Mercedes CLS DVD COMAND System

Ive just been getting a Mercedes CLS with the DVD COMAND system fitted and I was wondering if anyone knows the codes to get into the engineering menu so I can unlock the DVD system so that my passengers can watch the TV / DVD whilst Im driving.

Tried a couple of the better know tricks (AUDIO - MUTE - PHONE DOWN - SERV) but with no joy!!!!! All help appreciated!!!!

Thanks in advance
