Music from i"P"hone 4S question

Diablo3

I recently got a '12 touring, but opted not to add on the nav package, due to it being to much money.

So now the only way to do audio from the iphone through the bose speakers is that annoying aux cable. What are good quality after market addons I can get for the car that will allow me to do high quality streaming audio from the phone through USB, bluetooth, or a slot on the dashbaord where the nav package was that will allow you to simply "insert" the iphone in, plugged in....and browse through the songs using steering wheel interface, or a touch screen?

Looking for good options, from cheap to high.
