TRAFFIC MESSAGE CHANNEL (TMC)
The TMC is a specific application of the FM (frequency modulation) Radio Data System (RDS) used for broadcasting real-time traffic and weather information. Data messages are received and decoded by the IAM. The IAM processes the received information and alerts the driver and offers alternative route guidance to avoid the incident.
Each traffic incident is sent as a TMC message. One message consists of an event code and a location code in addition to time details. The message is coded and can be translated by the IAM into the market language. Location code tables assign numbers to locations on the road network. Those location tables are integrated in the maps stored on the IAM hard disk drive. The source of traffic information is typically police, traffic cameras and local network stations.
The TMC system uses the existing FM (frequency modulation) antenna integral with the rear windshield and audio system antenna amplifiers to pass the signals to the IAM.

VEHICLE INFORMATION AND COMMUNICATION SYSTEM (VICS) - JAPAN ONLY
The VICS is a similar system to the TMC used outside of Japan. VICS is a unique to Japan and give countrywide coverage and broadcasts of real-time traffic and weather information. The VICS has two methods of transmitting the traffic data to the vehicle's navigation system. In certain areas the information is transmitted as an infra-red signal which is received by a VICS beacon antenna located on the instrument panel. The same information is also transmitted on a FM (frequency modulation) wavelength and is received by the FM antenna integral with the rear windshield and uses the audio system antenna amplifiers to pass the signals to the navigation hard disk drive, via the IAM.

INTEGRATED AUDIO MODULE (IAM)





The IAM is located in central position in the instrument panel, behind the Integrated Control Panel (ICP).
The IAM is a multi functional unit which has the following systems and features:
- Radio tuner
- Compact Disc (CD) player (single slot)
- Hybrid Digital (HD)
- Bluetooth(R) receiver (telephone and audio streaming) Radio (where fitted)
- 40 GB Hard drive (Navigation and audio)
- USB controller (front)
- Audio AUX
- DVD player (audio and video).
The IAM is connected on the MOST ring to the other audio system components. The driver can control navigation functions by using soft keys on the Touch Screen Display (TSD) or steering wheel mounted control switches.
The 40 GB hard drive is used for storing the information for satellite navigation and music files. A 10GB partition is provided for storing music files, the remaining 30GB is used for map data storage.
Hard Disc Drive
The integral hard drive for the navigation system removes the requirement of a separate navigation computer usually found in the rear luggage compartment. The IAM stores the navigation map data locally within the 30GB hard drive partition. By storing the information in this way and processing it within the IAM, navigation display, route calculation speeds and accuracy are vastly improved. Map upgrades and software now have to be loaded directly into the IAM from a CD (compact disc).
The map images are transmitted from the IAM to the TSD via a Low Voltage Differential Signal (LVDS) link cable. Turn by turn instructions are also available, these are displayed in the instrument cluster via a second LVDS link between the instrument cluster and TSD.
The IAM communicates on the MOST ring with the rest of the audio system. If the IAM is replaced it must be configured as a new module using an approved Jaguar diagnostic system
Calibration of the IAM using an approved Jaguar diagnostic system enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.

DUAL-VIEW TOUCH SCREEN DISPLAY (TSD)
The TSD is mounted centrally in the instrument panel. The dual-view TSD enables the passenger and driver to view completely different images from their respective seating positions. This technology has provided a solution for the legal issues attached to viewing moving images whilst the vehicle is in motion. It is not possible for the driver to view moving images with an active speed signal but the passenger can.

NOTE:
Due to legislation the NAS markets will not receive this option. A single view display is available in these markets.
The dual-view TSD uses Parallax Barrier Shutter Technology to alternately hide and reveal columns of pixels to the left and right hand views of the screen. The display comes with a specially designed agar coating to help prevent sunlight bleaching.









To access a TV or video image when the vehicle is in motion and single view is selected, the dual view button should be pressed by either the driver or the passenger. This will then switch the TSD to dual-view mode allowing the passenger to view TV or video, but not the driver. A second press of the button will change the TSD back to single view.

Before and after dual view key activation









Once dual-view has been selected, the driver can change the current screen without affecting the passengers view by pressing any of the keys on the TSD.
The audio system can only broadcast one audio source. Therefore, the TV / video source that is current for the passenger will also be the audio the driver can hear. If headphones have been specified as an option, then the passenger's can choose to listen to the sound source accompanying the TV / video. This allows the driver to listen to a different audio source or navigation commands via the vehicle speaker system.
The driver's view is also event driven, i.e. if reverse gear were to be selected the rear view camera will be displayed automatically, overriding the displayed navigation or other information. The passenger can choose to see the camera image by pressing the dual-view button to change the TSD display to single view.

SIGMA POD









The navigation system GPS (global positioning system) antenna is located in the sigma pod and is shared with the audio DAB L-band antenna where fitted. The sigma pod is located internally in a central position towards the top of the rear window.
The antennas fitted to the Sigma pod MUST be 2mm from the glass when they are fixed/slotted into the Sigma pod carrier which is bonded onto the rear screen. Both the air gap and fixed position in the carrier are extremely critical to the functionality, operation and efficiency of all the sigma module antennae.

JAPANESE NAVIGATION SYSTEM
The VICS navigation is fitted in Japan at PDI (pre-delivery inspection). The system comprises a separate Alpine 30GB hard disk drive navigation module, vehicle to navigation unit gateway module, an alternative FM radio receiver and the VICS beacon. Refer to installation guide supplied at PDI (pre-delivery inspection) for details and fault finding information.
The navigation module is connected using an Ai-Net network to the gateway module. The gateway module converts the Ai-Net network signals to a medium speed CAN (controller area network) bus connection to the TSD.
