hello guys,
i have c220cdi 2008 (w204)
does anybody knows if i can change my car's audio system (is the simple with mp3 player only and 5inch display) to put the system with 7inch display and navigation.?
if i can what i need to install it?
i have the audio system but i dont have extrA wires or plugs..
in first picture is the simple one
in second is the system with the navi
also have and one plug different on the display

please help..

Pull up the search function and search for the word "retrofit" in the W204 section and you'll find plenty of threads, parts lists etc.

EDIT: Didn't actually have to look too far. Here is vic viper's thread that can be found from page 2. https://mbworld.org/forums/c-class-w...-retrofit.html I think he also has another thread about the same subject somewhere.

which one i must get to make the system works..
i dont want gps and else i want to work dvd radio and the display
