I know this topic has been written about numerous times, but I don't have the background to understand what is being shared. I hope someone can answer in very basic terms with links to products.

I have a 2011 A3 with the Bluetooth package and an aux in port. I understand the Bluetooth only works with the phone part of the iPhone and the aux in port must be used to listen to audio.

I would like a better way to use my iPhone so that I can control it through the steering wheel controls. It would also be nice if the song info would be displayed on the radio. Preferably it would via Bluetooth but a hard wired connection would also be acceptable. Do any after market products exist? Thanks!
