The settings here are for users with charts available from a File Transfer Protocol (FTP) server. This will make the initial download of charts and then periodically check for updates.
From time to time, you may wish to remove old update files. After deleting such files be sure to press Update so SEAiq can download any parts of those files that might still have been needed.
This capability can be used for your initial chart download as well as for periodic updates.
You can see the status being updated as the download proceeds. A notification is given when complete.
Keep in mind updates can be quite large. You may want to wait until you are connected to a high speed internet connection before downloading updates for your charts.
This may be useful when changing accounts to clear out old files. Also, we recommend doing this periodically to reduce the number of update files present on your device.
