The settings here are for users with S-63 charts from PRIMAR. If you are using PRIMAR charts, you can enable occasional checks to see if you have any chart updates. When chart updates are available, you can download them directly from PRIMAR using an automatic download feature.
To use the remote update features from PRIMAR, you must have registered a S-63 user permit with PRIMAR that matches your S-63 User Permit or your Extra User Permit. You must select which user permit is registered with PRIMAR using the User Permit setting.
From time to time, you may wish to remove old update files in the PRIMAR Charts. After deleting such files be sure to do an Update so SEAiq can download any parts of those files that might still have been needed.
This feature will occasionally attempt to contact the PRIMAR update server to check on the availability of charts. This may involve using some of your cellular data bandwidth.
This capability can be used for your initial chart download as well as for periodic updates. For your initial chart download you may find it easier to download base or update zip files from PRIMAR: https://www.primar.org/enc-download.
You can see the status being updated as the download proceeds. When complete, you will get an alert.
Keep in mind that chart 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. If there is a problem during the download, the update will start again from where it left off.
