Garmin 820

[Tom Kunich]

The 820 and 830 appear to be the same unit probably with just a software upgrade. Is that correct or is there some sort of major change?

– Increased display size 13% from 2.3” to 2.6”
– Increased battery life from 15 to 20 hours, and to 48 hours in battery saver mode
– Significantly increased processor speed: Results in much faster route calculation (see videos)
– Added Garmin Heatmaps: This follows what Edge 1030 had, included in maps routing on unit
– Added ClimbPro: Automatically shows how much distance/elevation remains for each climb on route
– Added Mountain Bike Metrics: Shows Grit, Flow, and Jump details on both unit and Garmin Connect
– Added Trailforks maps to unit: Added global Trailforks data/maps to baked-in data on unit (no downloads required)
– Added ForkSight: Automatically shows mountain bike trail options when you pause at fork in trail
– Added Heat Acclimation: Will automatically take into account heat/humidity for performance/recovery metrics
– Added Altitude Acclimation: Will automatically take into account (high) elevation for performance/recovery metrics
– Added Training Plan API support: This includes a redesigned structured workout execution page
– Added Hydration/Nutrition Smart Alerts: When using a course/route, it’ll automatically figure out how much water/calories you should be taking
– Added Hydration/Nutrition Tracking: It allows you to record this data in ride summary screens and log it on Garmin Connect
– Added Edge Battery Pack Support: You can now attach the Garmin integrated battery pack to the Edge (you can still use generic USB power too)
– Added Bluetooth Smart sensor support: You can now pair Bluetooth Smart sensors like heart rate, power, and cadence
– Added Performance Power Curve: This shows you your mean maximal power over different durations/time frames (like many training sites)
– Added Bike Alarm Feature: Used for cafes/bathroom stops, emits loud alarm if bike is moved
– Added ‘Find my Edge’ feature: Automatically record exact GPS location on your phone if Edge is disconnected (in case unit pops off)
– Added Training Plan Weather/Gear Tips: Basically tells you to HTFU when it’s cold out
– Changed user interface bits: Tweaked user interface, which might take some people a few rides to get used to (or just myself)

It sounds like there were so many changes that is why there are so many 820's on the sale sites.

Incorrect the main hardware upgrade is much more powerful CPU, which is one
of the reasons for “sir my Garmin ate my homework” ie the unit would
essentially get overloaded and bug out.

I wonder if they have designed and built their own uProcessor despite the easy availability of the most powerful processors commercially.

Sony I believe in the 830/530 note these where the units to fight back
against Wahoo who introduced units that arguably worked a lot better.
