Registered 1997 SLK230 Kompressor
I'm fitting a Pioneer SPH 10BT smartphone receiver unit and it is plug and play and works fine. It's a pain to get in and out, so before I push it all the way in I thought I'd better check what the C connector that I removed from the original 1997 cassette unit does. It has two brown wires going to it and seems redundant. Thanks in advance.
