This audio system can operate the audio files on a USB flash memory device with the same controls used for the in-dash disc changer. To play a USB flash memory device, connect it to the USB adapter cable in the upper glove box, then press the CD/ AUX or AUX button.
The audio system reads and plays the audio files on the USB flash memory device in MP3, WMA or AAC* formats. Depending on the format, the display shows MP3, WMA or AAC when a USB flash memory device is playing. The USB flash memory device limit is up to 700 folders or up to 65535 files.
*: Only AAC format files recorded with iTunes are playable on this audio unit.
The recommended USB flash memory devices are 256 MB or higher, and formatted with the FAT file system. Some digital audio players may be compatible as well.
Some USB flash memory devices (such as devices with security lockout features, etc.) will not work in this audio unit.
NOTE:
Do not use an extension cable to the USB adapter cable equipped with your vehicle.
Do not connect your USB flash memory device using a hub.
Do not use a device such as a card reader or hard drive as the device or your files may be damaged.
Do not keep a USB flash memory device in the vehicle. Direct sunlight and high heat will damage it.
We recommend backing up your data before playing a USB flash memory device.
Some devices cannot be powered or charged via the USB adapter. If this is the case, use the accessory adapter to supply power to your device.
Depending on the software the files were made with, it may not be possible to play some files, or display some text data.
Depending on the type and number of files, it may take some time before they begin to play.
