The Garmin Varia RCT715 combines a rearview radar, a 1080p camera and a bright tail light in one seatpost-mounted unit. The radar tracks vehicles approaching from behind up to 153 yards and alerts a paired Garmin Edge computer, select wearables or the Varia app. The camera records continuously and saves footage before, during and after a detected incident, so you have evidence if something goes wrong. It suits road and commuter riders who want awareness of traffic behind them and a record of their rides; the trade-off against the radar-only Varia RTL515 is a larger body, shorter battery life and a higher outlay.

Riders rate it highly, praising the combination of radar warnings and incident footage. The main complaints are battery life and the app-based workflow for video.
The Garmin Varia RCT715 combines a rearview radar, a camera and a tail light in one unit. The camera records your ride continuously. If it detects an incident, it automatically saves footage from before, during and after the event. The tail light makes you more visible to motorists.
The radar detects vehicles approaching from behind up to 153 yards (140 meters) away. It sends alerts to a compatible Garmin Edge bike computer, select Garmin wearables, or the Varia app on a paired compatible smartphone. The app also lets you view footage, transfer videos and change camera settings such as data overlays.
Video records at 1080p and 30 fps, or at 720p to extend battery life. Three modes help you manage battery life: always-on, lights and radar only, or radar-activated, which turns the camera on when an approaching car is detected. A 16GB SD card is included.
