Most of the Android ChinaRadios come with some sort of CANbus decoder (or so they are labeled) to provide steering wheel controls, backup support, etc... Every single vendor will only sell you a CANbus decoder that they 'manufacture' for their units - claiming that any other combination of decoder/radio will not work.
Aside from this being mostly BS, these vendors are absolutely adamant of not wanting to sell individual of these decoders - which for Chinese vendors is curious, to say the least, to turn down any opportunity to make a buck.
Either way, despite all of them claiming to manufacture their own, we know that is BS -- these vendors buy products from actual manufacturers, repackage them, and sell them.
Try as I might (Alibaba, aliexpress, globalSources) I have not been able to find a manufacturer that produces just these boxes.
Does anyone around here have any leads?

To add more to that.
My previous unit an Witson 3066/1Gb ram has an CAN decoder that worked fine for my Ford but the Joying ones work only 85% fine meaning the PREV and NEXT buttons were reversed and that was a pain to use since all my life when I push the NEXT button I expect to hear the next song not the previous one.
Anyway, although I was struggling to correct the Joying CAN mistake I could not because I did not find any way that I could reflash the CAN box. Joying said that the CAN might not be 100% compatible with my car although it should be.
Even if the old CAN box from my former Witson unit was looking exactly the same and the wire socket was exactly the same as the Joying one, the wiring was completely different, different wiring location on the socket, different wire colours. The internals of the CAN boxes looked almost the same but I did not had the courage to test the Witson one on the Joying afraid that I would damage the headunit or more importantly the car...
What I did in the end was to directly connect the resistive buttons of the steering wheel directly to the unit (bypassing the CAN) and program them via the unit software and let the CAN box to decode the other stuff like putting the car in reverse, turning on the lights, feeding +12V to the unit when I start the car.
What I learned is that CAN box is a black box... if it's not working it's almost impossible to find a fix of any kind... or buy a working replacement...
That appears to mirror my initial impression, albeit I feel that different vendors use different providers for these CANboxes and hence that a different CANbox should be able to do the job another can't.
Example, on my XTRONS unit, the steering wheel controls didn't work at all - albeit reverse detection and lights worked well. Unlike my prior box (from 'alec-power' where everything worked (except the radio didn't produce any sound - a slight issue. They took it back and refunded me). Now, XTRONS had me send back the CANbus box, and promised to send another as soon as they have stock again. (1-2 weeks), but they also confirmed that their e39/e46 (BMW) decoder is the same as the one for e53.
What we really need is to figure out how these CANbus boxes work, and ideally how to program them (if that is possible -- which it ought to be).
That's what I was attempting to kick-start with this thread.
Bummer, so no one has any information on these CANbus decoders?

Your best bet is to try a different car in the canbus setting in factory settings. I had that problem on my ford focus I set the canbus for it and it didn't work right with the steering wheel so went through them all to find that the ford Mondeo rise settings worked and fixed that problem for me.

Turned out, in my case, that the proper setting was "NONE" in the CANbus settings, and suddenly everything worked.
Chinese engineering....
If you need a canbus box, your best bet would be to go with a more mainstream manufacturer, like axxess/metra. Their units can tie back into the car radio using the SWI1/2 wires.
Any update on this?
Just reviving an old thread looking for answers
I also think there is a problem with my bmw e39 can-bus box i am using with Xtrons PQ7939BIP. When i connect the can-bus box, the red (terminal R) and the yellow (battery + terminal 30) become "shorted" and they should not "touch" each other. This way, i have to connect the yellow and the red wires from the android unit to the violet/white wire from my car (terminal R - accesory) and leave the terminal 30 (hot all time) wire from the car disconnected so that the xtrons unit shuts down when i put the ignition switch in position 0 or when i pull out the key from the ignition switch.
Is this normal or is my can-bus box bad?

You can connect the red wire to any wire on your bmw that has 12 volts with the key on RUN or ACCESSORY, but the yellow wire needs to have 12 volts all the time.

