Hello everyone , merry Christmas to all of you. I have buy a used interior set with tv screens & dvd player on the rear. I have a wire cable ( the guy who sell it to me send me the all wire connection cable ) for connecting the entertainment system. I find out to connect the dvd and front seats. The are a pin connector to connect with the command but they are not space for the connector. I coding with Xentry the entertainment and are ready and not connect install. Have anyone experience about this.
the car is Mercedes w221 350cdi 2007 model
the seats with the entertainment is 2010 model w221

the 2007 car has NTG 3.0
the 2010 car has NTG 3.5

the 3.5 is a later comand unit with changes to its wiring - and (certainly) a different front screen

some clues to the early set up around post #24 https://mbworld.org/forums/s-class-w...ries-work.html
