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
If using NavBox -> don't need to copy anything
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. We have made a FAT32 format utility available for download on the below link:
3. Copy INFO folder back to the newly formatted NavStick
If NavBox - insert in NavBox and send email to firstname.lastname@example.org in order to get it updated.
