I only use the USB port with a 32GB memory stick loaded with 256kbps MP3's encoded with LAME codec. It blows HD-Radio/Sirius out of the water.

My point is, if you have the iPod you should probably use the USB input and not the AUX input since it should yield better sound quality. But someone correct me if I'm wrong since I don't use an iPod.
In our '09 35d when I unplug the Aux input part of the Y cable ---- the sound stops

AFAIK the USB part of the BMW Y cable is only used to charge the iPhone and control the iPod app.
