I use 'gimporter'' ConnectIQ widget in my Fenix 5x and in my mobile 'GPX/FIT exporter' companiun app. Really easy. https://apps.garmin.com/en-US/apps/fac50ef3-77b2-466c-9f4f-4dcb2feb49a3#0
After installation of both:
Just download as a fit file to your mobile. Tap on the downloaded file and you get the option to open it with GPX/Fit exporter.
Open the gimporter widget. Press start. Select the file with start and you are ready to follow your course.
I'm traveling and don't have access to a computer. I am reconning, making changes, and need to download modified routes to my Garmin Edge 830 and 1030.
