Audio program
The audio systems in the BMW 1 Series are divided into 3 levels:

The audio systems differ in that various sound pressures can be achieved or there is improved system linearity. The stereo system consists of 6 loudspeakers; the HiFi system or top-hifi system consists of 10 loudspeakers and various additional amplifiers. The central bass speakers are located under the front seats.

Antennas
Rear-window antennas and a roof-mounted antenna are used in the E87. The rear-window antennas deliver the signals for the reception of FM. The roof-mounted antenna receives the signals for the telephone, FM and AM. Antenna diversity is fitted on the Radio Business CD and Radio Professional or higher. Antenna diversity contains the antenna amplifier. Antenna diversity switches the antennas for FM.
