Not sure what happend but I don't have a premium strava account. But after messing around a bit I used to have my starred strava segments on the device.
But now they are gone...
In garmin connect training->segments I chose Strava segments, no segments are shown : just the screen saying "you are using strava segments, launch the strava app to view your segments..
On the device when I go to segments, it says 'No segments saved' Go to Garmin Connect at www.garminconnect.com to set up and download segments.
When I go to the garminconnect website under segments I can't seem to find how to add strava segments.
Any suggestions? This seems to be pourly documented.
