Hey guys im new to avic411 but im having a small problem, I recently hooked up my pioneer 4000 to a 2007 scion tc and installed a 80 gig zune to the rear av inputs and now everytime I listen to the radio or try to watch a dvd my screen goes to "caution images on screen might appear reversed" or something like that, I was really hoping the av inputs would work because I have most of my videos on my zune. If anyone could help it would be greatly appreciated thanks.
