> All the headache and time to pair Bluetooth devices over a dead simple connector.

Conversely, I pair my phone once when I get the car and I never need to worry about messing with it again; it's just connected when the car starts. I don't even need to take my device out of my pocket or bag.

On top of that I get hands-free calling if someone calls while I'm driving, I get steering wheel media controls, I get voice controlled media selection (play playlist foo, play artist bar, etc.)
