Odd issue with my navigation screen
This will sound very odd, but since this is the second summer that I have had the car I have noticed that the screen turns purple in hot weather.
Sounds crazy, I know, but I'm serious. When the weather is hot- above 90 degrees probably- the screen turns a deep, deep purple color. This was my theory last year as the car stopped doing it as the weather cooled off and we got into fall, but now that the weather is back to sweltering, it's doing it again.
I am sure it's the weather because the last two days here have been quite mild and my nav screen has been normal. It's also usually not affected during the evenings when the temps are 70s-80s, but during the summer days of 90+ it turns purple.
It's also only the map screen that's purple. If I go to climate, destination, audio, etc...everything is completely fine and dandy. It's just the home, map screen.
I asked the dealer recently and they said that short of replacing the entire unit, there isn't anything that can be done.
Any ideas? Very bizarre, I know...

It turns off only when the temperature cools down to less than 90 degrees or so.

Just out of curiosity... you know the screen has different color modes right? I say this ONLY because shortly after getting the car, I too noticed ONLY the nav change color. You can readjust this in the settings.
Let me know if that's it.

So, the only screen thats purple is the home screen? Probably a setting. I dont have the navi but its logic that if the unit was failing, it would be purple all the time.

Yeah, I have a '02 GS430 with the stock NAV and I have also notice the light purple tint when it's hot outside. It doesn't affect the NAV in anyway, maybe the heat causes something to change in the LCD crystals??

My navigation seems to do the opposite. I have always noticed when it was cold(50 and below, cold to los angeles people) my screen turns purple. I have never had any problems with heat even in triple digit in vegas or phoenix. I have experienced issues with other LCD such as laptops or stereo displays in the cold as well.

My guess is since it happens on the maps screen only and either when hot, or cold in the other case, it is the beginning signs of an electronic parts (Bad cap, resistor ect.) in the DVD navigation drive unit, or its RGB output stage. But, that is on;y a guess.

My NAV goes dim and the buttons "lock out" upon starting when its been sitting outside in cold weather (below 40F). Once the car heats up, you have to restart the car to re-boot the NAV computer to get touch-screen functionality back.
That happened for a few years every Winter if parked outside, and now, the color on the screen has gone out permanently (but touch-screen still working in warmer weather)... maybe the green or blue has died, and it's mostly black and tan/orange colors only. Still usable, but looks pretty bad.
