I am very very new and very confused. I tried to figure it out and ended up deleting my Lakevu map off my sd card which sucks. I am trying to gget the North Cumebrland trails onto my device. However, I cannot get it to show up in basecamp. I believe I have the newest version of basecamp but I also get the maps are not unlocked either. I am about to go crazy..I cannot even get it to show up on the basecamp..any ideas of what to do? I have a Garmin Montana 680..

I have it installed. When I go to send the map to my device it says there are no unlocked maps were found for the device,,,

I have tried these tutorials but the map is not listed in the areas where I can install maps.

I am a super novice here with zero experience..I am trying to get the North Cumberlands map onto my GPS Montana 680 and cannot do it. It will not show up in Basecamp or anything..I know there has to be something I am doing wrong. Can anybody help me here?

Thanks
Nate
