Is it possible to change the Additional Speedometer (highlighted) to display in MPH

Think you'll find its a legal requirement to have dual mph/kph displayed.

On my 2018 GLC300, I did change the secondary speedometer to MPH so that I have both, I don't remember exactly how I did it but it was in one of the settings that you change by using the steering wheel buttons, I believe you'll find it under the settings tab.

I also go this problem, if it can change to mph then will be perfect
