How do I pair and use my Garmin Varia or Bryton Gardia Radar?

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

Cadence is compatible with the Garmin Varia Radar‘s that supports Bluetooth Smart (BLE), which includes the RTL515RVR315, RCT715, and eRTL615 radar sensors. It’s also compatible with the Bryton Gardia R300 radar. When paired you will receive both visual and audio alerts on your phone warning you of approaching vehicles.

  1. Make sure to remove the rdar from any other apps or devices you’ve previously connected it to, including the Garmin Varia or Bryton Gardia apps, or it’ll continue trying to connect there first.
  2. Turn on your radar sensor
  3. Open Cadence, tap Settings, then Bluetooth Sensors, then “Add New Sensor”
  4. Select the found radar
  5. On the Bluetooth Sensors screen, you’ll now see the sensor listed
  6. Make sure you select the radar data (the number below indicates current vehicles detected)
