Cautions

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.
For Argentine models: Connect the power supply 
lead ʗ to the unit and speakers before 
connecting it to the auxiliary power connector.

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.

Note 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.

Adjust the mounting angle to less than 45°.

*5 Note for the antenna (aerial) connecting (Argentine 

models only): 
If your car antenna (aerial) is an ISO (International 
Organization for Standardization) type, use the 
supplied adaptor ʘ to connect it.

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.

Making connections

If you have a power antenna (aerial) without a relay 
box, connecting this unit with the supplied power 
supply lead ʗ may damage the antenna (aerial).
