If the R7M freezes while you are riding, first check what is frozen. A fully black or unresponsive screen is not the same as bike data or the Wonder Wheel stopping while the touchscreen still works. The latest firmware can still show that second symptom, so do not treat an update as the only fix.
Match the symptom
The whole screen is black, or the display does not respond: use If the screen goes black or an OTA update fails. The R7M and R7X share the same recovery package.
While you are riding, bike data or the Wonder Wheel stops, but you can still use the touchscreen: even on the latest firmware this can still happen. Follow What to do if your RiderNav display lags, freezes, restarts, or crashes and send a debug log. Updating firmware alone may not fix it.
An OTA update is stuck, but the screen still works: use How to update RiderNav firmware (OTA) or Manual firmware update via SD card (R7M).
Check your firmware version
You can still check which firmware you are on, and update if you want the latest version. That does not replace a debug log when data or the Wonder Wheel stops and touch still works.
Go to Settings → About.
To update, follow How to update RiderNav firmware (OTA).
Note: OTA updates require an SD card. Daily riding does not.
