Radio AM/FM
| Radio AM/FM |
| General |
The radio receiver is integrated in the head unit. The radio section is an AM/FM receiver with PLL frequency synthesis for exact station tuning (frequency locking).
| Function |
The antenna signal is fed from the antenna amplifier via coaxial cable and a separate connector to the head unit. For further information about the car antenna system see. Antenna system, radio (4D) and Antenna system, radio (5D) .
The radio is activated with the RADIO BAND button on the head unit. When the radio is active information is sent on the bus.
| RDS |
The RDS (Radio data System) is an information system that transmits in parallel with radio programmes on the FM network. The signals from such a FM station make it possible to search for the most powerful transmitter for that particular station and thus to maintain the best reception. The automatic transmission of traffic messages and programme type vigilance are examples of functions made possible through RDS. A precondition for the proper functioning of RDS is the existence of normal reception conditions.
