Anyone who goes off-road (or even into poorly mapped backcountry areas) knows that some roads and trails don't show up on all maps. For those instances, it could be helpful to be able to load custom routes / trails / roads onto the maps on the Rivian's displays. The usual file formats for this data are .kml .kmz .gpx and .geoson and therefore being able to import data from those file types (perhaps via the mobile app?) could allow this functionality. Bonus: waypoints can also be stored via these file types, so allowing import would allow importing waypoints as well
