I technically own a 2007 RS4 but this question is about the electronics system which is common with the A4 so I thought I'd ask it here.
The OEM bluetooth support is OK but now that it's 2012 I know the newer models are equipped with much better BT support. For example, I can't stream audio from my iphone to my car unless I used a wired connection. Annoying.
What are the best suggestions out there for the latest/nicest bluetooth/audio integration?
