ipod usb integration

Hi guys

i have the new ipod touch 5th gen that has the lightning port and need a cable that i can plug into my usb port in my bmw so that i can listen to music from my ipod and use all of its control functions.

the white apple cable that came with the ipod does not seem to work.

i have heard that the Y cable is what i need but i think it only comes in the 30 pin (bigger) ipod pin. need one for the new smaller lightning port.

any help would be greatly appreciated

regards
