Watch TV / Videotext during driving
This works on all BMW 5/7 Series with the Mark I Navigation System (the one with the male voice).
On Mark II (the newer version with the female voice) you have to use "brightness" instead of
contrast for TV and "color" instead of brightness for videotext to get the trick to work.
