My 2012 ISF nav system display does not go into night with the headlights on. The owners manual indicates if I press display there is a night option setting, but I don't see it. I brought it into the dealer for an inspection as I just bought the car, and afterward it did go into a night display for a while. Now it just stays in day mode. Any ideas for a fix?

 

Check the dimming setting to the left of the steering wheel. If this is on full brightness, all the way to the right where it clicks, the nav will no longer go into night mode.

 

This was the issue with my car 3 years ago. I read a thread on here about it and have adjusted the switch so that it auto dims.
