Thank you so much for the quick reply. It leaves me a bit confused. I have always created two folders on the SD card: One named Garmin and the other named Map. I have the placed the gmapsupp.img in the map folder. For this Nuvi 765, I am to put the gmapsupp.img in the Garmin folder? Or, do I place the map folder in the Garmin folder? Sorry to be so flakey....I'm just getting older (well over 70) (not really a reason). Thanks so much.
PS: I've just now put the gmapsupp.img in the Garmin folder on the SD card and still no dice. The Nuvi 765 has been updated to software version 4.5 which is what Garmin Express is stating is the most current software. I'm doing something incorrectly, but I have no clue what.
I do note on boot up of Nuvi 765, for a nano second....the year 2012 is noted....but it flashes away and the map on the hard drive remains a 2009 version along with a 3d 2009 version. Am I supposed to do something to the file names on the hard drive of Nuvi itself??? Thank you so much.
