Is there a way to bi pass the E brake's ground to make the dvd play while driving in a 2008 mada.note and let the E brake dash light work correctly

Welcome to CA eric_70560!

Hopefully someone will chime in on it, but the only product that comes to mind is TVandNav2go. Not sure if they have a solution for the '08.

welcome to the club... i used PAC for my alpine.. it works great,,

If I insert a switch on the ground to make the E brake ground stay closed.Will the E brake light affect the truck's normal function

Do a search. There was a thread about this not too long ago. I don't think it was do-able yet do to a gyro in the Nav unit. Even with the E brake bypassed once the vehicle got to about 3 mph it switched back off.
