High line system radio cassette

The high line radio cassette is located in the center of the fascia and contains the radio and tape player. Two clips (accessible through slots in the front of the unit) secure the unit. To remove the radio cassette unit the two clips must be released with a special tool. The high line system can be controlled from the fascia mounted radio cassette, or from remote radio control switches on the left hand side of the steering wheel. In vehicles fitted with radio headphone amplifiers, the rear seat passengers can control their individual audio output using a headphone amplifier control panel. The audio signal can be from the radio, cassette player or a CD-autochanger. A logic control circuit in the radio cassette player controls the operation in the various control modes.
