My GPS quit working yesterday in Ruidoso, NM. Was working great all weekend, even in the mountains. Yesterday morning, it refused to find my location. Rebooted several times (didn't remove battery-should have) but it never kicked in. Turned GPS off, but kept turning it on periodically just to check it on the drive back to Austin. When we got home, I checked it one more time and it was working?!?!? I'm very glad it's working, but just wonder why it stopped? I really missed it!
