yea man!! i had a problem with that too!! mine is canadian c350 4matic, just go to instrument cluster settings, then scroll down to 'outside temperature' or w/e its called and click 'OK' while it is highlited on the temperature seting. then it will change to,miles per hour or somthing, and then yea then u can see the speed in miles per hour in the screen that showed km/h speed, it'll show both speeds, in km/h and mph but the mph will be in little numbers. but yea

hope u find this usefull
