Radar Data Screen

WARNING

The device can improve situational awareness. It is not a replacement for cyclist attentiveness and good judgement. Always maintain awareness of your surroundings, and operate the bicycle in a safe manner. Failure to do so could result in serious injury or death.

NOTE: Before you can view the Varia™ radar data, you must pair the compatible accessory with your bike computer (Pairing Your Wireless Sensors).
You can add a radar data screen to remotely control your connected Varia RearVue radar device and view radar data. The radar data screen shows a graphical representation of the road behind you, as you are riding. Each icon 1 represents an approaching vehicle. For more information, see the manual for your radar accessory.
