The SmartSense Radar broadcasts ANT+ and can be paired directly with many popular cycling head units and watches (Garmin, Wahoo, Hammerhead, etc.) to show radar alerts. This means you have up to three options for how to see and hear Radar alerts:
- Cannondale App
- SmartSense Radar Display Unit
- 3rd party head unit or watch
Connecting Radar to your head unit or watch
Refer to your device manufacturer's information for whether it is compatible with Garmin Varia Radar and follow their instructions for how to pair the Radar.
- Power SmartSense ON so the Radar receives power
- On your device, pair the Radar
- If you have SmartSense Gen 2 (2025+) you may need to put the device into pairing mode. Turn it off by holding the power button on the side of the radar for 3 seconds. Then hold the power button for 7 seconds until the LED flashes purple.

Configuring Radar settings on your head unit
When using Radar with a head unit or watch, customization of settings will vary and depend on the device. Refer to your device manufacturer's information.
The Radar settings options within the Cannondale App only control the behavior in the app and with a connected Radar Display Unit.
Troubleshooting
If the Radar does not appear in your device's list of available sensors to pair or does not connect, check that the Radar is getting power from the SmartSense battery. See: SmartSense Radar does not work
