Hi,
I've a iPhone 6 with IOS 8.1 and my Garmin 620 don't connect by Bluetooth....
With iPhone 5 and IOS 8.0 the 620, it connects with the bluethoot regularly
Help me please
Same frustrating problem for me.
Changed my IPhone.
No Bluetooth connection in Garmin Connect App to my FR 620.
That didnt help:
I deleted the App (and App Data) from my iphone.
Reinstalled Garmin Connect mobile.
Entered my Login.
The FR 620 is listed in "Devices" without installation.
That helps:
I deleted the FR620 from http://connect.garmin.com/modern/device/.........
Open Mobile Version Garmin Connect on iPhone
Synchronize Devices (the FR620 should disappear)
Quit Garmin Connect App and restart the App
On the FR 620 Menu - Settings - Wireless - Connect Mobile Device (with a 4 digit Code in the display)
In the Garmin App Add Device - ... FR 620.
Bingo!
If the last steps don't work, its a good idea to quit an restart the Garmin App.
(Iphone 6 iOS 8.0 and FR 620 V3.0 ).
