NAVIGATION / MULTI INFO DISPLAY: NAVIGATION SYSTEM: SYSTEM DESCRIPTION; 2019 - 2020 MY Sienna [08/2018

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.

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.

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

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

This method detects the absolute vehicle position using radio waves from GPS satellites.

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 (disc player disc) and the vehicle position is set onto the most appropriate road.

(a) 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 and audio.

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.

NOTICE:

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.

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

NOTICE:

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.
CD-Rs and CD-RWs are more easily affected by a hot and humid environment than discs used for normal audio CDs. For this reason, some CD-Rs and CD-RWs may not play.
If there are fingerprints or scratches on a disc, the disc may not play or the disc may skip.
Some CD-Rs and CD-RWs may deteriorate if they are left in the cabin for a long time.
Keep CD-Rs and CD-RWs in an opaque case.
DualDiscs that combine DVD recorded material on one side with CD digital audio material on the other cannot be played.
Keep discs away from dirt. Be careful not to damage discs or leave fingerprints on them.
Hold discs by the outer edge and center hole with the label side up.
Leaving a 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 discs away from direct sunlight. (Exposure to direct sunlight may cause deformation of a 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) disc.
Do not use 3 in. (8 cm) discs either with or without adaptors.

HINT:

When it is cold or raining, if the windows fog up, mist and condensation may form in the player. In such cases, a disc may skip or stop in the middle of play. Ventilate or dehumidify the cabin for a while before using the player.
A disc may skip if the player experiences strong vibrations when the vehicle is driven on rough roads or similar uneven surfaces.

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.
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.

(b) "Bluetooth" is a wireless connection technology that uses the 2.4 GHz frequency band.

The communication performance of "Bluetooth" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity or antenna capacity.

(1) The "Bluetooth" built-in radio and display receiver assembly and a "Bluetooth" compatible cellular phone* can be connected using a "Bluetooth" wireless connection. This enables the use of the hands-free function on the cellular phone even if the phone is in a pocket or bag. For this reason, it is not necessary to use a connector or cable to connect the cellular phone.

*: Some versions of "Bluetooth" compatible cellular phones may not function properly.

(2) The hands-free function uses a "Bluetooth" wireless connection. A "Bluetooth" wireless connection can be affected by uncertain elements, such as vehicle location, time of day, etc. Therefore, problems related to establishing connection may be caused temporarily by "Bluetooth" connection conditions. It is necessary to check the frequency of occurrence, connection conditions using another cellular phone, etc. when performing diagnosis.

(1) The "Bluetooth" built-in radio and display receiver assembly and a "Bluetooth" compatible portable audio player* can be connected using a "Bluetooth" wireless connection. This enables files stored in the portable audio player to be heard from the vehicle speakers. In addition, operations such as play/stop can be performed directly from the radio and display receiver assembly.

*: Some versions of "Bluetooth" compatible audio players may not be able to be connected via the "Bluetooth" function, or music may play, but functions available using the radio and display receiver assembly may be limited.

The amount of remaining battery charge displayed on the radio and display receiver assembly may be different from that of the "Bluetooth" device.

(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.

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.

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.

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.

Fade out is caused by objects (buildings, mountains and other large obstructions) that deflect 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 be deflected.

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

(a) The "HD Radio" system is a radio system that broadcasts in the IBOC (In-Band On-Channel) form that the iBiquity Co. has developed. By expanding the bandwidth per channel of conventional FM/AM bands, digital audio and data signals are additionally transmitted.

"HD Radio" technology is manufactured under license from iBiquity Digital Corporation. U.S. and Foreign Patents. "HD Radio" and the HD and HD Radio logos are proprietary trademarks of iBiquity Digital Corporation. Also, traffic and weather information can be received and displayed on the navigation screen.

(a) SiriusXM (SXM) satellite radio is a satellite digital radio broadcast provided by SiriusXM 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.

To receive pay-type broadcasts, the customer must enter into a pay-type contract with SiriusXM Satellite Radio Inc. After entering into a contract, registration of the Radio ID is necessary. Also, if parts are replaced, the Radio ID must be re-registered.

When disconnecting the cable from the negative (-) battery terminal, the broadcast station logo data will be initialized. It takes a while for the broadcast station logo data to be updated to the latest data.

(a) Customization of functions can also be performed on the multi-display screen. Refer to Owner's Manual for further information on customizable items for the navigation system.

(a) The Automatic Sound Levelizer (ASL) function automatically adjusts the audio system volume in order to compensate for increased vehicle noise (vehicle noise tends to increase as vehicle speed increases). The ASL adjusts the volume based upon vehicle speed signals sent from the combination meter assembly.

(a) There are two types of voice recognition; the voice recognition function uses voice recognition data stored in the onboard device. The other is communication based and uses voice recognition data sent from communication with the DCM (telematics transceiver) as audio signals to be stored at the center.

Refer to the TOYOTA ENTUNE SYSTEM for information about communication based voice recognition.

(a) With a compatible portable device connected via "Bluetooth", this function allows the system to interface directly for voice recognition functions. The steering pad switch assembly is operated to start the Mobile Assistant function and the function is operated by using voice commands.

Mobile assistant may not operate or the device may become unresponsive depending on the type of device connected, OS (iOS/Android) version or Google app version.

(a) "Wi-Fi" is a worldwide wireless communication standard widely used as a short range communication tool.

(b) "Wi-Fi" is a trademark owned by Wi-Fi Alliance, a non-profit industry association.

The communication performance of "Wi-Fi" may vary depending on obstructions or radio wave conditions between communication devices, electromagnetic radiation, communication device sensitivity or antenna capacity.

(a) The "Apple CarPlay" function is a function that enables the head unit to operate applications on an smartphone by connecting the smartphone to the head unit using a dedicated cable.
