So i want to fit a Aux input to my 2004 3.0 z4, ive been reading through the posts and found this: http://www.z4-forum.com/forum/viewtopic.php?f=31&t=1483 and it looks like a easy-ish way of connecting and by far the cheapest. im not fussed about controlling the music from m,y iphone itself as i always create playlist anyway. then searching through another post i found this http://www.realoem.com/bmw/showparts.do?model=DU51&mospid=49421&btnr=65_1441&hg=65&fg=95&hl=1 its the aux connector its self, but is there anywhere in the uk i can get it from? as there all in us dollars. So the question also is... is this the easiest/cheapest way to get and ipod/iphone running in my z4? thanks..
