aux in the armrest

[ciocoiualex]

Good evening to everyone. I hope you are having a good weekend. I have a small problem and it seems that i don't find an answer anywhere. I own an Audi A5 2008 model and i have an aux lid in my center armrest but the thing is that when i bought the car i didn't check to see if it is working. Unfortunately when i just tried it a few days ago i noticed that is only the lid and is empty behind. Any idea if i can add any cable to have that auxiliar y? I mention that i have a MMI 2G without the AMI. Thank you and wish you all a wonderful day.
