i'm trying the SD card too.
I deleted the file PRODUKT.NDS in the root Garmin/NDS/PRODUCT
Then you do not get the message"can't unlock the map".
Then i deleted the file PRODUCT.NDS in the root Garmin/NDS/PRODUCT2
and you can see the Folder Europe v2.3 in the settings of the Navigation.
But i can't open it and i don't know if it's possible at all.
