Just bought the Kenwood DDX7015 Double Din DVD player for my 5th Gen. Does anyone know (in general) how to make it so that it plays when I'm driving and not only when I'm on a stop?

I heard something about grouding the brake wire? More advice needed.

Thanks everyone.

 

yea just ground the sucker,
think of it this way, positve flow's through negtive. your system's brake light is triggered when it is grounded.
