Updating garmin 760
Garmin Nüvi 760 drivers are tiny programs that enable your GPS hardware to communicate with your operating system software.
I clicked on reinstall and full coverage of North America came up as a choice and started immediately.
I can't figure why it didn't give that option in the first place.
My nuvi 750 should update to SD identically to your 760 and at the last update (2013.40), I was able to install all of North America to a 4GB SD card.
I see that the map image file is almost 1.9GB* in size so a 2GB card is really flirting with disaster and unlikely to work with the 2014.10 map due out next week or so.Long story short--repeat the update using Garmin Map Updater rather than Garmin Express and report back.
