Overview
Garmin has posted Public Beta 31.20 - Pre Rollout for the Edge 540, Edge 840, and Edge 1040 cycling computers. Compared with the shorter 31.18 post, this release comes with a more concrete fix list and looks clearly focused on stability.
Instead of adding major new riding features, Garmin is cleaning up crash behavior, Connect IQ-related lag, and a handful of display problems in weather and elevation views.

Garmin Edge 540/840/1040 Beta 31.20 Changelog
Garmin lists the following fixes in version 31.20:
- Fixed a crash using RTS to edit data screens
- Fixed a crash on the course list
- Fixed step goal being changed unexpectedly
- Fixed Connect IQ data fields causing UI lag or freezing
- Fixed the options menu while the start/stop/pause overlay is present
- Fixed elevation profile manual scale adjustments
- Fixed dew point and UV-index values in the weather widget
This is a strong maintenance beta. Garmin is targeting issues that affect both the device's stability and the accuracy or readability of what riders see on screen.
Why Version 31.20 Is Important
It Fixes Real Ride-Flow Problems
Two of the listed items are direct crash fixes:
- data screen editing via RTS
- course list access
That means 31.20 is tackling failures in normal pre-ride and navigation workflows, not just background polish.
Connect IQ Users Should Care
Many advanced Edge users depend on Connect IQ data fields. Garmin specifically says 31.20 fixes CIQ fields that were causing UI lag or freezing. If that works as intended, the whole ride computer should feel more stable.
Smaller Display Fixes Still Matter
Version 31.20 also improves:
- elevation profile manual scaling
- weather widget dew point values
- weather widget UV-index values
- options menu behavior with the start/stop/pause overlay on screen
These are the kind of bugs that do not sound dramatic but still affect trust in the device during everyday use.
Previous Beta Context
Garmin also points back to earlier updates in this branch:
- 31.18 fixed a translation issue that inserted "Day" into date strings
- 31.15 added gear tracking improvements and fixed radar color mode behavior, false climb credit on flat roads, auto zoom while following a course, Strava widget freezing, ClimbPro display issues, shifter summary issues, course navigation crashes, and recent finds search crashes
So 31.20 continues the same pattern: steady tightening of stability and ride UI behavior.
How to Install Edge 31.20 Beta
Garmin says you must:
- Be enrolled in the Public Beta Program
- Have Wi-Fi added on the Edge device
- Open Main Menu > System > About > Check For Updates
After the download finishes, you may need to scroll and manually choose Software Update 31.20 to begin installation.
If your Edge shows "Collecting diagnostics...", Garmin asks beta users to go to:
- Menu > System > Diagnostics > Upload RAM Dump
Conclusion
Garmin Edge 540/840/1040 software version 31.20 Beta is a practical bug-fix release. It will be most relevant for riders who have seen crashes, Connect IQ slowdown, or inconsistent weather and elevation views on the current 31.xx branch.
For beta testers, this looks like a worthwhile update because it is focused on actual ride experience rather than minor invisible maintenance.
