The OS-3BOSE is a plug and play interface that allows replacement of a General Motors GMLAN factory radio. It will maintain operation of the OnStar system, Bose amplifier and speakers. The OS-3BOSE has on board switching to allow audio from the OnStar system to play through the two front factory speakers when OnStar is active. This interface retains all warning chimes, the audible turn signal indicators, and the vehicle rear parking assist system. Rear seat audio headphone jacks will also remain active and are designed for use with dual zone radios.
