I bought a unit recently identified as Android 8802 https://www.ebay.com/itm/7-2-Din-Qu...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2648 . It only has a Key 1 wire. My car, '03 Volvo XC70, has 2 CANBUS wires in the harness, CanL, CanH. I did some reading and found that sometimes you can ground 1 of the wires and just use the other. I tried this both ways, ground L and connect H to Key 1 and, ground H and connect L to Key 1.
One of those combinations was BAD, no lights on dash and major oh sh!# moment. One of the combinations let me set the buttons for vol up/down and track forward/back BUT, after setting the last button and exiting the setup software whatever was the last function I setup would act like I was pressing the button continuously. Like if it was vol up it would just keep going up, up, up, up, up etc.
Has anyone else dealt with a HU that just had Key 1 and 2 BUS lines?
I think you would want/need a canbus adapter. I found this: https://volvoforums.com/forum/audio...ermarket-steering-wheel-radio-controls-57081/
Thanks for the link/info. I'm seeing a lot of "if" and "maybe" and the like. Nothing that is identified as The solution. I'd much rather try to understand how my unit, which has only 1 SWC wire (Key 1) is meant to be connected to cars to make it work.
I was thinking about joining both CanL and CanH to the Key 1 wire. I'm no EE but my assumption is that if they are both putting out variable voltages and resistances (one "low" and one "high") that combining them would just be sending the entire range of signals through the Key 1 wire to my HU for decoding by the on board s/w. Anyone see a red flag on that?

Generally canbus is sending out a digital signal. Headunits are expecting an analogue voltage or resistance between key1 and ground. A key2 wire just allows a second analogue signal to be used in addition (I use a key1 +ground and key2+ground in our mazda5 as it has *resistive* steering wheel controls with two different paths - one for most controls and one for just the "phone" button which in the oem set-up only routes to the bluetooth box). I am surprised that canbus signals on their own can ever function on a headnit that is expecting resistive/analogue voltage inputs. I would never attempt to hook it up, but instead would source a canbus adapter that will convert the digital signal to an analogue output. This is exactly what I have on our Saab 9-3: canbus to Connects2 adapter to chinese head unit, where the connects2 box output is connected to the headunit key1 and ground. It is to note that some chinese headunits come with a canbus box built-in, but for a specific vehicle, and in that case the canbus wires would be hooked up directly.
Ahh. That is a huge distinction that I had not heard anywhere else. The fact that the CanBus is digital and the HU is analog. Had you not stated that you also have a Chinese HU (assuming Android) I would have thought you were referring a traditional HU. Why is the Android unit not designed for the digital signal?
Are you certain about all of this? Is this a true statement, "The Chinese Android HU's are designed only to connect to SWC that are analog, NOT the digital CanBus lines"?

As I stated above vehicle specific Chinese Android headunits will come with a canbus adapter (if required). All universal head units that I have seen (meaning Android Chinese head units) are expecting analog inputs. If you look at the advertising for joying or others on aliexpress it explicitly states that you need a canbus adpater if your vehicle outputs (in the harness for the radio) canbus signals. Be aware that the canbus signals that transmit steering wheel control information are not standard, each vehicle manufacturer is free to use whatever signal chain they want for the controls as they are also the "supplier" of the radio. That is why they have vehicle specific canbus adpaters (where the aftermarket canbus adpater manufacturer has "sniffed" that vehicles canbus lines to learn the codes), or universal ones that either learn thru button presses and/or are coded with multiple vehicles. I advise you to contact axxess (if you are in N/A) or connects2 (if you are in the EU) and talk to them about what you need. I have been in contact with both those companies over the years and both should be quite helpful. PAC is another option, but I have no experience with them.
---edit---
All that being said I did a little more googling on your vehicle and it seems it is a problematic one - connects2 shows using the axxess adapter, but only for later years than yours and axxess states that they have no info on your model year. All the more reason to contact axxess, but in the link in my first response didn't someone get your it working with your vehicle and year?
---more edit---
Reading thru that linked page it is definitely a problematic vehicle - it seems like this may be your best bet but more research is definitely required: https://www.crutchfield.com/p_249SWRVL54/CRUX-SWRVL-54-Wiring-Interface.html
Great info. Thanks for your time and your advice.

