So people are saying that using the Apple USB connnector vs the BMW Y-cable (that comes with the car) for an iPod produces better sound quality on the speakers?
D/A means digital/analogue converter
the mp3 song i am playing is digital
its being converted into analogue to be reproduced by the speakers
if you use the BMW cable
the conversion is done inside the ipod.
the ipods, although i love them, are not known to have the best sound quality
if you use the apple cable (the one that comes with your ipod)
the conversion is done inside the head unit
which based on my experience
sounds better than the conversion done inside the ipod

keep in mind this is only for songs without Digital Rights Management (DRM)
so if you bought all your songs from itunes (except the last few months, they now have drm free)
they will only work if the ipod does the conversion, i.e you have to use the bmw cable
