Navigating on the Map
In the navigation menu startup screen, the currently active map is
reduced and displayed in (Show Map).
To enlarge the map, touch (Show Map) to open the Map
screen.
This map shows the current position (shown as the vehicle marked as a
blue arrow), recommended routes (orange lines), and the immediate
surrounding area.
When GPS positioning is not active, the vehicle marker is clear. The
latest confirmed position is displayed. Colored spots are displayed on the circle around the satellite icon in the
top left corner. The more spots ther
e are on the circle, the higher the
accuracy of the GPS positioning.
When GPS positioning is active, the ve hicle marker is displayed in full-
color, and the current position is shown.

Buttons and data fields are displayed on the screen, and you can
perform navigation. During navigati on, route information is displayed
on the screen.
The data fields display differs wh en no destination is set during
navigation (no orange line is displayed). When performing navigation,
the number of the data fields displa yed on the screen is three. Up to
two data fields can be displayed when no destination is set (no orange

Field Explanation
(Altitude) Shows the altitude of the road currently being
driven and measured by the GPS receiver.
( There may be a maximum ±50 m of differences
depending on the rece
ption status of GPS
satellites.)
(Time) Displays the current time corrected using the
time zone offset. Accurate
time is acquired from
the GPS satellite, while ti me zone information is
acquired form the map. You can also make
manual settings in Units and Formats.
(Only for the Menu screen, the current time is
shown in the bottom left corner of the screen.)
Field Explanation
(Distance)* Displays the distance on
the route to the final
destination.
(Time Left) Displays the time left un
til arrival at the final
destination based on th e information available
for the remainder of the journey. This is
calculated according to prior traffic data or
traffic patterns when ever available.
If a TMC receiver is connected to the main unit
and is receiving data, an y traffic jams along the
route are also factored into calculations.
However, the accuracy of these calculations
varies greatly.

* Time and distance to the destination cannot be displayed when your vehicle is located in the place other than roads and Highways. After the vehicle returns
to a road or Highway, time and distance are displayed.
Position Marker
■Vehicle Marker and Lock-on-Road
If GPS positioning is available, the current position is shown using the
vehicle marker. • When any vehicle is selected, the vehicle marker may not display an
accurate GPS position and direction of travel. If there is a road nearby,
the GPS positioning error is corrected based on the shortest distance
to the road to, and the direction of the icon is adjusted to match the
direction of the road.
■ Selected map location (cursor)
Use one of the following methods to mark a map location.
• Touch the map during navigation.
• Touch the map when the destinatio n you want is displayed in the
search results.
• Touch the map in “Map Search”. (See Page 134 .)
After selecting a map location, a cu rsor is displayed at the point
selected on the map. The cursor is displayed as a red point ( ) and can
be checked at all zoom levels.
You can use the cursor's position as the route's destination, search for
locations around the cursor, and save the position in the destination list.
(Arrival
Time)* Displays the estimated arrival time at the final
destination based on the information available
for the remainder of th
e journey. This is
calculated according to prior traffic data or
traffic patterns when ever available.
If a TMC receiver is conn ected to the main unit
and is receiving data, any traffic jams along the
route are also factored into calculations.

Check Current Position (Where Am I?)
You can open this function from the Quick menu. The button on this
screen searches for information on th e current position (if there is no
GPS reception it uses the last co nfirmed position) and recommended
spots in the area, and disp lays them on the screen.
This screen provides the following information. • , :
Latitude/Longitude (Current positional coordinates use the WGS84
land survey system)
• :
Altitude (Advanced information acquired by the GPS receiver - may
not be accurate)
• :
Address of current position on left
• :
Address of current position on right
• The latest location information is displayed in the center of the
screen, or the time after the latest information was acquired is
displayed. (Load

Online Road Information Saved in Route Search
This unit can provide you with even better routes, if real-time traffic
information ( TMC: Traffic Message Channel) is available.
If public traffic data is broadcast at your location, this unit automatically
takes into account the traffic data received. You do not need to set
anything in the program. The decoded information will immediately be
used in route planning. The moment unit receives traffic information
that may affect your route, the program recalculates the route, and this
unit will continue with a new route that is optimal based on the most
up-to-date traffic conditions.
Icon Explanation
The software is not connected to the GPS receiver. Cannot
perform GPS navigation.
Products with a built-in GPS receiver are always connected. This
icon is not normally disp layed for those products.
Although the software is connecte d to the GPS receiver, the signal
is too weak to measure the GPS.
Cannot perform GPS navigation.
Only a few satellites are transmitting. Positional information is
available, but altitude (elevati on above sea level) cannot be
calculated.
GPS navigation is possible, but large positional errors may occur.
Elevation above sea level is available, and measurements can be
performed in 3D.
GPS navigation is available.

Glossary
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 alti tude. The GPS device may not be
able to acquire signals from four sate llites as they are constantly moving
and obstacles may block satellite signals. Although the accuracy
decreases when only three signals ca n be acquired, and altitude data
cannot be sent, the receiver can ca lculate 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 navigate d 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 th e geographical center of the city/
town, but a location set by the cartog rapher. In towns and villages, this
is usually the most important intersec tion, 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 diff
erent graphic setting, with 2D and
3D each having colors for roads, bl ocks, seas, and lakes, whilst shadow
changes and shadows are displa yed 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 iono sphere or reflections from objects
around the GPS equipment, can infl uence the accuracy with which the
GPS device can calculate the user's position.
