ROUTE CALCULATION AND VISUAL GUIDANCE
SymptomPossible cause Possible solution
Waypoints are not included in the
auto reroute calculation. Waypoints that have been already passed are not included in
the auto reroute calculation. To go to that waypoint again, edit the route.
Route information is not dis-
played. Route calculation has not yet been performed.
Set the destination and perform route calcula-
tion.
The vehicle is not on the suggested route. Drive on the suggested route.
Route guidance is turned off. Turn on route guidance.
Route information is not provided for certain types of roads. This is not a malfunction.
The auto reroute calculation (or
detour calculation) suggests the
same route as the one previously
suggested. Route calculations took priority conditions into consideration,
but the same route was calculated.
This is not a malfunction.
A waypoint cannot be added. 14 waypoints are already set on the route, including ones that the vehicle has already passed. A maximum of 14 waypoints can be set on the
route. To go to 15 or more waypoints, perform
route calculations multiple times as necessary.
The suggested route is not dis-
played. Roads near the destination cannot be calculated.
Reset the destination to a main or ordinary road,
and recalculate the route.
The starting point and destination are too close. Set a more distant destination.
The starting point and destination are too far away. Divide the trip by selecting one or two inter- mediate destinations, and perform route calcu-
lations multiple times.
There are time restricted roads (by the day of the week, by
time) near the current vehicle location or destination. Select [Ignore Restrictions] in the [Time Re-
stricted Roads] setting.
“Route Preference” (page 6-34)
A part of the route is not dis-
played. The suggested route includes narrow streets. This is not a malfunction.

SymptomPossible cause Possible solution
The part of the route that the
vehicle has already passed is de-
leted. A route is managed by sections between waypoints. If the
vehicle passed the first waypoint, the section between the
starting point and the waypoint is deleted (it may not be
deleted depending on the area). This is not a malfunction.
An indirect route is suggested. If there are restrictions (such as one-way streets) on roads close to the starting point or destination, the system may
suggest an indirect route. Adjust the location of the starting point or
destination.
The system may suggest an indirect route because route
calculation does not take into consideration some areas such
as narrow streets. Reset the destination to a main or ordinary road,
and recalculate the route.
The landmark information does
not correspond to the actual in-
formation. This may be caused by insufficient or incorrect map data. Updated information will be included in the next
version of the map data.
“How to update map data” (page 6-62)
The suggested route does not
exactly connect to the starting
point, waypoints or destination. There is no data for route calculation closer to these locations. Set the starting point, waypoints and destination
on a main road, and perform route calculation.

VOICE GUIDANCE
SymptomPossible cause Possible solution
Voice guidance is not available. The vehicle has deviated from the suggested route. Go back to the suggested route or request
route calculation again.
Voice guidance is turned off. Turn on voice guidance.
Route guidance is turned off. Turn on route guidance.
The guidance content does not cor-
respond to the actual road conditions. The content of voice guidance may vary, depending on the types
of intersections at which turns are made. Follow all traffic rules and regulations.

TRAFFIC INFORMATION
SymptomPossible cause Possible solution
Traffic information is not displayed. Traffic information is not turned on. Turn on the traffic information.
The vehicle is in an area where traffic information is
not available. Scroll to an area where traffic information is available.

display of icons is possible.
“Traffic information on map” (page 6-43)
With the automatic detour route
turned on, no detour route is set to
avoid congested areas. There is no faster route compared to the current
route, based on the road network and the traffic
information. The automatic detour search is not intended for
avoiding traffic jams. It searches for the fastest route
taking conditions such as traffic jams into considera-
tion. Follow the current route.
“Notes on SiriusXM TrafficTMinformation”
(page 6-41)
The route does not avoid a road
section with traffic information stat-
ing that it is closed due to road
construction. The navigation system is designed not to avoid this
event because the actual period of closure may differ
from the declared roadwork period.
Observe the actual road conditions and follow the
instructions on the road for a detour when necessary.
If the road is closed, use the detour function and set
the detour distance to avoid the road section that is
closed.

VOICE RECOGNITION
SymptomPossible cause Possible solution
The system does not operate or fails to interpret
the command correctly. The interior of the vehicle is too noisy. Close the windows or have the other occupants
be quiet.
The fan speed of the heater/air conditioner is
too fast. Decrease the fan speed of the heater/air
conditioner.
The noise generated by driving the vehicle is too
loud. Reduce the vehicle speed.
The voice command is spoken in a low voice. Speak the command in a louder voice.
The timing of speaking a command is too early. Speak the command after confirming the fol- lowing: a voice guidance is announced, a tone
sounds, and an icon on the screen changes from
gray to orange.
The command is spoken too slowly. Speak in a natural voice without pausing
between words.
The system prompts to repeat a command. Pronunciation is unclear. Speak clearly.
The command is spoken too late after the tone. Speak the command within 5 seconds after confirming the following: a voice guidance is
announced, a tone sounds, and an icon on the
screen changes from gray to orange.
An improper command is spoken. Speak the command or a number that is
displayed on the screen.
Speak a command that is shown in the command
list.

SymptomPossible cause Possible solution
The system does not correctly recognize a
number spoken. Too many numbers are spoken at once. Place a pause between the appropriate digits for
correct recognition by the system. When
speaking a telephone number, place a pause
between area codes, dial codes, etc.
USB memory device cannot be operated with
voice commands. Depending on the device, iPhone® or iPod® may
be recognized as a USB memory device.This is not a malfunction.
The USB/iPod® operation screen is grayed out. The audio device is not connected. Connect an audio device to the system.
An error message is displayed when trying to
select a track and operate USB/iPod®. The track information is being processed for
registration by the system.Song information will be loaded into the system
when a new audio device is registered for the
first time or when the song information in the
pre-registered device has been changed. Please
wait for the loading to complete which may take
a few minutes to up to an hour.
A number of songs exceeding the amount the
device can contain are stored in the connected
audio device. Decrease the number of songs stored in the
audio device.
No song is stored in the audio device. Store songs in the connected audio device.
Storing songs with information such as artist
name, album name, song name, playlist, etc., will
make voice recognition song search available.
The system does not correctly recognize a Point
of Interest (POI) name spoken. There are some rare cases where a POI search is
unavailable by speaking the facility name but the
location can be found on the map.This is not a malfunction. Consider using an
alternate search method, like street address.
Partial or alias name is spoken. For best results, speak the full name.
