I have an early build (3000-range) with nearly 18K miles. Yesterday I had a problem where my navi screen would remain off. I'm used to seeing a dark screen initially as I usually don't respond to the advisory screen quickly enough. In that situation, depressing the map or audio buttons will cause it to come up. Yesterday, however, no matter which button I pressed, the screen would remain off/dark. I pulled off to a side street, shut off the car, and restarted. The screen seemed to flicker a bit when I shut the car off, but it did come up without issue upon the restart.

I searched the forums and didn't see any similar reports. I'm not going to lose any sleep over this unless it continues to occur.

 

navi system is like a computer, it has flukes, one day mine just blanked out on me, nothing worked, a simple restart of the car, thus rebooting the navi solved it. Nothing to worry about, probably wont come back

 

Experienced this today. Don't you just love the search feature. If only the newbs would learn how to use it.
