CDMM_AUX_HU

CDMM_USB_AUDIO_SINGLE

CDMM_USB_AUDIO_DOUBLE_0B

Note: Coding these changes will disable the USB data port and aux input inside of the console. It is a concession for having a higher quality audio source. If you do not want to code, you can skip this step and run the 3.5mm cable as shown in the video, but be aware there is some audio degradation using this approach.

I have a question regarding these modifications. I understand what the first modification is doing, but why are the other two necessary? It sounds like its disabling the usb ports in the center console and the glovebox. Why is that necessary to run AUX Audio through the quadlock connector directly?
