Using Garmin Update, I decided to update my nuvi 255w to the new 2013.2 North America map. When I tried to do this, I received a message that there was not enough room for the whole map so either insert an SD card of sufficient size or update to a smaller map. I chose the 49 state map.
I now have purchased an SD card (16 GB), and wish to get the entire North American map. Firing up Garmin Update, I find no such option. It did give me an option to "reinstall", but only the 49 state map.
What do I need to do to install the complete 2013.2 North American map?