Hello All
I bought a new Android Stereo Unit : can not show because i'm new member
SWC does not worked when I connected The Unit to the Car as seller told me . Key1 and ground wires from Stereo to SWC and ground wire in the car. Couldn't select any key on SWC screen in Android.
So I did several tests.
1 – first I tested Output Voltage on Key1 wire comes from Stereo . it 3.6V
2 – I tested Voltage on SWC wire comes from Car . it 12.2V
3 – I connected my SWI-JACK ( I used for my previous Kenwood double Din). I tested output voltage and it less than 1V
4 – So I tested voltage on SWC wire comes from car but before it connected to SWI-JACK and it was 3.6V and less ( depends on SWC button I pressed)
So I connected SWC ground wire from Stereo to the car ground and key1 SWC wire from stereo to SWC wire from car between Car and SWI-Jack.
Now I'm able to select the buttons , but I can save only one of it , for example Volume + and when I'm using it – it stacks and increase the volume till MAX .
Does someone know that’s wrong with it and that to do ?
Thanks a lot

1. What car?
2. Do you have a resistive or Can-bus SWC system in your car?
Normally on Hyundai/KIA (Resistive type) Key 1 is connected to the car system.
Key 2 left open and SWC ground to car ground.

Try to use the same Pacbox Can-bus to resistive and use Key1 and ground. Or get the correct Can-bus box from the manufacturer.
You also need the correct loom for the Can-bus from the HU manufacturer.

Thanks. i tried work with my can-bus . the output signal is less than 0.5V , so probably that is the reason the signal does not reach the unit.
The manufacturer say that i dont need can-bus with this unit.........

Since you mentioned a voltage change when you press a button on SWC to me it sounds like resistive.
Because that's the way it works. To test your HU for correct function, connect something like 500-1000 ohm
between Key1 and SWC-ground. Tap volume up while you are in the SWC panel, don't forget to save the button when finished.
Connect one end of the resistor briefly to Key1 while the other end is still connected to SWC-ground several times and your volume should increase.
If it does, your HU is okay.

Android china hikity Is250 swc
I have managed to install a 2nd gen IS250 steering wheel into my Aristo aka 2nd gen GS300.
The paddle shifter and cruise work but I woukf like to use the steering wheel controls for head unit and phone from the IS Steering wheel.
I am running an Android deck. It needs only two wires to feed the volume* mode and tuning functions.
It seems that the input to the deck uses a different voltage for each function.* This seems to be dine by using a circuit board known as a resistor ladder. So each switch gives a different resistance when pressed.
I am assuming that one of the deck s 2 SWC wires is an output voltage and when a switch is pressed, a voltage based on the resistance for that switch, sends a particular voltage to the second deck SWC wire.
I would like to see the wiring diagram for an IS250 with SWC for phone and deck.
If I am wrong in my understanding i would be happy to be corrected.
The Android deck has a learn function for each button so it seems to make sense.
There is a pIc of the audio control part of the SWC. I am trying to do this without canbus or axess or pac as they seem unecessary due to the Android deck learning in the set up.
Hi,
I finally bought this universal SWC unit from aliexpress: https://nl.aliexpress.com/item/Car-...574.html?spm=a2g0s.9042311.0.0.2f4f4c4d3Pq2pc
I repeated this Boyka video, so I'm pretty sure that I did everything correct.
My unit originally has a CANbus as I have a Skoda.
I removed the CANbus when I got the unit (because I don't want it anyway) , connected it again 2 months ago (let's give it a shot), and now for the SWC I removed it again (as I know the CANbus "takes over" when it comes to SWC).
I disconnected the brown key1, the pink key2 and the GND wire from the little CANbus adapter connector.
From the the SQC receiving box to the Joying, I connected ACC to ACC, key1 to brown, key2 to pink, GND to GND.
In the steering wheel screen nothing works when I push buttons on the small unit or on the screen, be it long or short. The 6 fields in the top of the screen only quickly alternate between 254-255 (see attached IMG_20181020_145152172.jpg).
So then I connected my multimeter (set on 20V) as well. I connected the RED additionally to the key1 and the BLACK additionally to the GND.
I now read 5.3V source voltage. When I push buttons to close the loop, the voltage drops for a number of keys to, for example, 0.8V or 1.3V or 2.8V. Some buttons don't react.
When I connect the RED additionally to the key2, the source voltage is again 5.3V. Now the other keys show values like 1.3V or 2.8V when pressed.
Obviously the little universal unit works and it obviously needs both key1 and key2 wires.
As said, I have the CANbus disconnected and in the CARsettings I have set the CANbus settings to NULL.
What is wrong, or what am I doing wrong?
(Note: I repeated this on my Sofia unit with the exact same results: zero, that is).

