AVN system
The AVN system has improved information search and easiness
of manipulation for the driver by simplifying the system operation
experience and unifying the display of the user information such as
multimedia, air-conditioning and car information.
The system is basically composed of a keyboard for the
operation of combined function, 8-inch LCD monitors with wide viewing
angle in front seats, a head unit with Bluetooth handsfree calling,
voice recognition and navigation, music amplifier for operation from the
backseats, and the media unit that connects with other outside devices.
| 1. |
Simplification of user interface: the multimedia,
air-conditioning and car information are displayed on the monitor and
operated from the front keyboard. |
| 2. |
Networked electronic parts: Efficient information transmission through CAN communications |
| 3. |
Up-to-date technologies integrated:
| A. |
Voice recognition: This function recognizes the user's voice
commands to manipulate the system. The user can issue voice commands to
operate AV system, Bluetooth phone and navigation and connect to Blue
link call center(USA only). |
| B. |
Bluetooth hands-free calling: This is compliant with the
international wireless communication standards and uses Bluetooth
technology adopted in most currently launched mobile phones. Once
connected, it is automatically linked to the driver’s cell phone
whenever the driver gets in the car. |
| C. |
USB connectivity: Portable music player devices such as USB
memory stick or Walkman can be connected and played with the car
speakers. |

Limitations Of The Navigation system
GPS Signal Reception State
As the GPS satellite frequency is received/transmitted in
straight lines, reception may not work if hiding devices are placed on
or near the GPS antenna or when traveling through the following
locations.
| • |
Basement parking structures |
| • |
Roads within forested areas |
| • |
Areas near high rise buildings |
Vehicle Position Display
| 1. |
If multipass errors occur due to reflections from buildings
or related causes, the current position mark on the navigation may
differ from the actual position of the vehicle. |
| 2. |
The position of the vehicle on the navigation may be
different from the actual position if the vehicle is under the occur,
driving for a short period of time will vehicle through map matching or
GPS information (several minutes may be necessary in certain cases).
| A. |
When driving on a Y-shaped road with a narrow angle, the current position may be displayed in the opposite direction. |
| B. |
If the vehicle is loaded onto a car transport vehicle, the
current position mark may be stalled on the last position prior to
loading. |
| C. |
When driving on a spiral-shaped road. |
| D. |
When driving in mountain regions with sharp turns or sudden brakes. |
| E. |
When entering a road after having been in an underground
parking structure, building parking structure, or turnable with many
rotations. |
| F. |
When the tires have recently been replaced (Especially upon use of spare or studless tires) |
| G. |
If the battery terminal is removed. |
| H. |
When driving in city streets, the current position may be displayed on the opposite side or on an off-road position. |
| I. |
When changing the zoom level from the maximum zoom in level
to a different zoom level, the current position mark may be displayed on
a different road. |
| J. |
When driving in heavy traffic with frequent go · stops in traffic or intersections. |
| K. |
When driving under slippery conditions, such as heavy sand, snow, etc. |
| L. |
When driving with the tire chain in place. |
| M. |
When using a tire with an incorrect size specification. |
| N. |
When the tire pressure for the 4 tires are different. |
| O. |
When the replacement tire is a worn or used tire (Especially studless tires having passed a 2nd seasons, etc.) |
| P. |
When driving near high-rise buildings |
| Q. |
If a roof carrier has been installed |
| R. |
When driving under high speeds or having calculated a long-distance route. |
|
Route Guidance
Suitable route guidance may not occur caused by search conditions or the driving position.
| • |
Guidance to go straight may be given while driving on a straight road. |
| • |
Guidance may not be given even when having turned at an intersection. |
| • |
There are certain intersections in which guidance may not occur. |
| • |
A route guidance signaling entrance into a no enter zone may occur (No enter zone, road under construction, etc.) |
| • |
Guidance may be given to a position removed from the actual
destination if roads to reach the actual destination do not exist or are
too narrow. |
| • |
Faulty voice guidance may be given if the vehicle breaks from
the designated route (ex : if a turn is made at an intersection while
the navigation provided guidance to go straight). |
| • |
Map Data may be missing or incorrect causing route guidance to not be given. |
Route Re-calculation
The following phenomena may occur after conducting route recalculation.
| • |
When turning at an intersection, the navigation system gives wrong information on the current position. |
| • |
Route recalculation may take a longer period of time when driving under high speeds. |
| • |
A route guidance signaling for a U-Turn in a No U-Turn location may occur. |
| • |
A route guidance signaling entrance into a no enter zone may occur (No enter zone, road under construction, etc). |
| • |
Guidance may be given to a position removed from the actual destination do not exist or are too narrow. |
| • |
Faulty voice guidance may be given if the vehicle breaks from
the designated route (ex : if a turn is made at an intersection while
the navigation provided guidance to go straight) |
