My 2003 g35coupe did not have the factory navi installed. Wondering if it is possible now to install the factory one from the dealer.

For those that has the navi, does it provide you with real time fuel consumption MPG or L/100km?

 

No, you can't (at least without spending a small fortune). There is a factory wiring harness that is different between the 2 cars (those with/without navi) so your car is missing those wires.

 

Ooh I was saying that if you could... try to see if you can retrofit the 06 =D

 

It does display the fuel consumption and mileage etc....
