I know its been done again and again but has anything been made so that i can plug it in and have the option to select AUX on the display and play music through the lead at the same volume as it would play if I was using a cd? I've been reading for over two hours and trying different methods and it seems the last option is to make my own lead with resistors and capacitors in it. I am not very clever with electronics and for what its worth the car is a 2006 (65) z4m with nav, cd changer and the ten speaker system. Thanks
