CRUX Wiring Interface

Installing a new car stereo can often mean losing your GM vehicle's factory warning chimes and bypassing your Bose system. Crux's SOCGM-17B wiring interface solves this problem, allowing you to install a new receiver while retaining the safety chimes and the standard Bose amplifier. The interface does not support the Y-91 digital Bose systems found in the Escalade and Hummer, and does not retain OnStar or steering wheel audio controls.
