Garmin Forerunner 45 – Connectivity Issues

After having had quite enough with the Polar M600 and its connectivity issues with iOS, I decided to go and buy a different smartwatch. I do have a few non-smartwatches (or watches, if you may) that I use, but since their straps are breaking, batteries are dead, etc, none of them are quite ‘wear and play’ either. Anyway, a lot of research pointed me to the Garmin Forerunner 45.

My requirements were simple, I wanted a fitness watch primarily, which had a heart rate monitor and had GPS built-in, so I didn’t need to carry my phone with me while I went running or did other exercises. Notifications are okay, but not really needed, though an indication of when my phone is ringing would be useful. What I wanted the most was a good fitness app and something that had a reliable connection. The Garmin Forerunner 45 ticked all these boxes. I will be doing a thorough review soon, so keep your eyes peeled.

Sadly though, the Garmin Forerunner 45 still has some connectivity issues, though it is a lot easier to deal with them than the Polar M600.

Dealing with the Garmin Forerunner 45 connectivity issues

So, after having this for over a week, I find that almost once every 24-48 hour period, the watch loses its ability to sync with the phone. Weirdly, it still delivers notifications, and the phone icon on the watch is still there, but it just doesn’t sync. Sometimes, the phone will also say that it isn’t connected, which is at least better than it pretending when it isn’t.

It must be mentioned that these issues are found only on iOS so far, and I haven’t tried the watch yet on an Android.

I found the following worked best for me:

Restart the watch

The easiest way to get the connection back was to restart the watch. To do so:

  • Hold the LIGHT button for a few seconds till you go to the circular menu.
  • Using Up/Down keys, scroll to POWER OFF.
  • Press Start||Stop to Select, and the watch will turn off.
  • Give it a couple of seconds, and then hold the LIGHT button for a few seconds till the Garmin Logo (the triangle) appears on the screen.
  • Once your watch has booted up in a few seconds, you will find that it will show the phone disconnected logo, followed quickly by phone connected logo.
  • Now your phone should be able to sync with your watch, and that can be done via the phone or the watch.

I turned it off, but it won’t come on

Oh yes, I had a little panic moment with the Garmin Forerunner 45 when I turned it off, and then it just won’t come on. It was brand new, and I really didn’t want a broken watch on my hands. Luckily, I found a way around it.

  • Turn watch off, as per instructions above.
  • Try the LIGHT button, and panic as it doesn’t come on.
  • Connect to Charger, as breath a sigh of relief as it does.


Since the last few firmware updates, the problem has mostly been fixed.
