I have changed the speedometer from black and white to colour. It is somehow plug and play.
Just make sure that the speedometer is the right one. If your car has ACC, buy one for ACC (or from a car that has ACC). If not, buy the one without.

My car hasn't got ACC and the speedometer was on a car with ACC. I had some troubles to code that option out. I don't know why, all the other coding went smooth.
You will need to change them at a dealership since all the speedometers have component protection. this can only be activated by them online.


Note: The ODO will show the km from the new dashboard!!!
