On Oct. 17th it performed a "sensor hub" update, after which the barometer/thermometer sensors stopped working. The altimeter now never changes. The altimeter calibration fails. The barometer reads 83886. The thermometer does not show any value.

If you are experiencing this issue, you can backdate the Sensor Hub software on your watch to version 3.00. If you'd like to try this, here are the steps:

1. Download the .GCD file attached to this post
2. Connect watch to computer
3. Open the Garmin drive
4. Open the Garmin Folder
5. Open the RemoteSW Folder
6. Place the .GCD file into the RemoteSW Folder
7. Edit the name of the .GCD file to remove "_force" from the name
8. Safely eject the watch and power on
