Description and Operation

Description

AVN System: The AVN system improves information search and ease of operation for the driver by simplifying system operation and unifying the display of user information, such as multimedia information and vehicle information. The system mainly consists of a combination keypad, LCD monitor, Bluetooth hands-free head unit with voice recognition and navigation, music amplifier, and multimedia unit that connects to other external devices.

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, and connect to the Cubis call center.
   • 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 connects automatically each time they enter 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.

Navigation System Limitations / GPS Signal Reception Condition: Because GPS satellite signals are received/transmitted in straight lines, reception may not work if masking objects are located on or near the GPS antenna, or when traveling in 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 display may differ from the actual position if the vehicle is driven for a short period while being towed or transported; the vehicle position will be corrected through map matching or GPS information (in some cases, this may take several minutes).

   • 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 steep curves or sudden braking.
   • When exiting onto a road after being in an underground parking structure, a building parking structure, or a turn with many rotations.
   • When 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 the scale level is changed from the maximum scale level to another scale level, the current position mark 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, 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 conditions or driving position.

• 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 set route (example: a turn is made at an intersection while the navigation system instructed 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.

• Guidance may be given to a position different from the current position when turning at an intersection.
• Route recalculation may take longer when driving at high speeds.
• Route guidance may indicate a U-turn at a location where a U-turn is 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 set route (example: a turn is made at an intersection while the navigation system instructed to go straight).
