So, something to consider. Roads and Rec has some decent detail and shows a good deal of roads, however, if you are going way off road, you will want topo for the terrain detail. As far as the downloading of maps... each time you download a new mapset, you loose the old one. So, if you have a mapset of the entire state of Arizona downloaded into your Vista and you want to, say, add the SW corner of New Mexico (or wherever), you will loose the Arizona mapset. To add that SW corner of New Mexico, you have to create a new mapset that will cover the entire state of AZ and that one SW corner of NM map. So, when you had Mesa West in there and you went to add Phoenix South, you lost Mesa West. What you should have done with loaded Mesa West with Phoenix South. On another note, if you want to return to the basemap and drop all your mapsets... you just do a map download to your GPS with a blank mapset (no maps) and it will delete all the maps in your GPS and put it back to the original basemaps. On yet another note.... I got the new Garmin 60C... it does use a USB and it does download maps MUCH faster than the old serial port connection.
