Why Buy This Part? The 2002-2006 BMW (E46) 3-Series Business CD radio has the common defect of the volume button breaking loose. Once broken, it makes the on/off feature and volume adjustment from the radio very difficult. The failure is with the white plastic mounting base found within the faceplate of the radio. Alpine Electronics, the manufacturer of this radio, is well aware of the problem and has engineered this upgraded, enhanced replacement part as a solution to the problem. There is no need to buy a replacement radio. The solution is fast and easy with only a simple phillips screwdriver.
