Description and operation
AVN system
The
AVN system simplifies system manipulation and by unifying the vehicle
information and user information displays, improves information search
and operation experience.
The
system is basically composed of a keyboard for the operation of
combined function, LCD monitor, a head unit with Bluetooth handsfree
calling, voice recognition and navigation, music amplifier and the media
unit that connects with other external devices.
| 1. | Simplification of user interface : the multimedia and car information are displayed on the monitor. |
| 2. | Networked electronic parts : Efficient information transmission through CAN communications. |
| 3. | Up-to-date technologies integrated : | •
| 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. |
| •
| 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, the driver is
automatically connected every time he/she gets in the car. |
| •
| USB
connectivity : External music player devices such as USB memory stick
or MP3 can be connected and played by 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 an object is placed on or near the GPS antenna
or when travelling in the following environment:
| •
| 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 in the following location or driving
condition. In this case, drive for a short period of time to
automatically correct vehicle location according to map matching or GPS
information. (It may take several minutes in certain cases.) | •
| When driving on a sharp Y-shaped road, the current position may be displayed in the opposite direction. |
| •
| If
the vehicle is loaded onto a car transport vehicle, the current
position mark may be stalled on the last position prior to loading. |
| •
| When driving on a spiral-shaped road. |
| •
| When driving in mountainous regions with sharp turns or sudden brakes. |
| •
| When
entering a road after exiting from an underground parking structure,
building parking structure, or turntable with multiple rotations. |
| •
| When the tires have recently been replaced (Especially upon use of spare or studless tires) |
| •
| If the battery terminal is removed. |
| •
| When driving in city streets, the current position may be displayed on the opposite side or on an off-road position. |
| •
| 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. |
| •
| When driving in heavy traffic with frequent stops or intersections. |
| •
| When driving under slippery conditions, such as heavy sand, snow, etc. |
| •
| When driving with tire chains installed. |
| •
| When using a tire with an incorrect size specification. |
| •
| When the tire pressures of all 4 tires are different from each other. |
| •
| When the replacement tire is a worn or used tire (especially studless tire that has passed 2nd season, etc.). |
| •
| When driving near high-rise buildings |
| •
| If a roof carrier has been installed |
| •
| When driving in high speeds or after having calculated a long distance route. |
|
Route Guidance
Suitable route guidance may not occur due to search conditions or driving position.
| •
| Guidance to go straight may be given while driving on a straight road. |
| •
| Guidance may not be given after turning at an intersection. |
| •
| Proper guidance may not be given at certain intersections. |
| •
| A route guidance signaling entrance into a no entry zone may occur (No entry zone, road under construction, etc.). |
| •
| Guidance
may be given to a location near the actual destination if roads to the
actual destination do not exist or are too narrow. |
| •
| Wrong
voice guidance may be given if the vehicle deviates from the designated
route (e.g. If it turned at an intersection wherein the navigation
guided to go straight.). |
| •
| The route guidance may not be provided in case of missing or incorrect map data. |
Route Re-calculation
The following phenomena may occur after conducting route recalculation.
| •
| Guidance may be given to a different position from the current position if the vehicle was turning at an intersection. |
| •
| Route recalculation may take longer when driving under high speeds. |
| •
| A route guidance signaling for a U-Turn in a No U-Turn zone may occur. |
| •
| In some cases, a route guidance may signal the driver to enter a no entry zone (No entry zone, road under construction, etc.). |
| •
| Guidance
may be given to a location near the actual destination if roads to the
actual destination do not exist or are too narrow. |
| •
| Wrong
voice guidance may be given if the vehicle deviates from the designated
route (e.g. If it turns at an intersection wherein the navigation
guided to go straight.). |
Repair procedures
Inspection
Check
if the auto light control operates like a timing chart shown below.
Tail lamp output and head lamp (Low) output is controlled based on the
auto light sensor's input (illumination intensity) when the Auto Light
Switch in Multi-Function Switch is turned ON, and the vehicle is in IGN1
or IGN2 ON Mode...
