Introduction and Features
Important Notes
1. Aftermarket radio must have an auxiliary input in order to retain RSE audio with additional harness sold separately. Part#
(GMRVD2).
2. Aftermarket radios with a 2-wire resistive based SWC circuit will not have default button assignments programmed. Please
refer to the owners manual of the radio you are installing to nd out the proper SWC programming procedure.
3. If the vehicle chimes when the radio is removed, the CMX is not necessary. In order to get the best possible sound out of the
CMX, please mount it in a place free and clear of any obstructions, preferably as close as possible to the bottom of the dash
pointing down toward the oor of the vehicle.
