Description

RELATED TO NOISE

The majority of the audio concerns are the result of outside causes (bad CD, electromagnetic interference, etc.).

The following noise results from variations in field strength, such as fading noise and multi-path noise, or external noise from trains and other sources. It is not a malfunction.

  • Fading noise: This noise occurs because of variations in the field strength in a narrow range due to mountains or buildings blocking the signal.
  • Multi-path noise: This noise results from the waves sent directly from the broadcast station arriving at the antenna at a different time from the waves which reflect off mountains or buildings.

The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunctioning.

Check if noise is caused and/or changed by engine speed, ignition switch turned to each position, and operation of each piece of electrical equipment, and determine the cause.

NOTE: The source of the noise can be found easily by listening to the noise while removing the fuses of electrical components, one by one.

Type of Noise and Possible Cause

Type of Noise and Possible Cause

RELATED TO HANDS-FREE PHONE

Symptom Cause and Counter measure
Does not recognize cellular phone connection (No connection is displayed on the display at the guide). Some Bluetooth enabled cellular phones may not be recognized by the in-vehicle phone module.

Refer to "RELATED TO HANDS-FREE PHONE (Check Compatibility)" in AV "Symptom Table".

Cannot use hands-free phone. Customer will not be able to use a hands-free phone under the following conditions:

- The vehicle is outside of the telephone service area.

- The vehicle is in an area where it is difficult to receive radio waves; such as in a tunnel, in an underground parking garage, near a tall building or in a mountainous area.

- The cellular phone is locked to prevent it from being dialed.

NOTE: While a cellular phone is connected through the Bluetooth wireless connection, the battery power of the cellular phone may discharge quicker than usual. The Bluetooth Hands-Free Phone System cannot charge cellular phones.

The other party's voice cannot be heard by hands-free phone. When the radio wave condition is not ideal or ambient sound is too loud, it may be difficult to hear the other person's voice during a call.
Poor sound quality. Do not place the cellular phone in an area surrounded by metal or far away from the in-vehicle phone module to prevent tone quality degradation and wireless connection disruption.
