I have a computer navigation system that goes on and off whenever it likes. It seems to be a mechanical problem because sometimes when I go over a lot of bumps it would turn on or off.

Does/did anyone else have this problem?

It started after I had someone replace the glass window on my left front door. I wonder if that caused it?

Have had this problem over a year now.

sometimes the NAV would reboot over and over while I’m driving. For the most part it remains off with a black screen.

 

Nobody had intermittent problem with their NAV?

 

Nope. But previously reported issue like this was fixed by replacing the whole unit.

 

Do you have a link for that thread?
