A. To better manage your route archives, create a naming convention for your routes that includes key details such as date, location, or type of trip. This will make it easier to search for specific routes in the archive. You can also use the search function within the app to find routes more quickly.
B. Consider exporting your routes to a different format or app that allows for better sorting and management. If Navionics allows exporting to GPX or KML formats, you can use other mapping software to organize your routes more effectively.
