BMW 7 Series: System Overview
GENERAL INFORMATION
The system overview of the F01/F02 audio system begins with a general bus
overview. It shows the
interconnection of all IKT components in the bus system network.
A block diagram of the Car Information Computer is also provided.
Particular reference is made to the individual levels within the CIC head unit:
- User interface
- Application software
- Hardware components
Detailed information can be found in the following pages on the individual
circuit diagrams:
