GarminVaria RTL515 Radar With Tail Light(Return to Product Page)

I was unaware of the product until very recently. On group rides on narrow roads a rider in front of me would call "CAR BACK" without mirrors and without looking back. I thought he had super-human hearing, as I didn't hear the car until much later. He told me about the Varia. It has never had a false-negative (ie NOTdetecting an approaching car) It will show another bike rider if he/she is closing on you ( I think this is a feature!) If other riders behind are at about the same speed, it won't alert. The only false-positives for approaching cars have been when on a frontage road to a highway, when approaching cars on the highway appear to be coming up behind you. This is the FIRST cycling upgrade my wife insisted I buy, as it adds to safety. I'm 61, so neither my hearing nor my flexibility to look back are improving. THIS IS A MUST HAVE for anyone that rides on narrow roads. GET IT, you can't afford not to.

I read all the positive reviews saying this is a device you never thought you needed but can't ride without. It's true!! I upgraded to a Garmin Edge 1030 plus from an old Edge 800, and soon bought the Varia headlight and then the Varia VTL515 tailight. The Edge integration is great, the light if very bright, and the radar feature is truly something that provides some comfort in tricky intersections and small shoulder roads. I also like having it on gravel and backcountry fire roads because I can take my favored line without worrying about looking back on sketchy surfaces for an a ATV, dirt bike or 4WD vehicle coming. It won't prevent you from getting hit, but does let you know how much shoulder you can occupy safely as whether it's clear to make a left turn from the right shoulder. It's by far one of the best cycling devices I've bought (love my Edge 1030 as well as my headlight mount under the Edge). If you are on the fence, I recommend you go for it.

I've used the 515 for a couple months and I think this is a nearly essential piece of safety equipment. Connection to my Edge 830 is seamless and the the amount of information regarding the number of cars, distance, speed, etc is extremely helpful. I haven't attempted to calibrate the detection distance, but the unit alerts me to vehicles long before I usually hear them. I've had a few false positives, but almost no false negatives, which is key. My only complaint is that I rarely get more than 7-8 hours of use before it needs to be recharged and there doesn't appear to be a way to get a quantitative measure of remaining battery life.

I have had both the radar only and the radar plus light. The 515 turns my light and radar on which allows me to skip two activations in the back. A small plus. What makes it more convenient than the 315 is the 515 battery life is significantly longer. Less removals for charging. I know, I'm lazy. Other than that, they are both fine and I use now use the 515 all the time.

A lot pricier than your average tail light...but then again, your average tail light doesn't sync up to your Garmin head unit to alert you when cars are coming. I really like how it displays the cars as dots on the screen, and then goes green / clear after they pass.

Also picks up cyclists too, which can be a tad confusing at times. But overall, glad I made the investment in extra safety on the road.

The Varia radar is seriously awesome. My buddy had one and was able to call out whenever a car was coming up behind us on a ride. I quickly bought one shortly thereafter and it is a necessary item whenever I'm out on the road. The peace of mind that it gives while descending at speed and having a warning when a car comes up behind me is worth the price alone. I pair it with my Garmin Fenix watch and it gives me an alert, love it.

A must have. The updates 515 has Bluetooth so you can connect to a phone app that gives super loud alerts. Battery life is better too. It has never been wrong and will ALWAYS let you know that a car is there. You occasionally get false positives but that is okay. Just makes you more careful.

Great little device for warning you about approaching traffic from behind. I have mine paired to my 520 Plus computer up front but I cannot hear the beeps due to high frequency hearing loss. I also have it paired to my iPhone and connected to the Varia app. This allows me to start up the app, run the phone volume all the way up and then put my phone in one of my rear jersey pockets - now I have enough volume to hear the audible tones and be alert to approaching traffic. The ability to connect it to multiple Bluetooth devices is a great feature. I love it!

The RTL515 works great and connects easily to my Garmin 520 Plus. I like that when the battery is low a message appears on the computer. To get the most out of the battery I always use the flashing mode. Regardless of the mode the light is plenty bright. You can use this with the phone app, but it is sometimes flaky, but I think it is the app. Sometimes the pairing drops for no apparent reason, but generally reconnects. Never a connection issue with the computer, however. I found connecting works best when you first turn on the unit. After it pairs, then change to a different mode. If you use any other Bluetooth/Ant+ devices, turn on after the Varia is all set. I use earbuds as the warning sound from the app is much louder than coming off the computer without them, but it still is sufficient. I've never had a false negative meaning it not picking up a vehicle when it was actually there. Occasionally, there will be a false positive, i.e. other riders if farther back in a group. Up & down hills it will lose a vehicle if detected at one time, but will pick it up again when the road flattens. It would be nice if Garmin would tweak the unit for more vertical detection for consistency.

