Navigation
• (Vehicle):Sets various factors to take in to account when performing a
search, such as fuel consumption, vehicle model, fuel costs, and
maximum speeds on normal roads and expressways.
• (Navigation Mode): You can change between On-road and Off-road.
Set to On-road to perform normal navigation, or set to Off-road
to navigate using the straightest possible route to the
destination.
• (Route Planning Method): By changing the route search method, you can search for the
optimum route for a variety of si tuations and types of vehicle.
See the following items for more details.
• (Highways): Select whether or not to use the expressway when creating the
route.
• (Period Charge): Select whether or not to use toll roads (Period Charge) when
creating the route.
• (Per-use Toll): Select whether or not to use to ll roads (Per-use Toll) when
creating the route. • (Ferries):
Select whether or not to use ferries when creating the route.
(However, ferries might not always be selected for the route.)
However, information on temporary service ferries may not be
displayed on the map. There may be a fee for using the ferry.
•: Select whether or not to use Carpool/HOV lanes when creating
the route.
• (Unpaved Roads): Select whether or not to use unpaved roads when creating the
route.
• (Calculate Green Alternative): Select whether or not to consi der energy efficiency when
creating the route.
3Touch to set the changes. The route is searched
again, and the new recommended route is indicated by
an orange line.

Voice Control Navigation
By using the voice control system (voice input microphone
and button), you can set the destination by giving voice
commands. This enables you to use functions that are usually
inoperable while driving.
1By using the voice recognition button you can use voice
commands to operate the navigation. (See Page 288.)
2When using voice commands to operate the navigation,
a command list is displayed.
3Voice a command after the “beep”. From then on, you
can give voice commands that are displayed on the
command list to set the destination in the same manner.
• Voice control navigation can be interrupted by touching the
microphone icon on the screen. When the icon is touched, the
screen background color changes (green blue). To resume
navigation voice control, touc h the microphone icon again.
The differences in background colors are explained below.
- Command standby screen (green): This is the voice control command standby screen. When this
screen is displayed, you ca n speak a command to perform
navigation control. You can also perform control by directly
touching the commands that ar e displayed on the screen.
- Manual mode screen (blue): This screen appears when voice control is interrupted. You can
perform control by directly touching the commands that are
displayed on the screen.
- Talkback screen (yellow): This screen appears while the talkback voice is being played
when a command is recognized.
- Command recognition failed screen (red): This screen appears when command recognition failed.

Reference Data
• (Day Map Color):
Select the screen color used in daytime mode.
• (Night Map Color):
Select the screen color used in nighttime mode. •
(Track Logs):
Turns the path log save function on or off (saves in positional order
for each trip).
• (Place Markers):
Select a spot displayed on th e map during navigation. We
recommend reducing the number of spots displayed as much as
possible as the map is difficult to see if there are too many spots.
Because of this, the software is designed to allow multiple spot
displays. Follow the steps below.
- Touch the check box to show or hide the spot category.
- Touch the spot category name to open a sub-category.
- Touch (More) to save the currentl y displayed spot position, or read
spot displays saved previously. You can also restore the default display
settings.

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 an d menu screens differs for daytime
and nighttime. Each design has a different graphic setting, with 2D and
3D each having colors for roads, bl ocks, seas, and lakes, whilst shadow
changes and shadows are displayed differently in 3D mode.
Daytime screen and nighttime scr een designs for the map and menu
are selected one at a time. The desi gn 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.
Maps
Although this software uses digita l 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 differ ences in altitude for mountains,
valleys, highland roads and so on, an d display areas of cities using 3D
landmarks and 3D images of buildings.
The digital map can be used intera ctively. You can zoom in and out
(enlarge/reduce), tilt up and down, an d rotate left and right. By using
navigation that supports GPS, you ca n easily plan your route with the
digital maps.
North Up Map Direction
North Up mode rotates the map so th at 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”.
