Accessories and Optional Equipment: Description and Operation
System Overview
The DIS (Driver Information System) has been designed so that it can connect to external devices (USB and iPod) and support Bluetooth. The system also interfaces with various other vehicle systems to display their statuses on screen. In addition, the screen itself is a touch screen.

DIS (Driver Information System)
- With the increasing complexity of electronic system in modern vehicles, we deliver the necessary expertise in total system integration such as multi media, air conditioning, and drive information.
1. DIS Concept : Adapted the interface to center keyboard -> Possible to change 8 directions. (Jog dial type)
2. MOST & Optical Fiber Communication : Faster transmission of data, reduced wiring weight and cost due to communication standard.
** MOST : Media Orientated System Transport
3. Integrate a state of art Multi media : Navigation, Bluetooth hands free, USB & i-Pod connector.
Main Features
A. Navigation
Storage the map information in Head Unit (HDD:40GB) which is apply to an unified navigation with Global Positioning System. (N/America, China)
Head unit is a combined with navigation in order to reduce the cost and weight.
Detecting the data is more 10 times fast than previous DVD navigation.
B. Voice Recognition (Only North America)
SDS : Speech Dialogue System that will allow drivers to get voice navigation guidance without having to manually enter in any information or take driver's eyes off the road to read a monitor's screen, it is possible to listen to radio, make a call, order to navigation.
C. Bluetooth Hands-free
Equipped with Bluetooth Hands-Free capability allow you to use voice command or steering mounted controls to make and receive calls, keeping your hands on the wheel and your eyes on the road. After completing the initial set-up, you can then pair up 5 cell phones with the system for multiple drivers.
D. i-Pod & USB
i-Pod, mp3 and USB are popular, therefore, it is possible to operate these devices and play through each speaker in the car.
It is possible to play mp3 data with USB memory.
i-Pod is able to operate with control keyboard.
Navigation
Description
How Does The Navigation System Work?
The position and movements of the vehicle are recorded by the navigation system's sensors. The distance travelled is determined by the vehicle speedometer signal, rotary motion in bends is detected by a gyro sensor (inertial compass). The position is determined via the GPS (Global Positioning System) satellites. The position can be calculated within a range of approx. 10 m by comparing the sensor signals with the digital map on the navigation HDD.
The Digital Road Map
To be able to plan a route to a destination address, the navigation system not only requires the current position of the vehicle but also a digital road map containing the destination address itself and the roads leading to the destination address. This digital road map is on the memory which is located in navigation unit.
The road system is stored on the map data as a line model, i.e. even large junctions have only one focal point that is approached by all roads in point-to-point fashion. Thus the navigation system indicates the distance to the turn-off point as the distance to the centre of the junction. This is why the distances for motorway exits indicated on road signs may not agree with those of the navigation system. The road signs indicate the distance to the beginning of the exit.
Areas with limited road information
In some areas, not all of the information on a road is available on the map data. Thus, for example, turn-off prohibitions, information on the direction of travel in a one-way street or prohibited entry into a pedestrian zone may be missing. The navigation system will display a warning if you drive into such an area. Local traffic laws always take precedence over navigation system instructions. Always observe the road signs and motor vehicle traffic regulations.
Topicality of the map data
Roughly 10 - 15% of the road system characteristics change each year. Due to these constantly changing traffic conditions (construction of new roads, traffic calming, etc.) we cannot guarantee that the digital road map will be in 100 % agreement with existing traffic conditions. We recommend that you always use the most current version of the map data for navigation.
