I was struggling to find help to connect my myzone HRM to my Garmin.
I’ve figured out how to do this so thought I would post a blog for anyone else having these issues.
First things first you cannot connect a non garmin device (such as a HRM) to garmin connect.
You can however connect it to your watch. Now there is a blog stating you can do this but not how.
For my watch vivoactive 5 you have to hold the B button to find the settings>accessories. From there you select add new (ensure the accessory is on) and the watch will search for the device.
This shouldn’t take too long. If it takes more than 2 mins, which mine did, I had to turn the watch off then on and follow the steps through to pair the HRM.
For your own individual watch I’d recommend looking at the garmin manual to find the settings option and you should be able to follow the above steps.
Hope this helps
Here is the garmin manual I have for my watch
