My GARMIN 310XT does not show under devices on Modern view, I have downloaded and reinstalled both Garmin Connect and ANT AGENT - every time I go to devices it says that i need to download Garmin connect.
VERY FRUSTRATING:mad:
Just wanted to say that I experience the same problm even when I've switched to the new Garmin Express (instead of Connect/Ant agent). If it helps with troubleshooting I'm using Win7 and according to Garmin Express my device is up to date with version 4.50.
If you're using Garmin Express, you should fully uninstall the ANT Agent and Communicator Plugin. In addition, you should delete/rename the old Garmin folder in your {{%userprofile%\AppData}} folder. Once you do this, try pairing your device (you need to enable pairing in the device and then try to add a new device in the Garmin Express software).
Also, make sure that you are using Garmin Express version 3.1.9 or greater (3.1.9 is current as of this post) as it contains a specific fix for the 310XT which can occasionally work its way into a weird state preventing successfully pairing.
