Need help. Can't update my navigation software

As andrius wrote - make sure you have no subfolders on your usb stick. Unfold the raw files inside your current map to the root.
Also make sure you have a valid fsc code loaded to your car for the update, as you cannot update without a valid fsc code.

Thank you for your advice. How i can double check, if i have a valid fsc code loaded on my car for the update? How i can get a valid fsc code? Best regards,
