Does anyone know if the F900BT DVD Player work while your driving????

You will have to do the "bypass" which involves tricking the system into thinking that you are stationary and that the brake is on. This can be done in two ways; the 'hardware' bypass which involves soldering wires, or the software bypass which involves changing system files. I can't offer much more insight as I have not yet done either as my unit is still not integrated into my car (F500BT) but it is quite easy to do.

Just use your common sense and logical thinking and search "bypass" or something and you should find a picture tutorial somewhere...

Goodluck.
