OMNIVALEA Radio Volume Knob Button BMW 3 Series E46 Business CD MD 65126924906

This replacement power and volume knob fits the factory BMW Business CD and Business MD radio head units installed in 3 Series E46 models across all body styles, including Saloon, Coupe, Convertible, Touring and Compact. Molded from durable black POM plastic, it replaces the original rotary knob that commonly cracks, loosens or goes missing from the radio faceplate, leaving the volume shaft exposed. It press-fits directly onto the original rotary encoder shaft, restoring full control of power and volume functions with a clean factory appearance.
