I ride about 150 miles per week. The Garmin has become a very useful tool. Haven't used the mapping capability yet but I like the unit. Does take some time to figure out if you're a newbie to Garmin. Plenty of YouTube videos for assistance though. Like the fact that the unit shows multiple items at once. No playing with buttons to scroll through information while you're riding.
replacing my old 510 which I lost, set up was great, took a little getting used to using the buttons instead of the screen. all was good for 2 months, then started getting crazy reading on temps, cal and elevation, would have 0 climb at end of ride. contacted Garmin, who said it was a bad barometer. since it was less than 6 months old, a new one is on the way. so that's cool...love the features of seeing who is calling or texting, lots of info screens you can set up...if the next one will only last, its a great computer...
I bought because I needed something I could transfer between bikes easily and so needed GPS. To be honest I have done very little to take advantage of much beyond the basics. I haven't even changed the preferences on the screen of what I see when riding. I wish it was easier to hit a button to switch the data saving for which bike I use, but to be honest, I don't care enough to take the time to go into my data to do it manually.
As an avid road cyclist, I purchased the 520 having used a Garmin 500 for three years. I was ready for the smartphone connectivity as it was always inconvenient to have to wait to download the 500 by data cable to a computer. The 520 lives up to it billing with all the features I was seeking . The Live Segment feature is awesome. The feedback from the unit give me exactly what information i was needing to train properly. All I can say is great unit!
The 520 is admittedly compact and lightweight but its interface is unintuitive and opaque. Quite obviously, the Garmin programmers never worked at Apple, for every function however rudimentary requires annoying scrutiny and multiple button pushes. Also, having large hands like Bart Simpson certainly doesn't help!
Replaces my 510 that started giving funky altitude readings. Seems more reliable than my 510, and I don't miss the touchscreen (which seemed like a bad idea for sweaty cyclist fingers anyway). Navigating functions in the 520 does not seem as intuitive as the 510 and boo for the loss of a programmable odometer, especially for multiple bikes. Four stars for that loss of functionality, otherwise 4.5 to 5.
This is a great product, as expected. It pairs nicely with the Garmin Vector 3, Garmin Varia Radar, and my iPhone.
The only complain is that they launched a newer version (520 Plus).
With products like this, the only limitation will be your budget.
ive tried the wahoo element bolt and still prefer harmons to other GPS units. The 520 is perfect sized and isnt an ipad at the front of your bike. 520 also got rid of the 510 stupid touch screen ! 520 is a great unit and it hasnt slipped a beat for me!
I use it on all rides, auto-sync with Strava, syncs with HR monitor and power meter. Pairs with phone and shows when someone is calling or when a text is received (assuming you have service and aren't lost somewhere in the mountains..). Only complaint there is that when a text comes in it covers the screen (activity fields) and doesn't go away until you manually dismiss it by clicking a button. Yeah, picky, but I wished the text message would just dismiss after 10 seconds.
A handful of features I still don't use (and probably will never use).
Battery time is fine, nothing to worry about there. Size is perfect, out-front mount puts it in the perfect position. Buttons can be a little tricky to find/press when you're wearing full-finger gloves. But if you're riding with full-finger gloves then you have other problems to worry about.
The virtual partner thingy works, but takes a little to figure out at first. It's cool though to create courses from your own PR to race against.
Happens rarely, but I've had it completely die on me mid-ride when battery level is fine. Luckily it keeps a record of the ride, and after restarting the unit I can pick up where I left off. My brother (also 520) had the same experience once so I know it's not just my machine.
4 stars only because it's great, but not perfect.
This is the third Garmin I have owned since 2007. Each new Edge has been a significant improvement over the previous one. The Edge 520 is no exception. It is significantly better than my Edge 500 in almost every way. The GPS locks in very quickly, the display is much larger, and the setup options are extensive. I also love the Bluetooth integration with my phone. This is a great bike computer.
Having said that, there are a few things I would change if I could. The display is large and can be configured in a seemingly infinite number of ways. While it is much larger and the numbers are bolder, without the backlight on, it can seem fairly dim when the light is at low angles. Better contrast control on the display would be nice. On the other hand, turning on the backlight pretty much takes care of the issue and doesn't seem to be a huge drain on the battery. The default maps are quite coarse, but downloading Open Street Maps (OSM) for my area took care of that. I was surprised at how little memory the device has - 105 MB. And no expansion slots for microSD, so only a limited number of OSM maps can be put on the device at one time. There are a few other nits I could pick, but overall this is a very nice bike computer and I would highly recommend the Edge 520 to any rider.
I purchased the Edge 520 as an upgrade to my Edge 500. I like that it syncs with my iphone Bluetooth.
I also like that it can alert me to phone calls and text messages. I also find it easier to sync my heart monitor and speedcadence sensors between my two bicycles. At the end of the day the Edge 520 will upload to Garmin Connect, Strava and Ride with GPS.
Great product. The 520 provides way more information than I will ever require - but I bought it anyway. The customizable screens help to sort out what you want and need. Accuracy appears very good, as with most other Garmin products I have owned. Works good on the indoor trainer too, if you get the speed and cadence sensors.
I love all the information that the Garmin 520 provides and how easy it is to set-up the screen just the way you want it. I do mostly Time Trials and I used to use a Joule GPS and the Garmin screen is much easier to see especially when your sweating so much in your aero helmet .
