I need your help....I have a new Mercedes SLK 200 (Europe - Switzerland) with DVD comander APS (version 4.1 I think) and I want to unlock the video because when I drive is not possible (for security) to watch videos...and of course the image disappears...
What about this secret menu:
select radio and in the same time 1 - 3 - mute for 8 seconds...
and a technical menu appears...
