Forewarned on every ride: The Varia™ Rearview Radar RVR 315 from Garmin The Vaira™ 315 Radar makes you more clever and attentive on the road. The device is attached to the seat post and provides visual and audible alarms to warn of vehicles approaching you from behind at a distance of up to 140 metres. Connect your Varia to the Garmin Varia App to keep track of your surrounding area. You will be connected with coloured Notices on the display of your compatible device to warn of approaching vehicles. If you don't have your phone with you, you'll be alerted to approaching cars by sounds and vibrations for added safety. And this from a distance of up to 140 metres.
