Summary: It's a nice GPS but I should have studied the mapping characteristics better. The GPS came without detailed maps-- I bought topo maps for it that should work but after spending about 10 hours trying, I'm still stumped. Information on the Internet and the Magellan website (210 is unsupported) suggests the problem is with the serial number not being recognized by the map-- at any rate, putting a topo map on this thing is ruined what might otherwise be a good deal.
Summary: This receiver would be acceptable except for the following: the interface connector is awkward to use, as well as the battery compartment access. The unit eats batteries like Popeye eats spinach. Even when the unit is turned off the batteries are rapidly consumed. The software is incredibly slow. Accessing track information, for example, typically requires about one minute (I've timed it several times), whereas other receivers retrieve this information almost instantly.
Summary: The GPS works fine, but I bought this unit because of the software available that it was supposedly compatible with. Do NOT purchase this unit if you think it will work with any of the mapsend programs. It will NOT work. I have spent 3 days of sending emails and making phone calls, and cannot get any support from this company whatsoever. I still have yet to load topo map one into this gps. With no releif in site.
