Updating the Software Using the Garmin Express Application
Before you can update your device software, you must download the Garmin Express™ application.
You can update the taillight software using the Garmin Express application. If you have the optional Varia™ RDU device paired to the taillight, software updates are sent wirelessly from the taillight.
Connect the taillight to your computer using the USB cable.
Garmin Express looks for software updates automatically and sends them to your device.
- Follow the on-screen instructions.
Disconnect the device, and turn it on.
The red LEDs progressively turn on to indicate the device is updating.
When updating the paired
RDU device, bring it within range (3 m) and turn it on.
The status LED on both devices turns purple to indicate the devices are updating. The update may take a couple minutes. When the update is complete, the taillight status LED turns green, and both devices turn off.NOTE: If you want to cancel the Varia RDU software update, hold the device key on the taillight for 2 seconds. You must pair the devices again to receive a software update.
