Great tool to improve training and performance
on April 6, 2025
Posted by: Sammmy
Compatible with all you bike sensors and gadgets, great tool to maximize, track and improve your rides. Touch screen is a great advantage to toggle between screens during rides. Recommended

Decent bike computer but screen too dim
on April 6, 2025
Posted by: OVP_Biker
Overall this is a good device with lots of features, but the screen is very dim and difficult to read in either the dark or direct sunlight. The solar charging doesn’t offer much benefit either and the battery drains pretty fast.

I’m keeping it, almost perfect
on April 1, 2025

*photo is of the the larger 1040 (or whatever #it is garmin, it was unnecessary for me and i prefer the 840).
Plan ahead for time to sit down with necessary charging, WiFi, and account login information to setup the device.
Once setup - it’s awesome. It lasted 6 days (lots of desert sun exposure) on the solar charging, had at least 6-10 different routes loaded, sharing information/updates/notifications, checking the screens/switching between screens for various metrics during long bike rides…idk how much more I could have been using unnecessary screen time with it, but it never died (#teamamerica).
Also it does passively charge in the sun when it’s not in use!
I’m keeping mine.
Even though I wish it had more options/range for articulating how it sits on my drop bars. It’s not enough to negate the other advantages of it.

As a replacement for my old 540...

It's probably a no-brainer as to why this was a HUGE improvement! Everything works great, and the additional data has been very useful!

Poor readability
on March 7, 2025
Posted by: JimLSeattle
Too much white space, poor font makes for inefficient use of screen space. I find this to be much less readable than my Wahoo Roam 2. I've tried optimizing the screen content but can't fit as much useful data on the screen and still have it in a readable format. It's also missing nice touches like coloring gradient, etc.

Cannot connect to Garmin Connect
on February 25, 2025
Posted by: PamInAustin
I bought this several months ago and cannot get Garmin Connect to recognize my device. I have tried everything…deleting and reinstalling Garmin Connect, installing it on a different computer, buying a different cable. Nothing works.

Buggy and unreliable but great when it works.
on February 11, 2025
Posted by: SalemCDB
I have had the 840 Solar for about a year now. I feel like I need it for navigating long rides and it is very good to have when it works, but it goes dark, freezes or simply fails to track distance, HR, speed or the other metrics too often to be used as a training tool. Amateurs may find the 840 worth it overall, but serious riders, club riders and fitness enthusiasts need to consider more professional options.

Returned and exchanged for the Edge 1050
on January 26, 2025

Display is difficult to read in the sun. To fix that you have to adjust the backlight settings, which completely chewed through my battery in a 5 hr ride. Also, the Garmin was in the sun during the ride but did not gain any charge.
