The navigation head unit comprises of a 7" full color screen which also provides control of the phone, audio system, climate control vehicle emergency messaging system (VEMS) voice control, and TV. 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 on a 4-door vehicle and beneath the rear spoiler on wagon.

The system utilizes signals from the GPS antenna, speed messages from the instrument cluster, ABS unit and the GYRO sensor's signals to enable the navigation module to calculate, with the aid of DVD 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.

Japanese market vehicles only have a navigation module with integrated voice recognition for control of the navigation system. The Japanese system also has the addition of VICS which provides real time traffic information.
