X3 Triple Auxiliary Audio Input with X3-GM12 Cadillac, Chevrolet, GMC, Oldsmobile and Pontiac Harness for vehicles with the class II factory radio.

The X3 System is composed of a universal brain module and a wired remote input switcher with display plus a vehicle specific wiring harness. The X3-GM12 connects to the X3 (brain module) and allows 3 auxiliary audio sources to be connected to the OEM radio when a CD Changer, Satellite Radio or Rear Seat Entertainment (RSE) System is present. This converter will interrupt the audio of the CD Changer, Satellite Radio or RSE, switching from AUX1, AUX2, AUX3 and back to CD Changer, satellite Radio or RSE audio.

X3-GM12 harness installs behind the radio.
