I have Irish model 2009 E220 CDI (W211) It has 6 CD changer + single CD player + radio, with IPhone cradle, all operated by controls on steering with viewing on dash.
I understand that I need to fit comand system and interface to play my ipod through system. (Transmitter to blank radio station not acceptable).

Can you please advise me re list of parts and numbers that I will need to make a success of this installation, if it is possible.

 

Thank you, I have. Very little experience of fitting unit in Ireland and cost is usual Irish.
