TRAFFIC MESSAGE CHANNEL (TMC)
NOTE:
TMC is not available in all markets.
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 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, depending on the type of road. In certain areas the information is transmitted using an infra-red signal or alternatively an RF microwave signal, both of which are received by a VICS beacon antenna located on the top of the instrument panel. Additional information is also transmitted on a FM (frequency modulation) wavelength and is received by the FM antenna integral with the rear windshield. The received FM signal is then passed to the navigation module, via an RF antenna amplifier.
ADVANCED JAGUAR VOICE CONTROL
NOTE:
Only basic voice controls are available for Japan specification vehicles.
The Advanced Jaguar Voice system provides the driver with the option of voice control for a range of supported functions. In addition to the navigation system, phone system and the notepad functions, the system also supports radio, satellite radio, Digital Audio Broadcasting (DAB), single CD, hard disk drive, USB and auxiliary connection functions.
The Advanced Jaguar Voice system adopts a concept known as 'Say What You See' (not applicable to Japan specification vehicles). Each of the Advanced Jaguar Voice functions are supported by 'Help' commands, saying 'Help' at each point in the conversation will give a context sensitive explanation of what the user can do at that point. The voice menu shown in the instrument cluster always guides the user through the flow showing not only examples of what they can say next, but also confirmation of where they are in the conversation flow.
Push to talk button and Instrument Cluster Prompt Menu
To start a voice session the driver presses the push to talk button briefly. An audible tone can be heard, followed by the presentation of the voice command list in the instrument cluster. A voice symbol alongside each item in the list indicates that the system is listening for one of the available commands. Always wait for the listening tone before using the command. To end a session the same button is pressed and held
Voice control is mainly a software based system. The software responsible for controlling the voice system is resident in the following control modules:
- Integrated Audio Module (IAM) (All markets except Japan)
- Navigation module (Japan markets only)
- Touch Screen Display (TSD)
- Instrument Cluster
Some of these modules contain more than one software component. Voice control communication between these modules takes place via the MOST network. A voice control microphone is located in the front overhead console and is hardwired to the IAM.
When the push to talk button is pressed on the steering wheel, a voltage is received at the TSD via the clockspring assembly. This voltage is sent on a single wire from the button, through a resistive ladder. The whole process is then initiated via the MOST network, for example the prompt menu list is held in the TSD but presented in the instrument cluster. The accompanying voice instruction is sent to the audio amplifier for broadcast over the speakers from the IAM. If a recognized user instruction is received via the microphone this is then processed and sent to the TSD to perform the required action.
NOTE:
Should an instrument cluster priority message be required this will prevent or cancel the current voice session.
Voice Tags
Voice tags allow the user to store voice entries as shortcuts to control various functions, for example routing to navigation locations, dialing numbers and tuning to radio stations. The voice tags sub-menu accesses controls for navigation, phone, radio and depending on specification DAB radio or SDARS.
Voice Training
The voice system allows two different users to create separate profiles, providing training for a User 1 and User 2. Voice training is used to help the system recognize the user's voice more accurately, and when training is activated for each user, a pop-up is displayed to confirm that training is in process for that user. The pop-up informs the user that voice training must be fully completed in order to activate the new voice profile, and offers the option of 'OK' to initiate the session and store data in that User profile, or 'Cancel' to return to the previous menu. Once activated, another pop-up indicates that training is in progress. Voice training phrases will be shown in the 'Instrument Cluster Voice Menu' and the user will be requested to say each phrase after the listening tone.
NOTE:
Voice training can only be conducted stationary with the engine running and with the climate control NOT in defrost due to background noise.
Voice tags and training are stored in a non-volatile memory within the IAM. Disconnection of the battery would not cause any customer data loss.
NOTE:
To enable new voice tags and training to be written to memory, a period of ten minutes after the last key off cycle must take place. Should the battery be disconnected before this time then data may be lost.
NOTE:
If the IAM was to be replaced then all voice tags and training would be lost.
