I see there is a map update via Garmin Express for my Nuvi. I try to install & get a message stating I need a SD card to install the lower 48- United States maps. I don't want to fool with an SD card & then try to get it to work correctly. I had seen in the past, I believe, on the Garmin Express App that I could install a map region of the United States. I have not seen this lately as I need only the South Eastern States. Any help on this or a possible workaround is highly appreciated.
P.S. I have, in the past updated this navigator successfully using same personal computer with Garmin Express
