I bought a Garmin Topo map (Topo Southern Africa 2013 PRO) and it came on a SD card. I want to install this on my PC (Win 7) to do route planning etc. on Mapsource or Basecamp, but it seems that it will only run with the SD card inserted. I do not appear to "install" the maps onto my PC so I do not have to plug in the card each time. Is there any easy way to install the maps to my PC?
