4-6.Tips for operating the audio/visual system
●The use of a cellular phone inside 
or near the vehicle may cause a 
noise from the speakers of the 
audio/visual system which you are 
listening to. However, this does 
not indicate a malfunction.
Usually, a problem with radio 
reception does not mean there 
is a problem with the radio   it 
is just the normal result of condi-
tions outside the vehicle.
For example, nearby buildings 
and terrain can interfere with FM 
reception. Power lines or phone 
wires can interfere with AM sig-
nals. And of course, radio sig-
nals have a limited range. The 
farther the vehicle is from a sta-
tion, the weaker i ts signal will 
be. In addition, reception condi-
tions change constantly as the 
vehicle moves.
Here, some common reception 
problems that probably do not 
indicate a problem with the radio 
are described.
■FM
Fading and drifting stations: 
Generally, the effective range of  FM is about 25 miles (40 km). 
Once outside this range, you 
may notice fading and drifting, 
which increase with the distance 
from the radio transmitter. They 
are often accompanied by dis-
tortion.
Multi-path: FM signals are 
reflective, making it possible for 
2 signals to reach the vehicle’s 
antenna at the same time. If this 
happens, the signals will cancel 
each other out, causing a 
momentary flutter or loss of 
reception.
Static and fluttering: These 
occur when signals are blocked 
by buildings, trees or other large 
objects. Increasing the bass 
level may reduce static and flut-
tering.
Station swapping: If the FM sig-
nal being listened to is inter-
rupted or weakened, and there 
is another strong station nearby 
on the FM band, the radio may 
tune in the second station until 
the original signal can be picked 
up again.
■AM
Fading: AM broadcasts are 
reflected by the upper atmo-
sphere   especially at night. 
These reflected signals can 
interfere with those received 
directly from the radio station, 
causing the radio station to 
sound alternately strong and 
weak.

●To avoid damage to the 
audio/visual system:
• Be careful not to  spill beverages 
over the audio/visual system.

Station interference: When a 
reflected signal and a signal 
received directly from a radio 
station are very nearly the same 
frequency, they can interfere 
with each other, making it diffi-
cult to hear the broadcast.
Static: AM is easily affected by 
external sources of electrical 
noise, such as high tension 
power lines, lightening or electri-
cal motors. This results in static.
■SiriusXM
 Cargo loaded on the roof lug-
gage carrier, especially metal 
objects, may adversely affect 
the reception of SiriusXM Sat-
ellite Radio.
 Alternation or modifications 
carried out without appropri-
ate authorization may invali-
date the user’s right to 
operate the equipment.

*1: Variable Bit Rate (VBR) compati-ble
*2: Only compatible with Windows Media Audio Standard
 MP3 (MPEG Audio Layer 3), 
WMA (Windows Media Audio) 
and AAC (Advanced Audio 
Coding) are audio compres-
sion standards.
 This system can play 
MP3/WMA/AAC files on USB 
memory.
 MP4, WMV and AVI files can 
use the following resolutions: 
128x96, 160x120, 176x144 
(QCIF), 320x240 (QVGA), 
352x240 (SIF), 352x288 
(CIF), 640x480 (VGA), 
720x480 (NTSC), 720x576 
(PAL)
 When naming an 
MP3/WMA/AAC file, add an 
appropriate file extension 
(.mp3/.wma/.m4a).
 This system plays back files 
with .mp3/.wma/.m4a file 
extensions as 
MP3/WMA/AAC files respec-
tively. To prevent noise and 
playback errors, use the 
appropriate file extension.
 MP3 files are compatible with 
the ID3 Tag Ver. 1.0, Ver. 1.1, 
Ver. 2.2 and Ver. 2.3 formats.

disc title, track title and artist 
name in other formats.
 WMA/AAC files can contain a 
WMA/AAC tag that is used in 
the same way as an ID3 tag. 
WMA/AAC tags carry infor-
mation such as track title and 
artist name.
 The emphasis function is 
available only when playing 
MP3 files.
 This system can play back 
AAC files encoded by iTunes.
 The sound quality of 
MP3/WMA files generally 
improves with higher bit rates.
 m3u playlists are not compati-
ble with the audio player.
 MP3i (MP3 interactive) and 
MP3PRO formats are not 
compatible with the audio 
player.
 The player is compatible with 
VBR (Variable Bit Rate).
 When playing back files 
recorded as VBR (Variable Bit 
Rate) files, the play time will 
not be correctly displayed if 
the fast forward or reverse 
operations are used.
 It is not possible to check fold-
ers that do not include 
MP3/WMA/AAC files.
 MP3/WMA/AAC files in fold-
ers up to 8 levels deep can be 
played. However, the start of 
playback may be delayed  when using USB memory 
containing numerous levels of 
folders. For this reason, we 
recommend creating USB 
memory with no more than 2 
levels of folders.
 The play order of the USB 
memory with the structure 
shown above is as follows:
 The order changes depending 
on the personal computer and 
MP3/WMA/AAC encoding 
software you use.

1584-6. Tips for operating the audio/visual system
4RUNNER_NAVI_(U)
■ID3 tag
 This is a method of embed-
ding track-related information 
in an MP3 file. This embed-
ded information can include 
the track number, track title, 
the artist’s name, the album 
title, the music genre, the year 
of production, comments, 
cover art and other data. The 
contents can be freely edited 
using software with ID3 tag 
editing functions. Although 
the tags are restricted to a 
number of characters, the 
information can be viewed 
when the track is played back.
■WMA tag
 WMA files can contain a 
WMA tag that is used in the 
same way as an ID3 tag. 
WMA tags carry information 
such as track title and artist 
name.
■MP3
 MP3 is an audio compression 
standard determined by a 
working group (MPEG) of the 
ISO (International Standard 
Organization). MP3 com-
presses audio data to about 
1/10 the size of that on con-
ventional discs.
■WMA
 WMA (Windows Media Audio) 
is an audio compression for- mat developed by Microsoft
®. 
It compresses files into a size 
smaller than that of MP3 files. 
The decoding formats for 
WMA files are Ver. 7, 8 and 9.
