I know nothing of the Holden system but I would assume there would be a blue tooth option on your Statesman's control area thingo?
stock GPS systems on factory released cars seem to be a waste of time, you're better off using the Garmin, as Holden will charge you drug money to get it set up, and then you only have a mediocre GPS system that comes with the luxury of being somehow tied to your cars controls.
I would rather have a great GPS (Garmin) that sits on my window
