How do I pair and use my Garmin Varia Radar?

Connect your Garmin Varia just like you would any other Bluetooth BLE sensor!

Cadence is compatible with the Garmin Varia RTL515 and RVR315 radar sensors because they support Bluetooth BLE connections. When paired you will receive both visual and audio alerts on your phone warning you of approaching vehicles.

Make sure to remove the Garmin Varia from any other apps or devices you’ve previously connected it to, including the Garmin Varia app, or it’ll continue trying to connect there first.
Turn on your Garmin Varia radar sensor
Open Cadence, tap Settings, then Bluetooth Sensors, then “Add New Sensor”
Select the found device that begins with RTL or RVR
On the Bluetooth Sensors screen, you’ll now see the sensor listed
Make sure you select the radar data (the number below indicates current vehicles detected)
Optionally turn on Audio Alerts
On the main Computer screen, you will now see a visual indicator on the left side of the screen.
