MicroSD card
The GPS reads microSD cards of any size in FAT32, ExFAT and NTFS file systems, though, TwoNav will only look for maps on the microSD card (no tracks, waypoints or other types of files). It is recommended to install the maps at the root of the card instead of creating subfolders
NOTE: Mac computers don’t allow writing to NTFS drives. If you have a NTFS card and want to install maps from a Mac OS, you must format the card in FAT32 or ExFAT format.
