hey guys im new here...well ive just installed this indash everything works fine but when i try to play dvds i can only hear it...you can hear the movie playing but u cant see it...u think this is due to wrong wiring or the indash has a problem???all help is greatly appreciated thanks...

My 6800dvd did the same. You need to release the parking brake and re-apply it. I can't remember exactly the whole routine. I did it and mine came up fine afterwards.I may have missed something inbetween but that's what I remember.
