I am trying to install a new cd player in my C230 . I have gone over the wire diagram over and over and still don't understand why the cd player will not turn on. My factory one works with no issues. I have installed many aftermarket cd-players in the past and just not understanding what I am doing wrong.


Any Ideas ??

Where did you connect for your ACC wire(red wire)? I just installed a Pioneer AVH 5800 in my 07 with no issue.
