When I plug the first micro card into my computer it will show me all the map file names on the card. When I plug the second card in the computer it will show me that gsmapp.img file and nothing else. The first card has the same maps as what i am trying to load on the second card. I guess what i am trying to say to make it easier is that I am trying to load maps from basecamp on to my sd card and It wont load to the sd card. The only thing it loads is this gsmapp.img file which I have never seen on my cards before when loading maps.
