you said CAN , i bet you meant CAN'T or CAN NOT. right?
the AUX port is just a line input, analog audio input,
it dont know MP3 .
it only amplies the analog audio found there.
you connect any device, to AUX. push play on the device.
then put car radio in to AUX input mode and play. the audio.
that is all there is to it.
the external device does all the heavy lifting, reading a file, and decoding it (mp3 decode) and then sends raw analog audio out.

the cable is sold and radioshack, or walfart or many other stores,
Target, most MP3 players, come with this cable,
they use mini phone plugs, stereo, type,. (3 contacts)

The ford radio has two Aux out puts. one of them being a usb jack. if that is the input you are trying to use plug the device in and use the voice command and ask it to select usb.

07 Ranger and Mustang were the first vehicles to come with a factory installed aux jack. All prior vehicles had to have one installed. I believe the Ford kit was called Trip Tunes.

This sounds like you do not have full usb functionality and it is diverting to the aux input. when aux is used you have to control the play and sound etc from the actual mp3 player and not the audio controls

It is not in the vehicle , if you have the external cd changer,
the cd changer can be unplug, to install the auxiliary audio input,
this is what you need volswagen aux interface

for ipods use this ipod interface full ipod controls from the volkswagen radio

NO there is no line input jack the AUX button was made for the rear video system
but there is a audio adapter you can use go here

I'am an M.B. tech- I do not beleive that this radio is mp3 compatable- iknow that the input you are refering to is used for ipod use. It very well could be that the head unit has to be programed(basically informed0 for an mp3- i would call the service dept. and ask to talk to ther best audio tech savay mechanic. Most likley the service writer wouldn.t know or give you false information because they do not stay on top of all the little tecnical changes. This fiber optic system has many programing features- most have to be done with as sds laptop(dealer software only) good luck

If you have no visibility of the jack on your head unit then you do not have one. Therefor if you want to run something aux you need to replace with an after market head unit with an aux jack.
