Abstract: The processor-controlled receiving unit (1) for navigation data, for example, traffic, position and acceleration information, makes possible a particularly easy to install and easy to operate supply of mobile minicomputers and handheld computers with these input data for navigating vehicles with simultaneously optimal receiving features, in particular, in the event this vehicle was not equipped with such a unit during its manufacture. These features are realized by supplying voltage via a double utilization of the antenna signal line, via solar cells, by using special interface combinations between the receiving unit (1), computer (5) and receiving elements (2, 24, 48), and via a bi-directional short-range radio link that uses more than one frequency for transmitting to the computer (5). Other embodiments describe the arrangement inside units, which can be easily exchanged in the vehicle, such as the antenna or vehicle radio receiver or even inside the computer (5) itself.
