Hi im new to the forum!

I recently bought a Mercedes S320cdi, its obsidian black and its practically brand new..

well i have a bit of a problem so i was wondering if someone could help me out. ive got a sat nav and dvd player in the car which are both from Mercedes and the thing is as part of their safety features the dvd player stops playing the dvd as soon as you you start driving and a safety message is displayed! What i wanted to have done was to disable that feature so the dvd still plays whilst the car is moving...

If anyone knows what i need to do in order for me to do that i would really grateful for the help and suggestions!

Thanks
Mo
