@italiangoat - I understand what you're syaing as I have been able to do this as well. The problem that resurfaced for me is that when I turn the car off, take out the key the phone is disconnected. When I re-start the car, the AVIC unit does not see the iPhone and I have to do a re-pairing to get the connection back.
Still the same way during the early days. Are you saying your AVIC unit pairs with the iPhone automatically? This is what I am trying to resolve.
