Role of main components
–Multimedia network interface unit: enables information to be exchanged between the "vehicle" and "multimedia"
multiplex networks.
The multimedia network interface unit receives various signals from the vehicle CAN (speed, status of exterior
lights) and retransmits them for the radio via the Multimedia CAN.
The multimedia network interface unit transmits the activation signal to the radio and to the other computers
participating in the multimedia function when the user switches on the radio or starts the vehicle.
–Display: displays various multimedia system data such as the station selected, time, CD listing and satellite
guidance information.
–Steering column switch: provides access to various functions of the multimedia system.
–Speakers: relay the sound from the multimedia system into the vehicle.
–CD changer: enables compact discs to be loaded and music to be relayed to the receiver.
–AM/FM aerial: receives radio signals.
–GPS aerial: receives various data transmitted by satellites.
–Radio/navigation computer: manages the various multimedia system functions according to user requests and
transmits audio data to the vehicle via the speakers.
–AM/FM aerial amplifier: improves the reception of AM and FM signals.
