  1. NAVIGATION RECEIVER ASSEMBLY OUTLINE


    1. A017B74E01

      Conventionally, 2 separate devices, a "radio and display" and a "navigation ECU" are used. This model has adopted a type that combines these devices into a single unit. The hard disk drive which contains map and other data is built into the navigation ECU.

      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 navigation 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 navigation 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 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 navigation 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.
      Tip:

      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.

    2. Autonomous navigation

      This method determines the relative vehicle position based on the driving track determined by the gyro located in the navigation receiver assembly and the vehicle speed signal.


      1. Gyro sensor

        Used to calculate the direction by detecting angular velocity. It is located in the navigation receiver assembly.

      2. Vehicle speed signal

        Used to calculate the vehicle driving distance.

    3. A017G6RE07

      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.
    4. A017DV4E40

      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.

    5. A017BGJE05

      Touch switch

      Touch switches are touch-sensitive (interactive) switches operated by touching the screen. When a switch is pressed, the outer glass bends in to contact the inner glass at the pressed position. By doing this, the voltage ratio is measured and the pressed position is detected.

  3. CD (COMPACT DISC) PLAYER OUTLINE


    1. A compact disc player uses a laser pickup to read digital signals recorded on a compact disc (CD). By converting the digital signals to analog, it can play music and audio.

      CAUTION:

      Do not look directly at the laser pickup because the CD player uses an invisible laser beam. Be sure to operate the player only as instructed.

      Note:

      • Do not disassemble any part of the CD player.

      • Do not apply oil to the CD player.

      • Do not insert anything but a CD into the CD player.

    2. Usable discs


      1. A017FT3

        This player can play only audio CDs, CD-Rs (CD-Recordable) and CD-RWs (CD-ReWritable) that have any of the following marks:

    3. Precautions for use of discs

      Note:

      • Copy-protected CDs cannot be played.

      • CD-Rs and CD-RWs may not be played depending on the recording conditions or characteristics of the discs, or due to damage, dirt or deterioration caused by leaving the discs in the cabin for a long time.

      • Unfinalized CD-Rs and CD-RWs cannot be played.

      • DualDiscs that mate DVD recorded material on one side with CD digital audio material on the other cannot be played.

      • Keep the discs away from dirt. Be careful not to damage the discs or leave your fingerprints on them.

      • Hold discs by the outer edge and center hole with the label side up.

      • Leaving the disc exposed halfway out of the slot for a long time after pressing the disc eject button may cause deformation of the disc, making the disc unusable.

      • If discs have adhesive tape, stickers, CD labels or any traces of such labels attached, the discs may not be ejected or player malfunctions may result.

      • Keep the discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of the disc, making the disc unusable.)

      • Do not use odd-shaped CDs because these may cause player malfunctions.

      • Do not use discs whose recording portion is transparent or translucent because they may not be inserted, ejected or played normally.

      Tip:

      • When it is cold or it is raining, if the windows mist up, mist and condensation may form in the player. In such cases, the CD may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.

      • The CD may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.

    4. A017BWX

      Cleaning

      Note:

      Do not use a lens cleaner because it may cause a malfunction in the pickup portion of the player.


      1. If dirt is on the disc surface, wipe it clean with a soft dry cloth such as an eyeglass cleaner for plastic lenses from the inside to the outside in a radial direction.

        Note:

        • Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface.

        • Use of solvents such as record spray, antistatic agents, alcohol, benzine, thinners or a chemical cloth may cause damage to the disc, making the disc unusable.

  7. RADIO DESCRIPTION


    1. Radio frequency band


      1. A017F9PE01

        Radio broadcasts use the radio frequency bands shown in the table below.

    2. A017DDFE01

      Service area


      1. 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.

    3. Radio reception problems

      Tip:

      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.


      1. A017E6CE02

        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.

      2. A017BULE02

        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.

      3. A017G37E02

        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.

    4. 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
      AM Noise occurs when listening to an intermittent broadcast An identical program transmitted from multiple towers can cause noise where the signals overlap
      AM Noise occurs only at night Signal phasing
      FM Noise occurs while driving in a specified area Multipath noise resulting from a change in FM frequency
