MARK Key

Press the MARK key while in any view to mark the position of a waypoint. The
MARK key function is available if the GPS receiver connected.
• Active Cursor: The waypoint will be marked at the cursor location.
• Without Active Cursor: The waypoint will be marked at the boat location.
• If Screen Snapshot is active, a waypoint will be created, and a screen snapshot will
also be saved to the optional-purchase SD card (see Views: Snapshot and Recording
View). Navigation is not affected by the Screen Snapshot feature.
NOTE: If Screen Snapshot is enabled but there is not a GPS receiver connected, pressing the MARK
