Hi there, I have a 2025 GLC 300 4Martic Coupe, I am from Europe but I live in USA and I'd like to switch the temperature units from Fahrenheit to Celsius.
It's not possible to do it from the MBUX in the car, and the dealer tells me they cannot do it, because "at the dealership it's only on European spec that allows the switch sadly".
They recommended I try OBD and an app like MBito, but that particular one seems to not support the 254 model yet.

Does anyone know of another app/device/approach to achieve that?

<rant> How is it possible that a luxury German vehicle, produced in Austria and sold worldwide, cannot be switched to metric units?!?! You can do that on a Prius with several clicks in the menus.... </rant>

 

Under settings > vehicle - There should be a manual option. Same applies to K/M to MPH
