There is a firmware to solve this problem: https://we.tl/t-7vnyWoTWMjI would like to note that in my DVR settings, the display of speed without coordinates is enabled in the menu.
But as we can see in the video, the speed stamp is not displayed. If you turn on the display of speed and coordinates in the menu,
then everything will be displayed. This happens on both firmwares.
Might be a problem with my copy...
I have contacted the Viofo representative but have not received a response yet.
Please download the file from the link and try to update it.
