Aux not showing up
I found this video but i was wondering if i need to just buy a 3 cabled female AUX cable or do I need a Mercedes made one?
I was also wondering how I could program the AUX in since i only have MP3, CD and radio. Do i need Star Diagnosis DAS Xentry? Are there any other alternatives like engineering mode?
I found these two which one comes with the cable, but is it the correct cable?

and this came with the coder too but does it really work?

Are there any other low cost options (100 euro-ish)?
My car is a 2006 W221 and has NTG 3.0 and is a pre-facelift ofc.
Would appreciate the help
