I received an Edge 520 Plus for Christmas, and thus, finally replaced my old Edge 500. Since day one I’ve had nothing but fits trying to get the 520+ to sync and auto upload properly. My devices are:

Edge 520 Plus
iPhone 7
Garmin HR strap (not the premium one)
Giant onboard Ride Sense for Speed and Cadence

I’ve been working with a Garmin tech via Email for almost 2 weeks now to try to resolve these issues. So far I’ve deleted and reinstalled Garmin Connect app on my phone, done numerous checks to verify settings, but still I’m having issues. Syncing with my iPhone seems to be hit and miss. The 520+ required 2 BT connections which was a bit confusing at first.
Also, my riding partner has the same Edge 520+ and when he saves his ride, it instantly uploads to Garmin Connect and Strava. He swears that he doesn’t have to open his Garmin Connect app either. I am struggling to understand how this happens since the Garmin tech tells me that I have to open the Garmin Connect app for this to happen. Even when I do, I still have to manually start the sync process, even though I have AutoSyc enabled.

I’m wondering if anyone else has experienced these issues, and has been able to resolve them? If so, please tell me how you did it.

Thanks,
Ray K
