Can someone give me a hint to connect this radio? I just can’t get the thing to run in the Audi. In nem Suzuki runs! In theory, a 12V and mass would have to be enough, right? The Audi has no ignition cable. Only lighting and calls non-indentified white. P.S. The quality of the radio is irrelevant in the mom. It’s just about cabling. So please don’t have a fundamental discussion.