Every PX5 and PX head unit can work with a canbus decoder from different manufacturers. You have to go to Android Settings > Car settings > Factory settings (password: 126) > Canbus tab > Select the manufacturer of your canbus decoder and the car model.
I have a PX5 head unit with a canbus decoder from "Simple", and when it broke, I replaced it with "Raise" and it works.
I recommend to review the list of supported canbus decoders in your head unit in the Factory settings, before purchasing a new one. You may need also to buy a new wire harness if you don't have a plug for the canbus decoder.

Hi,
I also have PX unit (PX6) with Simple soft CANBUS and I get more options when I chose raise like air-conditioning info on my PX6 unit. I have Honda civic 2016 and the only thing that is not working is the car clock not syncing through the CANBUS from my Dasaita PX6 unit. which is a bummer.
I am very curious about the Can Box options as when looking to buy a unit for my '18 WRX with HK Audio I found the IDoing selling them with support for the HK and was surprised as Crutchfield and Meastro just added support for this setup and I was about to order their harness and box to wire in a Kenwood unit I have in my old car.
When I found the IDoing(FYT) I figured all the other better know sellers should have had same option so I emailed Joying as I couldn't find option from them and they responded that they didn't have a solution. SYGAV does claim to have one but but it's nearly double cost and all the WRX reviews said it was hit or miss if it worked.
I bought the IDoing unit and it was plug and play and works great(with one exception)
If these are all the same HU and CanBus hardware, why the variances? Just programming by the seller or are they all buying from different MFR?
Before ordering I tried to order a harness and canbus from IDoing and the unit from Joying, Joying wouldn't sell me the HU because I had mentioned I had HK Audio and IDoing Flat out refused to sell me a canbus and harness without proof I had bought a HU from them.
That said the Unit works very well and the only issue with the Canbus is that it can't control the rear speaker separate from the front(no fade).
Someone earlier mentioned buying a maestro, has anyone ever connected one of these chinese units to a maestro box?
Just so everyone knows
I managed to add canbus functionality to my xtrons unit even though they said it’s not compatible
I bought a harness for my car with the correct decoder and chopped it to fit the pin outs of my head unit.
works like a dream.
If anyone needs advice I am always available
what car and what harness? You bought a canbus and harness from another "seller" and made it fit? Or you bought something aftermarket like Maestro?

Hi everyone, I’m new to this forum. I know a bit about Volvo (the older ones!), and Volvo head units, but not about Chinese Android head units.
I’m considering replacing the aging head unit of my (also aging!) 2002 Volvo V70. The head unit is a simple HU 603, so no Dolby, center speaker or extra amplifier. I’m looking at Xtrons TA702P (quad core) or TB706PL (octa core). I prefer a 7 inch touch screen, no knobs, no DVD. But navi should be good, as would radio. Music I can play through usb. And my Elephone S7 (Android 7.1) phone should mirror on the unit if possible.
Other functions like back up camera or steering wheel control are not important to me.
I know how to take the HU 603 out. I know I need an adapter harness to connect with the new unit. And a fascia adapter. All that is available.
My questions:
Xtrons has many car/model specific head units (not for Volvo). They have Canbus decoders supplied with the unit. Not so for the TA702P or the TB706PL. Will that give problems? (The answer from the ebay seller is somewhat useless: ‘Both the TB706PL and the TL702P does not come with the canbus so that you just ignore it.’) Anyone has experience with this?
How are user experiences with these modern Xtrons units? I know, ‘you get what you pay for’, I know that. But still, worth the money?
Units from Kenwood or Pioneer are other options, but again, is it worth it?
Thanks!
Hi there
I own and drive a V70 from 2006. I have replaced the original HU with a SONY 2 DIN unit (XAV-V630BT). This unit has great sound. I also swapped the speakers to JBL. It is totally worth it.
I have a CANbus to resistor unit. This makes it possible to use the steering wheel buttons.
Right now i am testing a Android HU. Unfortunately i have bought the wrong one. The unit is full of bad design choices. The sound integration in the unit is bad. I think that radio, BLUETOOTH and AUX sound runs directly to the sound processor. This means that when the Android unit plays a sound, the sound from the other units are turned off. In my opinion the other source should just fade a little.

