How Do I Update the Software on My Varia™ UT800 Smart Headlight?

If a software update is available for your Varia™ UT800 Smart Headlight, you will be able to install it one of the following ways.

Paired Device

A software update for your light can be installed from a compatible device such as an Edge cycling computer. When using Garmin Express to check for the latest software for your device, any available software updates will be provided for a previously paired Varia light. Once the controlling unit is paired with your headlight, the update will install automatically.

Garmin Express

To install a software update or to register your Varia UT800, you must have a Garmin USB ANT Stick and MicroUSB Cable. To update your software using Garmin Express:

1. Download and Install Garmin Express (see How Do I Install Garmin Express?)

2. Connect the USB ANT+ Stick to a USB port on the computer.

3. Connect the Varia UT800 to the computer using the USB cable.

4. Follow the instructions on the screen.

5. When new software is available, Garmin Express sends it to your device. Do not disconnect the device from the computer during the update process.
