I have a new Pioneer 930BT and would like to be able to play DVDs and impute address information while moving, (passenger). I think it has something to do with grounding the parking brake, but not sure. Any help would be greatly appreciated. Thanks RB
well it used to work just grounding the parking break but not the case anymore... now u have to show a change in the ground for it to work... so if u hook a switch up to the long parking break wire and ground it.. then after the dvd player turns on flip the switch to off and then back to on and it should work then... let me know how it works out for u
