My AVIC-Z2 unit won't automatically insert a disc. I push it all the way in, and there is no sort of mechanical noises of the unit attempting to pull it in. I can however eject the disc without any problems. Also when looking through settings, the DVD player button is greyed out like it's not a source or set up. What steps should I go to get a working DVD player ? I really don't want to spend an extra grand or so to get a working DVD player, I'm hoping it's something relatively simple. Thanks for your help
