Reserving Mode（Show panoramic image when reversing）:
NOTE:
If you feel like you cannot estimate distance when reversing/image is zoomed in when reversing
That’s because the G840S is a streaming dash cam. For better visual effect, the image is enlarged by 1.5 times. And this function is used to assist reversing.
PS: We have a new reversing firmware that displays panoramic images when reversing, if you want, please select the firmware “reserving mode”.
