After a day of hiking, 64S can't connect to PC, boots to a diagnostic screen and is completely unusable. No combination of keystrokes or button pushing makes any difference. I can't even factory reset since it defaults to these screens immediately after booting.
I guess it's just another dead garmin product for the bin? I guess this will be about the 4th garmin product I've junked in 10 years. Not much of a surprise at this point, to be honest.
