Connecting Garmin Watch to iPhone 13 Pro Max

Hello LIONKINGWARRIOR,

Welcome to Apple Support Communities!

We want to help get your device paired to your iPhone.

We found these steps from the manufacturer to help you:

"Pairing Your Smartphone

To use the connected features on your watch, you must pair it directly through the Garmin Connect™ app, instead of from the Bluetooth®settings on your smartphone. 

1. From the app store on your smartphone, install and open the Garmin Connect app. 
2. Select an option to enable pairing mode on your watch: 

• During the initial setup, select Yes when you are prompted to pair with your smartphone. 
• If you previously skipped the pairing process, hold MENU, and select Pair Phone. 

3. Select an option to add your watch to your account: 

• If this is the first time you are pairing a device with the Garmin Connect app, follow the on-screen instructions. 
• If you already paired another device with the Garmin Connect app, from the  or  menu, select Garmin Devices > Add Device, and follow the on-screen instructions."

We hope this helps.
