Thanks for your confirmation that the problem is likely my system. That means I'll be transcribing my waypoints for yesterday and today's hikes so I can do a master reset on the system. I've never needed to do one before, but I'd rather try it out than replace my GPS! ;-) Cheers, Sandy PS. Nice to keep my feet dry hiking today. For some reason, Sanibel isn't flooded even though the nearby mainland is.
