My 2010 GX sat for about a year in the garage. When we started it up, we noticed a yellow tint to the navigation screen. Has anyone else noticed a yellow tint on the early generation GX navigation screen?

 

I have seen that issue reported elsewhere (across many Lexus models of the era) and usually indicates a failure of the LCD screen requiring replacement.

I haven’t looked around lately on sourcing replacement screens but you may want to consider a 3rd party head unit replacement as an option as well.
