Hello, I currently have a 2006 Prius with the built in navigation. Today when I start up the car, the map display is in a repeated loop of "System Loading.... Don't turn power off" It has been working since I got the car, and I have done a map update a couple years back but it has been working until now. Everything else in the display appears to work (Engine screen, Weather, Audio, etc). Is my navigation DVD dead? or is it something more serious before I go ahead and get another one?
Try cleaning the DVD and putting it back into the drive. If that doesn't work, try power cycling the Nav unit. Tom