I bought one of these for my Joying Sofia system, one made for VWs, as I have a Passat. I had the exact same experience as you, right down to measuring the voltages and seeing them change.
Step back to my previous sysyem, an Xtrons that I bought a universal steering wheel mounted wireless controller, and it worked flawlessly. The Xtrons was also made specifically fow VWs, but the generic controller worked fine. I tried it with the VW-centric Joying Sofia and went through the testing discussed previously.
I contacted Joying Support and was told that the system itself would only respond to the resistance from the VW Can Bus and unless I had that I was out if luck.

Thanks for your reply.
Did Joying say anything about when you remove the CAN bus adapter? Should it somehow work in that case? Because I first disconnected the brown/pink from the Joying CANbus connector and also removed the entire JY CANbus itself.
Anyway, I will check again. I thought that the brown and pink key1 and key2 wires were leading, but obviously that's not true.
The green (CAN/L) and black/green(CAN/H) wire coming from the Skoda (in my case) ISO adapter are leading into the JY CAN bus. The pink/brown then come again from the JY CANbus and lead to the unit.
So I will try to connect the key1/key2 wires to the green and black/green wire. But maybe I need to ground the CAN/L wire and connect one or both key1/key2 wires to the CAN/H wire.
(Although in one of the Joying diagrams, the green and green/black are for the Left Rear speaker, but that does not comply with my Skoda ISO adapter. confusing.)
Of course it can also mean that the JY CANbus expects a digital CANbus signal instead of an analog resistive signal, in which case it will not work at all, not without an analog to digital converter at least.
To be continued.

The way they made it sound, the stereo itself only responded to CAN bus signals. The reply was a little strange in that it mentioned 'resistor values that match original VW'. I don't know if other head units have this problem, but am a little frustrated that I lost this functionality that I had with a "cheaper" Chinese head unit.

It is also very weird.
I checked the Boyka video (https://www.youtube.com/watch?v=odnEb-1b310) where he is in a VW, using a Joying unit with a CAN bus where he simply soldered/connected the key1/key2 wires to the brown and pink. Why does that work? It is a Sofia like you have and like I still have on the bench currently doing my tests on.

