1. NAVIGATION SYSTEM OUTLINE Vehicle position tracking methods It is essential that the navigation system correctly tracks the current vehicle position and displays it on the map. There are 2 methods to track the current vehicle position: autonomous (dead reckoning) and GPS* (satellite) navigation. Both navigation methods are used in conjunction with each other. *: GPS (Global Positioning System) Operation Description Vehicle Position Calculation The multi-media module receiver assembly calculates the current vehicle position (direction and current position) using the direction deviation signal from the gyro sensor and driving distance signal from the vehicle speed sensor and creates the driving route. Map Display Processing The multi-media module receiver assembly processes the vehicle position data, vehicle driving track and map data from the hard disk drive. Map Matching The map data from the hard disk drive is compared to the vehicle position and driving track data. Then, the vehicle position is matched with the nearest road. GPS Correction The vehicle position is matched to the position measured by the GPS. Then, the GPS measurement position data is compared with the vehicle position and driving track data. If the position is very different, the GPS measurement position is used. Distance Correction The vehicle speed signal includes the error caused by tire wear and slippage between the tires and road surface. Distance correction is performed to account for this. The multi-media module receiver assembly automatically offsets the signal to make up for the difference between it and the distance data of the map. The offset is automatically updated. HINT: The combination of autonomous and GPS navigation makes it possible to display the vehicle position even when the vehicle is in places where GPS signals cannot be received. When only autonomous navigation is used, however, the mapping accuracy may slightly decrease. Autonomous navigation This method determines the relative vehicle position based on the driving track determined by the gyro located in the multi-media module receiver assembly and the vehicle speed signal. Gyro sensor Used to calculate the direction by detecting angular velocity. It is located in the multi-media module receiver assembly. Vehicle speed signal Used to calculate the vehicle driving distance. GPS * navigation (Satellite navigation) This method detects the absolute vehicle position using radio waves from GPS satellites. *: GPS satellites were launched by the U.S. Department of Defense for military purposes. Number of Satellites Measurement Description 2 or less Measurement is impossible Vehicle position cannot be obtained because the number of satellites is not enough. 3 2-dimensional measurement is possible Vehicle position is obtained based on the current longitude and latitude. (This is less precise than 3-dimensional measurement.) 4 3-dimensional measurement is possible Vehicle position is obtained based on the current longitude, latitude and altitude. Map matching The current driving route is calculated by autonomous navigation (according to the gyro sensor and vehicle speed signal) and GPS navigation. This information is then compared with possible road shapes from the map data in the hard disk drive and the vehicle position is set onto the most appropriate road.
2. REMOTE TOUCH OUTLINE HINT: The navigation system is remotely controlled using the remote touch switch knob and switches. The remote touch is equipped with a feedback force function. When the remote touch switch knob is operated, the built-in 2-axis motors are controlled. The motors are used to provide feedback force for the knob according to the pointer operation displayed on the multi-display assembly. The feedback force of the remote touch allows the users to select icons easily when operating the navigation system. Remote Touch Switch Knob Operation TEXT IN ILLUSTRATION *a Example *b Longitudinal Axis *c Lateral Axis *d Switch Knob Movement of the pointer on the multi-display assembly screen is synchronized with knob operation. HINT: During remote touch switch knob operation, the distance that the knob moves is sent to the multi-media module receiver assembly as operational coordinates. The range of operational coordinates for the lateral and longitudinal axes is between 0 and 255. The multi-display assembly also has operational coordinates that range from 0 to 255 for the lateral and longitudinal axes. The multi-media module receiver assembly displays the pointer according to the operational coordinates from the knob. Remote Touch Switch Knob Feedback Force TEXT IN ILLUSTRATION *a Example *b Display *c Feedback Force Image Screen *d Screen Image *e Feedback Force Image *f Pointer *g Movement Direction *h Feedback Force (When Providing Resistance) The remote touch has 2 built-in motors. These motors control both lateral and longitudinal axes and generate feedback force according to remote touch switch knob operation. HINT: There are 3 types of feedback force image areas (icons, frames and others) provided on the multi-display assembly screen. The feedback force changes depending on the area. The multi-media module receiver assembly sends a feedback force request signal to the remote touch according to the pointer location displayed on the multi-display assembly. When the remote touch receives the feedback force request signal, the remote touch controls the motors and generates 3 types of feedback force according to the operation direction of the remote touch switch knob. The strength of feedback force generated by the remote touch can be adjusted. Refer to the owner's manual for further information. Icon Area TEXT IN ILLUSTRATION *a Example *b Display *c Generated Feedback Force *d Switch Knob Operation *e Icon *f Force to Pull Pointer to Center of Icon *g Center of Icon *h Feedback Force HINT: When the pointer comes close to an icon area, force will be provided to pull the pointer toward the center of the icon area. Stronger force is provided while driving than while parked. Frame Area TEXT IN ILLUSTRATION *a Example *b Frame Area *c Feedback Force - - HINT: Frame areas are provided for the edges of all display screens. When the pointer comes close to the edge of the screen, force will be provided to move the pointer away from the edge of the screen. Other Area TEXT IN ILLUSTRATION *a Example *b Generated Feedback Force *c Switch Knob Operation (User Input) *d Fast Knob Operation (Strong Feedback) *e Slow Knob Operation (Weaker Feedback) *f Feedback Force HINT: When the pointer is in an area other than one of those specified, resistance will be provided that is proportional to the remote touch switch knob operation speed. Stronger resistance is provided on the map screen than on other screens.

7. RADIO DESCRIPTION Radio frequency band Radio broadcasts use the radio frequency bands shown in the table below. Service area The service areas of AM and FM broadcasts are vastly different. Sometimes an AM broadcast can be received very clearly but an FM stereo broadcast cannot. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise. TEXT IN ILLUSTRATION *a FM (Stereo) *b FM (Monaural) *c AM Radio reception problems HINT: In addition to static, other problems such as "phasing", "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself. Phasing AM broadcasts are susceptible to electrical interference and another kind of interference called phasing. Occurring only at night, phasing is the interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off the ionosphere and the other signal is received directly from the transmitter. TEXT IN ILLUSTRATION *a Phasing *b Ionosphere Multipath Multipath is a type of interference created when a vehicle receives 2 radio wave signals from the same transmitter. One signal is reflected off buildings or mountains and the other signal is received directly from the transmitter. TEXT IN ILLUSTRATION *a Multipath Fade out Fade out is caused by objects (buildings, mountains and other such large obstacles) that deflect away part of a signal, resulting in a weaker signal when the object is between the transmitter and vehicle. High frequency radio waves, such as FM broadcasts, are easily deflected by obstructions. Low frequency radio waves, such as AM broadcasts, are less likely to deflect. TEXT IN ILLUSTRATION *a Fade Out Noise problem Technicians must have a clear understanding about each customer's noise complaint. Use the following table to diagnose noise problems. Radio Frequency Noise Occurrence Condition Presumable Cause AM Noise occurs in a specific area Foreign noise Noise occurs when listening to an intermittent broadcast An identical program transmitted from multiple towers can cause noise where the signals overlap Noise occurs only at night Signal phasing FM Noise occurs while driving in a specified area Multipath resulting from a change in FM frequency
