Description and Operation

Description
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 and car information.

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 outside 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 :
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 Cubis call center.
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, the driver is automatically connected every time he/she gets in the car.
C. USB connectivity : Outside 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.
Tunnels
Basement parking structures
Underneath an overpass
Roads within forested areas
Areas near high rise buildings
Roads within canyons
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.

Guidance may be given to a position differing from the current position when turning at an intersection.
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)

Speaker Repair procedures

Inspection
1. Troubleshooting for Speaker
(1) Basic inspection of speaker

Inspect the sound from speaker after verifying that the speaker mounting screws is removed and the wiring connector is connected precisely to remove vibration transmitted from body trims and surrounding parts.

(2) Case Troubleshooting

No
Case
Inspection/Remedy
1
Trembling sound
1. Before replacing the speaker, inspect that the mounting screw is installed normally.
2. After re-installing the speaker, verify that no trembling sound is heard.
3. When hearing a trembling sound again, replace the speaker with new one.
2
Noise
1. Check if the wiring connector is connected normally. If not, reconnect the wiring connector.
2. In case of radio static, check if there is a noise from CD player.
3. When a noise is heard on turning radio and CD on, replace the speaker with new one.
  
In case there is only radio static, this causes from poor radio reception. Thus the speaker needs no repair and replacement.
3
Poor working
Inspection of the wiring connection between the battery and the speaker
1. Before replacing the speaker, inspect the wiring and connections in the speaker circuit.
2. Check the supplying power to the speaker and the resistance, and then inspect the sound quality.

3. If the speaker works poorly, replace it with new one.

  
During dealing of speaker
Dropping or rough handling of the speaker can cause damage.
Be careful not to cover water and oil over the speaker.
Caution during dealing of speaker because the material of diaphragm is paper which is easy to be torn by impact and external force.
When modifying audio system as customer pleases, this does electric damage to speaker.
And, in this case the speakers are not covered by the manufacturer's warranty.
