Summary: I have owned this unit for a long time and the Topo! software for California as well. I do have the updated firmware for both the gps unit and the Vantagepoint software . I don't work for Magellan nor National Geographic. I link the unit to computers using xp and vista. At first, yes it took some getting used to working the unit with the two softwares (Topo! and VantagePoint).
Summary: I am a member of a K-9 search and rescue team and we use GPS devices a lot. This one for the money is just as good as the higher priced ones. The only problem I have is and it is just my own personal preference is it would be better with topo maps.
Summary: It was ok, can't seem to get it downloaded for the maps..so don't really have much use for it..tried for hours to download the maps,with no success...I would like to return it,but I have lost the receipt...
Summary: Nice compact design. Not much bigger than a cell phone. The buttons are a little hard to push, so your fingers get tired when manually entering coordinates. Navigation can be a little tricky if you don't read the owner's manual. Very accurate location pinpointing. Works well in light tree covering or semi-cloudy days. Overall good product.
Summary: I have only been using this item for a week but i enjoy it. Crystal clear display, it puts me right on my geocaches, easy to navigate through the menu, and it is already set up for geocaching. The only thing i would like it to have is built in TOPO maps. The basemap that comes with it isn't very detailed, mostly main US Highways and Interstates. But overall, for the price, its a really nice unit. I'm satisfied.
