Pairing DURA with Garmin Varia Radar & Tail Light

DURA supports pairing to Garmin Varia and other radar lights via ANT+ to alert you of approaching traffic.  To pair with your Garmin Varia, follow the steps below:

  1. From the main menu, scroll to System > Accessories > Add Accessories. DURA will begin searching for nearby ANT+ devices.
  2. Make sure your Garmin Varia is powered off. Then, press and hold the device button for 2 seconds. A purple light will begin flashing, indicating the device is in pairing mode.
  3. When your Garmin Varia appears as a nearby tail light, select it on DURA's screen to complete the pairing process.

With your Garmin Varia paired, you can customize the following settings directly on DURA:

  • Tones: ON or OFF.  When tones are toggled ON, DURA will alert you at the following times:
    • Three beeps: when Varia detects that traffic is approaching at high speed
    • Two beeps: when Varia detects that traffic is approaching at normal speed
    • One beep: when Varia detects traffic has safely passed
  • Mode: Auto or Custom. With Auto selected, your radar will use its default light setting (alternating steady light or flashing light, depending on approaching traffic). With Custom selected, you can control the light pattern with the physical button(s) on your Varia. Varia will remember your chosen setting each time it reconnects.
  • Check your Varia's battery level
  • Check your Varia's software version

Using DURA and Varia during a ride

Once your Varia and DURA are paired, they will connect each time you record a ride.  On the start page of your selected bike mode, make sure the small radar light icon stops flashing and turns solid (indicating a full connection) before pressing Start.

During your ride, a small radar light icon is displayed in the top right corner of all your data pages.  When Varia detects that traffic is approaching, DURA will alert you both visually and audibly, via a sidebar overlayed on the right side of the screen along with tones to indicate the threat of oncoming traffic.

  • Red sidebar and three beeps: Traffic is approaching at high speed
  • Yellow sidebar and two beeps: Traffic is approaching at normal speed 
  • Green sidebar and one beep: Traffic has safely passed

Tones can be disabled by going to Accessories > Varia tail light > Tones > OFF.  This does not impact the visual cues from Varia that appear on DURA screen.

How can I view the battery level of my connected radar light?

View the battery level of your connected radar light by going to System > Accessories > select your device.

You can also view the battery level in real time during activities.  To do so, set up your DURA data pages ahead of time.  See our article Customizing Activity Data Pages on DURA for detailed instructions on how to do so.
