GPS with creepy crawly wierd stuff

[FOG]

OK, I know it's almost Halloween, but I just noticed my GPS with some weird stuff inside on the screen.
Anyone seen this before? My GPS is on the flybridge and I do keep a cover on it.
Plan to take it apart to investigate and clean, but I thought I would ask the experts first.
Maybe some kind of mold???????????

Greetings,
Mr. F. Is this anywhere near the New Madrid fault line?

It doesn't look like any kind of LCD failure I've ever seen. If there is a protective screen over the actual LCD screen - that could indeed be stuff "growing" between the two screens. Normally those units are sealed but maybe yours lost its seal.

That's the dreaded glass fungus Best way to get rid of it is to heat it up to 1000c for 10 minutes

The weird stuff is always in the same place on the display when switching modes. So I agree that it's not an LCD failure and probably some kind of growth between the LCD panel and glass/plastic screen due to a bad seal.

I'm still hoping someone has seen this before and has a "tried & true" fix for it.

However, I did leave it turned on for several hours with the cover on to heat it up, ... but no joy.

I just realized that I never followed up with what I found when I took it apart.

There was a plastic covering with a very slight smoke tint glued to the glass LCD screen. The glue was separating (air pockets) between the glass and plastic covering. That separation caused the weird spider like blotches on the screen.
I carefully removed the plastic covering and cleaned the glue residue off the screen and now call it fixed.
