Hello, everyone. First of all, love this website! The gurus are great!
Tried searching but couldn't find a thread that addresses this query.
Anyway, I've retrofitted my US 2001 CLK 320cab (w208) with a euro COMAND and it works great except for negligible clock issues. I've decided to add an auxiliary input. I purchased an Aux input wiring loom from Mercedes (part #A210 440 50 05) and now I have the 3.5 mm jack in the glove compartment and routed the white four pin connector to the back of the COMAND.
I assume that I have to cut off the male connector and connect the wires to the C2 connector. Correct me if I'm wrong but isn't the part number for the pins A035 545 73 28? More importantly, where do the pins go in the C2 connector? The fours wires are brown, yellow, black and one is "bare."

By the way, after this project, I will be working on a COMAND retrofit on my 2004 C240 4MATIC wagon. Just waiting on wiring loom adapter for W203 from Comand Online Ltd.

Thanks so much!!!
