I suppose a somewhat obscure problem but just me thinking ahead.....\n\nFor my Garmin Drivesmart 51, which came installed with "lifetime" Europe map(s), I also bought a USA map which is installed on the SD card of the device.\n\n2 questions really.\n\n1. I'm about to create waypoints and routes within Basecamp, using the SD copy USA map, for a forthcoming USA trip. It will be quite a lot of work which is all part of the fun of planning our trips. But I don't want that fun to dissipate when I update that USA map before our trip, should Basecamp and/or the Garmin 51 then not be able to use those POIs/Routes with the new map. Any advice on that, please?\n\n2. I read somewhere that, if Basecamp shows a map as being "unlockable" in "Maps, Manage Map Products" (which it does for the USA map) it should be possible to copy it to PC for Basecamp planning purposes. But that does not appear as an option when I go into "Maps, Install Maps". Only the Europe map is copiable to PC.\n\nAll advice welcome, thanks!
