A navigation device for people, which device includes a navigation unit, which has a receiver device for the wireless transmission of data to identify the current geographic position, a communication unit that contains an input unit, especially for the input of a target position, and an output unit, especially for the output of path guidance information, and a computer, especially for route planning, which has a memory with at least one digitized road map and can be connected for data transmission to the navigation unit via the communication unit. The navigation unit, the communication unit, the input unit and the output unit form a portable hardware unit, which is equipped with its own power supply and with a transmitter/receiver unit. The computer for calculating essential portions of the route plan is disposed in a stationary manner outside of the portable unit and is connected to a transmitter/receiver for the wireless transmission of route information between the computer and the portable unit it.
