(The battery lead should be always 
powered.)Check the battery wiring in accordance 
with the wiring diagram.
Noise
There is an electromagnetic-wave 
generator such as a cellular phone 
near the unit or its electrical lines.Keep an electromagnetic-wave 
generator such as a cellular phone 
away from the unit and the wiring of 
the unit. In case the noise cannot be 
eliminated due to the wiring harness 
of the car, consult your dealer.
The contact of the ground lead is 
poor.Make sure that the ground lead is 
connected to an unpainted part of the 
chassis securely.
Problem
Possible cause Possible solution
Noise is made in 
step with engine 
revolutions.
Alternator noise comes from the 
car.Change the wiring position of the 
ground lead.

position and its wiring are correct. 
In addition, check to see whether the 
antenna ground is securely connected 
to the chassis.
No power is supplied to the antenna 
amplifi er (when using a fi lm 
antenna, etc.).Check the wiring of the antenna battery 
lead.
The number of auto

Notes on CD-Rs/RWs≥ You may have trouble playing back some 
CD-R/RW discs recorded on CD recorders 
(CD-R/RW drives), either due to their recording 
characteristics or dirt, fi ngerprints, scratches, etc. 
on the disc surface.
≥ CD-R/RW discs are less resistant to high 
temperatures and high humidity than ordinary 
music CDs. Leaving them inside a car for 
extended periods may damage them and make 
playback impossible.
≥ Some CD-R/RWs cannot be played back 
successfully thanks to incompatibility among 
writing software, a CD recorder (CD-R/RW drive) 
and the discs.
≥ This player cannot play the CD-R/RW discs if the 
session is not closed.
≥ This player cannot play the CD-R/RW discs which 
contains other than CD-DA (or MP3/WMA data
                                          ).
≥ Be sure to observe the instructions of CD-R/RW

If the stereo unit functions properly with all these 
connections made, disconnect the wires and 
proceed to the fi nal installation.Final InstallationLead Connections
Connect all wires, making sure that each connection 
is insulated and secure. Bundle all loose wires and 
fasten them with tape so they will not fall down 
later. Now insert the stereo unit into the mounting 
collar.
Congratulations! After making a few fi nal checks, 
you’re ready to enjoy your new auto stereo system.Final Checks1.  Make sure that all wires are properly connected 
and insulated.
2.  Make sure that the stereo unit is securely held in 
the mounting collar.
3.  Turn on the ignition to check the unit for proper 
operation.
If you have diffi culties, consult your nearest 
authorized professional installer for assistance.

Connect All LeadsNow that you have identifi ed all the wires in the 
car, you are ready to begin connecting them to the 
stereo unit wires. The wiring diagram (page 52) 
shows the proper connections and color coding of 
the leads.
We strongly recommend that you test the unit 
before making a fi nal installation.
You can set the unit on the fl oor and make 
temporary connections to test the unit. Use 
electrical tape to cover all exposed wires.Important:
≥ Connect the red power lead last, after you have 
made and insulated all other connections.
Ground
Connect the black ground lead of the power 
connector to the metal car chassis.
Speakers
Connect the speaker wires. See the wiring diagram 
(page 52) for the proper hookups. Follow the 
diagram carefully to avoid damaging the speakers 
and the stereo unit.
The speakers used must be able to handle more 
than 50 W of audio power. If using an optional 
audio amplifi er, the speakers should be able to 
handle the maximum amplifi er output power. 
Speakers with low input ratings can be damaged. 
Speaker impedance should measure 4–8 ≠, which 
is typically marked on most speakers. Lower or 
higher impedance speakers will affect output and 
can cause both speaker and stereo unit damage.
Motor Antenna
Connect the car motor antenna lead to the dark blue 
motor antenna relay control lead.
(Do not confuse the antenna lead with blue/white 
stripe lead for a power amplifi er.)
Battery
Connect the yellow battery lead to the correct radio 
wire or to the battery fuse port on the fuse block.
Antenna
Connect the antenna by plugging the antenna lead 
into the antenna receptacle.
Installation Guide

Identify All LeadsThe fi rst step in installation is to identify all the 
car wires you’ll use when hooking up your sound 
system.
As you identify each wire, we suggest that you label 
it using masking tape and a permanent marker. This 
will help avoid confusion when making connections 
later.
Note:
≥ Do not connect the power connector to the stereo 
unit until you have made all connections. If there 
are no plastic caps on the stereo hooking wires, 
insulate all exposed leads with electrical tape until 
you are ready to use them. Identify the leads in 
the following order.
Power Lead
If your car has a radio or is 
pre-wired for one: 
Cut the connector wires 
one at a time from the plug 
(leaving the leads as long 
as possible) so that you can 
work with individual leads.
Turn the ignition on to the accessory position, and 
ground one lead of the test bulb to the chassis. 
Touch the other lead of the test bulb to each of the 
exposed wires from the cut radio connector plug. 
Touch one wire at a time until you fi nd the outlet 
that causes the test bulb to light.
Now turn the ignition off and then on. If the bulb 
also turns off and on, that outlet is the car power 
lead.
If your car is not wired for an audio unit: 
Go to the fuse block and fi nd the fuse port for radio 
(RADIO), accessory (ACC), or ignition (IGN).Battery Lead
If your stereo unit has a yellow lead, you will need 
to locate the car’s battery lead. Otherwise you may 
ignore this procedure. (The yellow battery lead 
provides continuous power to maintain a clock, 
memory storage, or other function.)
If your car has a radio or is pre-wired for one: 
With the ignition and headlights off, identify the car 
battery lead by grounding one lead of the test bulb 
to the chassis and checking the remaining exposed 
wires from the cut radio connector plug.
If your car is not wired for an audio unit: 
Go to the fuse block and fi nd the fuse port for the 
battery, usually marked BAT.
Speakers
Identify the car speaker leads. There are two leads 
for each speaker which are usually color coded.
A handy way to identify the speaker leads and the 
speaker they are connected with is to test the leads 
using a 1.5 V AA battery as follows.
Hold one lead against one pole of the battery and 
stroke the other lead across the other pole. You will 
hear a scraping sound in one of the speakers if you 
are holding a speaker lead.
If not, keep testing different lead combinations until 
you have located all the speaker leads. When you 
label them, include the speaker location for each.
Antenna Motor
If your car is equipped with an automatic power 
antenna, identify the car motor antenna lead by 
connecting one bulb tester lead to the car battery 
lead and touching the remaining exposed wires 
from the cut radio connector plug one at a time. You 
will hear the antenna motor activate when you touch 
the correct wire.
Antenna
The antenna lead is a thick, black wire with a metal 
plug at the end.
