there is an option which you can fit a little camera on the rear
so while u shifted into reverse, the navigator screen will show the camera's screen
Just like the one on Lexus RX330
But since the navigator is not available in Australia yet, so we definitely couldn't get.
By the way
if the navigator is available in the near future, anyone gonna get it??
The interior will definitely look better, since in the front, the centre is quite empty.
