Kia Niro: AVN System / 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.).
