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.

*a	FM (Stereo)
*b	FM (Monaural)
*c	AM

(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.

*a	Phasing
*b	Ionosphere

(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.

*a

Multipath

(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.

*a

Fade Out

(d) 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 specific area	Multipath resulting from a change in FM frequency

"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.

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.

VEHICLE CUSTOMIZATION OUTLINE

(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 audio and visual system.

HINT:

• Items available for customization via the audio and visual system can also be customized by using the Techstream.
• Some customize parameters displayed on the Techstream will be displayed on the vehicle customization screen for the audio and visual system. Users can customize these items.

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.

"Apple CarPlay" FUNCTION OUTLINE (w/ "Apple CarPlay" Function)

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

HINT:

• Refer to the owner's manual included with the device for information about "Apple CarPlay" support.
• Some applications have a display restriction in consideration of safe driving.

"Android Auto" FUNCTION OUTLINE (w/ "Android Auto" Function)

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

HINT:

• Refer to the owner's manual included with the device for information about "Android Auto" support.
• Some applications have a display restriction in consideration of safe driving.

MOBILE ASSISTANT FUNCTION OUTLINE (w/ Mobile Assistant Function)

(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.

HINT:

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.

"Wi-Fi" hotspot OUTLINE (w/ "Wi-Fi" hotspot Function)

HINT:

• To use the "Wi-Fi" hotspot function, initial setup of the Toyota Entune App Suite function is necessary.
• To perform initial setup, refer to http://www.toyota.com/entune/.

(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.

(c) The radio and display receiver assembly uses the 2.4 GHz frequency band for "Wi-Fi" communication.

HINT:

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.
