USB Radio and MP3 Functionality
The universal serial bus (USB) will be a USB 2.0 port on the radio faceplate, on the IP or in the center console. This interface will give the customer the
additional functionality of iPod®/MP3 command and control. Customers now have full radio control of the iPod/MP3 audio files via the USB cable. A single USB
connection allows digital audio transferring from the iPod to the radio. The iPod will be charging while connected to the radio. The customer will also have
playback capability with a USB memory stick (only MP3 and WMA files).
Note: Not all memory sticks are supported.
Note: Video from the iPod is NOT capable of being transferred to a Navigation radio display.
Problems with iPod Not Connecting
If the infotainment system does not operate properly when using a device connected through the USB port, this may be due to an incompatible media device.
Important: DO NOT replace the radio or multimedia interface module due to a customer device incompatibility issue.
Verify the customer's media device is validated for this system using the list below. If the customer's device is a validated device for this system, follow the SI
diagnostic procedure to isolate the fault. If the customer's device is not on the validated device list, explain to the customer that their particular unit is not
compatible with the system.
Troubleshooting Tips for iPod Devices
1.
Verify the version of the iPod/MP3 to confirm that it is supported.
2.
Unplug and re-insert the iPod to verify the customer concern.
3.
Verify the battery charge of the iPod. A low battery condition on the iPod may not allow it to connect to the radio. The iPod may need to be charged
before it can be controlled by the radio.
4.
If the customer receives a "Device Not Supported" message on their radio or is having general iPod/MP3 connection issues (and they have a
supported device), they may need to reset their iPod. To reset the iPod:
5.
•
For the iPod nano® and iPod classic®, toggle the Hold switch on and off (slide it to Hold, then turn it off again). Press and hold the Menu and Center
(Select) buttons simultaneously until the Apple® logo appears, about 6 to 8 seconds. You may need to repeat this step.
•
For the iPod touch® and iPhone®: Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider.
For iPod touch and iPhone: To obtain full use capabilities of their device, it needs to be fully powered up when connecting to the USB port. If these
devices are fully powered down or in “sleep” mode, please advise the customer to press and hold the Sleep/Wake button on the top of the device for a
1
few seconds and if an unlock pass code is required, to enter the pass code as well as slide the lower “Unlock” slider.
6.
Have the customer inspect their cable for quality.
•
•
7.
Aftermarket cables can wear from use. The customer may need to purchase a new USB cable.
Verify that cable extensions are not present. The extra capacitance may cause too large a signal drop for the iPod to communicate with the radio.
If the customer receives a "Device Not Supported" message on their radio with an iPod connected (and they have a supported device), the customer
may need to download the latest firmware from the Apple website (Please visit www.apple.com for more information).

Important: These devices (and additional MP3 players) may be capable of connecting to the other USB options by internally setting the MP3 device to mass

storage class (MSC) mode. In this mode, the USB port will see the device as a flash drive. Please have the customer refer to their MP3 device manual on how
to set the device to MSC. If the device is not able to be set to MSC, the customer must use the AUX jack.
Note: MTP mode must be used in order to transfer ANY Digital Rights Management (DRM) protected content.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may
occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools,
safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that
your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.
