I'm a novice of the Fenix6X Pro, but I have a long experience with various Garmin devices.
I made a track with Garmin Connect and imported it on the Fenix.
By starting the activity and Navigation using the loaded route, turn-by-turn navigation only shows me the direction arrows and not the map thumbnail with the turns.
Always with the same activity and starting the turn-by-turn navigation to a POI or to a point on the map I see both the turns on the map and the meters that are missing.
What haven't I done?
