I just got my c300 two weeks ago and have found one minor, yetvery annoying, problem. On my 2005 c230 I just traded in, I could choose to set the permanent display to show either the Mph or the Temperature. Thepermanent display on my c300 will also allow me to set either the Mph or Temperature .However, the c300 has an option to choose to display Mph or Km/h but when I select Mph, it still shows me Km/h. I find this to be very annoying as I have come accustomed to viewing the Mph in the tiny permanet display section so I do not have to change the main display each time I enter the car.

I have not taken this issue to the dealer yet because I thought I might be missing something here. Anybody else experienced this same issue, or might know how to resolve it?
