Hi there, I've recently picked up a 2010 A4 Avant with Concert Radio (non-MMI) and AMI. I'd like to get a compatible AUX cable, but can't find definitive information on which cable to get. What I've gathered is that there are 3 cables: 4F0051510F, 4F0051510C, and 4F0051510T. My understanding is that 4F0051510C was for units with MMI, while the 4F0051510F was for units without, and the 4F0051510T replaced them both, which would mean I would need either a 4F0051510F or 4F0051510T.

But... According to some eBay sellers in regards to the 4F0051510F:

This cable only works on models that call for the 4F0051510L does not work in models that call for the 4F0051510K. Please check your manual for fitment.
Which refers to the iPod cable, and my car does have a working 4F0051510K... Meaning I would not be able to use the 4F0051510F, and would need a 4F0051510C, contrary to what others have posted.

Overall, as you can tell, this is quite confusing. If someone with a similar setup and a functioning AUX cable can weigh in, I would greatly appreciate it.

P.S.: ultimately, I'll be using the AUX cable to hook up a rechargable Bluetooth receiver... If someone has a better idea for Bluetooth music streaming on a non-MMI unit, I'm all ears.
