Just as a point of interest, once the map is loaded, the 1390 allows it to be renamed as anything.IMG and it will still read it, and so you can load up as many maps as you want. I have Australia, Argentina, Chile, Brazil, Bolivia, Peru, Ecuador, Colombia and Central America all loaded at the same time. You can go in and uncheck the ones you don't want at the time, or load them if you want to add waypoints in advance of your trip.
