GF82.61-P-0002A Audio 30 APS, Function

GF82.61-P-0002A Audio 30 APS, Function
- with CODE (353) Audio 30 APS







The Audio 30 APS has the following functions:

- Radio
Performance corresponds to an MB radio in the superior class (3/99)
- Navigation system
Performance and function are comparable with the current auto- pilot system (APS) (status 3/99)
- Combined CD player for audio and navigation
- Audio signal processing and amplification with control of optional units, e.g.:
Amplifier for sound system (N40/3) and CD changer (A2/6)
- Digital data bus (D2B) and CAN data bus interface

The system is distinguished by its high degree of integration resulting in optimum compactness. The following components are integrated into the radio and navigation unit (A2/56) :
- CD-ROM drive for navigation and playing audio CD's
- Navigation processor including global positioning system (GPS) receiver and gyrosensor
- Radio with two-tuner technology
- 4-channel power amplifier for vehicle loudspeakers

System interlinkage
The radio and navigation unit (A2/56) is provided with the following components for data exchange with external digital components:

- CAN (A1 - A2/56)
The radio and navigation unit (A2/56) is connected with the instrument cluster (A1) via a separate CAN bus. The difference to the other CAN systems is indicated by the spelling CAN bus (A1-A2/56). The CAN bus (A1-A2/56) allows the following functions:
- Operation of the radio and navigation unit (A2/56) is also possible with the multifunction steering wheel.
- The multifunction display (A1/p13) in the instrument cluster (A1) can display navigation information on the current operating status of the radio and navigation unit (A2/56).

The connection to the CAN bus (A1-A2/56) is only realized on models 208 and 210. (Status 3/99)

- Digital data bus (D2B)
Data can be exchanged between the external audio components, the telephone system and - if present - the voice control system over the D2B bus. This allows control data as well as the actual audio signals (e.g. music from CD changer) to be transferred.

The only additional D2B component presently possible is the CD changer (A2/6) (Status: 3/99)

- K bus (diagnostic interface)
Data exchange is accomplished between the diagnostic interface and the hand-held tester (reading out DTCs and actual values, ...).

The communication between the HHT and all other D2B components is accomplished over the radio and navigation unit (A2/56) diagnostic interface.
