How can I change the outside temperature unit to Celsius in the Audi A6?

I've been trying to figure out how to change the outside temperature unit in my Audi A6 but I can't seem to find the option in the settings. Can someone guide me through the process?

To change the outside temperature unit to Celsius in an Audi A6, first press the 'CAR' button on the control panel. Then, use the navigation buttons to access the 'SETTINGS' menu. From there, you can select 'UNITS' and choose 'METRIC' for temperature. Hope this helps!
