I have a 2010 Prius IV with Navi. At night I manually dim the accessory dash light dimmer to switch from day to night mode in the Navi. Should this happen automatically? I can't find a setting for it. Ira Warshaw North Palm Beach, FL
It should happen automatically. Does your Navi GPS screen background change from white to black when you turn your headlights on? It should unless you have Day Mode On set. If not, press the Display button on the side of the Nav. Then turn your headlights on. A tab should appear at the top of the screen that says Day Mode Screen Off or On. The Day Mode screen background is white and the night mode is black. If you want to stay white with headlights on, select On. If not, select Off. When on Day Mode, the dimming when headlights are turned on is not very noticeable but you should be able to see it dim slightly.
The OEM Navigation only automatically dims when you have your headlights on and lower the dimmer switch from FULL to a dimmer setting than full. I find this pretty annoying but I'm living with it. Check out this thread. Maybe cproaudio has some insight for you. http://priuschat.com/forums/gen-iii...353-auto-wipers-auto-headlights-ohh-yeah.html
