I've had a read through many TV tuner posts, on here and other MB sites, and cannot find what I'm looking for. I suppose I could have a look myself, but I've never taken the trim off behind the seats and don't imagine it to be a few minutes job. In a SL500 (R230), are the four aerial connectors that fit into the tuner joined together or can they be unplugged individually? From pictures I can see the cables are separate, but it's not clear about the connectors. Does anyone know whether the cable is 50 or 75ohms?
