ABSTRACT:
A car stereo set is disposed in a dead space inside a car which can be reached by a person sitting on the rear seat of the car, e.g. a central armrest, side armrest, rear side wall, or the back of a front seat. The car stereo set may be reduced to unit configuration so that it may start a sound reproduction operation immediately when it is inserted into a receptacle formed inside or outside the car. Further, the car stereo set may include a pair of car stereo units (both of which include a tape recorder) and a stereo switching mechanism. When a cassette tape is inserted into the tape recorder of one unit reproduction of the other car stereo unit is interrupted, a cassette tape inside the tape recorder of the other unit is ejected, and a reproduction operation based on the newly inserted cassette is started.
