Navigation screen goes blank?
I have a 2002 MDX with a wonky navigation screen.
I bought the car used in 2006, and for the first year and a half, everything was fine. Then, about a year ago, the nav screen started going blank periodically. I'd be driving along, and suddenly I'd notice that the screen was black. If I was in the middle of a plotted route, I would still hear voice prompts, but the screen would be black and the touch screen would appear to be inoperative. I believe the buttons didn't work either, but I really couldn't tell.
As time has gone on, it's gotten worse. At this point, the screen is black most of the time, with only occasional times when the screen will light up when I first start the car. Within a few minutes though, it will be black again. Outside temperature doesn't seem to matter, bumps and the like don't seem to matter.
I've been hesitant to try to pull the trim panel to get to the screen because I don't want to break it, but it's all kinds of frustrating.
Has anyone else seen this sort of behavior before? Is there a fix that doesn't involve spending multiple thousands of dollars on a replace nav screen?
