Hi Guys,

I've a Garmin Nuvi 3750, and I'm doing all the steps. In the Mapsource I can see the map as "unlocked". I select a country (i.e. Italy) and then I send it to my memory card... It works ok! But when I put the microsd in the GPS and I turn it on, a message appears "Maps cannot be unlocked"... Can somebody help me? Thanks!!!! Cesar
