For a 2008 R55 Clubman, How can I determine which Radio I have? It is a 6 Channel, AM/FM/CD and has AUX input for USB and iPhone. What Part number is it? I read somewhere it is a DC73LCD but want to confirm? My goal is to find a Replacement LCD display that is pixelating when it is HOT. Everything plays OK just cannot read the display when its been sitting in the Hot Sun. Or if you know of a Part number for the LCD Display that would be Nice!
