Trying to connect my watch to my iPhone. The Garmin Connect app can find my Forerunner 645 (I can see the screen with a 'Forerunner 645 Music Found' and a 'Connect it' button), but every time I begin the setup process the progress bar does not move and eventually I get the error message "Paring Failed - Unable to pair your Garmin device".
I have ensured I have the most recent phone/watch updates, restarted and disconnected both devices several times, restored to factory settings, but still no closer to connecting. Any advice?
