I am wondering if anyone has the problem I have. I live in Los Angeles so FM transmitters are crap. My car is an 2004 ML 500 with GPS sysytem which means the front panel comes down to reveil my cassette deck. I have many wires and want to know if anyone has this system and has installed some sort of RCA jacks to get around this. I have been told that Mercedes Fiber Optics in its system which makes it difficult to do.
