Hi, new Smart fan buying Brabus ForFour when it becomes widely available in UK after Christmas. Unfortunately new model uses a fixed scale for climate control not an LCD which can be switched for scale and SMart are selling cars with Metric measurements not British in UK except speedo.. It seems other markets have a basic ac option (seems stupid to pay for something you are not going to use. Has anyone tried swapping the scale or the Climate Control head unit (N22/1) replacing a Centigrade model with Fahrenheit or vice versa? I notice many manufacturers are doing away with the LCD's presumably to save money? Any experience very welcome. Smart do not answer such questions and I want to know if it can be done without voiding warrnaty before buying car from UK dealer. I see in the manual that the Display head unit has settings for temps, units of distance and volume. Are these user configurable or does it require the dealer software? Thanks everyone.
