System Overview: Notes
The Telematics Control Unit (TCU) and the interface box 'High' (ULF-SBX-H) control units are connected to the MOST bus. TCU and interface box 'High' may both be fitted in the vehicle for certain equipment options. In this case, the telephone function is always implemented in the TCU.
The head unit transmits the audio signal in analog form to the HiFi amplifier and the amplifier distributes the audio output to the loudspeakers in the car.
The HiFi system is fitted as standard in the F01/F02.
If the "Top HiFi system" is installed in the car, the audio signal is transmitted digitally on the MOST bus to the HiFi amplifier and the amplifier distributes this signal to all the loudspeakers.
Audio playback of the call recipient is via the front right, front left and center loudspeakers.
For the sake of clarity the various individual loudspeakers are not shown in the schematic circuit diagrams.
The Telematics Control Unit (TCU) used in the F01/F02 is similar to one used in the E70.
The pairing wizard is again integrated in the F01/F02 to assist the customer in pairing the mobile phone.
