BMW systems


BMW has three basic audio systems – Stereo, HiFi, and Top HiFi/Premium Sound. These sound systems can be controlled by the iDrive navigation system or by the Professional CD player. (In the US, we rarely see the “Business CD” head unit, the E83 X3 being the notable exception).


Example – E90 3-Series sedan with Stereo
