Problems with Route
Guidance
Inappropriate route guidance can
occur under one or more of the
following conditions:
The turn was not made on the
road indicated.
Route guidance might not be
available when using automatic
rerouting for the next right or
left turn.
The route might not be changed
when using automatic rerouting.
There is no route guidance when
turning at an intersection.
Plural names of places might be
announced occasionally.
It could take a long time to
operate automatic rerouting
during high-speed driving.
Automatic rerouting might
display a route returning to the
set waypoint if heading for a
destination without passing
through a set waypoint.
The route prohibits the entry of a
vehicle due to a regulation by
time or season or any other
regulation which may be given.
Some routes might not be
searched.
The route to the destination
might not be shown if there are
new roads, if roads have
recently changed, or if certain
roads are not listed in the map
data. See Maps 0 25.
To recalibrate the vehicle's position
on the map, park with the vehicle
running for two to five minutes, until
the vehicle position updates. Make
sure the vehicle is parked in a
location that is safe and has a clear
view of the sky and away from large
obstructions.

air. Map updates occur within a
161 km (100 mi) radius around the
home address on file. This
boundary will adjust over time
based on driving patterns. The
vehicle uses a Cloud-connected
service to receive the date and
downloads it to the system s
onboard SD card, if equipped.
A data plan or compatible mobile
device hotspot is required. The SD
