Can't your phone do voice dialing? I understand you want the steering control function of press, speak the name and it dials. You should still have that function from your phone if it came with it. The iPhone does and you will still be using the car speakers and dynavin mic when it starts dialing and your call is connected. Not a deal breaker for me anyway since I still have that function.
I am getting this at just the right time. October 1st the law takes affect that requires Bluetooth here in MD
