Bought a new-to-me nav unit and this came with it. $40 plus shipping

Info:
The OS-2 is a plug and play interface that allows replacement of a General Motors Class II (Class 2) factory stereo and maintain operation of the OnStar® system for select 2000 & Up GM vehicles. The OS-2 has on board switching, and amplification to allow audio from the OnStar® system to play through the two front factory speakers when OnStar® is active, and mute the new aftermarket replacement radio. Retains door chimes when used with PAC’s optional CM1 chime module. The OS-2 can also be used when a stereo and amplifier combination system is installed. Separate speakers can be added if desired.

Comes with the CM1 chime module.
