ok, got my d3 just finished installing it with the bypass and the VSS...now heres the problem the nav work perfect, its just dvd i can here the voice just no picture, when i got pass 10 mph screen blacks out..i checked the wiring everything looks tight...now i did use the ground wire in the wiring harness does this have effect the dvd watching?? it just tells me people in the front seat cant watch the moive while vechile is moving... so any ideas on what i should check...

i moved the mute wire grounded the parking brake to the ground what else is there??

that's it. You have a bad connection on one of those two wires.

k thanks ill check it out again..thanks

Make sure the spot you used for ground is actually a good ground. All metal behind the dash is not always grounded. Get yourself a digital multimeter and see if the location you picked is a proper ground.

right now its grouned to wire harness and attached to factory harness..this shouldnt make a differnet should it??

depends on the vehicle. Some cars don't provide a ground in the factory harness. Even though the aftermarket harness has a ground pin in it.

And some vehicle's harness grounds are just plain crappy.

It never hurts to ground it all to the chassis instead.

Exactly. I have an 01 Altima that I had an Alpine HU in. It would not work of the stock harness ground at all even though the factory radio did. So I had to ground it to the chasis in order for it to work. So every radio I ever installed after that, I just go straight for the chasis ground.

thanks for everyone support..I got it to work... i just ran a ground to the body.. works PERFECT..
