Yes, at least in the '09 Eos, the factory iPod option replaces the 3.5mm aux-in (MP3) jack in the armrest console. The iPod adapter has a slot inside the console for your iPod, but you can't access the iPod once it's in place. From what I've read and evolvingpowercat confirms, iPod owners aren't too happy with its limited functionality. The reason it's such a kludge is because all VW did was spoof the head unit into thinking it had a CD changer connected. My wife and I have generic MP3 players, so I removed the unwanted iPod adapter that came on our Eos and replaced it with a Blitzsafe aux-in adapter.
