Saving user data
You can backup your user data (waypoints, routes and tracks) to a MicroSD card.
The LightHouse 3 and LightHouse 4 operating systems allow multiple waypoints to be created with the same waypoint name. If you intend to import the saved waypoints to a different system ensure that all waypoint names are unique or that the system you are importing them onto supports non-unique waypoint names.
Example: If more than 1 waypoint with the same waypoint name is imported into a LightHouse 2 MFD only 1 waypoint with that waypoint name will be imported as the LightHouse 2 operating system requires waypoint names to be unique.
The user data file is saved to the ‘\Raymarine\My Data\’ directory of your memory card in gpx format.
