Code B124B Buick Description
The internal hub device interfaces directly with the human-machine interface control module via a standard USB cable. A Mini type of USB connector is used to connect the human-machine interface control module and the USB receptacle. Standard USB male-to-female connections are typically used for connecting USB cables together where an in-line connection is required. An in-line cable connection is typically found between the console and the I/P harness.
The USB port allows connectivity to the infotainment system from portable media players or a USB storage device (memory stick/ flash drive). When a device is connected to the USB port, the system detects the device and switches to USB as the audio source. Once connected, the device can be controlled by the radio controls.
Not all portable media player devices or file types are compatible. Refer to the owner’s manual for information on USB devices, control, and operation.
