I put a dvd movie in my d3 and it started playing fine as soon as i take off (drive) the picture goes away but the dvd is still playing voice only no picture. Any idea why this is? yes i did the bypass so i don't have to use my emergency brake,I also serched first (nothing)

try re-grounding the parking brake wire to another place. maybe where you have it grounded now is not good enough. i grounded my parking brake wire to the ground coming from the stock harness itself. it needs bare metal. good luck!

thanks!!
