GLOBAL POSITIONING SYSTEM (GPS)
The navigation system receives GPS information via the GPS antenna. The GPS signals are used by the navigation system to calculate the vehicle's position. Once the driver has input a desired destination, the navigation system can calculate a route, based on the driver's pre-determined preferences or the default settings in the navigation system
The navigation system is accessed from the Touch Screen Display (TSD) home menu.
Navigation is initiated by the driver inputting a destination. This can be achieved by:
- Entering an address using the TSD
- Entering a post code
- Choosing a previous destination
- Choosing a point of interest from the map disc database
- Choosing the home location
- Choosing a memory stored location.
The driver is then guided to the destination by a scrolling map display and voice guidance. The display can be varied by scale and display type.
Selection of 'Navigation' on the TSD home menu and subsequent sub-menu selection sends a control request signal to the IAM for Rest Of World (ROW) markets or navigation computer (Japan only) on the Media Oriented Systems Transport (MOST) ring. In Asia markets the TSD control request is passed to the navigation computer via the medium speed CAN (controller area network) bus. The requested control information is processed by the Integrated Audio Module (IAM) for ROW or navigation computer for Japan and Asia only.
On ROW vehicles, if voice guidance is operational, the voice signals are passed from the IAM to the audio power amplifier on the MOST ring for output on the speaker system.
On Japan vehicles, if voice guidance is operational, the voice signal information is relayed from the navigation computer on the MOST to the audio power amplifier for output on the speaker system.
On Asia vehicles, if voice guidance is operational, the voice signal information is relayed from the navigation computer, via an analogue audio signal to the IAM. The IAM converts the analogue signals which are then passed to the audio power amplifier on the MOST ring for output on the speaker system.
The navigation audio output is through the front speakers whilst the background audio, for example radio or CD (compact disc), is played at a reduced volume on the rear speakers. On Asia systems the radio or CD (compact disc) output is paused while navigation audio output is operating.
The GPS signal is available to the navigation system at all times when the vehicle ignition is switched on.
Navigation user voice commands are made using the Land Rover Voice system. The TSD processes the analogue signal from the Land Rover Voice switch. This is passed from the TSD onto the MOST system to the Land Rover Voice control software which is integral with the IAM (ROW) or navigation computer (Japan). Land Rover Voice control of the navigation system is not available on Asia specification vehicles.
The TSD sends an instruction via the MOST ring to the IAM to turn on the microphone facility. The microphone is hardwired to the IAM. For the ROW system, spoken voice commands are processed by the IAM. The processed commands are then sent to the TSD to determine which control signals need to be sent to the Navigation system.
For the Japan system, the analogue voice signals are relayed from the IAM via the MOST ring directly to the navigation computer (for processing). Navigation commands are handled internally within the navigation computer without the need for communicating with the TSD for control.
Traffic data from the TMC or the VICS is processed by the IAM or navigation computer (Japan only), distributed to the TSD with any supporting voice instruction relayed through the MOST ring to either the IAM or audio power amplifier, dependant on equipment level, for output on the speaker system.

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 located in the rear spoiler and the 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 three methods of transmitting the traffic data to the vehicle's navigation system: FM (frequency modulation), microwave RF and infra-red. The microwave and infra-red transmissions are both received by the VICS beacon antenna. The same information is also transmitted on a FM (frequency modulation) wavelength and is received by the FM (frequency modulation) antenna located in the rear spoiler and uses the audio system antenna amplifiers to pass the signals to the navigation module.
The VICS supplies information to enable the navigation computer to re-route the navigation guidance or to inform the vehicle driver of traffic conditions in the vehicles vicinity.
The RF (radio frequency) transmissions are generally transmitted from road side beacons mainly on expressways. The information transmitted is as follows:
- Traffic congestion
- Travel time to next intersection
- Traffic conditions in surrounding areas and expressway turn offs
- Traffic accidents
- Speed limits
- Lane regulations
- Tire change
- Parking availability at expressway service areas and parking areas.
Infra-Red transmissions are transmitted from road side beacons on major trunk roads. The information transmitted is:
- Traffic congestion and travel time
- Traffic accidents
- Breakdowns
- Road works restrictions
- Parking availability.
FM transmissions are broadcast as part of the FM multiplex broadcasting system from NHK (Japanese Broadcasting Corporation) FM stations. Information transmitted is:
- Traffic congestion and travel time for wide areas
- Traffic accidents, road works, speed limits and lane restrictions for a wide area
- Parking availability information.
The traffic data is split from the normal FM transmissions by the FM antenna amplifier module.

OFF-ROAD NAVIGATION

NOTE:
Off-Road Navigation is not available on Asia navigation systems.
Off-road navigation is selected pressing the 'NAV' hard key on the TSD then select the Off-road nav icon.
Off-road navigation maps are similar to the on-road maps but have additional features and information, for example; a large compass display, heading, altitude, latitude and longitude.
When switching to off-road navigation mode during on-road guidance, the current highlighted on-road route will be removed from the map and on-road guidance will be suspended. Way points and destination icons will remain displayed. The destination is marked with a double circle.
When exiting off-road guidance, the system recalculates the route and reverts to on-road guidance.

NOTE:
TMC/VICS is not available during off road navigation.

CO2 OPTIMIZED NAVIGATION

NOTE:
CO2 Optimized Navigation is not available on Asia navigation systems.
When entering a destination, the navigation system give the option to select three routes. When this option is selected, three alternative routes options are displayed on the map.
The roads on the map are shown in three different colors to highlight each route. Leaves are used alongside each of the three calculated routes to indicate the most fuel efficient.
In addition to the color coding, leaf symbols are displayed with three leaves being the most efficient route and one leaf being the least efficient route.





Select route 1, 2 or 3 by touching the respective box displayed on the right side of the map in the TSD.

ADVANCED LANDROVER VOICE CONTROL

NOTE:
Only basic voice controls are available for Japanese specification vehicles. Voice control is not available on Asia specification vehicles.
The Jaguar Voice system provides the driver with the option of voice control for a range of supported functions. In addition to the navigation system, the system also supports the following:
- phone system
- notepad functions
- radio
- satellite radio
- Digital Audio Broadcasting (DAB)
- single CD
- virtual CD autochanger
- USB and auxiliary connection functions.
The Land Rover Voice system adopts a concept known as 'Say What You See' (not applicable to Japan specification vehicles). Each of the Land Rover 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 TSD 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.
The 'notepad' facility allows voice notes to be recorded. Nametags for radio tuning, phone dialing and navigation locations allow the system to be personalized and there is a help and tutorial function to provide advice on using the system.
Land Rover Voice is a key component of the navigation system, allowing hands free control when issuing navigation commands.
The system is controlled by the voice button on the LH (left-hand) side of the steering wheel. Voice commands are picked up by a dedicated microphone. When giving a voice command, audible feedback will be heard through the vehicle's audio speakers.
