Navigation System Operation

NAVIGATION SYSTEM OPERATION

The navigation system receives GPS information via the GPS antenna. The GPS signals are used by the navigation computer to calculate the vehicles position. Once the driver has input a desired destination the navigation computer can calculate a route, based on the drivers pre-determined preferences or the default settings in the navigation computer.

The navigation system is accessed by pressing the navigation button at the bottom left hand side of the TSD. The driver will then have the option of on road navigation or off road navigation.

On Road Navigation
On road navigation is initiated by the driver inputting a destination. This can be achieved by:
^ Typing in and address from the TSD.
^ Entering a post code.
^ Choosing a pre-entered address from the address book.
^ Choosing a point of interest from a an area.

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.

Off Road Navigation
The off road navigation route comprises a series of way points which are followed sequentially. Direct point to point guidance is given to the first way point in the route. When the vehicle arrives at the first way point guidance is given to the second way point in the route. This process continues for subsequent way points until the final way point (destination) is reached.

The routes are stored in the non-volatile memory of the navigation computer.

The routes can be entered on the TSD and comprise way points, Longitude and latitude destination and previously stored routes.

The different route guidance screens give the user the information required for direct point to point direction to the selected destination (guidance mode). The same guidance screens are also available even when guidance is not being given (compass mode). All the destination and guidance information is not shown on the guidance screens when in compass mode. When the system is in compass mode with no guidance being given the route title is COMPASS MODE.

4x4i
4x4i Gives the driver additional information regarding vehicle systems.
^ Suspension travel
^ Gear selected
^ Range selected
^ Terrain response
^ Vehicle heading
^ Compass heading
^ Steering wheel angle

The 4x4i System uses inputs from other vehicle systems to display information about suspension and transmission operation along with navigational information.
