For about the past week or so, my navi screen hasn't been changing between day mode and night mode when my headlights turn on. Also, my navi screen is set to "auto". I can manually change the screen from light to dark, but it won't do it automatically anymore.

Any thoughts?

 

It sounds like you've got the instrument panel lighting set on "Max."
Decrease the IP lighting by one bar below "Max"; hopefully that solves the problem.

 

I'm gonna go try it right now.

 

That did it! Thanks.
