Radio reception 

The window antenna amplifier module 2 (A2/72) and the window antenna amplifier module 3 (A2/73) receive the frequency-modulated and the amplitude-modulated radio frequency signals, filter the frequencies of the radio wavebands and amplify them. The amplified radio frequency signals are then relayed to the radio receiver via a coaxial cable.

The radio receiver is included in the audio gateway, which is integrated into the radio and navigation unit (A2/56). The radio receiver demodulates the radio frequency signals, i.e. it separates the signals from the radio frequency carrier. The audio gateway amplifies the audio signals.

IMPORTANT In South America and in Australia the radio receivers for long wave and short wave are deactivated using STAR DIAGNOSIS.

There are 10 radio station presets for each frequency band.

Tuning the radio:

The following functions, which are displayed on the screen of the radio and navigation unit (A2/56), are also available:

Radio data system 

As well as the radio program, many radio stations also transmit non-audible digital information such as the station name, the program type and traffic program identification.

This information is evaluated by the radio and navigation unit (A2/56) and displayed on the screen, provided that the following requirements are fulfilled:

IMPORTANT To protect against overheating of the sensitive components, a fan is fitted under the radio and navigation unit (A2/56).
