  • Added HRV Support from chest strap for Yoga and breathwork.
  • Added pop-up to Pulse Ox Measuring feature if the device detects too much movement and cannot get an accurate measurement.

  • Added support for the snowshoe activity profile.
  • Added support for the tennis activity profile.
  • Added new tips to indicate which activities support Incident detection.
  • Improved accuracy of Surf wave count algorithm.
  • Improved Explore Sync app waypoint load times.
  • Improved Lactate Threshold and Altitude Acclimation algorithms.
  • Improved measurement loading UI when taking an SpO2 measurement.
  • Update the altimeter’s auto calibration to be either be “On” or “Nightly”. Setting to “On” will calibrate at night, activity start, and continuously during activities. Setting to “Nightly” will set the device to only calibrate altitude at night. (Models without DEM maps will not perform continuous calibration during activities)
  • Fixed issue with alarms intermittently not going off when the device is set in Max. Battery Mode.
  • Fixed display issues on the device after navigating to a point initiated by the Garmin Explore App.
  • Fixed issue where selecting a single point on a map that contained multiple items would not display the items properly.
  • Fixed issue that would corrupt open water swim activity files.
  • Fixed issue where PacePro bands would not be recognized by the device.
  • Fixed issue with updating aviation data over wifi.
  • Fixed issue with activities reporting incorrect Activity Calories and Training Effect data.

We know this post states it is a public release candidate, yet the URL states it's a beta.  This is simply a method of delivery for public beta.  We use the same channel and therefore the 'beta' term follows each of these links.  We only note it is a public release candidate so that you are aware it's the proposed version to go live to the public.  

  • I updated to 20.00 today (from 19.75) thinking that since it is a release candidate they corrected any battery and altitude issues. Version 20.00 is actually WORSE for me - it dropped 9% in 2 hours sitting inside at my desk. Altitude also dropped 500 ft during that same time period. I'm in the (painful) process of rolling back to 19.20 now.

    Did you try the fix someone posted in the 19.77 beta forums of fiddling with altimeter settings. So far mine's been stable. 

    And normally if you see this sort of battery spike, a quick off and on cures it 90% of the time

  • Yep, they can't wait. Same with the customer's, they wait in line to buy another Garmin , who will come with a unfinished software and live it's whole lifespan in a state of beta versions.

  • I know, I am saying that 2 days ago it did say 20.00 there, now it is saying 19.20 again, anyway, I can't seem to get what I mean across :-) 

  • it looks You can not read installation instructions.  You SHOULD NOT copy file from System_Backdate_1920!!! it contains rollback to previous stable release.

    But if You have 1920, only file from SystemUpdate_2000 is needed.

  • About altimeter... why they simply don't add a wifi calibration feature? In other terms: if smartphone is linked to a known wifi network, watch sets a determinate altitude,problem solved!

    No, not problem solved! A whole lot of other potential problems opened up.

    1) How do you verify the veracity of the altitude assigned to the WIFI point to begin with?

    2) How would this work in multiple story properties, you cannot assume the router is on the ground floor, it could be on any floor at any height.

    3) WIFI has quite a long range, so you could be several meters above or below that point.

    Those are just 3 ideas that came to me, and I haven't even had my morning coffee to fire up the old brain cells further...

  • Yes, but they can simply let u choose if enable or disable it. I'm sure that it could work for many people.

    Using DEM as a look-up table using the X and Y coordinates to find the Z value to assign to elevation should work. It's simple stuff - as long as you do it at the start of the activity with a good GPS fix.

    The fact that Garmin can't get this right is worrying, but it doesn't need other solutions. They just need to think about it a bit,.

    About 6 months ago I wrote that nightly calibration is a total broken flawed concept and it doesn't stand up to any scrutiny - I'd love an hour in the room with the engineers who white-boarded this and thought it was sensible....

  • DEM calibration is useless if you live at 23th floor...

    Why would you be starting GPS activities on the 23rd floor indoors? 

    Outdoors is when you want to calibrate, with a good GPS fix.
