Just got my car with the Voice Control System (AUD $1,000). Found out (in the manual that it can only do "Telephone speech control system" and not "Speech dialogue system". In the main brochure is is printed as "Voice control system for navigation system with DVD and MMI", voice control option for basic navigation,radio,CD,mobile phone and CD changer functions in conjuction with optional multifunction steering wheel. In the option price list brochure it states as Voice control system (only in combination with Navigation system) I will get to the bottom of this. Just beware of these and I will keep you inform of the outcome.
