Hello!

I've been trying to update the map on my Garmin nuvi 650 using the "gmapsupp(9147)NA.rar" file provided by "City Navigator North America NT 2022.20 FID 9147".
I've formatted my USB as MBR FAT32 and placed the "gmapsupp.img" file under the Garmin folder that I created. However when I place the SD card in the GPS and checked available Maps, only the outdated built in one shows up. I've updated the firmware to the latest version using Garmin Express. Also according to what I've read on the forums this model doesn't require unlocking the firmware either (I'm guessing the maps are already unlocked).
I'm not exactly sure what I'm doing wrong here and would appreciate any help. Thank you.
