I have one and just used it for a trip out West; Eau Claire, WI to Spokane, WA. I got the latest version of the MapSend Topo USA software and a 512 MB card and was able to put in a 247 MB region that covered western Wisconsin, the northern 3/4 or so of Minnesota, most of North and South Dakota, most of Montana, northern Wyoming, the northern 2/3 of Idaho and eastern Washington. The roads and highways seemed pretty up to date, I could locate restaurants and hotels in my vicinity, and the topo mapping in the mountains was exceptional. I recently factory upgraded my Magellan Meridian GPS to the Magellan Meridian Gold, as well as the upgraded to the new MapSend Topo USA software and I am happy I did. Can't wait to use it in the field this year.
