ABSTRACT:
In a vehicular radio receiver having a decoder for decoding digitally encoded received traffic announcements, a memory device for route-specific characteristics and a visual and/or acoustical output device for the traffic announcements are provided. The output is effected by the readout of information from the memory device. To output not only factual information but detour recommendations as well, place names and detour route names are stored in the memory device in jointly addressable memory fields. In transmitting the encoded traffic announcements it is then possible to allow or suppress the output of the already stored detour recommendations only on the basis of a control signal.
