Description
The Mercedes-Benz A22290503098R73 / A22290519048R73 Switch Blocks are OEM multifunction control modules for the steering wheel, primarily compatible with S-Class (W222) vehicles. These blocks control key steering wheel functions, including media and phone controls, cruise control, menu navigation, and driver assistance system interactions.
