SYSTEM DESCRIPTION
1. Outline

As a unique feature of Rear Seat Entertainment (RSE) system, the front and rear seat occupants can
enjoy different audio±visual modes at the same time. Thus, this system offers enhanced entertainment
to the rear seat occupants.

The rear seat occupants can control the audio±visual modes with the remote controller (switch assy),
and listen to audio by using wired or wireless headphones.

The RSE system is controlled by the multi±display controller, and the communication among the audio
head unit, rear display assembly, and DVD player is established via an AVC±LAN (Audio Visual Com-
munication±Local Area Network).
2. Function of Main Component
Television Display Assy

Displays DVD and video images in accordance with video signals from the RSE ECU.

Receives signals from the remote controller and outputs them to the RSE ECU.

Outputs audio signals to the wireless headphones in the form of infrared signals.

Displays the audio±visual control screen.

Speed signal circuit
CIRCUIT DESCRIPTION
The navigation ECU (built in the radio and navigation assy) receives a vehicle speed signal from the com-
bination meter assy and information about the GPS antenna, and then adjusts vehicle position.
HINT:

A voltage of 12 V or 5 V is output from each ECU and then input to the combination meter. The signal
is changed to a pulse signal at the transistor in the combination meter. Each ECU controls the respec-
tive system based on the pulse signal.

If a short occurs in an ECU, all systems in the speed signal circuit will not operate normally.

TONE AND BALANCE
For details about your system's tone and
balance controls, see the description of
your own system.
Tone
How good an audio program sounds to
you is largely determined by the mix of
the treble, midrange, and bass levels. In
fact, different kinds of music and vocal
programs usually sound better with differ-
ent mixes of treble, midrange, and bass.
Balance
A good balance of the left and right stereo
channels and of the front and rear sound
levels is also important.
Keep in mind that if you are listening to
a stereo recording or broadcast, changing
the right/left balance will increase the vol-
ume of one group of sounds while de-
creasing the volume of another.YOUR RADIO ANTENNA
Your vehicle has an antenna printed on
the inside of the rear quarter window.
NOTICE
Attaching the film (especially conduc-
tive or metallic type) on the rear
quarter glass will noticeably reduce
the sensitivity of the radio.
YOUR CASSETTE PLAYER
When you insert a cassette, the exposed
tape should face to the right.
NOTICE
Do not oil any part of the player and
do not insert anything other than cas-
sette tapes into the slot, or the tape
player may be damaged.
YOUR COMPACT DISC PLAYER (type 1)
When you insert a disc, gently push it in
with the label side up. (The player will
automatically eject a disc if the label side
is down.) The player will play from track
1 through the end of the disc. Then it will
play from track 1 again.
NOTICE
Never try to disassemble or oil any
part of the compact disc player. Do
not insert anything other than com-
pact discs into the slot.
The player is intended for use with 12 cm
(4.7 in.) discs only.
