Occasionally when navigating, my phone will freeze (the display and also the music, if it's playing) then reboot a few seconds later. I realised today that while it's happened in other places, driving past Falkirk seems to trigger it.
My question is: Given that I'm away from my PC, and it doesn't happen very often, how can I diagnose the (general, rather than location-specific) issue? I've got an HTC Desire running CM7 and I'm comfortable using a shell.