Hi there
As said, I don't need steering wheel controls, my steering wheel doesn't even have the buttons. Must have been a cheapskate first owner!
Does this mean the Canbus only affects steering wheel control? So ignoring Canbus (no resistor as in your case), will give no problems?
And yes, by now I've found out Android units may not have the best sound quality. Or radio reception.

Hi ive recently bought a android PX3 head unit, installed it ok but it has changed my milage into KM as im in the UK i need the speedo in MPH, there is a app installed called control settings, in this there is a milage setting set to < KM > but it wont change, most of the settings in the control settings app like temp set to C wont change to F either, indicators set to one flash etc the only setting that i can change is CD indicator.
would anyone know if this could be a software bug with the MCU or the android version?
where would i look for a update? i dont even know who the manifacturer is.
The head unit has no physical buttons only a reset hole so can anyone please tell me how i would get to the recovery screen?
ive never had a android head unit before so dont know much about these units.
Can anyone please help me change/fix this setting or another app or update i can install that can change the milage back from KM to miles,

would this work with the HU, just connect upthe 3 wires? and not connect the HU plug connector that goes to my info screen?

I have the same problem, in the US with a BMW 90 android head unit. I think there is a bug in the MCU firmware that reverts back to Metric units on boot. Lucky for me, I am able to change things from Control Settings app but I do have to do it every time the unit boots. I have reported this to the seller of my head unit but they don't have any solutions. I am hoping they will fix it in the near future.
did you ever get your problem sorted as I now have the same problem
Hi no the seller didnt want to know and just fobbed me off for months before blanking me on whatsapp, no firmware updat as promised, nothing, so what i did was got a set of these:T - 3 Car Intelligent Steering Wheel GPS, hang up/answer, volume setting, music Controller with Noctilucent Function buttons https://www.aliexpress.com/item/Zee...191.html?spm=a2g0s.9042311.0.0.68734c4dUQL81J whicc work quite well, ive also recently ordered a button stalk like how the older radion buttons were: Car steering wheel button remote control lights car navigation DVD / 2 din android Bluetooth wireless Universal remote control,
https://www.aliexpress.com/item/Car...596.html?spm=a2g0s.9042311.0.0.68734c4dUQL81J but im still awaiting delivery of it.
ill be very happy with the stalk as well as the buttons ive stuck to the centre consol, no where near as cool as the steering wheel controls but i really needed my speedo in MPH
anyways hope this helps somewhat not perfect but better than the speedo flashing between KM/MPH
regards

I know this is old but I have the same issue with my Joying head unit and my BMW e90. On start up, I have to go into my settings and set everything to American/Imperial units. Did you ever find a fix to this? It's driving me nuts.
Hello, I'm writing here with a hope that somebody can diagnose the problem I have.
Recently I bought a android head unit radio that is based on joying os (it looks the same actually). I have a canbus box and I think everything is connected properly, however the swc control is not working. I checked all the canbus decoder protocols that are for my car brand in factory settings.
I managed to find an option "print protocol" which shows a can signals that gets through to radio. I can't post videos but it prints all the buttons presses and releases in hex format, but the headunit is not responding to them. Does this mean that canbus decoder is faulty? Or this mean that I'm missing something software wise?
I ask this question because I still have a dispute time on aliexpress and if this is hardware issue I might be able go get canbus box replacement.
Thanks in advance.
Hello...
Not sure if this is the correct forum for this or not so apologies.
I've just bought and installed a chinese Android Auto head unit into my Ford S Max. I think the unit is an XY Auto 3.1 8227L, nothing on the box but this is what is specced in the system info. I've purchased a Connects2 Canbus adapter to use with this so that i can retain steering controls etc.
Everything is all wired up correctly and working but I can't find Connects2 in the Canbus setup list or a Ford S Max under any of the other canbus manufacturers. Does anyone know how I can sort this out?
Other issue is that I no longer get my parking sensor beeps - does this go through the canbus as well?
Not fitted a aftermarket unit in years so no real experience with canbus setup.
Thanks
