you should simply be able to go to infinitis website and look and build a car or perhaps they have those functions listed on the promo page of the site.
you could also download the 2013 operators manual.
the only thing i miss is the dim outside mirrors.
the backup collision is a second wish
the dvd display is not really that big of a deal. its a nice GUI for sure, but the same functions are on the remote.
the infiniti helper thingy , for me, is not something i would use. i am connected in the car via cellular and i have wifi avail to me from my handset to service my tablet, so i am always able to get what i need.
of course others see more benefits in other features than some, so YMMV.
