My garmin GPS, H model, as pictured in the post "108 kph with 1.8m sail'' won't download. 3 of us have spent 8 hours or more using different computers, getting updates, all over the googling garmin sites to no avail.The GPS works fine for displaying on its screen the max speed, speed, odometer, etc, but won't connect to a computer. The same model, a different one works fine. Have tried everything. Someone must know how to do it. Maybe its f#*ked! Help needed.
