1. A radio system for receiving broadcast signals, the radio system comprising:
- at least two antennas picking up radio signals;
at least two signal receivers receiving the radio signals, where the two antennas and the two receivers operate in a plurality of diversity operating modes;
an antenna switching unit for building a connection between the at least two receivers and the at least two antennas;
a control unit for controlling the antenna switching unit and selecting the diversity operating mode; and
a connection to a navigation unit to receive an information data request signal from the navigation unit, the control unit being configured to select from at least one diversity operating mode that enables reception of radio signals encoded with information data, the control unit being configured to receive the information data and to transmit the information data to the navigation unit.
