I pulled my USB drive out to do something, don't remember what. I noticed something below the usb slot. My usb input for my radio is IN my armrest which is cavernous. I can barely see the USB slot from the drivers seat. Anyway, what I noticed was small and dark. Turns out it is an AUX port directly below my USB port. SO!!!! I grabbed my FiiO M11S and plugged it into the AUX port. I now have access to my entire music library!!! I am so happy!!! Not sure how I missed that AUX port or if I just forgot about it or what but it works flawlessly. It's louder than the CD, USB and Radio. For some reason the AUX input goes to volume 45 while the other 3 go to 40. Whatever, it works well!!!
