SATELLITE navigation is optional across the X-Type range. Like the audio and climate systems, the sat-nav uses fingertip control via a 178mm (7-inch) "widescreen" colour LCD display. The system uses DVD technology, which according to Jaguar enables eight times the amount of information to be stored onto a single disc compared to conventional CD-ROM based systems. A combination of screen and voice guidance is provided, the latter selectable in nine languages. In addition to the usual destination guidance, the system can provide information and markings of points of interest such as service stations, hotels, car parks, shopping centres, restaurants and hospitals.
