Radio Head

The radio head faceplate interfaces with the operator through control buttons/knobs, a Liquid Crystal Display (LCD), a four channel integrated amplifier, and playback mechanisms (CD and/or tape). The controls operate various music modes and conditions of the audio subsystem which enable the operator to control power, volume, fade, balance, bass, and treble equalization settings, along with media playback control (CD or tape). The LCD is located in the center of the radio head faceplate for the operator to see the feedback from the radio. The radio head processes AM or FM stereo signals from the antenna system and sends the output to the speakers. The radio head also processes and plays the pre-recorded music from the in-dash CD and/or tape playback mechanism or the remote CD changer. The tape mechanism is able to differentiate between FeO2 (Type I) or CrO2 (Type II/IV) type tapes. The functions of the playback mechanism (CD or tape) are controlled by the controls on the radio head faceplate.

The radio head is located in the middle of the instrument panel and is fastened using two chassis side-mounted brackets which utilize two fasteners and two rubber pins (one on each side of the radio opening) for locating the radio. The radio head is electrically connected to the radio IP harness via a 24-way connector for base and up-level radios. There is also a 12-way connector for up-level radios to connect the CD changer/player jumper connector. A ground strap terminal and an antenna connector are located on the rear side of the radio head unit. The harness connector(s), antenna connector, and ground strap are inserted prior to mounting the radio in the vehicle. To allow for radio serviceability, sufficient room is allocated behind the radio for the wires and the coax cable.

There are four different radios available: AM/FM stereo with compartment, AM/FM stereo CD with compartment, AM/FM stereo cassette with CD player, and AM/FM stereo cassette with 6 disc in-dash CD player. For more details on these radios, please refer to the "System Checks" and the "Radio Specifications".

The clock time is displayed continuously even when the ignition is Off. Back lighting of the display occurs when the ignition is On. If the RCL button is pressed when the ignition is Off, then the LCD back lighting will be On temporarily.
