Online Road Information Saved in
Route Search
The recommended route between two points
is not always the same. Even when offline,
statistics on traffic information (prior traffic
data or traffic patterns) are gathered in the
main unit, and when data is available, a route
is searched for taking into account statistics
relating to the day, week, and time.
Additionally, real-time traffic information
(TMC) is also available, allowing you to avoid
traffic jams due to temporary road closures or
accidents. This has an impact on any function
for which data is available.
Smart route using traffic information in
saved statistics
When statistical information is included in
map data, the information can be taken into
account when searching for a route. This
function is normally useful for avoiding traffic
jams that usually occur on regular weekdays,
however errors may occur if a national
holiday and so on falls on a regular weekday.
In situations like that, you can turn off Smart
route from Traffic settings. (See page 147)
Real-time traffic information (TMC)
Unlike the statistical traffic information TMC
(Traffic Message Channel) offers real-time
traffic conditions. This can help you to avoid
traffic jams that could not be anticipated due
to road closures or accidents.
TMC uses a dedicated FM Radio Data
System (RDS) to broadcast real-time traffic
and weather reports.
The default settings use traffic information
when searching for a route.
The TMC receiver necessary to receive traffic
condition reports is built-in to some products,
but not for others. Contact your nearest
dealer.
If traffic data normally broadcast in your
region can be accessed, this received
information is automatically taken into
account. This does not need to be manually
set. FM radio stations broadcasting TMC
data are searched for automatically, and
decoded information is immediately used to
search for routes. If traffic information that
might affect the current route is received, a
warning is displayed indicating that the route
will be searched for again, and navigation
continues using a new optimal route taking
into account the latest traffic conditions.
By delaying the timing before applying a
route that has been searched again, the user
can check the route and fine-tune the details
creating the optimal search results. You can
set this from Traffic settings. (See page 147)
When traffic information is being received, a
special icon (
) is displayed on the map.
When there is no traffic information available
for the route, this icon indicates the status of
the traffic information receiver, and when
information is received, the type of upcoming
traffic information is displayed.
Road sections affected by traffic conditions
are displayed in a different colour on the map,
and a small icon representing the type of
traffic condition is displayed above the road.
