The M button on a dash cam refers to the menu button. Below is more information about dash cams: 1.

Main functions: Self-check function; identification function; recording and storage of driving time, speed, and mileage; overspeed alarm and recording function; overtime driving reminder function; accident suspicious point recording and analysis function; data communication function.
I've encountered this M button issue way too many times! The M button on the dashcam is usually the mode switch button. Pressing it once will toggle the display content on the main interface, like switching from video recording view to photo preview, then to system settings. Some dashcams also use it to switch between recording modes - cycling through normal recording, emergency recording, or parking surveillance mode. Last time when I helped my neighbor adjust their dashcam, holding the M button for two seconds could even turn off the microphone recording function - pretty hidden feature. If you still have the manual, I suggest checking the button instructions page, as this button's functionality varies significantly across different brands. If you're really unsure, you can try pressing it a few times while powered on - just pay attention to the icon prompts in the bottom left corner of the screen. Just be careful not to accidentally format the device by long-pressing it.
