Rated 2 out of 5 by from Worked fine for one year This does what it says it does and I liked it until a few weeks ago when I was on a long bike tour and the top-right button started having problems. When I press that button to select a specific course or save a ride (or any other feature that uses this button) I get no action. If I keep trying it eventually works. Today was the worst because after my ride I pushed the button and it took at least 20 tries over the next several minuites for it to finally acknowledge. Something like that that gets pushed a lot (by Garmin's own design) should last longer than a year. Previously I had the Edge 500 and never had button problems with that one.

Rated 5 out of 5 by from Better than expected I've used the Garmin 510 since the day it came out. I enjoyed the 510, but the bluetooth uploads (or the lack thereof) and authorizations to connect to the phone finally drove me mad. I've used the 520 now on about a half dozen rides and conclude that it simply works. The screen and form factor are perfect. I'm thankful Garmin moved away from the touch screen; the buttons are so much more reliable and you don't get ghost screen switches when something brushes up on the gps. The strava integration never really worked on the 510. It performs better than expected on the 520. I'm going to look into turn it off at times (perhaps with a separate profile?) so that I can just enjoy a ride from time to time.

Rated 4 out of 5 by from A great little cycling computer I had looked around for quite awhile for a new cycling computer. I had a really old Bontrager but it had no GPS and basically measured speed and cadence and there were wires wrapped all around the bike. I settled on the Garmin because I use a Forerunner for running and I really like the Garmin Connect interface and the fact that it will also sync with Strava. I was initially drawn to the Garmin 820 with the touch screen primarily because I liked the mapping functionality but I chose the 520 because it was not a touch screen. I commute year round and I wanted a device that I could interact with while wearing gloves and regardless of the touch screen, they never work well with gloves in my experience. I am very pleased so far and would highly recommend this cycling computer to anyone looking. It would have received 5-stars if it included the same mapping feature as is found on the 820.

Rated 4 out of 5 by from Easy to use Bike computer I upgraded my dying bike computer to the Garmin Edge 520. Though pricey, it has been well worth it. the set up was very easy, It paired quickly with my Tickr heart rate strap and worked flawlessly in my first ride. Lots of climbing and all the info was great. It synched with Strava seamlessly. I have not used the bluetooth wireless. The small rubber cover for the USB port is easily torn. Mine broke off when I plugged in the cable to charge it. This would be my only reason for only 4 stars.

Rated 4 out of 5 by from Nice small size with a lot of functions Have had for a week. Still trying to get the navigation to alert when a turn is appoaching. Wish there was a way to import routes without having to drag and drop files into the Newfiles drive. Have to search online to get the instructions as there is no printed operations manual. Surprised how lose the mount is seems too easy but does stay in place. Was surprised that the Strava Live Segments requires Premium membership. But Garmin segments are free but I wanted to use Strava.

Rated 4 out of 5 by from Evolutionary, Not Revolutionary I upgraded from an Edge 500 and this is clearly better. Set up and transfer of my profile was a bit of bother but nothing too painful. Battery life is good considering how you link your entire life to it.

Does the Garmin require the purchase of sensors or are they included ? 

Asked by: CyclingPrincess
This unit is not packaged with any sensors but REI stocks the 520 Bundle that does include the sensors:

Items can be sourced from multiple countries and the country of origin can change. Because of this, we are only able to state the Edge 520 is imported.

I have a older Garmin speed/cadence sensor and the older Garmin heart rate monitor (GSC-10, and I'm not sure the heart rate monitor model but its 3ish years old, both use ANT+). Will this device work with the older speed/cadence sensor models? Thanks!

Asked by: jmonk
This bike computer is only compatible with the following speed and cadence sensors from Garmin. This computer is not compatible with the GSC-10 model. The 010-10997-00 and 010-10997-07 heart rate monitors from Garmin are both compatible with this computer.

I have the Wahoo heart monitor and cadence sensor. Wondering if they are compatible with the Garmin? Also would like to add a speed sensor (on the back wheel for winter training). Garmin or Wahoo?

Asked by: blgtbirdman
If your Wahoo heart rate monitor and cadence sensor are ANT+ compatible, they will work with this bike computer. For training indoors the Garmin Speed Sensor is a great choice.

I'd like to use the 520 for backpacking trial navigation, in addition to it's primary use as a cycling computer.  Can I load trail maps, mark waypoints, and use other basic GPS functions?  

Asked by: Mark
This unit is best used on a bike as the beta and metrics are designed for cycling. This unit does not have any internal memory so it cannot store any mapping software. The antenna does not allow for optimal reception under tree cover and the battery is not built for extended periods on the trail.
