I don't know if you already have got this Map for Garmin: it's my first post, i didn't find it in the forum.
Installation guide
1)extract all files to grmamnt.txt
2)rename grmamnt.txt to grmamnt.zip and extract again
3)Burn all files to DVD if you like to or Navigate to Windows\CNNANT2009Update_ENU.msi
Wait for installer to finish.(you must run it from there otherwise will ask for previous version to overwrite it)
4)Create yourself a key for Mapsource using the Map ID: 325
Load new maps to your GPS.
Here it is a .torrent file to download an unlocked version

Thanks to Fervex for the .torrent
