How make lock Garmin Map unblock on SD?

Hi guys.

I wanted to add a map to my SD card recently and I came across "locked maps" on the Forum.

The Post that meant to teach me how to unlock them does not respond~? tutorials-f90/tutorial-how-install-gmap-folder-mapsource-basecamp-and-mapinstall-t4298.html

Any ideas how to do so? I am happy to PM anyone in private if needed. Cheers!

Case closed. Someone explained me how the software works.
