Yes Owl, Dealer option to fit, BUT does not allow full functionality as if factory fit.
ie: factory fit allows dialing from Nav screen if fitted, this wont allow this.
It is basically a bluetooth function.

You can store up to 12 names from memory in the voice section to allow easy dialing.
Pull & hold the green button & say "dial name", "name please", "Chris" & it will dial Chris' number for you.
