Anyone have info on changing out a 2012 non NAV unit with a 2013 NAV unit including diagrams if possible?
Were there any major changes in these model years?
What functions will I lose by not changing the steering wheel controls?

 

There are several threads on this subject... If the sites search engine doesnt work try google...

Short answer is yes it can be done... Anything can be done lol...But it does require some minor rewiring and probably replacement of several different components and possibly changes to the backup camera controller... There is no DIY and probably never will be because of the different posibilities in years and hardware. The best advice is to look at the wiring diagrams for both cars and Read all the threads you can...

Some have claimed to have used the hardware from other Nissan and infiniti models...

I don't believe there is any changes to the steering wheel controls... But once again you will have to look at the wiring diagram...


Hope that helps
