Happened again yesterday as I left work. Couldn't read the nav disk. I drove back to the apartment, parked the X5 in the parking garage, walked the dogs, and then checked out the X5. Nav worked perfectly.

I think it is happening now b/c I am parking it outside at work so it is getting toasty inside (at home I park in a parking garage). Something about my nav system doesn't like the heat, I guess...

I'm going to try the old nav disc and tonight if it does it again and see if it makes any difference.
