yellow, and red power supply leads.
To the parking brake switch cord
Be sure to connect the parking cord (light green) to the
parking brake switch cord. The mounting position of the
parking brake switch cord depends on your car. Refer to
“Connecting the parking cord” on the reverse side and
consult your car dealer or your nearest Sony dealer for
further details.
To the power antenna (aerial) control lead or
power supply lead of antenna (aerial) booster
amplifier
Notes
• It is not necessary to connect this lead if there is no power
antenna (aerial) or antenna (aerial) booster, or with a
manually-operated telescopic antenna (aerial).
• When your car has a built-in FM/MW/SW antenna (aerial)
in the rear/side glass, see “Notes on the control and power
supply leads.”

amplifier
This connection is only for amplifiers. Connecting any other
system may damage the unit.
To the interface cable of a car telephone
To the +12 V power terminal which is
energized in the accessory position of the
ignition key switch
Notes
• If there is no accessory position, connect to the +12 V
power (battery) terminal which is energized at all times.
Be sure to connect the black ground (earth) lead to a
metal surface of the car first.
• When your car has a built-in FM/MW/SW antenna (aerial)
in the rear/side glass, see “Notes on the control and power
supply leads.”
To the +12 V power terminal which is
energized at all times
Be sure to connect the black ground (earth) lead to a metal
surface of the car first.
Notes on the control and power supply leads
• The power antenna (aerial) control lead (blue) supplies +12 V
DC when you turn on the tuner.
• When your car has built-in FM/MW/SW antenna (aerial) in the
rear/side glass, connect the power antenna (aerial) control
lead (blue) or the accessory power supply lead (red) to the
power terminal of the existing antenna (aerial) booster. For
details, consult your dealer.
• A power antenna (aerial) without a relay box cannot be used
with this unit.
Memory hold connection
When the yellow power input lead is connected, power will
always be supplied to the memory circuit even when the ignition
switch is turned off.
Notes on speaker connection
• Before connecting the speakers, turn the unit off.
• Use speakers with an impedance of 4 to 8 ohms, and with
adequate power handling capacities to avoid its damage.
• Do not connect the speaker terminals to the car chassis, or
connect the terminals of the right speakers with those of the
left speaker.
• Do not connect the ground (earth) lead of this unit to the
negative (–) terminal of the speaker.
• Do not attempt to connect the speakers in parallel.
• Connect only passive speakers. Connecting active speakers
(with built-in amplifiers) to the speaker terminals may damage
the unit.
• To avoid a malfunction, do not use the built-in speaker leads
installed in your car if the unit shares a common negative (–)
lead for the right and left speakers.
• Do not connect the unit’s speaker leads to each other.
Note on connection
If speaker and amplifier are not connected correctly, “FAILURE”
appears in the display. In this case, make sure the speaker and
amplifier are connected correctly.
