Normally, in the Set-Up Screen 1, I set the Display to "Auto" so that whenever I turn on the headlights the Map Display will turn dark (Night display). But after my car battery was disconnected and reconnected, that feature does not work anymore. What could have happened ? And how can I fix this? Much appreciated if anyone can help me out!

 

press the max button, to the left of the steering wheel, to make sure your not at max brightness.
