Edge 830 not calculating VO2 Max

I replaced my Edge 820 with a new 830 back in June and since then I haven’t got a single VO2 max update, I ride with vector 3 power meters and garmin HRM band. With the 820 I used to get regular VO2 max updates but now even after 1400km ridden I still don’t get it. One detail that could’ve influenced it is the fact that at the same time I started using the edge 830 I also started using a vivoactive 3 watch. The watch seems to be able to calculate vo2 max on my walks for example.

  • Do you see power and heart rate values logged in the activities logged by Edge 830?

  • Hi, yes, HR and Power values are all present in the activities logged by the Edge 830 and they all seem correct/consistent. 

  • I suspect a mishap with the account-device association when you added the new watch. Is the new watch set as your preferred activity tracker? Is Physio TrueUp enabled on all your devices, and do you sync all devices before and after each activity?

    If that is all right, then I suggest removing all devices from your Garmin Connect account, signing out of the app, signing back in, and adding back the devices you still use. You may need to repeat it with other Garmin app you use, including Garmin Express and Garmin Connect Web.

  • Hi Trux, thanks for your input, indeed that's my setup, the watch is the preferred activity tracker but that option can't be changed as far as I can tell, I tried with Physio TrueUp on and off but didn't see any difference. In your opinion, is there any specific order I should follow while re-adding the devices?

  • Yes, having the most active watch as your preferred tracker is all right. As for the order, try following the instructions in this document: Garmin Connect Sync Issues Due to Having Two Accounts | Garmin Support Center 

    Do not forget to sign out, after removing the device, and then signing back, as written in the paragraph under the individual steps!
