Quick note to those ringing 3-4 times a week on this. V36. if you are BUYING one of these cars BUY IT WITHOUT the navi option. I can BUILD what you want then AND make the AUS navi touch based AND integrate it back into the existing car. forget the dream of english swaps for now.
cost is a mild 4 figure exercise. I will not elaborate on price as its is really a $POA exercise.
