So you're confirming that adding the buttons is much easier than the 350z, don't need to remove the wheel or airbag? If so that is excellent.

Obviously though that brings me back to the harness issue. The poster above seems to indicate it was a 10 minute job, leading me to believe the harness is in place, just unused. Can someone confirm that has a Nismo (or non Bose Z) if that cable exists in the trunk? I don't have immediate access to the car.

Thank you

I've only glanced through the audio/nav section but, IIRC, the switches use some kind of coding to communicate with the radio (each switch is not hard-wired to the radio as a discrete input), so the new sw assembly may use the same wiring. But my memory ain't what it used to be. Let us know what you find out.

I never said that, what i am saying is adding the buttons to the wheel would be the easier part than figuring out how to get them to work. The only way the harness would be in place is if it had the bose system. In which case the buttons should already be there if memory serves me correctly.

Figuring out how to get them to work is easy, there are several links on this forum describing exactly how - takes a few pins to short and a manual re-program of the Access unit.

I've just had a look in the 2010 Nismo trunk area, and see what appears to be a harness for an amplifier and a subwoofer, so I may be in luck! Still looking...

Well, that harness appears to be 16 pin, and the bluetooth harness is 30+ pins from the pictures I'm finding online... maybe I'm SOL here. I wish I knew how the user above did this!!

that is IF you already have them installed and you have the bose unit we are talking about if you want to add them to the base model where they are not already installed.

Again, to try and simplify my question:

Does this harness exist on a 2010 Nissan 350z Nismo edition with no Bose / no Navi.

I hate to sound like a broken record, but the guy above said he did this in 10 minutes leading me to believe the harness was there, or he figured out a different way to get the signals to the Axxezz device.

No

Thank you! Repped.
