Bought a Tesla style stereo to upgrade my SE au/NZ new spec 2010 d4. It includes stereo can bus decoder that works for reverse camera config etc. Has a little speaker for chimes. Seems to work for most things. Will look into whether I relocate the other screen for date. One cut required to dash. Very high performance unit so far. I got the DVR and tyre pressure monitoring kits too.
I will attach some pictures.
