Per mia curiosità ho generato lo stesso percorso su MRA impostando Garmin ed il file .gpx è questo:

A me sembra che non ci siano altre istruzioni se non quelle di Route (cioè i primi 2 WP all'inizio del file) e a seguire quelli di Track (cioè la traccia, quella miriade di coordinate che seguono).
Intendo solo dire che il casino per me nasce solo dal fatto che impostando Garmin (o TomTom) che non hanno mappe dettagliate dell'area la TRACCIA generata ovviamente non è attuale e quindi non utilizzabile.
