Aux input

[Sam en i]

Afternoon Gents, sorry if this has been covered a 1000 times but I couldn't quite find my answer.

I've got this HU (AUDI Concert) and it has a apple lead plugged into it, i've bought a bluetooth connection so that I can play music through it with my Samsung but where or how do I turn the radio on to receive AUX input?

I've tried pressing CD twice but it just comes up with no magazine.

Have you paired your phone with Bluetooth?

Ye it pairs up automatically but won't come through the stereo just says "no magazine" when I press CD twice.... frustrating isn't the word.

After a bit of Google though I do wonder if it's because it's a cheap adapter.
