2D/3D GPS reception
The GPS receiver uses signals from satellites to calculate its current
position (the user's position), but to acquire a 3D position at least four
signals are necessary, including altitude. The GPS device may not be
able to acquire signals from four satellites as they are constantly moving
and obstacles may block satellite signals. Although the accuracy
decreases when only three signals can be acquired, and altitude data
cannot be sent, the receiver can calculate a latitude and longitude GPS
position. Only 2D reception is possible.
Route being navigated
The route currently being navigated. When a destination is set, the
route will be continuously navigated until the destination is deleted,
you arrive at the destination, or the software is closed. Also see “Route”.
City center
The center of the city/town is not the geographical center of the city/
town, but a location set by the cartographer. In towns and villages, this
is usually the most important intersection, while in larger cities it is
selected from multiple important intersections.
Color design
The color design used for the map and menu screens differs for daytime
and nighttime. Each design has a different graphic setting, with 2D and
3D each having colors for roads, blocks, seas, and lakes, whilst shadow
changes and shadows are displayed differently in 3D mode.
Daytime screen and nighttime screen designs for the map and menu
are selected one at a time. The design changes automatically when day
becomes night and night becomes day.GPS accuracy
Various factors can contribute to a margin of error between the user's
actual position and the position acquired from the GPS device. For
example, signal delays in the ionosphere or reflections from objects
around the GPS equipment, can influence the accuracy with which the
GPS device can calculate the user's position.
Maps
Although this software uses digital maps, these are not simply digital
conversions from printed maps. The 2D mode digital map represents
roads in the same way as a traditional printed map, using color
classifications to show streets, roads, and changes in altitude.
In 3D mode, you can confirm differences in altitude for mountains,
valleys, highland roads and so on, and display areas of cities using 3D
landmarks and 3D images of buildings.
The digital map can be used interactively. You can zoom in and out
(enlarge/reduce), tilt up and down, and rotate left and right. By using
navigation that supports GPS, you can easily plan your route with the
digital maps.
North Up Map Direction
North Up mode rotates the map so that North is always at the top of
the map. You can use this direction with Find On Map and so on. Also
see “Heads-up Map Direction”.

Glossary
Route
The route is an ordered arrangement of the route events (the next
change in the route - right or left turns, roundabouts, and so on),
presenting them as they occur until you reach your destination. If there
is one starting point, there must be at least one destination. On startup,
the start point is the current position (or the last confirmed position). If
you need to check a route that is not currently being driven, you can
move the start point to wherever you want.
Heads-up Map Direction
Heads-up mode rotates the map so that the direction you are currently
traveling is always at the top of the map. This is the default direction in
3D map display mode. Also see “North Up Map Direction”.
Glossary
To enhance your enjoyment of this product, please familiarize yourself
with the following terms.
•GPS (Global Positioning System)
GPS is a system that detects the current location (latitude, longitude,
altitude) by receiving radio waves from 4 or more GPS satellites in
normal situations, or sometimes from 3 satellites.
These satellites are launched and managed by the US Department of
Defense mainly for military use, but they are also open for private
use. This unit performs navigation using GPS information, various
sensors, and road map data.

•Wide area map, detailed map
The wide area map is a map of a large area, and the detailed map is a
map of a small area. The scales of the maps are 1/20,480,000,
1/10,240,000, 1/5,120,000, 1/ 2,560,000, 1/1,280,000, 1/640,000,
1/320,000, 1/160,000, 1/80,000, 1/40,000, 1/20,000, 1/10,000, and
1/5,000.
•Positioning
The quality of the GPS positioning is displayed in the top right of the
menu screen. The greater the number of displayed symbols, the
higher the precision of the GPS positioning.•2D positioning and 3D positioning
GPS calculates positions using triangulation.
The distance to the satellite can be determined when the radio wave
from that satellite is received, and the current location can be
measured by receiving radio waves from 3 satellites.
However, because there is a margin of error in the GPS satellites and
navigation unit, positioning is performed in only the 2 dimensions of
latitude and longitude when radio waves from only 3 satellites can
be received. The precision will be lower in this case. When radio
waves from 4 or more GPS satellites are received, positioning is
performed in the 3 dimensions of latitude, longitude, and altitude.
3D positioning is more precise than 2D positioning, and it reduces
the margin of error in the vehicle location display.

