ABSTRACT:
A navigation device (1) with a housing (2), an antenna (3), forming a part of the device (1), for position signals, an internal conversion unit (11) for evaluating and converting the received position signals into digital position information, a central processing unit (4) with a navigation interface (12) for receiving and for processing the digital position information, and with a data input (8) via which an external receiving antenna (in9) with an external conversion unit (in9) can be connected for generating digital position information, provides for preferred processing of externally formed digital position information in a very simple manner in that the processing unit (4) is preceded by a switching device (13), the output of which is connected to the navigation interface (12) and which switches from the internal conversion unit (11) to the data input (8) when externally formed digital position information reaches the device (1) via the data input (8).
