Hello, I can't answer exactly because the cable is more radio equipment than car-related. The device is not original Ford, but a Grundig double DIN. Also, I don't have an Audi, but a Ford. Sorry not to be able to help more. Sincerely yours. S. Veltri

Hello

It doesn't depend on the vehicle, but on the radio/CD device. I connected the input to the CD player with this cable. You should look up the radio/CD type and then the connections on the Internet.
Nothing works without AUX IN.
