Phone Control Switch Swap on Nismo
 

I have a 13' Nismo without navigation (wasn't worth $1400 :rolleyes:)

I'm learning towards installing Kenwood DDX719 headunit. iPhone can plug into that headunit and display navigation on the screen. It also has Bluetooth for streaming music or handling phone calls.

My question is....since my Nismo doesn't come with the little phone buttons (underneath volume control) on the steering controls, can the buttons be swapped easily? I'd love to be able to handle phone calls from the steering wheel (obviously not while tracking though.) :driving:

Here's a part's diagram. I don't have the specific part number, but the cruise switch w/bluetooth, w/o navigation pkg seems to run for around $55:

Because those buttons run all the way to the trunk and connect into the bose system, I would think it would not be a simple task at all. I could be wrong but I know when you want to use those buttons on an aftermarket unit, you have to go to the trunk and cut and bypass something. The instructions for this for the bose system is located on metra's website.

It would be easy to install the button, but you would need the wiring to go along with it as well and who knows what that entails.

Things are never easy are they?

No, if things are easy then their results are like tasteless.

please do it and make a DIY guide for the rest of us!

I think too add 2 buttons its a little crazy to spend all that money on bose stuff just to bypass a wire and get it to work. Just how I look at it.

I was thinking of doing the same thing. Do you really think that it would be that difficult? If the bluetooth module isn't even being used, then does it have to be installed at all? If we knew where the origin of the cable used for the bluetooth bypass was located, couldn't we do the bypass there and save a lot of work. The existing bypass method is probably more straightforward since the equipment is easily accessible from the hatch. Maybe a similar method could involve installing the buttons on the steering wheel, and then bypassing up near the steering wheel somewhere. I just don't know what the difference is in the wiring in this area when comparing a base/NISMO vs a touring.

I just performed this swap on my '09 base+sport (non nav, non bose). Took about 10mins to physically change the buttons. Crossed my fingers and went to reprogram my axxess aswc. Just doing the button remapping didn't work, although the two new buttons did change volume up and track down. So I did the full reprogram of the axxess (holding down the reset button for 10seconds and mapping each button. And now all of my buttons do what I assigned them to. Thanks to @diesel11679 for finding the parts diagram.

That's great! Are you saying that you just swapped the cruise switch and then programmed AXXESS, and that's it - call buttons now work? Were there any other wires to run? Did you go with the cruise switch w/o nav?

If so, than this is definitely on my "to do" list. Great job!!!:tup:

Glad to hear you found how to install them.I know if you usually have them you have to do a bypass in the trunk with the bose radio, given that you do not have that, just curious if you can get them running now.:tup:

hi, i have the touring version with bose with out nav system, and did the control swap, after i install a new sony stereo and aswc1, the new buttons does not work properly, one turns off the radio and the other don't do anything, how do you the manual programation, i tried it but it the same issue, hope you can help me

Hi Guys - sorry to bump an old thread but there is a bit of a gap here for anyone else that wants to do this. I've been tasked with adding these buttons to a 2010 Nismo edition. I've found the part # for the buttons, it's : 25550-9N00B and if you do a google search, a plethora of vendors will show it for about $55.

What I'm curious about is how easy is it to swap in? The user CJeazy above makes it sound like it's a simple snap-in, but I know from experience (350z) to swap these buttons I had to remove the airbag with a torx wrench, remove the steering wheel, then swap out the buttons. Even then, the wiring wasn't in place.

Has anyone else done this with a bit more info? Are the wires there and run all the way to the trunk? My intent is to connect it to the Axxes system for an aftermarket unit to control phone calls.

Any information is much appreciated, or if you at least can find an existing topic, I've done countless searches.

You should be able to find what you need in the Factory Service Manual. See link in my sig.

Edit: This is a great site but the search feature sucks (or maybe I just can't figure out how to use it effectively). I prefer going to Google and adding "site:the370z.com " to the front of my search string.

Thanks - that will help me research how to add the controls for sure.

It would be nice if someone that's actually done this could chime in to save me hours of reading - i.e. if the harness cable exists or not between the front the the rear of the car, etc.

Thanks again.

It's not adding the buttons to the steering wheel that is the hard part, because those buttons go into the bose system in the trunk they run through some kind of harness that mutes the bose system and answers the phone. I do not see this as an easy task at all. Of course if we had the diagrams it might be easier to figure out

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.
