The radio is made by Grundig (In the Japanese version: a standard Sony with side-covers for the special shape of the opening).
It has a few (European) RDS (Radio Data System) features:
PS (Program Identification) to display the name of the station
AF (Alternative Frequencies) to switch to stronger frequency of the same station
TP (Traffic Program) to interrupt the cassette when traffic info is being broadcast
EON (Enhanced Other Network) to temporary switch to another station when traffic info is being broadcast on any other station

Furthermore there are the climate controls (AC optional), front- and rear foglights, a little digital clock and a very tiny ashtray.
