Seeing if anyone has any input here to possibly assist getting on of the new Joying Android 10 units working with the steering wheel controls on my 2008 350Z. I just cannot wrap my head around this. I don't believe my car has CANBUS but there seems to be no real concrete info. If not, I've read some conflicting items here. There's 2 plugs on the car harness that went to the stock radio that don't seem to have an equivalent to the aftermarket harness or unit. Can they be adapted somehow

There are universal adapters but I read that you have to splice and solder IN THE CAR for this **** to actually work? What a nightmare. Is there anything that I can pre-wire that just works? The AXXESS and PAC unit seem to require an engineering degree to figure out in addition to splicing the factory harness. This all seems so ridiculously difficult, there has to be a better way here.

What is your unit, post info including MCU, joying means zip.

Yes, please post additional information. It looks like there should be an AXXESS module for your steering wheel controls. You have to indicate which trim option you have...base audio, standard audio or Bose. Here:


You can update the trim on that page to be specific to your car. I took a quick look at the instructions and CAN-HI and CAN-LO so it looks like it's possible yours has a Canbus interface. If yours does, not sure if the AXXESS modules will help. If you don't need a canbus module for anything else, then you could possibly use the AXXESS module just for the steering wheel controls on the canbus interface.

I used an AXXESS module for my 2012 Kia Sorento as the amplifier and sound required it. It came with a steering wheel control module as well. Took a bit, but finally set it up as needed. The best thing you can get is a schematic for your car as it will show details about your steering wheel buttons and how they communicate / are wired to the head unit. Get the schematic and you can set up the buttons. Mine, however, does not have or require canbus.

Thanks for the info, but this is nearly impossible for me to understand. The tech docs for this AXXESS make zero sense at all. I don't see any of the items pointed out in the documents on my harness for either the car or the radio. They simply do not exist. I don't get how there are zero plug and play options for this. I don't see any options for Canbus for my car either. Whenever I Google this, I only find info related to LS1 swaps (meaning those who put an older Corvette motor into their 350Z). So frustrating.

Well, let's start with a couple of questions:
  • Sounds like you've already installed the head unit...correct?
  • What is the Joying model number?
  • Do you have schematics for your car? If not, can you get them? These will definitively inform what wires to use. With the buttons on your steering wheel, like volume up and down, they went to your factory head unit to change the volume. This information either went directly to the factory head unit for it to interpret or went through the canbus where the factory radio also obtained this information
  • Did the harness you used have a can bus module? It's a small box with a lot of wires going in and out.
Whether or not you used or need a canbus module is another question. What kinds of other things did your old factory head unit do:
  • Did you have bluetooth phone built-in?
  • Rear view factory camera?
  • Rear factory radar?
If your factory head unit was fairly basic, then you may not need a canbus module. Please post a picture of your dash...maybe a couple with the gauges and another for the center stalk where the radio and the climate controls go...also a picture of the steering wheel buttons. These will help inform the likeliness of having or needing a canbus module.

Not sure if you know what a canbus module looks like. This page shows 5 different types/manufacturers of canbus modules:


If you don't need a canbus module, you need to figure out which wires to use to connect to the Android head unit.

Thanks for your continued responses and help mastrv. I'll answer your questions as best I can:

Sounds like you've already installed the head unit - Yes. I had an older Joying unit since 2016. The same harness can be used so it was a simple swap out after the not-so-simple task of pulling the entire center console away from the car.

What is the Joying model number? - I don't see this anywhere at all. Not in About Device, not in other menus, not on the box, not on the unit, not on the Amazon order, not on the Amazon product page. I cannot find this info whatsoever, and I have looked for it thoroughly.

Do you have the schematics for your car? If not, can you get them? No, and maybe at best. I don't know what I'm looking for here. There are two plugs that went to the factory CD player that go unused on the aftermarket harness. It's absolutely mindboggling there isn't an adapter for this.

Did the harness you used have a can bus module? I don't know, but I don't see anything resembling this in my car.

Did you have bluetooth phone built-in? Nope.

Rear view factory camera? Nope.

Rear factory radar? Nope.

As for the rest, I'll need to do so over the weekend. The entire cernter console has to be removed in this car to replace the head unit. This is why it's absolutely not possible for me to do things like solder inside the vehicle, and majority of these items are tucked away. How does AXXESS or PAC expect users to install this garbage? There isn't any space for it, and they label wiring that doesn't even exist in this car! Why not just made a single adapter and be done with it?

From the information you've provided, it's most likely that you don't need a canbus at all...especially since your old unit didn't have one.

The only thing you're concerned about is the steering wheel controls, right?

Only thing that needs to be determined is which wires to be used for the steering wheel controls.

OK. I think I've found some good info for your model. The info doesn't have 2008 but it's for a 2007 and I think the 2008 is the same. This has information about the wires to use from the factory harness that connected to the old stereo:


It's for something called a Radio Button Box for racing applications. The install details the wires to use. On pages 2 and 3 it shows a piece of a schematic and identifies wires for Remote Control A, Remote Control B and Remote Control Ground. These would directly attach to Key1 and Key2 on the Android Head unit and any ground. On page 3 it also talks about how to test measure with a multi-meter to make sure these are the correct wires. The wires are in M39 connector:
  • Remote Control A is pin 22 and coloured R/G, Red and Green
  • Remote Control B is pin 23 and coloured OR, Orange
  • Remote Control Ground is pin 25 Y, Yellow
There is also a picture of the connector and it shows the wires from back and front. I think it shows the connector for an Infiniti G35, which is identical to the 350Z except for the wire colours.

I think you may not need any module and can connect those directly to the Android head unit...and then use the steering wheel control app to map them as you like.

FYI, the picture of the steering wheel controls includes a rocker for Volume up/down, buttons for Mode beside a Power button and a Prev/Next rocker.

FYI, the my350z site has much information and there is an Audio/Video section:

Thanks again mastvr! Still really confused on this. So, my harness to the Joying unit has a pink Key 1 and brown Key 2 wires. What I don't get here is how I'm connecting to the car here. Soldering is pretty much off the table. I'm also very leary of cutting anything factory in the vehicle, although I guess if I HAVE to, maybe I would. My apprehension here is that if I cut something, and it's wrong, I'm going to end up with a hacked up factory harness that I neither have the skills, space, equipment or otherwise know-how to fix. That's why I sincerely wish there was something I could just adapt in a plug-and-play fashion. So completely frustrated with this.

If you don't have a connector for the plug in the link I provided, you can always use a t-tap connector so you don't have to cut it...or maybe there's some module you can use.

Anyway, there's enough info to make sure those are the correct wires. So, good luck with the rest.
