I attempted an update to my Garmin 2460 for USA full map. Everything went well until I tired to access the map on the Nuvi. It had DL'd but was not recognized by the 2460. IN checking the amp under tools, there are no entries. The manual suggested installing SD micro ship. Installed and dld map dl to card, Nuvi will not recognize map on card It does recognize the card under pictures as as a Put on pic on the card to check that. None of this has worked so far.
Own Nuvi 2460. No previous problems.
