Cananda and Mexico unlocked maps are not recognized on my Nuvi255WT. Yes, I have them installed on SD card>Garmin folder. Named "gmapsupp.img" and "gmapsup2.img". I tried just adding one file - nothing. Rebooted.
Settings>Map>Map Info - only map that shows is the one on my Internal card "North America 2010.30 unlocked"
I even copied over the original map that came with my 255WT (2010.10) onto SD card and it did recognize and display it fine in map info (both maps appeared with checks). So I know I am placing it in right folder and naming it correctly.
Do these Cananda&Mexico maps not work with Nuvi 255wt?
