Wow!    I master my BMW 740 Now!

Its been long time looking for a way to keep my screen running on my ‘1999 740IL‘.. but.. I’ve finally found how to trick BMW company and keep the TV running while driving..

My system is Mark II (the newer version with the female voice) and i had to use “brightness” instead of contrast for TV and “color” instead of brightness for videotext to get the trick to work.

Now.. I will reveal the secret!!… Just follow the instructions below and have fun!

1. set ignition to pos. II .
2. enter TV mode .
3. enter “settings” .
4. enter “contrast” or “brightness” .
5. when the green contrast bar is visible, push the knob and keep it pressed .
6. turn ignition off (keep button pressed!) .
7. wait 8-10 seconds (timing must be accurate!) .
8. release the knob .
9. turn on ignition again .

Now the TV will operate while the car is in motion.

Note: am not sure if this will work on 5 series or not .. you just try it your self.
