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.
• Upgrade DVD Map Discs are available for
purchase from your local Pioneer dealer
that includes the most current map and
point of interest information. Contact your
local Pioneer dealer for details.
About the route condition
When the calculation of only one route is set, you
can search a route option by combining the fol-
lowing conditions.

For example, when “Fast” and “Avoid Freeway”
(“On”) are combined, the route, which avoids
freeway, and has the shortest travel time, will be
calculated and displayed on the screen.
Condition 1 :whether to put priority on the
distance, 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 freeway or not
Avoid Freeway :
Calculate a route that avoids freeway. (A route
using the freeway may be set if your destination
is far away.)
• The system assumes the driver deviated either
intentionally or inadvertently from the route
and searches for another route (intelligent
rerouting). Depending on the situation, the
system may search 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 whilst 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, the 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 visiting 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 intersections
from the freeway are announced. However, if
you pass intersections, turns, and other guide
points in rapid succession, some may not be
announced.
• It is possible that guidance may direct you off a
freeway and then back on again.
• In some cases, the set 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.
