When I first got my Fairlady Z there was some question as to whether or not one could use an X-Trail sat nav unit in a 350Z/Fairlady Z. I bought the required kit from a breakers. I got a screen, DVD unit, DVD, button set and the wiring loom although not all of this is needed.
NOTE: THE KIT I GOT WAS FROM A 2002 XTRAIL. LATER XTRAIL SATNAV UNITS POSSIBLY HAVE A DIFFERENT CONNECTOR.
First of all I took the back trim off using this site as a guide: 350Z How-To's.
After the back trim was off I removed the JDM DVD unit. This is a comparison shot of the UK to JDM drives:

This is a shot of the connectors at the back:
Now as you can see the JDM version (bottom) has more sockets. I simply didn't connect the extra cables and have had no ill effects. If anyone knows what the extra ports do advise me and I'll update the thread.
The Fairlady Z DVD unit had mounting brackets so I had to take the brackets off using a Torx 20 and swap them over to the X-Trail unit.
I didn't need to change the screen over, just the drive so I put the car back together and moved on to the buttons.
The button layout is the same on both cars:
Unfortunately the buttons themselves are mounted very differently and aren't able to be swapped over.
I bought some small stickers and some transfers and made up the buttons myself.
Here you can see the drive is a perfect fit:
And here it is installed with the stickers over the buttons:
It's a pretty good system but it's not a TomTom. There have been features I've liked on this though. The quick stop for petrol is much easier to use than TomTom and I like the bigger screen.
