make a ground for ur paking brake wire and then it will bypass that

ground the parking brake wire so it will bypass that and the u can watch dvds

try to buy a good lense cleaner disk , or carefully clean the lense surface with one cotton tipped applicator very soft ,making circular movement .it work to me !

Just hook up the parking brake safety switch from the unit to ground. That will do the trick. Hope this helps

With your ipod not connected, go to setting than video, then turn on the output.

or the parking prake wire is not grounded... that's what happened to me. Just find a spot to ground the parking brake wire and video should appear.

The problem I had was with the remote control unit for the steering wheel controls. It shorted out. The head unit was fine. But, when the sterring control unit is shorted it also prevents the hand held remote from working.

Yes opening the unit with the eject button then manually closing the unit halfwaly, and disconecting the battery for like 30 secs.... Here
