If you have a Linux based chart/radar unit, you need to have NavStick with filesystem FAT32.
(Typically Olex, SAM ChartPilot, Furuno FMD)

If using NavSync to update -> Copy INFO folder from NavStick to harddrive

2. You need to have special format utility in order to format your NavStick using the FAT32 file system. The reason for this is that your NavStick is 64GB, and the built-in format utility in Windows only supports formatting FAT32 drives up to 32GB.

3. Copy INFO folder back to the newly formatted NavStick

Perform NavSync
If NavBox - insert in NavBox and send email to technical@navtor.com in order to get it updated.