NOTE:
If either the IAM, Instrument Cluster or the TSD are replaced, it is recommended that the vehicle language settings and voice language settings (if vehicle language is not supported by voice control) are reset to the same setting.
Navigation Destination Entry by Voice
Destination entry uses phonetic transcriptions of the navigation data (stored as part of the map data) to offer the user the ability to enter an address or postcode into the Navigation system by voice. The user simply follows the visual and audible instructions given by the voice system and enters their desired address in a step-by-step manner (e.g. city, then street, then house number). At each address entry stage, the user's voice command is matched against the phonetic map data and a list of likely recognition candidates is presented in a "picklist" for the user to select from. If the chosen address has more than one location associated with it, the voice system will work with the user to determine the exact address they wish to navigate to.
Dialing from the G2P Phonebook
Provided the phonebook has been downloaded via Bluetooth, the voice system is able to perform a grapheme-to-phoneme (G2P) transcription of each of the names stored in the phonebook. This is then used by the voice system to allow the user to dial a contact by saying the name stored in the phonebook, there is no need to store a voice tag first. The user's voice command is matched against the phonebook entries and a list of likely recognition candidates is presented in a "picklist" for the user to select from. If the chosen contact has more than one number associated with it, the voice system will work with the user to determine the exact number they wish to dial.
NOTE:
For regularly used contacts with more than one number, the user can store a voice tag as a shortcut.
INTEGRATED AUDIO MODULE (IAM)
NOTE:
The Japanese satellite navigation system does not store map data on the IAM. All other functions of the IAM are applicable to Japan market. Refer to 'JAPANESE NAVIGATION SYSTEM' section below for details of the Japanese navigation system.
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), steering wheel mounted control switches or by voice commands.
The 40 GB hard drive is used for storing the information for satellite navigation. 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 Japanese satellite navigation system uses the standard system components, with the exception that the map data is not stored on the IAM hard disc drive. Additional components are: a navigation computer module and a navigation video interface module are used to read the map data and output audio and video signals to the TSD, IAM and audio amplifier.
Navigation Computer Module
A separate navigation computer module is located below the rear windshield parcel shelf.
The module is a DVD drive which reads map data direct from a DVD. The navigation computer module is connected on the MOST ring and communicates with the TSD to initiate navigation video and audio output. The GPS (global positioning system) antenna is connected directly to the navigation computer module.
The navigation computer module outputs the video signals in a Gigabyte Video InterFace (GVIF) format to a navigation video interface module which converts the GVIF input to a Low-Voltage Differential Signalling (LVDS) video signal output which is then passed to the TSD. Audio output is on the MOST ring to the audio amplifier. VICS FM transmission signals are received by the navigation computer module via an FM antenna and a VICS antenna amplifier. Infra-red VICS transmissions are also received by the VICS beacon antenna, located on the top of the instrument panel, and are passed to the navigation computer module.
Navigation Video Interface Module
The navigation video interface module is located in the rear LH (left-hand) corner of the luggage compartment. The video interface module is required to convert the GVIF video output to LVDS video signal which is compatible with the TSD.
A 5V signal output from the TSD is connected to the video interface module. The signal voltage initiates a power up of the video interface module when the TSD is active.
ASIAN NAVIGATION SYSTEM
Navigation Computer Module - Asia
In some markets an after market navigation system is fitted at Pre-Delivery Inspection (PDI) by the dealer or at Port of Entry (POE). A medium speed CAN (controller area network) based navigation computer module is fitted in the LH (left-hand) side of the luggage compartment of the vehicle.
The navigation computer module outputs the video signals in a LVDS format direct to the TSD. Audio output is passed to the IAM which converts the signals and passes them to the audio amplifier on the MOST ring. When Audio is required, such as a Voice guidance instruction, the Asia navigation computer module communicates to the vehicle audio system using a hard wire connection between the TSD and the Asia navigation computer module. Touch screen co-ordinates and vehicle power mode status is obtained through the medium speed CAN (controller area network). Map data is stored via a multimedia Secure Digital (SD) card accessible through an access point on the module.
