Summary: Have had the unit for a month. The screen resolution is absolutely the best I have seen. I can read the street names without using my reading glasses. Have not had an opportunity to use many of the features as it may take years. Several disappointments with the unit. It is not capable of feeding Lat and Long. data to a laptop as did my old Garmin Street Pilot. It also advertises over 3000 lakes worth of navagation charts on the unit database.
