Hey guys,
i read that many users have issues in the last days with connecting their watch to their iPhone. I had the same. I removed the watch from the 'Garmin Connect' app and tried to link it again. Unfortunately it didnt work in the beginning but after some research i finally found a thread from 3 years ago that fixed it for me:
Solution
From Garmin Connect Mobile app on your iPhone
- Tap "More" >> Garmin Devices >> Select your connected device
- Tap 3-dot icon on the upper right >> Remove Device >> Remove
- Close the Garmin Connect Mobile app
Go back to the main menu on your iPhone
- Open Settings >> Bluetooth
- Under "MY DEVICES" tap the "i" icon to the right of your Garmin device
- Tap "Forget This Device"
- Restart your iPhone
Open the Garmin Connect Mobile app
- Tap the "+" icon in the upper right
- Select your watch from the list of Garmin devices
- Put your Garmin watch in Bluetooth pairing mode (This varies based on device. Check your manual)
- Tap Start on the app and the iPhone
- When prompted with "Bluetooth Pairing Request" enter the PIN (passkey) displayed on your Garmin device
- When iPhone displays "Pairing Complete!" tap "Done"
Everything is working fine for me again.
Hope I was able to help!
