## Questions & Answers

**Q: I have a bag on the seat post. Can this be mounted on the seat itself with an adapter?**
A: According to Garmin instructions (available on their web site), the unit has to be in a vertical position (with the accuracy of several degrees. This is because it uses a fairly narrow (40 degrees) 24 GHz radar beam to detect cars. So, it would require a specially designed adapter. Garmin does not make such adapters for attaching radar to the seat because the radar emits 12 dBm (8 mW) of microwave radiation, and for health reasons it must be kept at least 5 cm from your body parts. If you attach it to your seat, you may subject sensitive parts of your body to microwave radiation with a dose higher than the dose which FCC considers safe.

**Q: Can this detect when another cyclist is about to overtake you, or can it only detect cars?**
A: Yes it can detect cyclists approaching from behind.  Sometimes confusing but it is very helpful as regards approaching cars.  It will even show graphically how many cars are approaching.  If in a paceline and someone pulls in behind you it will beep as if noting a car and then it will resolve itself pretty quickly.  It is a necessity and I don't ride without it now

**Q: Has anyone come up with a way to mount this to a bike rack? I have a Bonrager rack if that matters.**
A: I have a Bontrager rack and mounted the unit on a plastic tube that I then attached to the rack with zip ties. Unfortunately this out the unit too far away from the Garmin computer, so sometimes, when the battery was low it would stop working consistently.

**Q: Just got this device and mounted on back of seatpost. It does not look/feel secure at all with rubber bands easily slipping. Is this normal?**
A: I didn’t use the bands as I have a saddle bag in the way. There are more secure seat post mounts if you aren’t feeling the bands. I had to spend $45 on a 3D printed Garmin strap clip to attach it to my saddle bag, as Garmin doesn’t make one. C’mon Garmin. I also stuck a zip tie mount for a security cable just in case. More options than an answer good luck.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Works GREAT!
*by P***L on July 16, 2024*

After about 6 rides of more than 20+ miles each, I feel comfortable writing a review about the Garmin Varia RTL515. First, let me say that this Radar with Taillight works exactly as advertised and I can easily recommend it to any bike rider. That said, here are what I hope may be some helpful notes:- I use the radar with my iPhone 14 Pro and the associated Varia app- It took me less than 10 minutes to unpackage, mount, install the app and pair to my phone (note that for my rides my iPhone is attached to a mount on the handlebars)- Some have reported issues with the mounting hardware that comes with the device. I encountered no issues at all (installing or while riding)- Be sure to use the audible sounds and not just the visual (in other words, keep the volume on and up)- The radar detected approaching vehicles 100% of the time and about 85% sooner than my hearing did- I found the biggest benefit comes when I have to merge from the shoulder of the road out into traffic to make left hand turns or move out from a right only lane. As I have aged (now 65 years old) I don’t have the flexibility to turn around and look like I once had and this device helps in indicating if there is oncoming traffic and if there is, I can adjust my speed to slow down (or speed up) until it is clear. But make no mistake, DO NOT RELY SOLELY ON THE RADAR. Always use your eyes and ears!- I can say, from my limited experience, that the battery life seems solid and unless you’re doing 6+ hour rides (just my estimate), you will be fine and won’t run out of juice- Speaking of battery life, using the Varia app while using the Strava app to log my ride, I used up approximately 15% of my iPhone’s battery on a 2 hour rideMy only gripe is that there is no integration with my Apple Watch. It would be very beneficial to have haptic alerts. I did find a third party app that supposedly does this but have not purchased it ($5.99).This device may not be for everyone but if you are looking for some added, reliable safety when you ride, it is worth it and, in my opinion, at a reasonable price.

### ⭐⭐⭐⭐⭐ Will Not Ride Without It!
*by J***N on April 25, 2025*

This has quickly become the most important cycling accessories I own and will literally not road cycle without it. I have lights front and rear that I always ride with, but this little gadget gives me warnings and situational awareness especially when I'm on a steep descent. It integrated seamlessly with my Garmin head unit and lets me know how many cars are back and rate of closure speed. Charging it is really simple and it last for hours. Its very accurate and will discriminate multiple cars. It does pick up faster riders (which happens a lot to me!) and won't alarm in a pelaton. I like the small, no light version as it was easier to mount and I tend to keep my rear light higher up. If you ride a lot, just get it!

### ⭐⭐⭐⭐⭐ Does the job.
*by T***G on October 20, 2023*

I was hesitant to get this light/radar simply due to the price. I wish it was about half as much as it is. That being said, I got it on sale for 50% off so I’m very happy with my purchase now. This light is fantastic if you use a garmin bike computer. It syncs up in seconds and the battery lasts me quite awhile. I’ve taken it on 3 rides that were all over an hour without charging and it was still going. I typically charge after every other ride because I don’t want it to die while I’m out so I’m not sure how long it will really last, but it’s longer than I’ll ever need. The radar works fantastically, it catches cars and other cyclists and gives you an alarm warning, flashing red screen, and a readout of how close they are to you on your computer. It comes with mounting stuff that should fit most bikes, although my seatpost is a bit of an odd shape so I’m hoping to find something that’s a little more secure. There is zero risk of it falling off, but it does slide down on the post because the rubber pad is just a tad too small for my seatpost.
