Before Use
■ Start the car engine before use
This mobile navigation system must be used when the ignition key is turned to ON or
ACC. To preserve the battery, it should be used with the engine running whenever
possible. Using the navigation system for a long time with the engine switched off
can cause the battery to run down.
■ Corrects display of current position
The fist time the navigation system is turned on after it is installed (or if the vehicle’s
battery has been disconnected for an extended time) it will not read the vehicle’s
current location correctly. Once it receives GPS signals, the system will display the
vehicle’s correct location.
■ Reading programs after the battery has been tur
ned off
The navigation programs will be deleted if the battery is removed for repairs, etc. If
this happens, in sect the map disc provided into the mobile navigation system and
switch on the engine. The mobile navigation system will automatically load the
programmes and start operating normally again.
■ When driving on rough roads
The mobile navigation system might not operate properly or be able to read map
data from the disc if there is severe vibration caused by driving on rough roads.
■ Handling the GPS antenna
• Do not paint the antenna. This will impair or disable signal reception.
• Remove any object or accumulated snow, etc., from the top of the antenna. It will
reduce reception strength.
• Do not pull the cord when removing the antenna or adjusting its position. This can
cause a short or snap the wires.
■ Operating while driving
The GPS voice navigation system displays the controls disabled during driving in
fainter colors. These controls stop functioning and no message is displayed.
■ Precautions for handling precision machines
Be careful of the surrounding temperature. Using the mobile navigation system at
extremely high or low temperatures can lead to malfunction or damage.
Also note that the unit can be damaged by strong vibration or by foreign objects or
water getting inside.
■ Condensation
Condensation can form on the lens inside the main unit just after the car heater is
switched on in cold weather, for example, leading to malfunction. The main unit will
start working normally again if it is just left alone for about one hour for this
condensation to go away. If normal operation is not restored after several hours,
return the main unit to the store where you purchased it.
■ Map disc
Always replace the map disc with another compatible map disc. Never insert an
incompatible disc. It can damage the main unit.
