USB Mode
When a portable media device, such as an iPod® with its available cable or portable mass storage such as a USB thumb drive, is connected to the vehicle audio system through the USB ports, audio from the device can be played through the vehicle speakers. Functions such as volume, seek, fast forward, pause, etc. can be controlled by the vehicle audio controls.
When playing media files stored on a mass storage device such as a flash drive, the SYNC® system only plays files that do not have Digital Rights Management (DRM) protection.
In addition to audio information (track length, track number, etc.), metadata (information such as artist, album title, song title, and genre) may also be sent to the APIM from a device connected to the USB ports. The APIM uses the metadata to create indexes that can be used to sort for particular music based on the customers preferences. When a new media device is connected to the SYNC® system, the APIM automatically indexes the information. This may take several minutes depending on the amount of data on the device, and is considered normal operation. When a device that was previously connected to the SYNC® system is reconnected, the APIM updates the index rather than creating a new one. This reduces the time needed to index the device.
The USB ports can also be used to upload vehicle Application upgrades to the APIM from a mass storage device such as a flash drive.
Image files can be saved to the APIM from a USB device in order to be used as wallpaper backgrounds displayed on the FDIM .
