Just bought an '07 Passat 3.6L which has the standard Dynaudio in-dash 6 disc CD player with satellite radio (this model does not have Nav included). I want to hook up my iPhone to the stereo. I found the auxiliary input in the glove box however I cannot figure out how to switch input from CD to the aux-in. I've seen a number of posts that recommend pressing the CD button twice. Tried this last night and it just kept playing the current CD. I tried it without any discs loaded and it would immediately change back to the radio. I tried holding down the CD button but that just activates the "MIX-CD" function. Unfortunately the dealer that sold us the car "lost" the owner's manual so I'm hoping for a little help here.

I would be grateful if someone could point me in the right direction for enabling the auxiliary input.

Thanks.
