January Update:
Today was the first "in car" test of the reconfigured navigation unit and it worked as expected!
This means that 5 out of ~28 gauges worked as is.
With the CAN bus module (under development) an additional ~22 gauges will display live data.
Also, since this works on the G37, it will also work on the 370, as long as you have the factory navigation.
On my test bench I have reconfigured the same AV/Nav unit to be from a Murano, 370, G37 and GTR without any issues and the GTR gauges work.
Anyways, that's all for now.
I hope to have another update in a few weeks the most of the gauges working
