For those people whith ML and want to enable DVD while in motion, all what they have to do
EXACTLY what Sonartech did (post #1)
PLUS grounding the E-Brake wire (which is discribed here)...
The E-Brake wire is located in the same connector that have the speed signal... It's a yellow wire Pin#23 (
NOT Pin#13 and NOT Pin#25)...
Now, cut that wire... After you cut it, you will have two ends... One end is going to the car, the other end is going to the Display ECU.. Tape off the end that is going to the car, we don't need it... We need to gound the end that is going to the Display ECU... The closest ground wire in located in Pin#10 in the same connector (Black/White wire)...
DO NOT CUT the ground wire!! All what you have to do is to "add" the yellow wire (going to the Display ECU) to the ground (Back/White) wire then solder the wires and tape off the yellow wire that is going to the car...
Warning: If you accidentally gound the yellow end that is going to the car, you MIGHT damage your car and you might get the ABS, VSA lights and you MIGHT have to visit your dealer!!
