Problem with Pioneer 690 ub

We took this HU from my friend's truck and installed it in mine. Everything works fine except for the "entertainment screen" or "screen saver". It starts out with the background black and the letters/number/images blue, then it flip-flops colors every 30 seconds or so (blue background and black letters). I thought it might be that certian screen, but it does it with everyone and it never did that while installed in my friend's truck.

I looked through the manual, but couldn't find a thing. Any suggestions?

Thanks for the help in advance!
