USB device does not function (without navigation)

NOTE:
  • Check the vehicle battery condition first (see 12 VOLT BATTERY TEST ).
  • Check the connectors for poor connections or loose terminals.
  • Check the USB device requirement:
    • Mass-storage class ready digital audio player with USB 2.0 port
    • More than 256 MB of RAM
    • Supports MP3, WMA, and AAC (encoded with the iTunes) files, DRM files are not supported
  • Not all players and player functions work with the USB adapter. Please see the owner's manual for more information. Always test the customer's USB device in a known-good vehicle of the same year and trim (if possible). Technologies change and are updated frequently which may result in that USB devices may work in newer vehicles, but not in older vehicles of the same model.
  • If UNSUPPORTED appears on the display, the vehicle is OK, there is a software problem with the USB device.
  1. Turn the ignition switch to ON (II).
  2. Turn on the audio system.
  3. Press the AUX button to select USB mode.
    NOTE: Do not connect the USB device.

    Is USB NO DATA displayed in the audio display? 

    YES  -Go to step  4.

    NO  -Go to step  14.

  4. Turn the ignition switch to LOCK (0).
  5. Connect the customer's USB device to a known-good vehicle (same year/trim) that is equipped with a USB adapter, and check the USB device operation.

    Is the USB device working properly in the known-good vehicle? 

    YES  -Go to step  6.

    NO  -If UNSUPPORTED is displayed in the audio display, the USB device may not be supported or the wrong type music files are on the device. If USB NO SONG is displayed in the audio display, the USB device may have no music files. See the owner's manual for details on USB device requirements and approved file types.

  6. On the customer's vehicle, connect the customer's USB device to the USB port.
  7. Turn the ignition switch to ON (II).
  8. Turn on the audio system.
  9. Check the USB device operation in the customer's vehicle.

    Does the USB device work properly in the customer's vehicle? 

    YES  -The system is OK at this time. Inspect the connectors of the USB device, the USB port, and the USB adapter for wear.

    NO  -Go to step  10.

  10. Turn the ignition switch to LOCK (0).
  11. On the customer's vehicle, remove the USB device.
  12. Disconnect USB adapter control unit connector B (5P).
  13. Check for continuity between USB adapter unit connector B (5P) and the USB adapter cable 5P connector according to the table.
