Does my Nav unit not have voice commands?
 

I live in South Africa
I have a 2011 Coupe with Nav, seems to be equilavent to your Touring spec.
I have Nav with touch screen, music box, usb, rca. However I don't seem to see the voice command option, my phone button on the steering wheel has a "phone up" and 'phone down" icon, not a "speak" icon. Is this a configuration you have seen before? I do remember the one 2010 model I looked at had voice, I can't understand why it would not be on mine.
