Resolved Question:

I have a nuvi 265w. I downloaded an unlimited free map update, which I bought a year ago. I downloaded a free map before without any trouble.
This time, the map downloaded, but a message says the maps are locked and I cannot use the GPS.

Can't unlock maps
Expert:  Andy replied 5 years ago.

Please keep the screen pressed using your finger when you see "No detailed maps found"
This message should go away in some time. And either there will be no message or there will be 'Cant unlock maps' message on screen.

Let me know

I needed your jump-start to get to the right place. I wound up loading 2013.10 (which was not available 2 days ago) instead of 2012.40, which I could not unblock. 2013.10 works fine. I have to believe that Garmin had a bug in my first download. Thanks for your help. It was worth the $30.
