to index the files on the drive if it contains any-
thing other than compatible music files.
NOTE
•The system supports removable media
that uses the USB 2.0 standard and the
FAT32 file system. It can index up to
1,000 folders and a maximum of 254
sub-folders/files for each folder. How-
ever, the highest folder level can sup-
port up to 1,000 sub-folders/files.
•When using a longer type of USB
device, connecting it with a USB
adapter cable will help reduce mechan-
ical wear on the USB socket and on the
device.
MP3 playerMany MP3 players have a file indexing system
that is not supported by the vehicle's audio
system. In order to use an MP3 player, the sys-
tem must be set to USB Removable device/
Mass Storage Device.
iPodŸ
An iPodŸ receives current and its battery is
charged through the connecting cord. How-
ever, if the iPod's battery is completely
drained, it should be recharged before the
iPodŸ is connected to the audio system.
NOTE
When an iPodŸ is used as a sound source,
the vehicle's audio system has a menu
structure similar to the one in the iPod
Ÿ. See
the iPod's manual for detailed information.
For further information, refer to the accessory
manual USB/iPodŸ Music Interface.
Adjusting volume for an external deviceThe volume of an external device may be dif-
ferent from the volume of the internal sound
sources such as the CD player or the radio. It
the external device's volume is too high, the
quality of the sound may be impaired. To help
prevent this, adjust the external device's input
volume as follows:
1. While playing the radio or a CD, lower the
audio volume to about one-quarter.
2.
Switch to
AUX mode on the audio system
by pressing the MODE button.
3. Connect the headphone output from your
music player to the AUX input using a cable
with a stereo 3.5 mm miniplug at both
ends.
4. Set your music player's headphone vol-
ume to three-quarters using the player's
volume controls.5.
Press MENU on the audio system, and
navigate to
AUX input volume.
6. Turn the volume knob to raise or lower the
AUX input volume until you hear music at
a comfortable level.
7. If there is distortion, lower your music play-
er's headphone volume until the distortion
goes away.
8. Finally, exit the menu and adjust the audio
volume to a comfortable level.
BluetoothŸ streaming audio (BT)The vehicle's audio system is equipped with
BluetoothŸ, which makes it possible to play
streaming audio files from a BluetoothŸ device
such as a cell phone or personal digital assis-
tant (PDA). Navigation and control of the device
can be done through the vehicle's center con-
sole control panel or the steering wheel key-
pad. On certain external devices, it is also pos-
sible to change tracks from the device itself.
In order to listen streaming audio, BT must be
selected as a sound source (see page 247) and
a Bluetooth
Ÿ device must be connected
(paired) with the audio system. See page 264
for more information.
