You need to use the "Map Tool" in MapSource, which allows you to select map segments from the main window. The Map Tool can be selected by selecting Map from the Tools menu (Tools-->Map), or you can make sure the Tools toolbar is showing (View-->Show Toolbars-->Tools), and then select the Map Tool from the Tools toolbar. Now you can choose the map segments that you wish to load into the GPS. The map segments you select will be highlighted in the main window, and the map segment's name and size will be under the Maps tab window on the left side of the screen.

Never saw any response by someone who actually used your code and instructions to create these larger segmented Topo maps that could all be downloaded onto a 2GB card and used in the GPSr. I used your routine last week and it worked like a champ. When looking around for a way to solve this problem, I found your post and this one: http://www.groupsrv.com/science/post-2197256.html I tried both approaches out a little over a week ago. Running at the same time, it took about 48 hours for them both to complete. The other method mentioned above "seemed" to complete OK, but when I checked out the map segments in the GPSr, many of them were not available and I think this is probably due to the GPSr addressable map segment limit. However, with your methodology, I have the whole Topo US map set available in my GPSr. Thanks a bunch for making this available. It worked great for me. Russ
