i got pulled over the other night in apple valley cause my rear lisence plate was in my window and not on my bumper. after he stopped me he noticed my tv that i have molded in the center air vent bezel. he didnt give me a ticket for it but he told me its illegal which i was a little aware of already. my question is, would it be considered legal to have if i wired the power button ground through the parking break making it so i could only have it on while the car is parked? also, how is it possable for cars with navigation to have tvs legally?

I think its only illegal if its on. They cant give you a ticket if its off. Like youi said there are plenty of cars with GPS and LCD screens up front..

In dash monitors are legal, but they are illegal to be on when the vehicle is in motion if the drive can see it.
All of ours we install HAVE to have the ebrake wire hooked up for liablity reasons. That is if they are indash.

k, thats what i thought. when he asked me if i ever have it on while driving i told him the truth and said yes considering he was behind me at a stoplight shining a spotlight into my car from behind. ill rewire it when i have time.
