2010 Volkswagen Jetta Aux input?

I'm unable to connect my Ipod to the car. In the center console there's a jack for the fourth generation iphone. But when it's plugged in, it doesn't connect. There's no button on the radio that says aux or anything like that. The only options are FM, AM, and CD and MIX CD. Sometimes when i'm on the CD option is says NO MAGAZINE which for a while I was assuming meant no other device connected but I seriously don't know what to do. It has bluetooth and It allows me to make calls through the car but I'm not sure how to play music through bluetooth either.I've read the manual many times but It doesn't say anything helpful. I'm really frustrated. Could someone please help me?

I have the same car there should be a spot on the console outside of it with a aux input but I have my phone synced with blue tooth than go to the settings in your phone find you car than options and it'll say use for phone call and another one use for media check both boxes than play music on your phone and than click the media button that's what I do hope it works
