FIELD: physics, navigation.

SUBSTANCE: invention relates to a vehicle navigation system. The navigation system includes a vehicle, an information display (40) fitted in the vehicle, a portable GPS unit (10) and an interface (30) for transmitting data between the portable GPS unit and the information display fitted in the vehicle. The information display (40) is mounted on the vehicle and is visible to the driver. The portable GPS unit (10) includes a GPS sensor for determining location of the GPS unit and a portable information display (20). The portable GPS unit (10) is fitted in a positioning unit in the vehicle such that the portable information display is visible to the driver. Data from the portable GPS unit (10) can be displayed on the information display fitted in the vehicle. In the first version, the portable GPS unit (10) includes a central processing unit (15) for storing several locations. The information display (40) fitted in the vehicle and the portable information display (20) display different information on location of the GPS unit relative the stored locations. An input device (50) is designed for transmitting a signal from the portable GPS unit (10) through the data transmission interface (30). The input device (50) is fitted as an alternative solution on the information display (40) fitted in the vehicle or is fitted such that the driver can operate it without taking hands off vehicle control elements. The input device (50) is designed for transmitting a signal to the portable GPS unit (10) for storing the location of the GPS unit in the central processing unit (15). In the second version, the information display (40) fitted in the vehicle displays data from the portable GPS unit (10) when receiving data from the data transmission interface (30) and displays data from a sensor fitted in the vehicle when the data transmission interface (30) and the portable GPS unit (10) are interrupted.

EFFECT: easy vehicle control.
