"Bluetooth" is a trademark owned by Bluetooth SIG, Inc.
"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.
Hands-free function
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.
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.
Compatible hands-free devices
| Required "Bluetooth" specifications | Ver. 4.2 or higher |
| Compatible profiles | ·
HFP (Hands-Free Profile) Ver. 1.7 or higher ·
PBAP (Phone Book Access Profile) Ver. 1.2 or higher ·
SPP (Serial Port Profile) Ver. 1.1 or higher |
| Maximum number of hands-free devices that can be registered (including audio devices) | 5 |
The amount of remaining battery charge displayed on the radio and display receiver assembly may be different from that of the "Bluetooth" device.
"Bluetooth" audio function
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.

RADIO DESCRIPTION
Radio frequency band
Radio broadcasts use the radio frequency bands shown in the table below.
Service area
| *a | FM (Stereo) |
| *b | FM (Monaural) |
The service areas of FM broadcasts are vastly different. FM stereo has the smallest service area, and is prone to pick up static and other types of interference such as noise.
Radio reception problems
In addition to static, other problems such as "multipath" and "fade out" exist. These problems are not caused by electrical noise, but by the radio signal propagation method itself.
| *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.
| *a | Fade Out |
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.
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 |
|---|---|---|
| FM | Noise occurs while driving in a specific area | Multipath resulting from a change in FM frequency |
AUTOMATIC SOUND LEVELIZER (ASL) FUNCTION OUTLINE
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.
