From memory AUX was for the old 3.5mm AUX cables, the new BT ones work as a CD changer. Have you tried it on any of the CD modes?
The link you posted doesn't work, just a amazon "cant find" message in German. Are you sure it's for your model of stereo, what model do you have? Also, some are designed for DSP, most cars don't have that.
Perhaps post up your stereo spec and try the link again, someone might be able to figure out if it's the wrong product.
I used mine today; I promise it's worth the wait!