Further Information
NOTE•Because the GPS satellite is in orbit around the earth, the reception status for
the electromagnetic waves changes depending on their position at that point
in time, even if your vehicle is in the same place. Also, electromagnetic-waves
from satellites near the horizon can be easily influenced by surrounding
obstacles.
•At times, satellites under the control of the US Department of Defence will
intentionally drop positioning accuracy.
Regarding Errors in Current Position Display
The system displays the vehicle current position based on GPS
information and data from various sensors and road maps. However,
when the radiowave signals from GPS satellites are weak or when
signals are received only from two satellites or less, errors may occur in
the position. Modifying or adjusting the system will not prevent these
errors.

Regarding Vehicle Position Detection
Correction Using Map Matching
Map matching is a method of comparing information on the current
position acquired by GPS and so on, with the road driven up to that
point, and correcting the current position based on the most likely
road.
This unit uses information on the current position combined with
independent navigation and satellite navigation and matches it to the
shape of the road to create the correction.
However, as it cannot avoid the error margins at the current position,
the current position may shift away from the actual position even when
correcting using map matching.
Also, the vehicle marker may shift if the map data and the shape of the
road being driven on differ.
NOTE
Because it takes a short time for operations to stabilize just after turning on the
unit, the vehicle mark may not immediately match the vehicle as it moves. After
driving for a while, operations stabilize, and the marker should match the actual
driving position.
Regarding the Accuracy of the Current Position
and Route Navigation
As in the following images, an accurate display of the current position
or route navigation may not be provided, however this is not an
indication of a malfunction in the unit, but is due to road conditions or
driving conditions.

Further Information
Regarding Roads and Place Name Data
Because road and place names may change after the map data has
been created, there may be times when road and place names do not
match.
When no information is available in the map data, function such as
display of road names, searching for facilities, and route guidance
cannot be used.
When maps are created, land surveys are conducted and information
about roads improvement and opening is collected to provide the
most accurate information possible. However, modifications in roads,
place names and facilities may be carried out at any time.
Consequently, we cannot guarantee that map data contains no errors
in road positions, configuration and names, or in facility names.
The navigation system includes a function to read out names of roads,
intersections, and so on during guidance.
Depending on the selected language, names read out by the system
may not be exactly accurate due to missing information in map data.
Regarding Route Navigation
• It may deviate from the route
navigation when there is a turn at an
intersection etc., and a mistake in the
voice navigation.• When searching for the route, it may
take the long way around.
• The route may need you to make a
U-urn during navigation.• When driving on a straight road,
information may be displayed
indicating that you should go
straight ahead. ( When the
intersection shape is not clear and so
on.)

Further Information
•Performing a new search while traveling at high speeds may take
some time.
•The route may not change even after performing another search.
•When isolated locations or roads with no surrounding available
information are set as the current position/destination, you may not
be able to search for a route.
•A route may not be displayed when the current position is close to
the destination.
•Even if you select toll roads as a priority, the route may not guide you
through a toll road.
In a similar way, toll roads may be displayed even if you prioritize
other roads over toll roads.
( When it is possible to select a toll road or a normal road to create
the route, priority is given to the user's toll road preference - use toll
roads, or avoid toll roads.)
• The navigation may not indicate that
the road curves at an intersection.• The navigation may guide you back
to a waypoint if you search for the
route again after passing the
waypoint and are heading to your
destination.
• Many place names may be displayed
when navigating a district.• Always drive by following the actual
traffic regulations.
• When searching for a route, it may not be displayed quick enough for the next
left or right turn.
