Thanks for all the sugggestions and stories and evil plots to get a new GPS unit. Anyway, I peformed a firmware update and cleaned the battery terminals. I strolled out the the end of the driveway with it and the accuracy was down to 6 - 8 feet! I've rarely seen it below 14 and usually it was up around 18 - 22. While I haven't field tested it amongst the trees, if this is any indication of things to come, I'm one happy clam. Happy trails to all! (Now I don't get to drop it off a cliff, though.)
