I just bought Topofusion yesterday and It's great stuff!. I have Maptech but it won't support Magellan Explorist. Well, I ran identical tracks with my Etrex Vista and my Expl.500 today. Ran both on TopoFusion very nicely. While in Topfusion I saved my Explorist track with a Maptech track file ext. in a Maptech track file. When I went into Maptech I imported the track file and lo and behold it worked in Maptech. Wow this is going to save alot of folks. I really like the product, but the print option needs to be expanded upon, really.
