I purchased a 3,500km DMS map. It is registered and activated and works fine on my PC. I sent it from the PC using the MM software to my Adventurer 2800 but when I try to open it there it says that "The license for resource OS 1:25000 Explorer 2012 has not been activated". Clicking OK gives the additional message "Encrypted content is not available". Clicking OK then brings up an encrypted, unreadable map.
How do I activate the map for use on the Adventurer 2800?

The link below will give you the guide for the 2800. At the bottom of page 8, it describes activating maps on the SD card.

Thanks - problem solved once I knew where to look.
