One is the New England topo and the other is My Trails. I believe the New England Topo was down loaded from this site. Less sure about "My Trails". IT seems to be some sort of overlay that you put on top of an existing map.
I have not used maes from here as a while. I got a new gps and moved my memory card into it. MY old GPS File DEpot maps show up on my map list, but the two I just loaded do not. The maps I tried to add are on the memory card as I can see them in File Manager. My GPS gives me a message "Cannot unlock Maps" on start up.
