Navigation system and control unit for navigation system
First Claim
1. A navigation system for a vehicle comprising a mobile navigation computer, a vehicle-based central control unit, a GPS receiver, a communication link between the mobile navigation computer and the central control unit, wherein position data for the vehicle is processed in a navigation unit in the mobile navigation computer to form information relevant to the navigation, wherein in the course of the navigation the relevant information is transmitted from the navigation computer to the control unit for a respective maneuver which is to be performed, and wherein this information is output in at least one of visual and audible forms via the central control unit, wherein the position data for the vehicle is determined by the position-finding unit of the central control unit, using at least one of the GPS receiver associated with the central control unit and at least one sensor associated with the central control unit, and is transmitted to the mobile navigation computer, wherein the vehicle is navigated on the basis of the relevant data calculated for the navigation from the transmitted position data in the navigation unit of the mobile navigation computer.

Abstract
A navigation system for a vehicle including a mobile navigation computer, a vehicle-based central control unit, a GPS receiver, a communication link between the mobile navigation computer and the central control unit, wherein position data for the vehicle is processed in a navigation unit in the mobile navigation computer to form information relevant to the navigation. The navigation information is transmitted from the navigation computer to the control unit for a respective maneuver which is to be performed, and this information is output in at least one of visual and audible forms via the central control unit. The position data for the vehicle is determined by the position-finding unit of the central control unit, and is transmitted to the mobile navigation computer, wherein the vehicle is navigated on the basis of data calculated in the navigation unit of the mobile navigation computer.
