Navigation System: Description and Operation: Overview

Navigation System

OVERVIEW
The navigation system provides audible and visual route guidance information to enable the driver to reach a desired destination. The system allows the driver to choose the route using minor or major roads or highways with the option of three routes. Directions to hospitals, museums, monuments and hotels are also available.
The navigation system is integrated with the audio/video system and shares a number of components common to all systems. Map information is stored on a hard disk drive located in the Integrated Audio Module (IAM).
The system is new to the 2010MY Jaguar XJ model and uses a hard disk drive to store the navigation data, removing the requirement of a luggage compartment mounted navigation computer used on previous Jaguar models.
The navigation system uses the following components:
- Integrated Audio Module (IAM)
- Integrated Control Panel (ICP)
- Dual-view Touch Screen Display (TSD)
- Sigma pod for GPS antenna
- Instrument cluster.
The dual-view TSD allows the front seat passenger to view television and video images when the car is being driven. The dual-view screen allows the driver to see the navigation or other system screens but not the TV or video when the vehicle is moving. The screen can be switch between single and dual view using a switch on the ICP.

NOTE:
Due to legislation, the NAS markets do not receive this dual-view option.
Japanese market vehicles have a modified system from other markets. The Japanese specification vehicles have a navigation computer and a navigation module located in the luggage compartment. This is in addition to the Vehicle Information and Communication System (VICS) beacon antenna located on the top of the instrument panel on Japanese specification vehicles.
