Advice needed.
I'm posting this here rather than in a new thread, because I need an answer soon. When I got to work just now, stopped my Garmin 800's trip timer, then held down Lap/Reset to save the trip, it stopped counting down at 1, then the Garmin just froze, and is now completely unresponsive and won't even turn off. Does anyone know of an easy fix for this, or just a way to turn it off? I don't have any screwdrivers (at work, anyway) small enough to take its back panel off, to try to reseat its battery (if that's even possible).
Thanks,
--- Victor.
