I have noticed recently that the auto mode to switch between the night/day mode on my navigation doesn't work anymore. Usually when I turn on my headlights the screen would change into the night mode automatically. Now I have to do it manually everytime. Does anyone know might be causing this? Thanks.

 

Someone might have changed the setting. Go to setup>>>make sure it's on auto.

 

Push the adjustment button so that the instrument panel lighting is one setting below "Max." If the instrument panel lights are at "max" with the headlights off, the displays (including the Navi) will stay in "max" and will not go into night mode.

thank you I'll give it a try.

 

I agree with Will, had the same problem with 07 RDX, adjusted instrument panel lighting to be set just below "Max" and Navi went back to dimming when headlights were turned on.
