I have & use a legend also. I have the Mapsource Road & the Topo CD's. When you load a new series of topo maps into the unit it deletes whatever maps are stored in the unit. I currently have about about 1/2 of Arizona loaded into mine. Keep checking on Garmin's Website for updated software for your Legend.
Thanks 250RDUDE, but when I load a local map will it delete the low detail map of the U.S. Legend came with? (you know how the legend came with a map of the United States showing highways and major roads). Will this be deleted if I load a detailed map of florida. Will I still have the highways for the rest of the U.S. after I load a detailed map of part of Florida?
Thanks for your help DUDE.
