An auxiliary device, such as an iPOD or a USB flash drive can be connected to the audio system via the connector in
the center console storage compartment.
A sound source must be chosen, depending on the device that has been connected:
1. Use MODE to select iPOD or USB. The text
2. Connect the device to the connector in the center console storage compartment (see the illustration).
The text LOADING will be displayed while the system indexes the files on the device. This may take a short time.
When indexing has been completed, track information will be displayed, and the desired track can then be selected.
Tracks can be selected in two ways:
Turn the Tuning knob (no. 4 in the illustration on
Use the right or left arrow keys on the navigation control (no. 5 in the illustration on
track. The arrow keys on the steering wheel keypad can also be used in the same way.
NOTE
The system supports playback of files in the most common versions of formats such as mp3, wma, and wav.
However, there may be versions of these formats that the system does not support.
USB flash drive
To simplify the use of a USB flash drive, it is 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 anything other than compatible music files.
MP3 player
Many 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 system must be set to USB Removable device/Mass Storage Device.
iPod
An iPod receives current and its battery is charged through the connecting cord. However, if the iPOD's battery is
completely drained, it should be recharged before the iPOD is connected to the audio system.
NOTE
When an iPOD is used as a sound source, the vehicle's audio system has a menu structure similar to the one in the
iPOD. See the iPOD's manual for detailed information.
For further information, refer to the accessory manual USB/iPOD Music Interface.
