Hi there - I'm having a few problems syncing my Edge 500 on Garmin Express. My device charges without any problems via the USB but new activities won't sync on Garmin Connect or Strava and I have to manually upload from the file. It also won't let me send a course to my device. I get an error message saying, "It looks like there isn't an ANT Stick connected." Any ideas? I have never had any problems until Garmin Express came along.
