First post here hopefully this isn't too remedial but I can't figure this out-

So I have a 2011 A3 TFSI with the premium trim plus blue tooth package. In the armrest there are three input areas- a regular charger, a 12 volt charger, and what looks like an input for an audio jack.

So I bought an audio cable and connected my ipod to the jack- but on the stereo there doesn't appear to be an option to switch to an AUX or INPUT / OTHER DEVICE setting. All I have is AM, FM, CD, and SAT. Am I missing something?

 

ok- figured it out. Just incase anyone else is as dumb as I am all you have to do is hold down the CD button.
