Navigation system failure. Hardware?

maybe something came unplugged. try disconnecting the 12v negative for 15 minutes and see if it reboots.

 

the battery is in the hatch on the right rear corner. there is a triangular piece of flooring in the fender that lifts up, and the battery is underneath.
the black cable is negative

 

or you could look for the fuse for the dvd and pull it out and put it back

 

I have not experienced this problem with the unit on our Gen 2 car, but I think it is likely that given the location of the DVD player under the driver seat, it could be susceptible to collecting dust, etc. in its innards, to the point where the lens might need cleaning. I have a CD/DVD lens cleaning kit that is really just a blank CD with small brushes embedded on the underside. I have used it on several occasions to clean the drives on my computer, just for the purpose of establishing that the reason my drive wasn't reading a disk was that the disk itself was damaged rather than the drive unit. I don't know how common it is for the lens to get dust on it, but I would say trying something like that on your unit might be worth a shot.

 

really? try an electronics store, best buy, target, etc. amazon was my first hit: dvd cleaner disc

 

2010/11 map DVD isn't under the seat like Gen 2, it's right behind the map screen. But yeah, what's to lose by trying a cleaner disc?
