Overview

Garmin has released Software Version 31.31 for the Edge MTB. The stable firmware update is currently listed at 20% rollout, so it may appear gradually through Garmin Express or Garmin Connect Mobile.

Unlike the other Edge 31.31 releases, the Edge MTB changelog includes an additional connectivity fix. It also includes the same corrupted-map crash fix and incident detection fix seen across the wider Edge 31.31 stable rollout.

  • Announcement Date: June 23, 2026 (UTC)

What's New in Version 31.31?

Edge MTB Connectivity Fix

  • Fixed connectivity issue on Edge MTB.

This is the device-specific item in the Edge MTB 31.31 changelog. Garmin does not provide more detail in the forum post, but the wording confirms that 31.31 addresses a connectivity problem unique to the Edge MTB release.

Map Corruption Crash Fix

  • Fixed crash when maps are corrupted.

Mountain bike rides can put extra pressure on navigation reliability because trails, forks, and reroutes may need quick decisions. A crash caused by corrupted maps can interrupt that workflow, so this stability fix is useful for trail-focused riders.

Incident Detection Reliability Fix

  • Fixed incident detection not triggering in some cases.

Garmin also includes the incident detection fix in the Edge MTB 31.31 changelog. The update should improve behavior in affected cases where incident detection did not trigger as expected.

Why This Update Matters

A Specific Fix for Edge MTB Owners

The connectivity fix makes the Edge MTB release more than a direct copy of the other Edge 31.31 updates. If you have seen pairing, sensor, phone, or wireless behavior that felt unreliable, this version is worth installing when it reaches your device.

Garmin's note does not identify the exact connectivity path affected, so the safest reading is broad: 31.31 contains a connectivity correction for Edge MTB, but riders should still verify their own sensors and phone connection after updating.

Better Trail Navigation Stability

The corrupted-map crash fix is also important on a mountain bike computer. Trail navigation depends on quick map access and stable route context, especially when riding unfamiliar networks or following a preloaded route.

How to Get the Update

Garmin says Edge MTB Software Version 31.31 can be downloaded through Garmin Express or Garmin Connect Mobile when available.

Because the rollout is currently at 20%, the update may not show up for every Edge MTB immediately.

Should Edge MTB Owners Update?

Yes. This stable release includes three practical fixes, including one Edge MTB-specific connectivity issue. Edge MTB owners should install Software Version 31.31 once it appears in Garmin Express or Garmin Connect Mobile.

Conclusion

Garmin Edge MTB Software Version 31.31 is a worthwhile stable update. It fixes an Edge MTB connectivity issue, improves handling of corrupted maps, and corrects incident detection behavior in some cases.
