AUDIO SYSTEM
The audio system consists of the following components.
 Audio unit
 Antenna amp.
 Glass antenna
 Steering switch
 Front door speakers
 Rear door speakers
 Front squawkers
 Audio display unit
AM/FM Radio Mode
 AM/FM radio tuner is integrated into audio unit.
 When AM/FM radio waves are received by rear window glass antenna, the radio waves are amplified by an
antenna amp. to input them to audio unit. Sound signals are output to each speaker for the audio unit. The
FM sub antenna is installed on the rear window glass and the audio unit is received.
CD Mode
 The audio unit has CD function.
 The audio unit outputs sound signals to each speaker when CD is inserted into the audio unit.
