NAVIGATION SYSTEM SYSTEM DESCRIPTION


  1. NAVIGATION SYSTEM OUTLINE


    1. 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)

      B0026SIE21
      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 SD card.
      Map Matching The map data from the SD card 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 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.

      Tech Tips

      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. 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.

      B0025L4E01
      *1 Current longitude/latitude/altitude is determined using the signal arrival time from four satellites.
      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. 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 SD card and the vehicle position is set onto the most appropriate road.

      B0026AEE05
    5. Touch switch

      The display is a capacitive touch screen panel. A capacitive touch sensor is also used for the panel switch.

      Tech Tips

      The sensitivity of the panel switch can be adjusted.

  2. DISC PLAYER OUTLINE


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

      CAUTION:

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

      Note


      • Do not disassemble any part of the disc player.

      • Do not apply oil to the disc player.

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

      • Some CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) may deteriorate if they are left in the cabin for a long time.

      • Keep CD-Rs, CD-RWs, DVD-Rs (DVD-Recordable) and DVD-RWs (DVD-ReWritable) in an opaque case.

      • SECAM color television standard discs 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 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, disc 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 discs 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.

      • Use only 4.7 in. (12 cm) discs.

      • Do not use 3 in. (8 cm) CDs either with or without adaptors.

      Tech Tips


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

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

  5. RADIO DESCRIPTION


    1. Radio frequency band


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

        B0027IOE42
    2. Service area


      1. B0026E2C06
        *a FM (Stereo)
        *b FM (Monaural)
        *c AM

        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

      Tech Tips

      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. B0028VGC06
        *a Phasing
        *b Ionosphere

        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. B00250AC06
        *a Multipath

        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. B0027NXC05
        *a Fade Out

        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
      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
  6. RDS-TMC FUNCTION OUTLINE (w/ RDS-TMC Function)


    1. This system has a function which allows the reception of traffic information from Radio Data System Traffic Message Channel (RDS-TMC) stations based on FM-multiple broadcasting. It assists the driver to avoid areas with traffic congestion. It also helps to improve traffic flow and road safety. Traffic information can be viewed.

  7. TOYOTA LINK FUNCTION OUTLINE (w/ Toyota Link Function)


    1. Enables the usable content of a cellular phone to be displayed on and operated from the multi-display screen. As "Bluetooth" communication is used for the communication between a cellular phone and the navigation receiver assembly, before using the Toyota Link function on the navigation system, the cellular phone needs to be registered with the navigation system as a "Bluetooth" device. For details regarding Toyota Link, applications and compatible phones, refer to http://www.toyota.com.au/.

  8. DIGITAL AUDIO BROADCAST (DAB) FUNCTION OUTLINE (w/ DAB Function)


    1. Digital Audio Broadcast (DAB) is the standard for digital radio. Compared to conventional FM/AM broadcasting, DAB enables higher sound quality radio broadcasting with lower noise when reception conditions change. DAB has an FM-Link function that automatically and temporarily changes to the simultaneously broadcasted FM station when the DAB broadcasting reception level falls.

  9. USB AUDIO SYSTEM FUNCTION OUTLINE


    1. The No. 1 stereo jack adapter assembly is equipped with a USB terminal. Connecting a USB device or "iPod" to the No. 1 stereo jack adapter assembly allows music files to be played.
