This car radio is capable of receiving RDS signals (RDS =
Radio Data System) in the VHF range. RDS is a technique
which enables the transmission of inaudible additional infor-
mation in the VHF broadcasting range. This means that the
transmitter broadcasts information which can be evaluated by
the car radio.
