*** SOLD *** Plugs into GM radios equipped with a CD auxiliary port and allows you to play other devices thru your factory radio - no need to open your radio, solder additional wires and add a 3.5mm jack. In great condition, includes instructions, wiring harness for GM radios and 3.5mm plug to RCA in cable.
I had used it with a Pontiac Monsoon AM/FM/CD radio, using my phone as input for my music catalog. Link below shows compatible GM radios, instruction sheet and add'l links to sites that sold this unit before it was discontinued due to lack of demand. Works great - asking $60 + actual shipping cost (UPS, USPS, FedEx)
Auxiliary Audio Input InterfaceThanks for looking! *** SOLD ***
