mph/kph issue

My bad, mine is the same. I forgot the actual options in the Stamp menu. I turned GPS stamp on and it is now showing the correct speed and all in mph.

Where did you get the 20141204 file from? I downloaded a *.7z file which i re-named Firmware.bin but it did not install.

You need to extract the bin file from the .7z file, Google and download 7zip for that.

This problem is a factory fault, now it can not be solved even you update the cam

I've cracked it!

I had the problem of the E-PRANCE dashcam recording Km/H and labelling it MPH. I purchased it as a 0803 but found that it had a resolution setting of ‘2560x1080p 30fps 21:9’ so it was in fact 0805. It had firmware 20141112 v1.0 installed

The Chinese company was useless but I downloaded file 20141204_A7_0805_GPS_1CARD.7z from https://dashcamtalk.com/mini-0805/#Firmware and unpacked it using, open source (free) ‘7z’ tool (Courtesy TerryUK above).

Copied the unpacked files 'firmware.bin' and 'amboot_hal_kernel_romfs_dsp_release.elf' to the chip in my camera (I’m not sure that the latter was necessary).
On start-up I OK’d the upgrade and the problem is cured. The firmware is now version 20141204 and I have a menu item to set the speed units to MPH, Km/H or off. I set it to MPH and it now records the speed, in MPH, more accurately than my speedo which indicates a speed 10% too high.
