Hi Guys,
I made the discovery about the 2011 GT-R and posted the details on the GT-R forum
HERE
I then made the kits available
HERE and offered both a complete kit (with camera) and one with just the harness.
I've been contacted by a couple of 370Z owners (including DeLRo) and working with them we've established that the 370Z with Satnav is the same as the GT-R. There are some minor differences in the wiring but the same harness approach will work.
Let me know if you want some help either in creating a 370Z harness or just sharing how to do it.
Cheers,
Brian
