SYSTEM DESCRIPTION

NAVIGATION SYSTEM OUTLINE

(a) 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)

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.

(b) Autonomous navigation

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

(1) Gyro sensor

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

(2) Vehicle speed signal

Used to calculate the vehicle driving distance.

(c) 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.

(d) 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 internal memory and the vehicle position is set onto the most appropriate road.

USB AUDIO SYSTEM FUNCTION OUTLINE

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 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.

(d) Noise problem

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

"HD Radio" FUNCTION OUTLINE (w/ HD Radio Function)

(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.

SiriusXM FUNCTION OUTLINE (w/ SXM Function)

(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.

NOTICE:

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.

HINT:

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.

AUTOMATIC SOUND LEVELIZER (ASL) FUNCTION OUTLINE

(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.

DYNAMIC VOICE RECOGNITION FUNCTION OUTLINE (w/ Dynamic Voice Recognition Function)

(a) There are two types of voice recognition; the voice recognition function uses voice recognition data stored in the onboard device.
