Firstly, Hi and thanks to everyone who has provided all the invaluable information about the great 350z.
I have replaced my std SAT NAV with an alpine unit, as I required it for european travel. It is so much better than the std Nissan Birdview. I linked it with an Alpine 6.5" Screen that slotted in to replace the birdview screen.

I also changed my head unit.
