i bought a cd changer for a 07 c230. bought the cables from the dealer. trying to install it and got power and everything but when pushing the cdc button on the radio, it says no cdc..... i'm guessing i might of connected the wires in the wrong spot.
does any1 know which wire to which wire i have to connect to make it right. a radio wiring diagram would be helpful.

 

you might have to reset the deck....although when you do that make sure you have the radio code, to reset itunplug the battery for about 15 minutes... that might reset it if not call your dealership to see ifthe deckhas a reset on the radio..you might have to press a combination of buttons to do it....DES
