On installation
• Before installing the unit, check your local traffic
laws and regulations.
• Make sure you install the unit properly according
to the installation instructions. Improper
installation may result in fire or electric shock.
• Before installation, be sure to turn the ignition
switch to the OFF position or take out the key.
Installing the unit with the ignition on may cause
the car battery to drain or short circuit.
• For information about the polarity, battery voltage
and location of the airbag in your car, please
consult your car dealer.
• When installing the unit, use only the hardware
provided and avoid mounting to any critical
components of the vehicle.
• Take care to prevent cords or wires from getting
tangled or crimped in the moving portion of a seat
rail.
Mounting location
• Do not install the cradle where:
– it will obstruct the driver's view when the cradle
is mounted in the car, or the unit is in the cradle.
– it will obstruct the operation of the airbag
system.
– it will obstruct the operation of the car,
especially the steering wheel, shift lever, or
brake pedal.
– it will be subjected to heat/high temperature.
• Please consult a qualified technician or service
personnel if you cannot attach the cradle to the car
securely.
On GPS
GPS (Global Positioning System) satellites
continuously emit signals for positioning anywhere
on the earth. As a GPS antenna receives these
signals, users can be informed of their location
(latitude, longitude and altitude). Information must
be received from 3 satellites in order to obtain two-
dimensional fixes (latitude and longitude), and 4
satellites are required for three-dimensional
positioning (latitude, longitude and altitude). As
GPS satellites are controlled by the U.S. Department
of Defense, a deliberate margin of error between a
few meters (a few feet) and 10 meters (32.8 feet)
exists. As a result, the GPS navigation system may
include an error of between 10 meters (32.8 feet)
and about 200 meters (656.2 feet), depending on the
circumstances.
As GPS information is obtained using signal from
satellites, it may be impossible or difficult to obtain
the information in the following locations:
• Tunnel or underground
• Under a highway
• Between high buildings
• Between tall trees with dense foliage
After the initial installation, park your car in a safe,
open place (no high buildings, etc.) for up to 20
minutes to allow for GPS signals to be received
before using the navigation system. The system
requires signals from a minimum of 3 GPS satellites
to calculate the current car position properly.
Note
It takes time to receive a GPS signal when switching
the unit ON after switching OFF the main power, after
the built-in battery is fully discharged, or after resetting
the unit.
