This kit replaces the blank buttons next to the cruise/LIM buttons on your F2x M Sport steering wheel with M1|M2 buttons from the //M cars and allows them to control the drive modes. The M1 key mimics the 'Sports' button in the centre console and the M2 key mimics the 'Eco Pro' button, allowing you to cycle through the drive modes without taking your hands off the wheel! There is no coding or soldering required and the installation is simple.
