Troubleshooting
The current position as shown on the navigation may differ from 
the actual position under the following conditions.
 The following occurrences are not malfunctions:
 
•
When driving on Y-shaped roads 
with narrow angles the current 
position may be displayed in the 
opposite direction
 
•
Within city streets, the current posi-
tion may be displayed on the oppo-
site side or on an off-road position
 
•
When changing the zoom level 
from maximum to a different level, 
the current position may become 
displayed on a different road
 
•
If the vehicle is loaded onto a ferry 
or a car transport vehicle, the cur-
rent position may become stalled 
on the last position prior to loading
 
•
When driving on a spiral-shaped 
road
 
•
When driving in mountain regions 
with sharp turns or sudden brakes
 
•
When entering a road after passing 
an underground parking structure, 
building parking structure, or roads 
with many rotations
 
•
When driving in heavy traffic with 
frequent starts and stops 
•
When driving under slippery condi-
tions, such as heavy sand, snow, etc.
 
•
When driving on spiral-shaped roads
 
•
When the tires have recently been 
replaced (Especially upon use of 
spare or studless tires).
 
•
When using tires of improper size
 
•
When the tire pressure for the 4 tires 
are different
 
•
When the replacement tire is worn or 
used (Especially studless tires having 
passed a second season).
 
•
When driving near high-rise buildings
 
•
When a roof carrier has been installed
 
•
When a long distance route is calcu-
lated while driving on an expressway 
In such cases, continued driving will 
automatically enable the system 
to conduct map matching or use 
updated GPS information to provide 
the current position (In such cases, up 
to several minutes may be required)
Correct route guidance may not occur due to search conditions or 
driving position.
The following occurrences are not malfunctions:
 
•
Guidance to go straight may be 
given while driving on a straight 
road
 
•
Guidance may not be given even 
when having turned at an inter-
section
 
•
There are certain intersections in 
which guidance may not occur
 
•
A route guidance signaling for 
a u-turn may occur in some No 
u-turn intersections  
•
Route guidance signaling 
entrance into a No-entry zone 
may occur (No-entry zone, road 
under construction, etc.)
 
•
Guidance may be given to a posi-
tion that is not the actual destina-
tion if roads to reach the actual 
destination do not exist or are too 
narrow
 
•
Faulty voice guidance may be 
given if the vehicle breaks away 
from the designated route. (e.g. if 
a turn is made at an intersection 
while the navigation provided 
guidance to go straight.)
These situations may occur after conducting route calculation.
 The following occurrences are not malfunctions:
 
•
Guidance may be given to a 
position differing from the current 
position when turning at an inter-
section
 
•
When driving in high speeds, 
route recalculation may take a 
longer period of time
 
•
Route guidance signaling for a 
u-turn may occur in some No 
u-turn intersections 
•
Route guidance signaling entrance 
into No-entry zone may occur 
(No-entry zone, road under construc-
tion, etc.).
 
•
Guidance may be given to a position 
removed from the actual destination 
if roads to reach the actual destina-
tion do not exist or are too narrow
 
•
Faulty voice guidance may be given 
if the vehicle breaks away from the 
designated route (e.g. If a turn is 
made at an intersection while the 
navigation provided guidance to go 
straight.)
