Prius forum, I think there was thread on this issue but I couldn't find it. I have a Prius C II and have experienced the glare problem on the Nav screen. I tried to adjust the contrast and brightness but it didn't help. Has anyone found a solution for this? Jerryd
Dark tint on the rear passenger window helps if you're interested in that approach. You can try it by covering the rear passenger window with a dark towel and sitting in the drivers seat and looking at the screen again.
Prius forum, Thanks for the replies. It is a III my bad. I did turn the brightness all the way but it didn't seem to help much. jerryd
also, for those who turn on their headlights during daytime, adjust for that as well (brightness up, contrast down). couldn't see the screen at all before adjusting
you can also adjust to keep it bright at all time with the dimmer sw just left of the steering wheel.
