Mine doesn't have navigation but I have a build in nissan sat nav Xanavi 5.1. However this has not updated what so ever.
That's why I want to replace this for a tablet, more features and still a satnav with a touchscreen in the cubby.
I can also go for the add on of the Pioneer, however they are expensive and still have my old nav in the cubby.
Also like the position of th cubby better for a satnav.
So that my reason why I want to build a tablet in my cubby where my old sat nav is.

I've got the old Xanavi 5.1 Sat Nav unit as well ... I'd be interested to know how you get on with this project as it's something that I've been thinking about for some time now ...
