ˎ Run all ground (earth) leads to a common 

ˎ Do not get the leads trapped under a screw, or 

caught in moving parts (e.g., seat railing).

ˎ Before making connections, turn the car ignition 

off to avoid short circuits.

ˎ Connect the yellow and red power supply leads 

only after all other leads have been connected.

ˎ Be sure to insulate any loose unconnected leads 

with electrical tape for safety.

ˎ Choose the installation location carefully so that 

the unit will not interfere with normal driving 
operations.

ˎ Avoid installing the unit in areas subject to dust, 

dirt, excessive vibration, or high temperature, 
such as in direct sunlight or near heater ducts.

ˎ Use only the supplied mounting hardware for a 

safe and secure installation.

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.

Adjust the mounting angle to less than 45°.

*1 Not supplied
*2 Speaker impedance: 4 – 8 Ω × 4
*3 RCA pin cord (not supplied)
*4 Depending on the type of car, use an adaptor for a 

wired remote control (not supplied).

*5 Whether in use or not, route the microphone input 

cord such that it does not interfere with driving 
operations. Secure the cord with a clamp, etc., if it is 

installed around your feet.

You can use a subwoofer without a power amplifier 
when it is connected to a rear speaker cord.

Note
Use a subwoofer with an impedance of 4 to 8 ohms, 

and with adequate power handling capacities to avoid 
damage.

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.

ɞ To a common ground (earth) point

First connect the black ground (earth) lead, then 
connect the yellow and red power supply leads.

ɟ 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.

ɠ To the +12 V power terminal which is 

energized when the ignition switch is set to 
the accessory position
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.

ɡ To the power antenna (aerial) control lead or 

the power supply lead of the antenna (aerial) 
booster
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).
To AMP REMOTE IN of an optional power 
amplifier
This connection is only for amplifiers and a 
power antenna (aerial). Connecting any other 
system may damage the unit.

ɢ To a car’s illumination signal

Be sure to first connect the black ground (earth) 
lead to a common ground (earth) point.

ˎ Before connecting the speakers, turn the unit off.

ˎ Use speakers with an impedance of 4 to 8 ohms, 

and with adequate power handling capacities to 
avoid damage.

To capture your voice during handsfree calling, you 
need to install the microphone 

ʚ. 

ˎ It is extremely dangerous if the cord becomes 

wound around the steering column or gearstick. 
Be sure to keep it and other parts from interfering 
with your driving operations.

ˎ 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.

Before attaching the double-sided tape 

ʛ, clean the 

surface of the dashboard with a dry cloth.

ˎ Refer to the support sites on the back cover for 

details, then connect each lead properly to the 

appropriate leads. Making an improper connection 
may damage the unit.

ˎ Depending on the type of car, be sure to insulate the 

unused leads with electrical tape for safety.

ˎ Do not connect this cable when the steering wheel 

remote control is not used.

ˎ Consulting the dealer or an experienced technician 

for help is recommended.

To enable the wired remote control, set [STR 

CONTROL] in [SET STEERING] to [EXTERNAL] 

Installation of the connection cable RC-SR1 (not 
supplied) is required before use.

To enable the steering wheel remote control, select 

[SET STEERING] 

q [STR EDIT] to make the 

registration (page 17).

When the registration completes, the steering wheel 
remote control becomes available.

Before installing, make sure the catches on both 
sides of the bracket

dashboard, then bend the claws outward 
for a tight fit.

When replacing the fuse, be sure 
to use one matching the 
amperage rating stated on the 
original fuse. If the fuse blows, 
check the power connection and 
replace the fuse. If the fuse blows 
again after replacement, there 
may be an internal malfunction. In such a case, 
consult your nearest Sony dealer.

Note
To prevent malfunction, install only with the supplied