I had some more mail exchange with Joying. The VW models have a different motherboard with different connections. The unit in the video is actually a universal model just connected to display the working of a universal SWC with a universal Joying unit.
So maybe I should try to use some "universal analog/CAN-bus steering wheel converter" and connect the SWC to the converter, and then connect the converter to the CAN/H, CAN/L connectors of the Joying ISO adapter.
But I'm already tired of it. I wanted a simple way to try and maybe do some test work for XFytTweaker.
Hello all!
I've got a Joying Octo-core 4Gb/32Gb 8.1 SC9853i unit installed in my 2005 Toyota Prius (w/nav and jbl sound.). I'm very pleased with the main functions of the unit, but I'm having a couple of issues. I've been messaging Joying about it. They're trying to help, but I'm getting the impression they aren't quite tracking me.
The first issue is with the steering wheel controls. My car has the three wire controls which are attached to key1, key2, and ground on the Joying supplied Toyota harness. I have double, triple, and quadruple checked these wires on both sides of each connector. Using my multi-meter, I can see changes in resistance upon button presses when checking from key1 to ground, and different buttons from key2 to ground, exactly as expected. I can see this happening all the way to the iso plug that goes to the back of the head unit. The signal is definitely getting to the unit.
When I go into the control software, though, absolutely nothing happens when I try to program buttons. There is a batch of numbers across the top that are supposed to change according to resistance, but they are quite stubbornly sitting at 255.
If my phone was exhibiting squirrelly behavior like this, I'd re-flash it and start fresh. Extending this concept to the head unit, I found Joying's update page and pulled a fresh copy of the firmware, carefully checking the version for my head unit. This one is the 4.3 release. It appeared to flash successfully, but there was no change in the SWC functions. I also tried the 3.29 release to no avail. I ended up sticking with that one for now, as notifications don't work on the newer release. I also rooted it with Magisk. That didn't change anything, not did I expect it to.
I'm also having difficulty with my reverse camera. My car did not have one to start with, but I added one a very long time ago using a CanView system (a low-production aftermarket mini computer that injected video via the navigation feed.) I've removed all of that except the camera itself, which is a simple thing that produces video on a composite RCA plug, which I've plugged in to the rev-video jack on the head unit. It completely refuses to switch to the reverse video.
My harness has a can-bus decoder which I thought would pick up reverse, but I'm starting to think it only enables the jbl amplifier. So, I grabbed a reverse wire from the tail light and connected it to the appropriate wire in the harness. It still won't switch. I even tried using an always-hot to test the reverse and it wouldn't switch. I repeated this with a completely different RCA camera, just in case the problem was with the installed one. No dice.
I'm at a loss for what to do to troubleshoot now. Anybody have an idea?
cannot say anything about SWC as i have different HU.
About reverse camera - can you post the picture of your harness? Usually HU has the wire marked as "BACK CAM" or "REV CAM" or "REAR CAM" or similar, and the +Vcc (or GND) on this cable controls the switching to reverse camera view. Some HUs have switchable setting to detect either +Vcc or GND on this cable - pls check this also (it is in the car settings in a part protected with password).
Hello fellow Prius NHW20 owner! I have just installed a SC9853i based Android 8.1 unit (can't post link yet, search for Nuoweida 9853 solution). My steering wheel control works fine. I connected a 68 Ohm resister between pins 9 and 10 of the CN703 port. I connected SW1 (pin 7) and SW2 (pin 8) and GND (pin 6) to the corresponding wires of the head unit. I used the Toyota Steering Wheel harness that I got from ebay.
I still haven't installed the rear camera. Let me know if you have any questions.
Hi all,
I have the Joying Android Oreo JY-FO128N4PX5S installed in my Ford Focus ST and have issues which Joying have not been able to fix.
The main issue is that something in the head unit is keeping my ECU alive so the Dash led where the odometer is stays on 24/7
I disconnected the Canbus and it seems to have fixed it for awhile but now I have not wheel controls.
I reconnected the Canbus but cut the black/red wire and spliced it into Key2 wire as recommended by Joying. And tried to re-learn the wheel controls but this does not work as the controls do nothing in this setup.
But ECU stays on. Anyone know if there are any settings inside the unit to make sure it goes off when the power is turned off and does not keep sending messages to the ECU.
Thanks
Most units with CAN bus SWC controls have a different motherboard than units with resistance based SWC controls.
Probably your unit must use the CAN bus otherwise your SWC will most probably not work. That his for the FYT units. Your PX5S is an STT unit. That might work differently.
However, in your case you probably have 2 constant power leads. Both the red and yellow power cable deliver constant power. That is why your unit stays on.
In some of the VAG (VW/Skoda/Seat) cars it also works that way: Switching off the builtin radio is also controlled by the CAN bus and this CAN bus stays on (but not the radio in that case). All those Chinese "multi purpose" units do not support that.
Please check if both power cables deliver constant power.
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:
https://axxessinterfaces.com/products?Year=2008&Make=Nissan&Model=350Z&TrimOption[]=Base%20audio&TrimOption[]=BOSE&TrimOption[]=Standard%20Audio
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.

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.
