N87/3 Digital Audio Broadcasting control unit
Location
The Digital Audio Broadcasting control unit is located in the trunk on the equipment bridge in front of the spare wheel well.
Task
The Digital Audio Broadcasting control unit has the following tasks:
Receive signals
Decoding of signals
Transmit signals
Receive signals
The input factors are read in via the following connection:
Direct lines
Media Oriented System Transport (MOST)
(model 204.0/2 as of 1.3.2011, model 204.3, model 204.9 as of 1.6.2012)
On model 204.0/2 as of 1.3.2011, on model 204.3 and on
model 204.9 as of 1.6.2012 the Digital Audio Broadcasting control unit is designed as a double tuner.
-----------------------------------------------------------------------------------------
Direct lines
The Digital Audio Broadcasting control unit is equipped with the following direct connections:
- Wake-up
- Multifunction antenna (A28/11) (Digital Radio (DAB) L band signals, up to 30.11.2010)
- TV 1 and DAB band III antenna amplifier (A94/1) (model 204.0)
- DAB Band III antenna amplifier (A95/2) (model 204.2)
- FM 2 and DAB antenna amplifier (A/19) (model 204.3)
- FM 2, DAB and TV 1 antenna amplifier (A94/1), via the TV antenna splitter (A2/89) (model 204.9)
On vehicles as of 1.12.2010 DAB-L band signals are not processed and the multifunction antenna is not required for DAB

Media Oriented System Transport (MOST)
(model 204.0/2 as of 1.3.2011, model 204.3, model 204.9 as of 1.6.2012)
- FM signals from audio equipment (for optimum reception-dependent switchover of DAB to FM)
Decoding of signals
The Digital Audio Broadcasting control unit decodes the
DAB L band signals (up to 30.11.2010) and DAB band III signals to obtain pulse code modulation (PCM) signals.
Transmit signals
The Digital Audio Broadcasting control unit sends signals over MOST to the audio equipment:
- DAB status
- Station lists
- Audio signals
