I have noticed that over the 9 months that I have had my TL the Navi display seems to be dim when the car first starts and then gradually gets brighter as it is left on. When I first got the car I seem to remember that it was bright when I first turned it on and didn't change. Has anyone else noticed a change in Navi brightness as it is left on? Could this behavior indicate some sort of trouble in the display?

 

This happens to me too, but only when it's really cold outside...

 

If your in a cold climate it will. It's LCD (liquid crystal display). So in order to become more vibrant the display needs to warm up.

 

Cold temp...

 

missed opportunity for Christmas ... "here NAV I knitted you this nice sweater"

anyone have a link for a NAV cozy?!? I checked e-bay ... no luck

 

I see that too...

 

yup... i also think it started brighter when i first got the car. but its not that annoying, hopefully doesnt damage anything.
