NAVIGATION SYSTEM
6. TIPS FOR THE NAVIGATION SYSTEM
1. GPS (GLOBAL POSITIONING SYSTEM)
The Global Positioning System (GPS) de-
veloped and operated by the U.S. Depart-
ment of Defense provides an accurate
current position, normally using 4 or more
satellites, and in some case 3 satellites. The
GPS system has a certain level of inaccura-
cy. While the navigation system compen-
sates for this most of the time, occasional
positioning errors of up to 300 ft. (100 m)
can and should be expected. Generally, po-
sition errors will be corrected within a few
seconds. When the vehicle is receiving signals from
satellites, the “GPS” mark appears at the
top left of the screen.
The GPS signal may be physically obstruct-
ed, leading to inaccurate vehicle position on
the map screen. Tunnel
s, tall buildings,
trucks, or even the pl acement of objects on
the instrument panel may obstruct the GPS
signals.
The GPS satellites may not send signals due
to repairs or improvements being made to
them.
Even when the navigation system is receiv-
ing clear GPS signals, the vehicle position
may not be shown accurately or inappropri-
ate route guidance may occur in some cas-
es.
LIMITATIONS OF THE
NAVIGATION SYSTEM
This navigation system calculates the
current position using satellite signals,
various vehicle signals, map data, etc.
However, an accurate position may not
be shown depending on satellite condi-
tions, road configuration, vehicle condi-
tion or other circumstances.
NOTICE
●The installation of window tinting may
obstruct the GPS signals. Most window
tinting contains some metallic content
that will interfere with GPS signal recep-
tion of the antenna in the instrument
panel. We advise against the use of win-
dow tinting on vehicles equipped with
navigation systems.

7. TIPS FOR OPERATING THE AUDIO/VISUAL SYSTEM
GX_EMVN_OM60K84U_(U)13.07.02 11:50
zMP3 (MPEG Audio Layer 3), WMA
(Windows Media Audio) and AAC
(Advanced Audio Coding) are audio com-
pression standards.
z This system can play MP3/WMA/AAC
files on CD-R, CD-RW, DVD-R, DVD-RW
discs and USB memory.
z This system can play disc recordings com-
patible with ISO 9660 level 1 and level 2
and with the Romeo and Joliet file system.
z When naming an MP3/WMA/AAC file,
add an appropriate file extension (.mp3/
.w m a / . m 4 a ) .
z This system plays back files with .mp3/
.wma/.m4a file extensions as MP3/WMA/
AAC files respectively. To prevent noise
and playback errors, use the appropriate
file extension.
z This system can play only the first session
when using multi-session compatible CDs.
z MP3 files are compatible with the ID3 Tag
Ve r. 1 .0, Ve r. 1 .1 , Ve r. 2 . 2 a n d Ve r. 2 . 3 f o r -
mats. This system cannot display disc title,
track title and artist name in other formats.
z WMA/AAC files can contain a WMA/
AAC tag that is used in the same way as an
ID3 tag. WMA/AAC tags carry informa-
tion such as track title and artist name.
z The emphasis function is available only
when playing MP3/WMA files recorded at
32, 44.1 and 48 kHz.
z This system can play back AAC files
encoded by iTunes. z
The sound quality of MP3/WMA files gen-
erally improves with higher bit rates. In
order to achieve a reasonable level of
sound quality, discs recorded with a bit rate
of at least 128 kbps are recommended.
z M3u playlists are not compatible with the
audio player.
z MP3i (MP3 interactive) and MP3PRO
formats are not compatible with the audio
player.
z The player is compatible with VBR (Vari-
able Bit Rate).
z When playing back files recorded as VBR
(Variable Bit Rate) files, the play time will
not be correctly displayed if the fast for-
ward or reverse operations are used.
z It is not possible to check folders that do not
include MP3/WMA/AAC files.
z MP3/WMA/AAC files in folders up to 8
levels deep can be played. However, the
start of playback may be delayed when
using discs containing numerous levels of
folders. For this reason, we recommend
creating discs with no more than 2 levels of
folders.

zThis is the international standard for the for-
matting of CD-ROM folders and files. For
the ISO 9660 format, there are 2 levels of
regulations.
z 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.)
z 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.
z Playlists created using “WINAMP” soft-
ware have a playlist file extension (.m3u).
z MP3 is an audio compression standard
determined by a working group (MPEG) of
the ISO (International Standard Organiza-
tion). MP3 compresses audio data to about
1 /10 the size of that on conventional discs. z
WMA (Windows Media Audio) is an audio
compression format developed by
Microsoft
®. It compresses files into a size
smaller than that of MP3 files. The decod-
ing formats for WMA files are Ver. 7, 8 and
9.
z AAC is short for Advanced Audio Coding
and refers to an audio compression tech-
nology standard used with MPEG2 and
MPEG4.

same time, the other party may not hear
what has been said. (This is not a malfunc-
tion.)
●Keep call volume down. Otherwise, the
other party’s voice may be audible out-
side the vehicle and voice echo may
increase. When ta lking on the phone,
speak clearly towards the microphone.
