Format Nav Directories
Settings: Press RIGHT Cursor key and follow screen
instructions.
Use this menu choice with caution!
Format Nav Directories deletes ALL navigation data (waypoints, routes, tracks,
and groups) and resets the navigation data directory in the Waypoint
Management dialog box. You may need to reset the navigation directory if
you’ve imported corrupted navigation data from an unknown source, which can
cause the unit to malfunction (see SD Memory Card Slot: Import Navigation
Data). Contact our Customer Resource Center before using this menu option.
NOTE: It is important to back up your control head’s data files periodically. Data
files should also be saved to your PC before restoring the unit’s defaults
or updating the software. See your Humminbird® online account at
humminbird.com and the Waypoint Management guide.
