Code B127A Chevrolet Description

The rear seat entertainment system has an auxiliary input assembly that contains a USB port, an SD card reader, RCA-type audio/video jacks, and a wired headphone jack with volume control. Refer to the Owner's Manual for information on compatible devices and supported media types/formats.
The USB port and SD card reader slot interface with a hub device, internal to the assembly. The assembly receives fused battery voltage and ground from the harness to power the internal hub device as well as provide additional amperage to power USB devices.
The internal hub device interfaces directly with the disc player via a standard USB cable. A Mini-type USB connector is used to connect the cable to the disc player and the auxiliary input assembly. Mini-type USB male-to-female connections are 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 rear seat entertainment system from portable media players or a USB storage device (memory stick/ flash drive). The rear seat entertainment uses the SD card reader as a mass storage device, like a USB storage device.
Once a supported device is connected to the USB port or SD card reader, the device may be sourced to one or both of the rear displays using the remote control.
