Hey about a year ago I had bought a double din harness and put a pioneer 3500 bt screen in and for some reason the guy who installed it was supposed to put some sort of by-pas in it and let youtube and everything else work and it never did. I never got around to doing it. If anyone knows what i am talking about i always get the message you can not view while car is in motion. even when i am parked and the engine is not even on.

 

You have to ground out the parking break wiring. Once you do that you can watch movies or whatever while driving.
