Is it possible to switch the odometer reading from KM to miles?

 

Sure. Push the button above the radio on/off button. Turn **** of that button one click to highlight "comp" (computer) and press **** again. Use same procedure to set distance, km per liter etc. When you finish then your speedomeer should read everything or some things (depending on what your choices were) in km.

 

What is the year/model of your car? You posted in the 1st generation forum. In 1st generation models (R50/R52/R53), km/miles selection is not user accessible, but it can be programmed by a dealer or by using NCS Expert software.
