  • Although this software is believed to be reliable, it has not yet been released for production and should be used at your own risk.

Changes made from version 2.50 to 2.64:

  • Added ability to enable wrist-based heart rate for swimming (pool and open water). To enable this feature: 1. Open Menu 2. Scroll to 'Wrist Heart Rate' and enter menu 3. Scroll to 'While Swimming' and toggle to 'On'
  • Note that there are inherent limitations with the technology that may cause some of the heart rate readings to be inaccurate under certain circumstances.   These circumstances include the user’s physical characteristics, the fit of the device, and the type and intensity of the swimming.  For the most accurate heart rate during swimming, Garmin recommends using HRM-SwimTm or HRM-TriTm heart rate monitors. 
  • Added Connect IQ 3.1 functionality.
  • Fixed issues with LiveTrack
  • Addressed rare issue of hourly alert drifting off of hour
  • Fixed lapping issues in adaptive training plans and workouts
  • Addressed 'Around Me' search time when using North Up map
  • Fixed issue of duplicates of a user in GroupTrack
  • Enabled support for Approach CT10 golf club trackers
  • Added Sight N' Go feature
