When I tried it, I synced TR with Garmin Connect and then when you plugged the head unit it, it would sync the workouts to the Garmin. https://connect.garmin.com
Thanks, looks complex, as expected. I think I did all the steps right, but still can't access the workouts from within the unit, and it will only show me the scheduled one for the day.
I will try import a few as .fit files and see if that places them in the workout tab
Doesn't the TR app send them to Garmins?
