NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM (w/ USB Audio System): SYSTEM DESCRIPTION

1. NAVIGATION RECEIVER ASSEMBLY OUTLINE

(a) Conventionally, 2 separate devices, a "radio and display" and a "navigation ECU" are used. This model combines these devices into a signal unit.

2. NAVIGATION SYSTEM OUTLINE

(a) Vehicle position tracking methods

(1) 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.

HINT
*: GPS (Global Positioning System)

HINT
The combination of autonomous and GPS navigation makes it possible to display the vehicle position even when the vehicle is in places where the GPS radio wave cannot be received. When only autonomous navigation is used, the mapping accuracy may slightly decline.

(b) Autonomous navigation

This method determines the relative vehicle position based on the running track determined by the gyro and vehicle speed sensors.

(1) Gyro sensor

Calculates the direction by detecting angular velocity. It is located in the navigation receiver assembly.

(2) Vehicle speed sensor

Used to calculate the vehicle running distance.

(c) GPS navigation (satellite navigation)

This method detects the absolute vehicle position using radio waves from a GPS satellite*.

HINT
*: GPS satellites were launched by the U.S. Department of Defense for military purposes.

(d) Map matching

The current driving route is calculated by autonomous navigation (according to the gyro sensor and vehicle speed sensor) and GPS navigation. This information is then compared with possible road shapes from the map data on the map disc and the vehicle position is set onto the most appropriate road.

3. TOUCH SCREEN OUTLINE

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

4. DVD (Digital Versatile Disc) PLAYER OUTLINE (for Navigation Map)

(a) The navigation receiver assembly uses a laser pickup to read the digital signals recorded on a DVD.

CAUTION:
Because the navigation system uses an invisible laser beam, do not look directly at the laser pickup. Be sure to only operate the navigation system as instructed.

NOTICE:
* Do not disassemble any part of the navigation receiver assembly.
* Do not apply oil to the navigation receiver assembly.
* Do not insert anything but a DVD into the navigation receiver assembly.
5. CD (Compact Disc) PLAYER OUTLINE

(a) 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 other content.

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.

NOTICE:
* 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.
(b) Usable discs

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

(c) Precautions for use of discs

NOTICE:
* 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.
* Dual Discs 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 recorded portion is transparent or translucent because they may be unable to be properly inserted, ejected or played.
HINT
* 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.
(d) Cleaning

NOTICE:
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.

NOTICE:
* Pressing on the disc by hand or rubbing the disc with a hard cloth may scratch the disc surface.
* The use of solvents, such as a record spray, antistatic agent, alcohol, benzine, and thinner, or a chemical cloth may cause damage to the disc, making the disc unusable.

8. RADIO DESCRIPTION

(a) Radio frequency band

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

(b) 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.

(c) 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.

(1) 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) 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) 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 much more difficult to deflect.

(d) Noise problem

Technicians must have a clear understanding about each customer noise complaint. Use the following table to diagnose noise problems.

HINT
If the noise does not match the examples above, refer to the descriptions about phasing and multipath.

9. RBDS FUNCTION OUTLINE (BROADCAST IN NORTH AMERICA ONLY)

The Radio Broadcast Data System (RBDS) is broadcast through conventional FM radio broadcasts. Information such as song names, traffic information, broadcast station names, etc. can be received.

10. SDARS SYSTEM FUNCTION OUTLINE (BROADCAST IN NORTH AMERICA ONLY)

Satellite Digital Audio Radio Service (SDARS) is a satellite digital radio broadcast provided by Sirius XM Radio Inc. The broadcast (pay-type) is performed through satellites and terrestrial repeater networks. Several unique channels are available, and even if a vehicle changes locations, the same information can be received without breaks. Information such as song names, broadcast station names, etc. can be received. Also, traffic information can be received and displayed on the navigation screen.

NOTICE:
To receive audio-visual pay-type broadcasts, the customer must enter into a pay-type contract with XM Satellite Radio Inc. After entering into a contract, registration of the XM Radio ID is required. Also, if parts are replaced, the XM Radio ID must be reregistered.

11. AUTOMATIC SOUND LEVELIZER (ASL) FUNCTION OUTLINE

(a) The ASL function automatically adjusts the sound volume in order to enable clear audio quality even when vehicle noise increases (as vehicle speed increases, the volume is turned up, etc.).

Vehicle speed signals are received from the combination meter assembly and used for ASL control.

12. COMMUNICATION SYSTEM

(a) AVC-LAN OUTLINE

(1) Components of the navigation system communicate with each other via the AVC-LAN.

(2) The AVC-LAN uses a twisted pair of wires for its communication lines.

(3) The master unit of the AVC-LAN is the navigation receiver assembly.
