Route Setting Information

Route search specifications

Your navigation system sets a route to your desti-
nation by applying certain built-in rules to the
map data. This section provides some useful
information about how a route is set.
• When a route is calculated, the route and
voice guidance for the route is automati-
cally set. Also, for day or time traffic regu-
lations, only information about traffic
regulations at the time when the route was
calculated is shown. One-way streets and
street closures may not be taken into con-
sideration. For example, if a street is open
during the morning only, but you arrive
later, it would be against the traffic regula-
tions so you cannot drive along the set
route. When driving, please follow the
actual traffic signs. Also, the system may
not know some traffic regulations.
About singular route calculation
When the calculation of only one route is set, you
can search a route option by combining the fol-
lowing conditions.
How to set the calculation conditions
Page 48
For example, when "Fast" and "Avoid Motor-
way" ("On") are combined, a route that avoids
motorways and has the shortest travel time will
be calculated and displayed on the screen.
Condition 1: whether to put priority on dis-
tance or time
Short:
Calculate a route with the shortest distance to
your destination as a priority.
Fast:
Calculate a route with the shortest travel time to
your destination as a priority.
Condition 2: whether to use motorway or not
Avoid Motorway:
Calculate a route that avoids motorways. (A route
using the motorway may be set if your destination
is far away.)
• The system assumes that the driver deviated
either intentionally or inadvertently from the
route and searches for another route (intelli-
gent rerouting). Depending on the situation,
the system may search for a new route that
does not return to the original one.
• The calculated route is one example of the
route to your destination decided by the navi-
gation system while taking the type of streets
or traffic regulations into account. It is not nec-
essarily an optimum route. (In some cases, you
may not be able to set the streets you want to
pass. If you want to pass a certain street, set
the way point on that street.)
• The route set by your navigation system is
based on the assumption that the driver does
not know the area. Thus, streets known to local
drivers, such as small streets or special roads,
may not be used for the set route.
• Some route options may become the same
route. If way points are set, only one route is
calculated.
• Route setting is limited to the range of the disc
in use.
• The destination is too far, there may be
instances where the route cannot be set. (If
you want to set a long-distance route going
across several areas, set way points along the
way.)
• During voice guidance, turns and junctions
from the motorway are announced. However,
some junctions, turns, and other guide points
may not be announced if they are passed in
rapid succession.
• It is possible that guidance may direct you off a
motorway and then back on again.
• In some cases, the set route may require you to
travel in the opposite direction of your current
heading. In such cases, you are instructed to
turn around; please do so safely and in accord-
ance with local traffic rules.
• In some cases, guidance may direct you past
your destination and then indicate a U-turn to
get back to it.
• In some cases, a route may begin on the oppo-
site side of a railway or river from your actual
current location. If this happens, drive towards
