This is the ipod connectivity cord as mentioned above. Part number 61120440812, this ones obviously cheaper then the OEM BMW or even some of the aftermarket ones from ESS or any other reputable BMW supplier. Those more expensive cords may be nicer, but this one will probably work fine for years, and even if it doesn't, I have 2, so when the first one dies, just switch it out.
The connectivity has a bit to be desired, every time you restart the car, you have to select "random" in the settings as on restart, it will play the songs in the unshuffled order they are in the ipod, even if the ipod is on random. This seems silly to me, but its better then running it through the aux input and having to control song changes on the ipod itself. I dig wheel controls
