I just installed a avic n4 everything was working fine, shut the truck off did some cleaning up...came back and now all the thing does is the screen comes out and flips out, but nothing is lit...I tried reseting no luck...So now all i have is a screen that likes to flip in and out...Any thoughts...If i had an extra grand laying around i would throw it against the wall and go get another...Pioneer was very helpful "hmm sounds like its defective"

Hope you got it from an authorized dealer. Sounds like Pioneer is right

Check and recheck all your connections, especially between the brain and screen.
