Looks like I just wasted US$ 160 down the drain. Bought a Norwegian 20K Topo map as a SD card. Today I put the card into the SD slot and would like to save the map to the Montana 700i using Bascamp/Express. Due to Garmin Copy protection it is not possible to move/copy the SD card content.
Only way to save the the 20K Topo map to the unit, or a 32GB card, is to buy the download version, not by buying the SD card version. Should be a warning telling you that the SD card version is not possible to move/copy to the unit.
