Auxiliary equipment
USB flash drive
To simplify the use of a USB flash drive, it is
10
advisable to only store music files on the drive.
It will take considerably longer for the system
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 and can index up to 500 folders
and a maximum of 64,000 files. The device
must have at least 256 Mb of memory.
Auxiliary sound level
254
If the external sound source's volume is too
high, the quality of the sound may be impaired.
This can be prevented by adjusting the external
sound source's input volume.
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.
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. Select AUX VOLUME in the menu and
press ENTER.
6. Adjust the volume with SELECTOR
with the up/down arrows
ENTER.
7. If there is distortion, lower your music play-
er's headphone volume until the distortion
goes away.
Finally, exit the menu and adjust the audio vol-
ume to a comfortable level.
NOTE
This cannot be done with the steering wheel
keypad.
The cover over the cup holders should be
open when an auxiliary device is connected.
