My brother just got a new touchscreen HU. It is the Jensen Phase Linear UV10 In-Dash . There is a wire labeled "prksw" that is suppose to hook up somehow to the parking break that would only allow him to watch a dvd while the car is in park. He is wondering if there is any way to bypass this. I couldn't help him so I told him that I would ask on here.
Well it's illegal once the car starts moving. But who's really going to catch something like that? I personally would have it bypassed myself, heh. But I'm not a movie person so I don't really care too much for A/V head units other than navigational features.
