[Firmware ChangeLog]: What's New in 31.22 Beta | Edge MTB

Overview

Garmin has started the 50% rollout of Public Beta 31.22 for the Edge MTB. This release shares the same changelog as the other Edge cycling computers on the 31.xx branch, with three fixes covering shifter controls, map display, and ClimbPro data.

For a mountain-bike-focused device, these fixes are relevant. Trail riders often use electronic shifting with multiple button configurations, rely on map data fields during navigation, and use ClimbPro to pace climbs on technical terrain.

Garmin Edge MTB Beta 31.22 Changelog

According to Garmin's official announcement, version 31.22 includes three fixes:

Fixed shifter button actions for configurations with more than 4 available buttons
Fixed map data field locked to track up orientation
Fixed ClimbPro remaining climb distance on the edit page

Why 31.22 Matters on Edge MTB

Shifter reliability matters on technical trails

Mountain biking often involves frequent gear changes across varied terrain. If shifter button actions were not registering correctly for configurations with more than four buttons, riders could lose gear control at critical moments on climbs or technical sections.

This fix ensures the Edge MTB handles the full range of electronic shifting inputs, which is important for trail riders who have customized their shift setup or use remote buttons.

Map orientation should follow your riding context

The map data field was locked to track up orientation. On mountain bike trails, riders sometimes prefer north up for orientation on unfamiliar trail networks, while track up works better for following a specific route. A data field that ignores that preference reduces navigation flexibility.

This fix makes the map data field behave consistently with the rider's chosen orientation setting.

ClimbPro is essential for trail climbing

ClimbPro is one of the most useful features on the Edge MTB for pacing long or steep trail climbs. If the remaining climb distance was incorrect on the edit page, riders could not trust the feature for planning their effort.

On mountain bike routes where climbs are often steep and punchy, accurate remaining distance data helps riders decide when to push and when to hold back.

Previous 31.xx Branch Context

Garmin also repeats earlier changes from the branch:

31.21 fixed Daily Suggested Workouts showing on the main menu when toggled off and corrected Stamina Distance/Duration
31.20 fixed crash paths, Connect IQ UI lag/freezing, course list stability, elevation profile scaling, weather widget values, and overlay menu behavior
31.18 fixed a translation issue that added "Day" to date strings
31.15 added gear tracking improvements and fixed radar color mode, false climb credit, auto zoom, Strava widget freezing, ClimbPro display, shifter summary, course navigation, and recent finds issues

Version 31.22 continues the same stabilization effort on the 31.xx branch.

How to Install Edge MTB 31.22 Beta

Garmin says you need:

Enrollment in the Public Beta Program
A configured Wi-Fi network on the device
To open Main Menu > System > About > Check For Updates

After the download finishes, you may need to manually select Software Update 31.22.

If the device shows "Collecting diagnostics...", Garmin asks users to go to:

Menu > System > Diagnostics > Upload RAM Dump

Should Edge MTB Beta Users Install It?

If you are already on the 31.xx beta branch, yes. This is a focused update that addresses shifter input, map display, and ClimbPro accuracy, all of which matter during trail riding.

Because this is a 50% rollout, the update may not appear immediately. Check again later if it does not show up right away.

Conclusion

Garmin Edge MTB software version 31.22 Beta is a compact maintenance release. It fixes shifter button actions for multi-button configurations, corrects map data field orientation, and improves ClimbPro remaining climb distance on the edit page.

For beta testers, this is a sensible update that improves riding workflow and data trust without introducing a large new feature surface.
