OK Ted, here goes. 2003 4.6is with factory nav, DSP, CD changer, no TCU or BT antenna and no BT oddment tray. So, I would like to get away from my junky BT aux unit I spliced in behind the head unit to the AUX cable and 12v. I would like to have full BT Music streaming as well as phone. Would love to be able to use the Face button to call up Siri (maybe a pipe dream but hey). What all will I need to order to make this work. It seems I need the BB module as well as an adapter cable for the phone portion and maybe a coax from CD to DSP...? Is that right? I'll check my CD changer to see if it's connected via coax or other.
