Finding the Unit ID on an aviation device

The serial number is printed or engraved on every unit and is necessary for registration and warranty purposes.

The unit ID (or system ID) is an internal number which is required for database updates and downloads. (These updates can be done on our flyGarmin website.) Each aviation database update is downloaded specific to the system ID of each GPS, therefore if the system ID is incorrect on our website, your aviation databases will not update correctly.
