Product Information

Full details

The Garmin Varia RearVue 820 is for cyclists seeking enhanced awareness and safety on the road. Its key benefit is providing powerful radar detection of approaching vehicles and a highly visible tail light, significantly reducing the risk of collisions. A potential caveat is its reliance on compatible devices or a smartphone for full functionality. This radar tail light offers robust vehicle tracking up to 175 meters away with a wider field of view, features a bright tail light visible up to 2 km, and includes a brake light for added safety.

Troubleshooting

Varia not detecting vehicles

Ensure the Varia is powered on and paired correctly with your head unit or smartphone. Check that the radar is not obstructed and that the firmware is up to date on both the Varia and your display device. Verify that the radar-on mode is enabled if using radar-only mode.

Tail light not illuminating

Check the battery level and charge the device if necessary. Ensure the light is enabled in the Varia app or on your paired device settings. Try cycling through the light modes to ensure it's not accidentally turned off.

Connection issues with smartphone

Make sure Bluetooth is enabled on your smartphone. Close and reopen the Varia app. Try unpairing and re-pairing the Varia from your phone's Bluetooth settings and within the Varia app. Ensure your smartphone's operating system is up to date.

Brake light not functioning

Verify that the brake light feature is enabled in the Varia app or on your paired device. Ensure the device is securely mounted and oriented correctly. The brake light is triggered by significant deceleration, so very gradual slowing might not activate it.

Inconsistent alerts

Ensure the radar's field of view is not blocked by saddlebags, racks, or clothing. Update the firmware for both the Varia and your paired device. Test in different environmental conditions, as heavy rain or fog can sometimes affect radar performance.
