I have an 02 Celsior C package. (Live in Japan).
Towards the end of December, my navi screen started getting a blue tint to it. ONly the Navi and Navi menu screens had this problem. The audio/ac/etc.....were are normal color.
I took it to the dealer yesterday, and just got a call back from them.
From what I got from my conversation w/ them.......1) the cable from the navi display to the computer in the back is bad, so that needs to be replaced. and 2) even w/ that fix, they said it's possible that it will happen again, so they want to replace the navi computer.

Brand new-$5,000. 1 week.
Refurb-$2500. 2-3 weeks.
Fix the original unit and reinstall- $2000. 20 days.

It's under warranty from the place I bought it, so the dealer had to call them to find out what option to take. Brand new would be great, but I highly doubt that will happend. i'm thinking refurb or repair the original.

anyone have anything like this happen to their Navi screen?
the blue tint on it actually makes it darker than night mode.
So when I turned my headlights on, the navi display actually got a little brighter.
