1 chime module for use with the OS-2 or OS-2BOSE interfaces only. The CM1 retains the warning chimes when you replace the factory radio and use an OS-2 or OS-2BOSE interface. Keep your seat belt, low fuel, parking brake, memory seats, security, low brake fluid and other safety chimes.

 

• The CM1 will not work by itself. If you need to retain warning chimes and the vehicle does not have Bose® or OnStar®, use the C2R-GM24.

 

All vehicles using an OS-2 or OS2-BOSE without a Premium(digital) Bose® amplifier.
