Safety precautions

2WARNING

To prevent injury or fire, take the
following precautions:

• Insert the unit all the way in until it is fully
locked in place. Otherwise it may fall out of
place when jolted.

• When extending the ignition, battery, or ground
wires, make sure to use automotive-grade
wires or other wires with a 0.75mm2(AWG18)
or more to prevent wire deterioration and
damage to the wire coating.

•To prevent a short circuit, never put or leave
any metallic objects (such as coins or metal
tools) inside the unit.

• If the unit starts to emit smoke or strange
smells, turn off the power immediately and
consult your Kenwood dealer.

2CAUTION

To prevent damage to the machine, take
the following precautions:

• Make sure to ground the unit to a negative 12
V DC power supply.

• Do not open the top or bottom covers of the
unit.

• Do not install the unit in a spot exposed to
direct sunlight or excessive heat or humidity.
Also avoid places with too much dust or the
possibility of water splashing.

• Do not subject the faceplate to excessive
shock, as it is a piece of precision equipment.

• When replacing a fuse, only use a new one
with the prescribed rating. Using a fuse with
the wrong rating may cause your unit to
malfunction.

•To prevent short circuits when replacing a fuse,
first disconnect the wiring harness.

• Do not use your own screws. Use only the
screws provided. If you use the wrong screws,
you could damage the unit.

Cleaning the Unit

If the faceplate of this unit is stained, wipe it
with a dry soft cloth such as a silicon cloth.
If the faceplate is stained badly, wipe the stain
off with a cloth moistened with neutral cleaner,
then wipe neutral detergent off.

2CAUTION

Applying spray cleaner directly to the unit may
affect its mechanical parts. Wiping the
faceplate with a hard cloth or using a volatile
liquid such as thinner or alcohol may scratch
the surface or erases characters.

Lens Fogging

Right after you turn on the car heater in cold
weather, dew or condensation may form on
the lens in the DVD player of the unit. Called
lens fogging, DVDs may be impossible to play.
In such a situation, remove the disc and wait
for the condensation to evaporate. If the unit
still does not operate normally after a while,
consult your Kenwood dealer.

If everything is in order, press the reset button. If the
unit does not seem to be working right, try pressing
the reset button first.

Kenwood dealer.

The Mark Position of Your Car Immediately After Installation

•Immediately after installation, the information of the GPS satellite is taken in and it may take
several minutes to measure the position of the current location.

• Immediately after installation, the initial value setting of the gyro sensor is required. After
measuring the position of the current location, drive of about 6.2 mile (10 km) and further at a
constant speed at least 24.8 mile/h (40 km/h) in a place where there are few obstacles (for
example, buildings and tree-lined streets).

NOTE

• Until the initial values are set, the position and speed indication of you car's mark on the navigation
system may differ greatly from the actual values.

• The proper connection of the car speed signal wire can be checked with the menu screen. Please
see the instruction manual for details.
