 Car Systems Connections
Refer also to the documentation for all other components in the system.
Also see “Connecting Information” on page 12.
• Components listed here except for supplied accessories are available separately. When connecting such
components, be sure to also refer to their documentation.
For specifications and other information on separately available components, contact your dealer.
Prevention of accidents caused by short-circuits
To prevent the risk of accidents caused by short-circuits, connect the power supply leads (red and yellow)
only after all other wiring has been completed, and only with the ignition key in the OFF position.
Otherwise, accidental short-circuiting can lead to electric shock and to serious damage.
When a fuse has blown, check the wiring and locate the cause of the problem before replacing the fuse.
When replacing the fuse, be sure to use only a fuse of the same rating (ampere rating). Using a different
fuse or bridging the contacts with wire is highly dangerous and can lead to serious damage.
Make sure to connect all of the following leads.
Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.
• Connect light green lead to parking brake switch lead of car.
• Connect yellow lead to battery power supply of car.
• Connect red lead to accessory power supply of car.
• Connect black lead to metal point on car chassis.
Do not to mix up the yellow and red leads, as this will cause the memory contents to be lost.
Observe the following precautions.
Otherwise there is a risk of electric shock, damage to the equipment, or malfunction.
• Cover unused connectors with electrician’s tape to prevent accidental contact.
• Route FM/MW/LW aerial cable, bus cable, RCA interconnects, and power supply leads as far apart
from each other as possible, to prevent noise interference.
• Always grasp the connector and do not pull the cable when disconnecting the bus cable or other cables.
Otherwise the cable may become detached.
Notes on the control and power supply leads
• The power aerial control lead (blue) supplies +12 V DC while you select the radio reception or while
you activate the AF (Alternative Frequency), TA (Traffic announcement) function.
• When your car has built-in FM/MW/LW aerial in the rear/side glass, connect the power aerial control
lead (blue) or the accessory power input lead (red) to the power terminal of the existing aerial booster.
For details, consult your dealer.
• A power aerial without 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 key 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 speaker
with those of the left speaker.
• Do not connect the earth lead of this unit to the negative (–) terminal of the speakers.
• 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 wires 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 cords to each other.
