Navimow H2 Cannot Create a Map: App and Firmware Fixes
Fix a Navimow H2 that cannot create a map by updating the app and firmware, restarting correctly, and preserving useful support evidence.
Reviewed October 13, 2026 by RobotMower.help. Independent guidance checked against the official Navimow source linked below.
Quick answer
Update both the Navimow app and H2 firmware. If mapping still cannot start or save, reinstall the app, restart the mower, and retry once before sending the serial number, versions, phone details, event time, and video to support.
What this problem means
This page targets failure to create the map, not a saved map that later disappears or a boundary that is inaccurate. Navimow’s official process emphasizes software versions, a clean app installation, and one mower restart before escalation.
Fix it in the safest order
- Record whether mapping fails to open, start, complete, or save.
- Update the Segway Navimow app through the official app store.
- Check that the H2 firmware is current.
- Close the app fully and restart the mower.
- If the problem continues, reinstall the app and sign back into the correct account.
- Retry mapping once while recording the exact time and failure stage.
Checks that prevent a repeat problem
- Do not delete an existing usable map unless the task truly requires a new one.
- Confirm you are signed into the account that owns the mower.
- Keep the phone charged and the app open during the mapping attempt.
- Save the app version, phone model, operating-system version, and a video.
How to verify the fix
A successful fix allows the mapping workflow to open, record the intended area, and save the map so it remains available after the app is reopened.
Frequently asked questions
Should I update the app or the mower first?
Both should be current. Check the app and H2 firmware before reinstalling or repeating the mapping process.
Is this the same as a disappeared map?
No. This guide is for being unable to create a map. A map that previously existed and disappeared has a different diagnostic path.
What information does support need?
Provide the serial number, app version, phone operating system, phone model, exact event time, and a video of the failure.
