I have a 2004 RX-8 that I just bought and cannot figure out how to turn the Navigation screen to a black background with the map showing when driving at dark. When I turn my headlights on the screen stays the same as daytime and I have it set for the night transition. I have checked the search on this site and have not found any information.

 

click menu, it's under the settings.
it also should be covered in your owner's manual. If you don't have it, go to mazdausa.com, register as an owner and you can download a pdf version.

 

Try the switch located to the left of your steeling wheel... the same switch that controls your guage panel
