*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.
 This system can play only the
first session/border when
using multi session/border
compatible discs.
 MP3 files are compatible with
the ID3 Tag Ver. 1.0, Ver. 1.1,
Ver. 2.2 and Ver. 2.3 formats.
This system cannot display
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.

Audio/visual system
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.

Audio/visual system
describes the process of writ-
ing data on-demand to CD-R,
etc., in the same way that
data is written to floppy or
hard discs.
■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.
■ISO 9660 format
 This is the international stan-
dard for the formatting of CD-
ROM folders and files. For the
ISO 9660 format, there are 2
levels of regulations.
 Level 1: The file name is in
8.3 format (8 character file
names, with a 3 character file extension. File names must
be composed of one-byte
capital letters and numbers.
The “_” symbol may also be
included.)
 Level 2: The file name can
have up to 31 characters
(including the separation
mark “.” and file extension).
Each folder must contain
fewer than 8 hierarchies.
■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.

registered trademark or trade-
mark of Microsoft Corpora-
tion in the United States
and/or other countries.

■Steering switchTalk switch
Voice command system:
• Press the talk switch to start the voice command system. To can-
cel voice command, press and
hold the talk switch.
When an Apple CarPlay/Android
Auto connection is established:
• Press and hold the talk switch to start Siri/Google Assistant. To
cancel Siri/Google Assistant,
press the talk switch.
• Press the talk switch to start the voice command system.
■Microphone
 It is unnecessary to speak
directly into the microphone
when giving a command.
●Voice commands may not be rec-
ognized if:
• Spoken too quickly.
• Spoken at a low or high volume.
• The roof or windows are open.
• Passengers are talking while
voice commands are spoken.
• The fan speed of the air condition- ing system is set at high.
• The air conditioning vents are turned towards the microphone.
●In the following c onditions, the
system may not recognize the
command properly and using
voice commands may not be pos-
sible:
• The command is incorrect or
unclear. Note that certain words,
accents or speech patterns may
be difficult for the system to recog-
nize.
• There is excessive background noise, such as wind noise.
●Normally, it is n ecessary to wait
for a beep before saying a com-
mand. To enable the ability to talk
over prompts and say commands
before the beep, enable the voice
prompt interrupt function. ( P.53)
●This system may not operate
immediately after the power
switch is in ACCESSORY or ON
mode.
Voice command sys-
tem
The voice command sys-
tem enables the radio,
phone dialing, etc. to be
operated using voice com-
mands. Refer to the com-
mand list for samples of
voice commands. ( P.105)
