Pioneer DVD/Nav Unit in an 05 C230 SS
The biggest hurdle you face in the beginning AFAIK is the dash kit for the '05s. I've heard people complaining about not having a dash kit for that model (the 02-04 dash is different). I would square that away before beginning.
I was thinking of putting in a Pioneer NAV in. If I do it, I'll post something up on it. In any event, let us know how it goes.
I have the AVIC-N2 installed in my 2003 c320, but I dont think they have a kit for the 05s and up yet, but I remember someone customizing it, and maybe u can have dimensions and build ur own box, but u gota get new cables, the original MB ones are fiber optic, so it might be a pain in the butt, the steering wheel controls wont work unless u put a compatible interface, then the radio wont work well either, havnt found out a answer to that one yet, but I advise u to get the Eurospec NAV
