Temperature display changed from Celsius to Fahrenheit by itself
 

I ordered from GB a climate control unit and just when I deployed it on my US car the first time, the display changed from Celsius to Fahrenheit within one minute by itself. I videotaped this feature here

I think the control changes the temperature display automatically, depending on the car. Now it's F permanently.
I have no experience in the reverse case (from F to C) but I think it has to be the same.

neat

Could be still in C, just a sign of how fast global warming is advancing
