I purchased 2 Garman Rhino 530 HCx a couple years ago and the Topo U.S. set to down load.....interesting to visit places before you get there. I'm not much of a gadget guy, but last summer as I was planning a trip to the Trinity Alps wilderness, it was fun to get an idea of the projected highway route and sites to take in along the way....turned out to be a good trip.. after 20 days in the Alps, we even took in the Redwoods and a little California Pacific surf before heading home.....hadn't been there since 25 years before.....good to go back to another place and time once in a while ;D
