hi i had the same problem where it could not unlock the map on a garmin Colorado 300 and a 4gig card
when i checked the properties of the password file it was actually a gmapsupp.unl.txt file
you need to copy the key in the file, delete the file then use notepad to create a new file called gmapsupp.unl **make sure you have save as type' all files' selected or it will not work.*****
once it is created do not open it again and save it or it could change it back to a txt file even though it says gmapsupp.unl in the save bar.
make sure it is in the same directory as the map file (usually in a folder named garmin on the memory card.)
click on its propities again and make sure it does not show it as a txt file
after i did this map worked first time )))
