Summary: Pros: very strong GPS. Gets reception where other devices (500, 800) fail. Hardware quality is solid, everything works nicely on the bike. Cons: Garmin Connect iOS app is a freaking joke. Why is a company like Garmin trying to corner their customers into using this non-functioning app is beyond me. I have updating firmwares regularly and ride uploads over BT have only worked ~25% of the time.
Summary: Mixed feelings on this guy. I also have the 500. Here goes: The 500 is way easier to read in any and all conditions. The 510 isn't awful but clearly inferior to the 500 in that regard. Aside from that though , the 510 is a better unit. Locks into satellites immediately whereas the 500 takes a bit of time. I do prefer the slightly larger screen size of the 510 so I can place more stats on each page. The Bluetooth however, really ticked me off.
OK, but not for me. Exchanged it for a Garmin 500.

Summary: I was upgrading from a Forerunner watch and was really excited about the 510. After two days, I ended up returning the 510 and getting a Garmin 500. I really wanted to like the 510, especially with the ability to upload via bluetooth which would have been very convenient. However, I couldn't get past the screen. With the backlight on (which is what you see in all the photos), it is very bright and easy to read.
Summary: It collects the data the data I want to keep from training rides. However, I fail to see improvement over edge 500. When I first bought it, navigation was not working due to lack of working firmware. Now, it's fixed I load the ride into 510 before leaving the house. Good: 1. Collects speed/hear rate/cadence data 2. Support navigation w/ tcx/gpx file format Bad: 1. A lot of firmware issues initially. Seems like garmin released a software w/out doing proper QA. 2.
Nice computer, but display is not as bright as I would like

Summary: Just a quick note. I bought this through my local bike dealer when I bought a new bike. I bought the Edge 510 bundle with the HR strap and out front mounting bracket. I am also using the Trek Duotrap speed and cadence sensor. Overall, it works quite well and screens can be customized to meet your preferences. Not sure how accurate the calorie count is as others have mentioned. Seems a little low compared to the Polar HR monitor I was using.
Summary: After switching from 500 to 510 (note that I said *switching*, not *upgrading*) and using the 510 for a couple of months I decided it was time to express how I feel about it in the hopes that maybe someone at Garmin is listening. And if it helps somebody make a decision, that's good too :) My reason for switching was pretty much forced. I really liked my 500, but I got to the point where I wanted GLONASS, too.
Summary: I have been using an Edge 305 for a few years. When the 510 came out, I decided I would spring for the upgrade. I've been using the Edge 510 now for several months and have explored most, if not all, of the featureset. There are some good things about this device, so let me start there. - The battery life is much better than my 305. The ~15 hours seems about right; I no longer have to worry that I'll run out of battery on a double century or hundred-mile mtb ride.
Summary: This Edge 510 does a good job at it's most basic function. It is more accurate and easier to use than a phone for tracking your rides. Uploading rides via Bluetooth is also quite convenient, though I find that sometimes, randomly, the device will stop uploading rides in the background until I open the Garmin Connect iPhone app again. (And the Bluetooth connection really should be used to display information on incoming calls, texts, and notifications.
