OVERVIEW
The audio system is available in 3 options. The 3 systems all have an AAM.
The 3 systems are:
- Sound system with 7 speakers
- Sound system with 11 speakers
- Surround system with 15 speakers.
The systems are controlled using the FCDIM, the FCIM and the left steering
wheel switch.
The portable media interface panel allows wired connectivity. The level of
connectivity is dependent upon the vehicle
infotainment equipment option.
The front portable media interface panel contains:
- Universal Serial Bus (USB) 2.0 socket
- Type-C socket
- The nano Subscriber Identification Module (SIM) card socket (if
equipped).
Primary user control of the audio system is through the FCDIM and FCIM.
Control signals from the FCDIM are relayed
on an Automotive Pixel Link 2 (APIX2) connection to the IGM / ICCM. The IGM /
ICCM relays the control signals to the
rest of the audio system. The signals are sent through High Speed (HS)
Controller Area Network (CAN) Human
Machine Interface (HMI) systems bus.
Wireless connectivity is made using the Bluetooth antenna.
ACTIVE SOUND DESIGN
Active sound design provides the vehicle occupants with an enhanced engine
sound, digitally reproduced over the
infotainment system speakers.
Audio systems with an AAM receive an engine speed input from the PCM. The engine
speed input allows the audio
system to provide a digital audio enhancement of the engine sound. The enhanced
engine sound is output over the
audio speakers as an overlay to current audio system output.
The system is invisible to the vehicle occupants and is permanently active.
