Warning
PLEASE READ THIS MANUAL AND THE 
SUPPLIED “READ THIS FIRST” 
COMPLETELY BEFORE INSTALLING OR 
OPERATING YOUR PERSONAL 
NAVIGATION SYSTEM. IMPROPER 
INSTALLATION OR USE OF THIS DEVICE 
MAY CAUSE ACCIDENT, INJURY OR 
DEATH.
On safety
•Be sure to:
– install the navigation system in a safe place 
where it does not obstruct the driver’s view.
– not install the unit above an airbag.
– place the cables and cradle where they do not 
obstruct driving.
– attach the unit to the cradle properly, 
otherwise the unit may fall.
– clean the surface of the suction cup and 
attachment surface before attaching. When 
installing on the dashboard, clean the surface 
on which the suction cup will be attached. 
Also, confirm that the suction cup is securely 
attached after installation. Otherwise, the unit 
or cradle may fall.
Failure to do so may result in unsafe driving 
conditions.
• Do not apply excessive force to the unit or 
cradle as it may fall.
• Comply with local traffic rules, laws and 
regulations.
• Do not continuously watch the unit while 
driving. It is dangerous and may cause a traffic 
accident.
• If you need to operate the navigation system 
while driving, be sure to stop the car in a safe 
place before operating.
• Do not modify the unit.
• Do not disassemble the unit except when 
disposing of it.
On handling
• Do not let foreign objects get inside the 
connector of the unit, as it may cause 
malfunction.
• When the unit is not in use, turn it off by 
pressing/sliding ?/1. Remove the unit from the 
cradle, then disconnect the car battery adapter, 
otherwise battery drain may result. Note the 
following:
If your car’s cigarette lighter socket is not 
connected to ACC on your ignition switch, 
power will continue to be supplied to the unit’s 
built-in power supply even when the ignition is 
off or the unit is not in use.
• Do not connect any accessory other than those 
supplied or optional.
• Do not expose the unit to fire or water, as it 
may cause malfunction.
• To disconnect a cable, pull it out by grasping 
the plug, not the cable.
• Be sure to remove the unit out of the car when 
leaving your car to prevent theft or high 
temperature damage inside the car.
• Note that the built-in battery cannot be charged 
outside the temperature range 5 – 45 ºC (41 – 
113 ºF).
• Do not leave the unit in high ambient 
temperature as the built-in battery capacity will 
deteriorate, or will become unchargeable.
On GPS
As GPS information is obtained from satellites, it 
may be impossible or difficult to obtain 
information in locations such as:
• Tunnel or underground
• Under a highway
• Between high buildings
• Between tall trees with dense foliage
Note
GPS signal reception may be poor depending on the 
material of the car’s windshield.
Be sure to use the supplied or optional car 
battery adapter or AC adapter, which is 
compatible with the unit/cradle. Otherwise, 
excessive voltage may be applied to the unit/
cradle and may cause smoke, fire, or accident.
For details on optional accessories for your 
model, see “Specifications” on page 12.
