I get a slightly worse sound when using the aux plug versus cd/hard drive. Part of it is 60hz noise from charging(was much worse in my Mazda). The other thing is background hiss caused by the output on the iPhone not being a true line balanced output. The best I can do is turn eq off on the iPhone, max out the volume, and turn the aux volume setting in idrive down until the hiss is manageable. I feel there is still a slight dullness to the sound, but it's the same for any car that I've used an analog input to connect to an iPod.
