AudioPilot® System
AudioPilot® is the sound improving system that picks up by a microphone under the steering any noises or the
sound of music coming into the vehicle, and that uses the BOSE speaker amp. to revise the frequency feature
of music in real time in response to the frequency feature of the noise while driving and listening to music.
If low frequency area noise from vehicle is loud, it adjusts low frequency element of music to be bigger
than vehicle noise.
If high frequency area noise from vehicle is loud, it adjusts high frequency element of music to be bigger
than vehicle noise.
If vehicle noise is smaller than the setting volume, correction is not performed.

Trouble DiagnosisNKS002ED
The majority of the audio malfunctions are the result of outside causes (bad CD, electromagnetic interfer-
ence, etc.). Check the symptoms below to diagnose the malfunction.
The vehicle itself can be a source of noise if noise prevention parts or electrical equipment is malfunction-
ing. 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 then determine the cause.
Refer to "SERVICE BULLETIN NTB04-119" for the diagnosis of satellite radio.
NOTE:
Noise resulting 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 moun-
tains or buildings blocking the signal.
