- single slot CD (compact disc)/DVD (digital versatile disc)/mp3 player and virtual multi-changer
- 40GB HDD storage
- HD Radio receiver (NAS only)
- TSD
- MOST based system.
All sound systems include:
- Auxiliary input - 3.5mm jack plug (MP3)
- MP3-compatible, single slot CD (compact disc) player
- AM / FM / RDS / RBDS radio.
All systems can be specified with
- Bluetooth and audio streaming
- Lo-Line can have a single USB for iPod or memory stick in addition to the 3.5mm jack plug.
Hi-Line and Premium systems can be specified with:
- Hard Drive Navigation system (except Asian markets) with virtual CD (compact disc) multi-changer and single slot DVD (digital versatile disc) for front Touch Screen Display (TSD)
- Interactive Voice (Navigation required)
- Digital audio tuner (DAB) (Europe and Asia only) or Satellite Digital Audio Radio Service (SDARS) receiver (NAS only).
The Lo-Line system comprises an audio head unit and a multifunction display. The head unit has the following functions:
- AM/FM tuner
- single CD (compact disc) player
- integral audio power amplifier
- Bluetooth and audio streaming capability
- optional DAB tuner.
The Hi-Line and Premium systems comprise an Integrated Audio Module (IAM) and TSD. The IAM has the following function:
- AM/FM/RDS/RBDS tuner
- IAM1 - Single CD (compact disc)/MP3 [layer
- IAM3 - single CD (compact disc)/DVD (digital versatile disc)/MP3 player 40GB HDD virtual multi-changer (The 40GB hard drive is used by the audio for storing music and also stores the operating system and files for the navigation system (not applicable to Asian market vehicles).)
- Bluetooth and audio streaming capability.
Digital Audio Broadcasting (DAB) is available for most European and Asian markets and gives access to digital radio channels for better sound quality and enhanced functionality depending on local service availability. The DAB module is located below the RH (right-hand) side of the luggage compartment on High-Line and Premium systems or in the audio head unit on the Lo-Line system. The DAB system receives reception signals from the following sources to ensure optimum signal strength.
- DAB band L antenna located in the roof pod or Sigma pod antenna module
- DAB band III antenna located in the rear spoiler.
For NAS vehicles with High-Line and Premium systems, the digital format adopted is Satellite Digital Audio Radio Service (SDARS) which specifically links to the Sirius network. The system operates in the S-band frequency range, and as a result of the use of satellite transmission, has the ability to provide CD (compact disc) quality audio broadcasts over very large areas (typically continents). The SDARS receiver is located in the RH (right-hand) side of the luggage compartment. The system receives reception signals from the satellite radio antenna located in the roof pod or Sigma pod antenna module. SDARS is not available on Lo-Line systems.
HD Radio Technology is a free digital radio format broadcast available in NAS market. HD Radio digital broadcasts are transmitted alongside the analogue AM and FM signals by stations broadcasting HD Radio signals. The HD Radio receiver is integrated into the AM FM tuner on NAS variants of the IAM.
Primary user control of the High-Line and Premium audio systems is via the Integrated Control Panel (ICP) and the Touch Screen Display (TSD) which are located in the center of the instrument panel. Control signals from the ICP are relayed on the medium speed CAN (controller area network) bus to the IAM. The IAM relays the control signals to the rest of the audio system on the Media Oriented System Transport (MOST) ring. The TSD is the timing master for the MOST ring and also hosts a gateway function between the medium speed CAN (controller area network) bus and the MOST ring.
The primary user control of the Lo-Line audio system is via the ICP and the multi-function display, which are located in the center of the instrument panel. Control signals from the ICP are relayed on the medium speed CAN (controller area network) bus to the multi-function display. The control signals are passed to the audio head unit on a dedicated CAN (controller area network) bus.
