Motorsport1207 has identified correct connectors.

I have used Dice since the initial product offering. I now have the Dice Mediabridge which has become the Audiovox Silverline duo. Both have the capability to connect to an iPhone using bluetooth. When connected ingoing and outgoing calls come through the radio and use existing steering wheel controls. Good excuse to get the latest iPhone.
