George,

The European C class set-up is different as the US set-up (on certain issues that is). The European W202 C classes have cell phones build in the car like this:



We do not have an additional cell phone speaker in the rear and the microphones are just built in near the rear view mirror.
I am not sure about the wire color code...one speaker wire is blue with a yellow line, the other wire is not in my memory at this moment...but then again: I doubt whether the US color codes are the same for the cell phone parts.

greetingz,
