I have to agree with the comments made a few days ago by another customer: "They couldn't have made map-updating more difficult or awkward....It's a pity to see such a well-designed product so poorly backed up."I'm on my second Garmin Sat Nav. My first worked fine...until I was updating the maps a few years ago. I ended up buying a new one as the update process rendered my old Garmin device un-useable.I've since avoided updating my new one (due to the fear of having similar problems). I'm updating today, and I'm having problems. The process is not an easy one.I'm pc literate, and have built many pc's over the years, and know what I'm doing with hardware and software, but as stated already: "They couldn't have made map-updating more difficult or awkward."Such a pity.