Since I use a mirror, I wasn't sure this would add a lot of safety to my riding, however, I've been pleasantly surprised that I'm often alerted to the presence of an approaching car well before I notice it in my mirror. I don't use the function that allows you to watch an approaching vehicle on your smartphone. This seemed like more of a distraction than a benefit, so I never entertained using it. I do ride on backroads where cars can appear from a driveway or crossroad with little warning, so I have been very pleased with the Varia keeping me aware of vehicles. The audible tone is transmitted (Bluetooth) to my hearing aids without bothering nearby riders. Besides, several of them have their own Varia, which I hadn't noticed until I got mine. By the way, I think it picks up vehicles at a greater distance than 140 meters, but I haven't actually measured it. This does everything as advertised, which is kind of a new experience!

It was on sale. I thought it was a gimmick. I gave it a try. Changed my awareness on the bike. Added safety. Like many other reviews here, I didn't think this idea had much merit before using it. But, it gives me a 360 degree sense while on the bike that I never had before. It sees anything that is approaching from behind -- cars, trucks, other bicycles -- as long as their speed exceeds my own. Fabulous. I am really glad I got this device and would recommend it highly. Integrates perfectly with my 530. Like all Garmin stuff it's just a bit too expensive, but works as advertised.

Truly amazing technology when package with Garmin's computer's. How do you place a value on safety. This truly adds to overall cycling safety and awareness of your surroundings. Sync's easily and great battery life. Whether you ride on roads, trails or other...the sensitivity is impressive. The only potential negative for road riders in significant traffic, I suspect you'll grow weary of the constant signals. However for infrequent traffic, country roads or simply worrying about the occasional rider coming-up behind you, truly impressive safety tool! Will never ride without it...

I never expected the multiple cars to be shown so accurately. I have it paired with EDGE 1000. The Coloring Alert displays well no matter what the underlying screen is, even the temporary direction guidance or lap notifications. Always pairs automatically !! The ONLY Draw back is the rubber band mounts, I did buy the permanent screw on mount. I have also paired it with my VioActive 3 [non-music] I do not find that to be helpful, on the screen on the handlebars is where this device shines. I commute regularly so am often in low light conditions that cars should have lights on but don't. This supplemented with a good mirror to verify cars are moving over is the way to go. BTW I love the EVT Safe Zone Mirror Large surface and out from eyeball can see quite a bit.

At first I thought this was a gimmick and didn't need it, but after using it now after 5 rides this is one of the best upgrades to you cycling safety. It just works in telling you cars are approaching, great for making left turns across traffic, could never look that far around. You must watch when going over hills the cars are hidden until you are in line of site. works the best out in the country. I even got my wife one because at events she bikes solo!

I have bee using a Garmin 510 for at least six years. After a recent software update I noticed this radar unit listed in the menu. Upon a little research I found that with the update this unit was compatible with older Garmin units. I purchased this rear light/ radar unit and have been using it for the past month. I've been impressed with its performance and ease of use. I ride mostly on paved county/ farm type roads and average about 700 miles month. The unit warns me when traffic appears about 400 ft behind and graphically shows the progression toward me. I have found it very helpful when I have to merge into a traffic lane. I always look before moving but this shows the gaps in traffic and lets me know when to look back. Good product

This product has made my rides a lot less stressful. I love getting a warning that a car is approaching before I can hear it. When I'm flying down a hill it's comforting to glance down at my Wahoo Element Roam, and see a nice green line, letting me know that the road is all mine. I would have bought one sooner had I soon it was compatible with my Wahoo device. I was proud to say goodbye to the little mirror on my sunglasses. This is much better, and I like a little cooler!!

I use this with my new Garmin 1030 Plus. I feel much better now when turning left. Even with a mirror, I like the radar for giving me the added security!

Wish I bought one sooner, as it's a brilliant product. Picks up vehicles way sooner than my mirror or my ears, and graphically shows how many vehicles, and closing speed. And it paired instantly with my Garmin computer. A huge advancement in safety, and other than being a little heavy it's a must-have for any road biker or commuter.

Be seen day or night and be aware of anything approaching from behind. I never ride without it. A must for every cyclists.

Wish I had bought this sooner than I did! Held off for years using helmet mounted mirror! That was dumb! This is so much safer...works perfectly with my Edge 830! Only challenge I had was where to mount it as am also using a camera on seat post. Saw where some folks had mounted to seat bag using a home-made bracket! I did this and it works well - movement of the bag does not seem to bother it! Got caught in rain storm which didn't stop it from working but killed the camera! Only suggestion to Garmin is to add provsion for a safety cord as they have on the Edge units!
