Cautions
Run all ground (earth) leads to a common ground 
(earth) point.
This unit is designed for negative ground (earth) 12 V 
DC operation only.
Do not disassemble or modify the unit.
Do not install in locations which interfere with airbag 
operation.
Do not get the leads under a screw, or caught in moving 
parts (e.g. seat railing).
Before making connections, turn the car ignition off to 
avoid short circuits.
Connect the yellow and red power supply leads only 
after all other leads have been connected.
Be sure to insulate any loose unconnected leads with 
electrical tape for safety.
Do not press on the LCD when installing the unit.
Install the unit with the monitor facing straight forward; 
do not install it at a slanted angle.
Notes on the power supply lead (yellow)
When connecting this unit in combination with other 
stereo components, the amperage rating of the car 
circuit to which the unit is connected must be higher 
than the sum of each component's fuse amperage rating.
If no car circuits are rated high enough, connect the unit 
directly to the battery.
Connection example  
Notes (
-A)
Be sure to connect the ground (earth) lead before connecting the 
amplifier.
The alarm will only sound if the built-in amplifier is used.
Note (
-B)
You cannot use multiple auxiliary devices simultaneously, even if they are 
connected to different terminals.
Connection diagram  
To a common ground (earth) point
First connect the black ground (earth) lead, then connect the yellow 
and red power supply leads.
To the power antenna (aerial) control lead or the 
power supply lead of the antenna (aerial) booster
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).
If your car has a built-in FM/AM antenna (aerial) in the rear/side 
glass, see “Notes on the control and power supply leads.”
 
To AMP REMOTE IN of an optional power 
amplifier
This connection is only for amplifiers. Connecting any other system 
may damage the unit.
To a car’s illumination signal
Be sure to first connect the black ground (earth) lead to a common 
ground (earth) point.
To the +12 V power terminal which is energized 
when the ignition switch is set to the accessory 
position
Notes
If there is no accessory position, connect to the +12 V power 
(battery) terminal which is energized at all times. 
Be sure to first connect the black ground (earth) lead to a common 
ground (earth) point.
If your car has a built-in FM/AM 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 first connect the black ground (earth) lead to a common 
ground (earth) point.
To the parking brake switch cord
To an auxiliary device such as a portable media 
player, game console, etc. (not supplied)
Tip
You can use an RCA pin cord (not supplied) to connect auxiliary 
devices.
To the +12 V power terminal of the car’s rear lamp 
lead (only when connecting the rear view 
camera)
Notes on the control and power supply leads
REM OUT lead (blue/white striped) supplies +12 V DC when you turn on 
the unit.
If your car has built-in FM/AM antenna (aerial) in the rear/side glass, 
connect REM OUT lead (blue/white striped) 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 supply 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 damage.
Do not connect the speaker terminals to the car chassis, or connect the 
terminals of the right speakers with those of the left speakers.
Do not connect the ground (earth) lead of this unit to the negative (–) 
terminal of a 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 they feature a common negative (–) lead for the right and left 
speakers.
Do not connect the unit’s speaker leads to each other.
Notes on connection
If “Output connection failure.” appears in the display, make sure the 
speaker and amplifier are connected correctly.
To use the monitor for the rear seats, connect the parking brake switch 
cord to the ground (earth).

Precautions
Choose the installation location carefully so that the unit 
will not interfere with normal driving operations.
Avoid installing the unit in areas subject to dust, dirt, 
excessive vibration, or high temperature, such as in 
direct sunlight or near heater ducts.
Use only the supplied mounting hardware for a safe and 
secure installation.
To open/close the front panel smoothly, insert/eject a 
disc easily, and especially to drive safely, a certain 
distance between the front panel and the shift lever is 
necessary. The necessary distance differs, depending on 
the shift lever position of your car. Before installing the 
unit, choose the installation location carefully so that 
you can drive safely.

Connecting the parking brake 
lead  
Be sure to connect the parking brake lead (light green) of 
the power supply connection cable 
 to the parking brake 
switch cord. The mounting position of the parking brake 
switch cord depends on your car. Consult your car dealer 
or your nearest Sony dealer for further details.
Installing the microphone 
(XAV-701BT only)  
To capture your voice during handsfree calling, you need 
to install the microphone 
.
Cautions
Keep the microphone away from extremely high 
temperatures and humidity.
It is extremely dangerous if the cord becomes wound 
around the steering column or gearstick. Be sure to keep 
it and other parts from obstructing your driving.
If airbags or any other shock-absorbing equipment is in 
your car, contact the store where you purchased this 
unit, or the car dealer, before installation.

Removing the bracket  
Before installing the unit, remove the bracket 
 
from the unit.
Insert both release keys 
 together between the 
unit and the bracket 
 until they click.
Pull down the bracket 
, then pull up the unit to 
separate them.
Adjusting the frames  
You can adjust the projecting part of the unit when the 
unit is mounted.
Shift lever
Projecting part
Remove the screws 
 from both sides of the unit.
Choose a screw hole from 
 or 
 on each 
frame 
.
If you secure the frames 
 with the screw holes 
 (default position), 
it will maximize the projecting part of the unit. On the other hand, 
screw holes 
 will minimize the projecting part.
Reattach the frames 
 with the selected screw 
holes with the removed screws 
.
Notes
Choose the same screw hole position on both frames.
If you intend to secure the frames with screw holes 
 or 
, make sure 
that there is enough space in the dashboard of your car for the unit.
Mounting the unit  
-A  Mounting the unit with the supplied 
bracket
Position the supplied bracket 
 inside the 
dashboard.
Bend the claws outward for a tight fit.
Mount the unit onto the supplied bracket 
.
-B  Mounting the unit in a Japanese car
You may be able to install this unit in some makes of 
Japanese cars without the supplied bracket. If you cannot, 
consult your Sony dealer.
When mounting this unit to the preinstalled brackets of 
your car, use the supplied screws 
 in the appropriate 
screw holes, based on your car: T for TOYOTA, M for 
MITSUBISHI and N for NISSAN.
Notes
To avoid a malfunction, install only with the supplied screws 
.
Do not apply excessive force to the buttons of the unit.
Do not press on the LCD.
Before mounting, make sure there is nothing on the top of the unit.
Warning if your car’s ignition 
has no ACC position
Be sure to set the Auto Off function. For details, refer to 
the supplied “Operating Instructions.”
The unit will shut off completely and automatically in the 
set time when no source is selected, which prevents 
battery drainage.
If you do not set the Auto Off function, press and hold 
 until the display disappears each time 
you turn the ignition off.
Reset button
When the installation and connections are completed, be
