I downloaded the 2017 map upgrade for my 93sv's that I bought at the first of the year. When I went to install them it read the maps, told me it would take a while, and when I hit yes it said there wasn't enough memory to do the built in map upgrades. I just upgraded from 3.8 to 4.1 a few days ago. Should I factory reset, upgrade the maps then upgrade the software or does anyone have another idea? It's a minor inconvenience but I'd sure like to have maps on the navigation chart.
