The navigation head unit comprises of a 5" full color screen and a control panel designed as an integral unit of the center stack. The navigation module is situated in the luggage compartment on the left-hand side and is covered by a protective trim panel. The Global Positioning System (GPS) antenna is located beneath the parcel shelf trim.

The system utilizes signals from the GPS antenna, the ABS unit and the GYRO sensor's signals to enable the navigation module to calculate, with the aid of CD ROM map data, the position of the vehicle. After entering the required destination, the driver is guided along by both visual guidance and voice instructions. Even, if the driver strays off the route, the system calculates a new route showing the easiest way back to the original destination. On route, it can also point out useful landmarks such as, petrol stations, restaurants, hotels, Jaguar dealers, and car parks.

The system also provides system interfaces such as TV (Japan only), vehicle emergency message system (North America only) or real time traffic information.
