This software update can be downloaded by using Garmin Express. Please note that once a software update is released it can take up to 24 hours before Garmin Express provides this update to all users.

Changes made from version 3.10 to 4.10:
  • Added support for Varia Vision. Pair with this sensor by turning it on and going to Settings > Sensors > Add Sensor > Varia Vision. Choose it from your list of sensors to configure its display settings and data screens.
  • Improved stability of ANT+ sensor and Bluetooth connections to address dropout issues.
  • Added the ability to automatically download software updates over Bluetooth. You will be able to download the next software update after this one by pairing to a smartphone and connecting to the Garmin Connect Mobile app. Updates can be installed when you are prompted after they download. If you choose to wait, updates ready to install can be found in Menu > Settings > About > System > Software Update.
  • Fixed an issue causing some manual activity uploads over Bluetooth to fail.
  • Fixed an issue causing GPS to be enabled on the 'Indoor' profile after a power cycle.
  • Fixed an issue causing course point information to appear with the 'Course Points' toggle turned off.
  • Fixed an issue preventing the device from transitioning back to the correct data page after showing segment prompts with the map disabled.
