I had to go to Sun Valley, Idaho (about 2 hours away) for a meeting. Used my NAV to make sure I was paying attention to my speed, as the speeds change quite a bit.

So when I got out of my meeting, I turned on my NAV. But it told me I was in San Marcos, Texas. I turned it off and on several times, but it thought it was still in Texas. Drove out of Sun Valley and stopped and shut my car off for awhile. Then it was ok. Weird.
