Thread: Installed a map on a SD Card, but nuvi 2455 does not see it

I’m being able to see the maps on MapSource and transfer them to the SD card but when I look for the installed maps on the GPS, only the North America NT map is shown. I have already tried:

• Formatting the SD card to Fat 32
• Configuring the nuvi for Mass Storage (MTP Settings -> Mass Storage)
• Renaming the SD card to Garmin SD
• Installing the “gmapsupp.img” on the SD card on a folder named “Garmin” and I also tried naming it “Maps”

Help please!!

How did you unlock it in Mapsource?
Have you checked if in the sd is it unlocked?
Do you get an error message about that map when starting nuvi?
Folder must be "Map" not "Maps",not "Garmin"
