Functions
What is Navigation?
Navigation is a system that measures the
location of your car and guides you along the
route to the set destination. Your car's location
displayed on the map is measured with the
“GPS” and “Map matching” functions.
GPS(Global Positioning
System)
The system that uses GPS satellites to detect
the location is called “GPS”. The radio signals
from these GPS satellites are received and
the location of one's own car is measured to
within about 30 to 200 meters.
• Measuring your car's location takes about 2
minutes in a location with a good view. The
first time this product is used or it is used
after a long while, it takes about 5 minutes to
measure your car's location. •
The GPS satellites are managed by the
Department of Defense of the United States
of America, which sometimes deliberately
reduces the location precision. When that
happens, the location of your car may not be
displayed in the correct location.
Map Matching
“Map matching” is a function that compares
the route tracking data for your car with the
road configuration in the map data, estimates
the road you are driving on, and displays this
on the map.
CAUTION
• The map displayed for navigation and
the traffic rule information were prepared
based on various types of information
when the map data was prepared, so
they may differ from the actual roads
and traffic regulations. Always follow the
actual roads and obey the actual traffic
regulations.
GPS Antenna
GPS antenna
The location of your car is measured by
receiving weak radio signals from GPS
satellites with the “GPS antenna”.
ADVICE
If the radio signals from the GPS satellite
are blocked, the location of your car may
not be displayed in the correct location, so
observe the following rules.
• Do not paste a mirror type film or shade
film that contains carbon onto the
windshield.
• Do not place anything on or near the
GPS antenna.
• Do not use a mobile phone, PHS,
computer, etc. near the GPS antenna.
