Route setting information
1NTSDÐRD@QBGÐRODBHÆB@SHNMR
Your navigation system sets a route to your destination by apply-
ing certain built-in rules to the map data. This section provides
some useful information about how a route is set.
CAUTION
When a route is calculated, the route and voice guidance
for the route are automatically set. Also, for day or time
traffic regulations, only information about traffic regulations
applicable at the time when the route was calculated is
considered. One-way streets and street closures may not
be taken into consideration. For example, if a street is open
during the morning only, but you arrive later, it would be
against the traffic regulations 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.
The calculated route is one example of the route to your
destination decided by the navigation system while taking
the type of streets or traffic regulations into account. It is not
necessarily an optimum route. (In some cases, you may not
be able to set the streets you want to take. If you need to take
a certain street, set a waypoint on that street.)
If 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 waypoints along the way.)
During voice guidance, turns and intersections from the
motorway are announced. However, if you pass intersec-
tions, turns, and other guidance points in rapid succession,
some may delay or not be announced.
It is possible that guidance may direct you off a motorway
and then back on again.
In some cases, the route may require you to travel in the
opposite direction to your current heading. In such cases,
you are instructed to turn around, so please turn around
safely by following the actual traffic rules.
In some cases, a route may begin on the opposite side of
a railway or river from your actual current location. If this
happens, drive towards your destination for a while, and try
route calculation again.
When there is a traffic jam ahead, a detour route may not
be suggested if driving through the traffic jam would still be
better than taking the detour.
There may be instances when the starting point, the way-
point and the destination point are not on the highlighted
route.
The number of roundabout exits displayed on the screen
may differ from the actual number of roads.
Route highlighting
Once set, the route is highlighted in bright colour on the
map.
The immediate vicinity of your starting point and destination
may not be highlighted, and neither will areas with particu-
larly complex road layouts. Consequently, the route may
appear to be cut off on the display, but voice guidance will
continue.
Auto reroute function
If you deviate from the set route, the system will re-calculate
the route from that point so that you remain on track to the
destination.
This function may not work under certain conditions.
