I tried to go for a run tonight, selecting 'do course' for my usual route. The 310 locked up beeping and vibrating permanently, with the screen locked up. I read the instructions and reset with the mode and reset button, it rebooted but hangs up on the Garmin splash screen. No other buttons work, all I can do is keep resetting, and it just hang there on the start up screen!!:mad:
Any ideas before I stamp on it!?
