A navigation unit, especially for vehicles, with a data bus (3), with a data memory (2) on which a plurality of map information items and navigation data are stored, with a navigation computer (1), connected to the data bus (3), for route planning, with a data processing unit (30), connected to the data bus (3), for processing the data into picture information, the data processing unit (30) containing a picture memory (32) for storing the picture information, with a monitor (4), connected to the data processing unit (30), on which the picture information can be displayed, with a communication block (20) with a control unit (21) for entering the start location, intermediate destination, and/or final destination of a trip, such that the data processing unit (30) contains a map memory (38) for storing road map information.
A navigation unit, especially for vehicles,
The navigation unit of one of the preceding claims, characterized in that the communication block (20) contains a control unit (21) for entering a user request (B) to change the current picture information.
The navigation unit of one of the preceding claims, characterized in that the communication block (20) contains a traffic data receiver (22) to receive current traffic information.
The navigation unit of one of the preceding claims, characterized in that the sensor block (10) to acquire position data is associated with the navigation computer (1).
The navigation unit of one of the preceding claims, characterized in that the data processing unit (30) has a control unit (39) to manage and process the road maps stored in the map memory (30).
The navigation unit of one of the preceding claims, characterized in that the data bus (3) is an MOST bus or an MML bus.
The navigation unit of one of the preceding claims, characterized in that the navigation computer (1) and the data processing unit (30) are implemented with two separate μ processors.
The navigation unit of one of the preceding claims, characterized in that two or more independent data processing units (30, 30a, 30b) and monitors (4, 4a, 4b) display independent map sections.
