What is your OS and where have you placed the gmap folder?
If you're running Windows, MS will see it if you've got it placed like this:
XP, in C:\Documents and Settings\All Users\Application Data\GARMIN\Maps
Vista & Win7/8, in C:\ProgramData\Garmin\Maps
It will display it even if you haven't unlocked it, you just can't select tiles if it's still locked.
