GarminVaria RVR315 Rearview Radar(Return to Product Page)

More a 3.5 star I�d say. Works well with my Wahoo, and I appreciate that the screen will show multiple cars and change from yellow to red when cars are approaching at high speeds. I�ve ridden with the Varia for about a month now, and I�ve only had two cars pass me that weren�t detected and didn�t show up. That said, often times other riders show up as cars, so this thing isn�t flawless and there is no way that I was able to research to adjust sensitivity. That said, I�d rather false alerts than missing a car completely. Do not rely on this thing to be 100% accurate and use it more as an added alert system to help be your eyes behind you, and it should do you well. It�s not a replacement for alertness and common sense.

Now, Garmin, let�s talk about the post mount on this thing, or more accurately the �security� rubber O ring and recesses on the unit. That is a garbage solution. I�ve seen friends units fall off multiple times from road chatter. For the cost, the lack of security on the fit is inexcusable. I�ve taped over mine to ensure it won�t fall off, and would strongly suggest others do the same. Otherwise, it�s a handy piece of kit.

My first ride with this radar detector and it was extremely useful. It easily mounted to my 2013 speed concept seat post and it easily connected to my Edge 520 bike computer. Out of the few dozen cars that passed me from behind, it warned me about every car. For the Edge 520, when there is a new car approaching, there is a short beep and the outer edges of the screen turns Red. Once the car has passed, the screen goes back to normal. If there are several cars in a row, there's only the 1 beep but the outer edge of the screen remains red until all cars have cleared. I was surprised at how handy this radar is and felt safer with it. I no longer need to constantly turn my head back to check for cars and can concentrate on the road ahead.

I like the alerts of cars behind me provided on my 520 Edge and even more on the Garmin app on my phone which I have mounted on in front of me on a quad lock. Sometimes get false readings when riding in a group. This should not replace a rear view mirror, but works great in conjunction with it.

THE REAERVIEW RADAR IS A BLESSING FROM SMART FOLKS. SAFETY IS ALL IMPORTANT & THIS BIT OF TECHNOLOGY GIVES CONFIDENCE ESPECIALLY WHEN TIRED THAT YOU CAN KEEP UP WITH VEHICLES APPROACHING FROM BEHIND. SAFETY IS ENHANCED FOR SURE.

I ride on the streets with very little traffic but the cars still exceed the speed limit, this warns me when they are approaching , allows me to enjoy the ride and not worry about cars getting to me before I hear them

Works great, with quiet vehicles I get an earlier warning than my ears can give me.

This is amazingly useful, it is so handy to know what is behind you and how fast it is approaching. One of the best bike accessory I've ever purchased.

100% reliable radar lets you know what's coming up behind you. Can't imagine riding without it now

I have now ridden 3000 miles in 2021. I always have the Garmin radar on. Has been accurate with vehicles 100% of

the time. Highly recommended.
