i have a alpine iva-nav-1 it has the to leads to the foot brake and the parking brake. when i put it in i grouded both of them out to watch the dvd. and it worked but when i shut off the truck and started it back up it did not work. the guy a the car stareo place said the one had to be on a flip swich and the other on a push swich. i did it like he said and it still did not work. so can some one tell me what i have to do.
