Try to get AUX 325i

Good morning, I own 325I automatic, and would like to DIY and get AUX, but before I order something I thought to ask experts some questions, I attached picture of exactly what i have the radio, the radio cables and plugs, the phone and the cables as well.

I thought of removing the phone since it's useless, because it need a mobile card with a different number not same my number.



Do i have to buy a AUX cable and connect it from the radio itself or can use the phone cable?



will it work for me or not?



thank you
