Here it is, finally installed in the car. I've got a lot of tweaks to do with the software, but i am happy with the end result.

I ended up using the following for the fabrication:

Lid Cluster from a 2006 350Z w/ NAV (P#68260-CF42A)
Finisher from a 2003 350Z dash
Pastic Sheet Styrene from Evergreen models (to create the "cover" where the Nissan nav controls would be)

I think it turned out pretty good. Now it's time to go drive and listen to music!
