Prius iv with upgraded nav (sunroof package)...after a year and 15k miles, all of a sudden display stays on daylight mode at night. It is blinding! What happenrd and how can I fix it?
There's a knob on the left of the steering wheel to adjust the dash lights. You probably moved it to full bright all the time.
Rotate dimmer switch to full bright. Now rotate is back to full dim. (( if you go past full bright it will lock at full bright and will not auto dim when you turn of your headlights.)
