Nice find sounds like some fun features in the new versions. 510 looks sleek.

These 510 and 810 do not seem to provide any substantial improvements over the old models. But Garmin dominates the market anyway so I guess they don't have to.

This Is Your Edge

The touchscreen Edge 810 is designed for the cyclist who wants it all — navigation and advanced training capabilities in 1 device. It offers connected features¹ through your smartphone, including live tracking, social media sharing and weather. The 810 is compatible with optional detailed street or TOPO maps, so it can guide your ride for touring, commuting or extended activities where you might need onboard maps and navigation. Because it’s GPS-enabled, Edge 810 provides accurate data and navigation capabilities, anywhere in the world.

Track Every Detail

In addition to the mapping capabilities, Edge 810 records your distance, speed metrics, ascent/descent, grade and more. It’s also compatible with ANT+™ sensors that measure your heart rate², speed/cadence² and power³. The activity profiles feature allows you to customize data fields and device settings based on cycling activity, such as road, mountain or touring. Switch profiles with a simple swipe of the touchscreen and your device will be set up to show the data you need for that ride.

Get Connected

Edge 810 offers a suite of connected features when paired with your smartphone (Apple® or Android™) and the Garmin Connect™ Mobile app. This allows you to gain comprehensive, accurate ride data from a dedicated device, while saving your phone battery. Edge tracks the data and sends it to your phone using a Bluetooth® connection. Stay connected and share all the details of your ride with friends, family and your social media contacts. You can post an update immediately after your ride or race with details from your completed activity. You’ll create your posts via your smartphone, and the ride data’s already there, thanks to the interface with Garmin Connect Mobile.

Live Tracking

The live tracking feature allows your friends and family to follow your races and training activities in real time. Invite followers using email or social media, so they can view your live data on a Garmin Connect tracking page. Once they get your email invite, they can click to follow and see your stats and location on the map.

Weather

Get real-time weather conditions, forecasts and alerts (in areas with coverage) directly on the Edge 810 when it’s paired with your smartphone and the Garmin Connect Mobile app. This feature is useful for extended rides, and it lets you keep your smartphone safe and dry, while the weather data you need is at your fingertips.
Wireless Data Transfers

Now you can instantly store, share and analyze every detail of your ride. The Garmin Connect Mobile app allows for wireless uploads of completed activities from your device as soon as you finish recording an activity. You choose whether activities are automatically or manually uploaded. Once your ride has posted to Garmin Connect, your own “connections” can view them. You can also search your courses and workouts4 stored at Garmin Connect, download to your smartphone, then send directly to your Edge 810 — wirelessly. You can then navigate to the start of the course and use the Virtual Partner® feature on your Edge to race your previous activities in real time.

Purpose-Built Bike Computer

There’s no better bike computer to guide your ride. Edge 810 is rugged, waterproof and has up to a 17 hour battery life. The touchscreen is easy to operate, even with a gloved finger and when wet. Mounting options include a new out-front mount² for heads-up positioning and a standard quarter-turn mount.

¹When paired with your compatible Android or Apple device.

²Included with some models, sold separately on others.

³When paired with ANT+ power meter.

4Future release of Garmin Connect Mobile will allow you to explore and download courses and workouts from other Garmin Connect users.

Sounds good, but .... I would like to be able to post ride data to Strava... Or, even better, if the Starva app can be updated to talk directly to the 810.
