Ik heb hem nu 1 jaar maar meerdere malen reset en terug nr fabr instellingen. Gps faillure, Temp die niet klopt. Navigatie traag en accu snel leeg. Maw niet kopen. Volgend jaar een bolt of iets dergelijks. Geen Garmin meer. Nu op vakantie weer dat t stijgingspercentage en Temp het weer niet doet. Wordt er gek van. Gps mogelijkheden werken ook niet zoals t hoort. Garmin geen gehoor behalve reset.

Top apparaat !

Navigeerd super, koppelt goed met telefoon etc. En zodra ik thuiskom synchroniseert mijn rit gelijk met Garmin connect en Strava (via Wifi). Accu loopt wel wat sneller leeg t.o.v. Polar v650. Zeer tevreden met deze aankoop.

goede GPS

Werkt prima. Moet navigatie nog uitproberen. Wel viel het me op dat zeker onder bomen de aangegeven snelheid nogal wisselt. Een verschil van enkele kilometers per uur.

Veelzijdig apparaat, trage navigatie

Nu ruim 1 jaar in gebruik. Bediening is even wennen, tijdens het fietsen reageert het touch screen wat traag evenals de navigatie. Regelmatig mis ik op de racefiets een afslag doordat de 820 te traag meebeweegt. Verder veel info, schermen naar wens in te vullen. Accu is na ca 12 uur wel leeg, voor mij geen bezwaar.

Detailed product description

GroupTrack will find your friends again

You don't have to feel alone if you ride faster or slower than your friends. With the new GroupTrack feature, you can pair it with Garmin Connect™ so you always know where your cycling friends are and they can see where you are.

The ultimate touchscreen

The Edge 820 is equipped with many powerful features, but especially the high-resolution touchscreen will appeal to you. An ambient light sensor automatically adjusts the brightness of the screen so that you can see everything at a glance crystal clear. The capacitive touchscreen is easy to operate even when it's wet or when you wear gloves.

Advanced performance measurement

The Garmin Edge 820 bike computer is compatible with ANT+ sensors. You can connect the 820 to speed sensors, cadence sensors and heart rate monitors, and for even more performance data, the Edge 820 is also compatible with ANT+ power meters. The unit can also be integrated into ANT+ electronic switching systems, such as Shimano DI2 and ANT+ compatible bicycle trainers from Tacx, for example. By using a heart rate band, you can also have access to all kinds of physiological data. While cycling, you can keep an eye on the VO2 max value, and after cycling, you can use the function Recovery advice to analyse your data. With this tool, you can see how long you need to recover before you venture back to the next intensive bike training. This system of paired sensors, accessories, bike computer and back-to-back analysis via Garmin Connect keeps you up to date with your physical condition every time you ride.

Garmin Edge 820 performance features

VO2 max, recovery time, Strava Live Segments, Performance Condition, Stress Score, Extended Cycling Dynamics, FTP and Watt/kg tracking. All means to improve your form.

Turn-by-turn Navigation with preloaded Garmin bike map

Use GPS turn-by-turn navigation to find your way, both on ground roads and untraveled paths. The Garmin Bicycle Map provides navigable roads and cycle lanes, elevation data, points of interest, and the ability to find addresses. When you use the tour function, the Edge 820 selects a bike-friendly route, from start to finish, based on the distance you want to travel.

Compatible with the Garmin Varia products

The Edge 820 is equipped with accident detection through an integrated accelerometer. If you get into trouble, the map location will be passed to a contact to warn you in case of an emergency. To help prevent accidents, the Edge 130 is also compatible with our extensive range of Garmin Varia™ products for safer biking, including rearview radar and smart bike lighting, so you can keep a good view of the surroundings while you're riding. When the Edge 130 is coupled with this bike lights or the radar that detects oncoming traffic, you do not only have good visibility, but you also remain visible to other road users.

Adapt to your wishes and pair it with your phone

It is your device, so you can personalise it as you like with the customisable data fields and free apps that you can download. Check out the offers in the Connect IQ store and choose to customise your Garmin Edge 820. Remember that as you ride your bike, the Garmin Edge 820 GPS cycling Computer also keeps you connected to the rest of the world through smart notifications, live tracking, social media sharing and automatic upload to Garmin Connect, Garmin's free online fitness community.

LiveTrack is easier now

LiveTrack, and GroupTrack allow your family, friends and co-drivers to determine your location in real time while you're riding, and the features are even easier to use now. Enabling autostart allows you to pay more attention to the ride and less to the technology. Both LiveTrack and GroupTrack can automatically detect when you start cycling, eliminating the need to pick up your phone. Auto start is also available for the new Strava Beacon, allowing Strava Premium subscribers to use the same great feature. So that while you're cycling, you know that the people at home and the other cyclists know better than ever where you are.

Wherever you go with the Garmin Edge 820

Whenever you ride in remote forests with thick foliage or along tall buildings in the city, thanks to the high-quality GPS and GLONASS chip, the Edge 820 can determine your position quickly and accurately, anywhere in the world.

What is the battery life of the Garmin Edge 820?

New extended battery life for longer rides. Up to 15 hours in GPS training mode, and 50% more in the new battery saving mode.
