Description and Operation

Description

AVN system

The AVN system simplifies system operation, integrates vehicle information, and displays user information, improving information retrieval and user experience.

The system mainly consists of a combination function control keypad, LCD monitor, Bluetooth hands-free head unit, voice recognition and navigation, audio amplifier, and media unit that connects to other external devices.

System Features

1. 1

   Simplified User Interface: Multimedia and vehicle information are displayed on the monitor.

2. 2

   Networked Electronic Components: Efficient information transmission via CAN communication.

3. 3

   Integrated Advanced Technologies:

   • Voice recognition: This function recognizes the user's voice commands to control the system. The user can give voice commands to control the AV system, Bluetooth phone, and navigation.

   • Bluetooth hands-free: This complies with international wireless communication standards and uses Bluetooth technology adopted in most mobile phones currently on the market. Once paired, the driver's phone connects automatically each time the driver gets into the vehicle.

   • USB connection: External music players, such as a USB memory card or MP3 player, can be connected and played through the vehicle speakers.

   • Mirror link: Allows various smartphone functions to be combined with the AVN system and displayed on the monitor (route guidance, phone, music, etc.).

Navigation System Limitations

GPS Signal Reception Condition

Because GPS satellite signals are received/transmitted in straight lines, reception may not work if obstructing objects are placed on or near the GPS antenna, or when driving through the following locations.

• Tunnels

• Underground parking structures

• Under elevated roads

• Roads through forested areas

• Areas near high-rise buildings

• Canyon roads

Vehicle Position Display

1. 1

   If multipath errors occur due to reflections from buildings or related causes, the current position mark on the navigation screen may differ from the actual vehicle position.

2. 2

   The vehicle position on the navigation system may differ from the actual position if the vehicle is subjected to, or driven for a short time through, map matching or GPS information correction (may take several minutes in some cases).

   • When driving on a Y-shaped narrow-angle road, the current position may be displayed in the opposite direction.

   • If the vehicle is loaded onto a car carrier, the current position mark may stop at the last position before loading.

   • When driving on a spiral road.

   • When driving in mountainous areas with sharp curves or sudden braking.

   • When exiting after being in an underground parking structure, a building parking structure, or a turn structure with many consecutive turns.

   • When the tires have been recently replaced (especially after using temporary spare or non-studded tires).

   • If the battery terminal has been disconnected.

   • When driving on city streets, the current position may be displayed on the opposite side of the road or in an off-road position.

   • When changing the scale from the maximum scale to another scale, the current position marker may be displayed on a different road.

   • When driving in heavy traffic with frequent stops or at intersections.

   • When driving on slippery roads, such as deep sand or snow, etc.

   • When driving with snow chains installed.

   • When using tires of an incorrect size.

   • When the tire pressure differs between the four tires.

   • When replacing a worn or used tire (especially a non-studded tire that has been in use for a second season, etc.)

   • When driving near high-rise buildings.

   • If a roof rack is installed.

   • When driving at high speeds or when calculating a long-distance route.

Route Guidance

Proper route guidance may not be performed due to search or driving position conditions.

• On a straight road, a straight-ahead instruction may be given.

• Guidance may not be given even when turning at an intersection.

• There are certain intersections where guidance may not be provided.

• Route guidance may indicate entry into a restricted area (No Entry, road under construction, etc.).

• Guidance may be provided to a location away from the actual destination if roads leading to the actual destination do not exist or are too narrow.

• Incorrect voice guidance may be given if the vehicle leaves the designated route (example: a turn is made at an intersection while the navigation guidance says to go straight).

• Map data may be missing or incorrect, which may make route guidance impossible for the given destination.

Route Recalculation

The following phenomena may occur after route recalculation.

• When turning at an intersection, the navigation system may provide incorrect information about the current position.

• Route recalculation may take longer when driving at high speeds.

• A route guidance signal to make a U-turn may appear at a location where U-turns are prohibited.

• Route guidance may indicate entry into a restricted area (No Entry, road under construction, etc.).

• Guidance may be provided to a location away from the actual destination if roads leading to the actual destination do not exist or are too narrow.

• Incorrect voice guidance may be given if the vehicle leaves the designated route (example: a turn is made at an intersection while the navigation guidance says to go straight).
