SERVICE INFORMATION
If an ipod(R) / iphone(R) related concern is verified on a vehicle while using the USB interface perform the steps in this bulletin for initial diagnosis.
NOTE:
For vehicles equipped with a Navigation system make sure to confirm whether the customer is experiencing the issue while using the USB interface or the Bluetooth(R) Audio Streaming feature. This bulletin applies only if the issue occurs while using the USB interface.
1. Power OFF/ON (restart/reset) the iPod(R) / iPhone(R)
^ The restart/reset procedure is not the same for every ipod(R) / iphone(R). The restart/reset procedures can be found at www.apple.com/support..
2. Check the USB cable
^ Some aftermarket cables can cause issues with USB connectivity. If the customer is using an ipod(R) / iPhone(R) the best cable to use is the Apple Inc. branded USB cable.
^ Make sure the cable does not have a short circuit or other concern.
3. Confirm the latest software is installed on the iPod(R) / iPhone(R)
^ Many concerns are addressed by installing the latest iPod(R) / iPhone(R) software update from Apple Inc.
^ View the software version of the ipod(R) / iphone(R) by navigating to the Settings area of the device, then selecting General > About or Settings.
^ Visit http://support.apple.com/downloads and select the applicable device to view the latest software update offered by Apple Inc.
4. If steps 1-3 have not resolved the concern:
a. Disconnect the cable from the USB interface.
b. Turn OFF the vehicle wait one (1) minute then turn the vehicle back to ACC or ON.
c. Connect a different USB device to the USB interface in the customer's vehicle then try to duplicate the concern.
