I have had my F900 installed in my car (over here in the UK) for about 6 months or so. Removed it a week ago and it had been sitting in the dining room on the table until yesterday when I fitted it into our new car.

 

All of a sudden I now have a pink / purple tint on some sections of the screen. It seems to be where icons / text use whte to shade, nstead of being white these are pink. Some plain white sections are true white, i.e. when booting the text on the logo is white, so when displaying a picture it is fine. When on the navigation screen however the text showing distance / time etc. is pink. On the ipod screen the play / pause icons are pink.

 

I have just updated to v2 of the pioneer firmware and that hasn't fixed the problem Have emailed pioneer to ask them, but think it may need to be swapped out under warranty
