This is mainly for Highpointer, but anyone else interested in how to download multiple mapsets will be interested. 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.

If you have multiple MapSource titles installed, you know that in the pull-down menu just to the left of the Zoom In/Out buttons, you can alternate between them. Therein lies how to do it. 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.

Step 2. Pick the second title you wish to download map info from. Select each of those tiles using the Map Tool. You'll notice the names vary and in the Area column, the title chosen from is identified.

Step 3. Download to your GPS unit, keeping in mind the memory limitation. (I was able to download all of Arizona and Clark County, NV Roads/Rec, and a fair chunk of central Arizona Topo with plenty of room to spare).

Step 4. Once downloaded, go to the map screen. Enter the Map Setup screen and highlight the 'i'. 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. :)

There really isn't all that much to it, but figuring out how to make it work was certainly pretty cool. I was sitting about 100' from In the Cheap Seats today when it happened.
