avh-5700

ok i got a pioneer avh 5700 and trying to get the video to play while driving what do i have to do to trick it so i can drive while watching advd

what kind of truck is it in? I think that in an S10 it has something to do with the parking brake

it doesn't matter what truck/car its in u have to hook it up to a on/off toggle switch if you don't hook them up to the parking brake. hook up one wire to the parking brake wire and the other to the ground from the toggle, then turn it on/off a few time and the screen comes on
