Finally, the found what I was looking, I have nen Audi A4 B8 Bj. 2011 MMI and I can say it works flawlessly, I would not have thought, because the price is not to beat. Who much and long investigated the custom is no longer looking for here long after such a cable, the original costs about 30, -. The advantage of this cable is that it is kopatibel with AMI MDI and MMI, the heist who buys later NEN new car to use the opportunity of this cable on. Cable connected USB stick ran in the MMI menu at Audi go on Source Select the recognized Stick and simply click on the desired Music and off you go. As I said very good value, for money and highly recommended. Did not think it NEN for this price are the cable with multiple interfaces compatible. So do not be shy Those looking for cheap NEN cable MMI to USB is hereby well served. The reading of the music files also did not last long. Property me before Audi Original Adapter for Audi Music Interface USB AMI ordered, of course not worked. I hope it works for you as well, and then a lot of fun.
