I have one 8 GB card in my 66sr containing a France Topo. map, and another 32GB SD with Topo maps of Spain and Italy. How can I move the France map to the 32GB SD card ?
Depends what the cards are and how the maps got there. If they are a genuine Garmin product they are locked to the card, so cannot be moved. If they were freely obtained third party maps then it's just a question of moving the map files. Need more detail about the cards and maps to give accurate advice.
If so they are probably locked to the device, can you recall being told that when you downloaded them? If so simply copying the map files from the France card to the other one should work, There should be three files, the main map file will be a .img file and there will probably be two other files, a .gma file and a .unl file. There may be more as I don't have the France topo map to check.
