A few weeks ago, there were some posts about the viability of downloading more than one mapset for simultaneous usage/storage on Garmin units.  To my knowledge, and scouring instruction manuals, it wasn't possible.  But through some trial/error, I figured it out.

Keep in mind that each unit has limited memory, you'll need to be aware of your available storage as you pick maps.  Watching on the Maps tab is a good idea as it tallies your chosen map blocks and their respective sizes.

This screen brings up the map tiles along with something to identify them, such as Topomap for the topo files.  From what I could gather, Roads/Rec was listed first and was the primary mapset used.  In order to reveal the other mapsets, you need to begin unchecking the other mapsets you don't wish to see.  In theory, with enough memory you could have something from every single piece of Garmin map software available in the field.  Doing this is simple, and I had no problems switching between 2 titles on my Vista while sitting on the side of a mountain really wanting to see the Topo for the area.  :)
