Edge 840 Solar GPS Bike Computer
Product Details
Web ID: 20055860Just learning
This was a gift and I am just getting started learning the features. So far it has been pretty easy to load a route and save the ride. I need to make the font a little larger or at least define the contrast better. Let me know if that is possible

Great tool to improve training and performance
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
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
*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
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
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.
