DVD in radio problem.
 

Hey guys i installed my jvc radio yesterday and you can watch dvds on it. Only problem is my dvd doesn't show up it says "parking brake". My parking brake is up though. i thought it would only say that if it was down because it's illegal to drive while watching a dvd but i don't know why it won't work while parked. Any help?

You installed your JVC superultramegadildogenerator incorrectly, then.
