Why does the vehicle position icon on the map appear 
slightly off my actu al position, especially at intersections?
This is normal. The navigation system is unaware of the 
width of intersections. Large di fferences in vehicle position 
can indicate a temporary loss of the GPS signal.
Why does the “Arrival time” display sometimes increase 
even though I am getting closer to my destination?
The “Arrival time” is based on the speed limit on each 
road. Depending on the traffic conditions, the “Arrival 
time” may be calculated  to be earlier or later.
Why does my clock frequently change the time forward 
and backward by one hour?
The clock setting is automatically updated based on your 
GPS location. If you are driving near a time zone border, 
the automatic update likely is the reason.
How do I turn on the navigation system voice guidance?
●Adjust the volume using the volume knob during the 
voice guidance.
●Press the   button.
Select  Settings  > System  > System Vol
 umes > 
System Volumes .
Turn up volume level of  Navi
 gation On Guidance if it 
is low.
How do I specify a destination when an entered city or 
street could not be found?
Try selecting the destinat ion directly from the map.
