Why does the vehicle position icon on the map appear 
slightly off my actual 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?
1.Press the   (Home) icon.
Select Settings  > System  > Sound/Beep  tab.
Turn up  Guidance Volume , if guidance volume is low.
2.Select   and then press the   (Back) icon. Select 
Settings > Navigation  and enable Voice Prompts .
For more details, see the Owner’s Manual.
How do I specify a destination when an entered city or
