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.
Where can i buy new canbus gor ownice c500? I send mail to manufacturer but no answer

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
I'm hoping you can help, I don't have much hair left to pull out!
I have an Audi TT 2003 and bought a VW Passat android 4.4 head unit.
The head unit uses canbus system to turn on
I connected the stereo to check operation and everything seemed fine.
After fitting (which took an age) discovered that stereo turns off after ten mins. I have to remove key, open and close the door then put key back in then stereo powers up again for ten mins. If I remove the key before ten mins and get out, stereo powers down.
Any ideas?

Maybe the canbus decoder from Passat it's not compatible with the Audi TT, but you can cut red wire from canbus decoder and connect directly to acc signal (12v when switch is in ACC and ON position)
All other function from canbus decoder are fine? (lights, reverse, door info, a/c info, etc)
Thanks for the reply.
There is no external canbus decoder. The canbus wires connect directly to the head unit so it must be an internal decoder.
I was thinking there may be a difference between canbus systems. They are both VAG group systems but two years different, car 2003 head unit for a 2005. Was canbus updated in this period? This is the nuclear option as it means I'll have to rip it out and start again (I have tried a canbus unit with external decoder just to see what happens-same thing just comes on for ten mins)
However, there has to be some communication as HU turns on with signal from canbus and will turn off if u remove the key (before ten mins). Also the other functions work, fuel guage etc

That's a trouble, do you open head unit to see how is inside? Maybe you can made the mod internally.
Thank you for the reply
That's what I was thinking, but I'm a little bit worried about opening it up. I don't have much experience with pcbs.
So my questions are:-
1) If I open up the canbus bypass box (from another stereo) will the pcb inside be broadly similar to the one inside the HU, giving me a rough plan as to what to look for re:- wiring and live etc
2) the switched live from a canbus bypass box 12v (as previous post said can just bypass with a switched live), is it likely to be same inside HU or will it be stepped down to 5v (should I just buy a multimeter)

1.- I have not idea, I never see inside of a unit with internal canbus decoder. You can open your unit and take some pictures maybe I can help you, also take pictures of the main harness of your unit.
2.- For a external canbus units just cut red wire from canbus decoder to head unit and connect the red wire from the side of head unit to 12v switched.
I will post some pics
And thanks again for the help
Hello,
I am using an android head unit (px30) in a ford Mondeo mk4. Suddenly the screen did not power on and found that the canbus stopped working. I need to buy a replacement one, but I need to ensure that will work in the specific model. I 've tried to ask sellers in aliexpress (dasaita, isudar, etc) but they can't confirm that will work. Should I take the risk and buy one? Is there a way to check and pick the correct one? (Mondeo does not have ACC connection pin to power on red wire coming from iso cable through the harness, it needs canbus and CANL+CANH will tell the unit when to power or not, so i had to modify and connect both red-ACC with yellow-Power cables together but now I have to shut down the unit on my own). So Is there a way to find the correct canbus for ford or does not matter which one to buy and confirm only the car model?
Thanks and Regards,
Tasos
I take it you didn't buy your HU from Aliexpress or you could just ask your original seller to sell you a new one. In theory any Mondeo MK4 CANbus box should work if all you need is to control power and illumination as those are separate wires coming out of the CANbus box. You might get compatibility issues if the new box doesn't translate all the bus messages your HU needs for other features like temperature, open doors...
I would suggest you start by opening the broken box and re-solder all the connector pins and any other pins of roughly the same size you see.
So i recently ordered a Teyes CC3 for my 2015 Honda Civic SI. I was told before that it would work on my car because it has premium audio and the connectors are different. They told someone else it would work plug and play and they sent him a 201t CRV harness and it turns out it didn't work. So Teyes agreed to send me some extra stuff for free with my purchase of the head unit and in return i would help them figure it out. I have background knowledge as I am an automotive technician by trade. However, a lot is lost in translation from Chinese to English.
So i haven't gotten my unit yet but the other guy that bought it first said his powered on but didn't have sound. Well that's probably an easy fix as he didn't power the amp. The bigger issue is that he said the reverse camera, side view camera, and the information display did not work. So i was able to find the manufacturer website for the canbus decoder and also Teyes sent me a PDF file that says how to wire it up. The issue is that the manufacturer of the decoder translated some of the definitions into something else and the wiring for the CRV do not completely match the wiring for my car. They have some pins listed and on my car it shows as not used. Anyone here have experience with wiring these things?
The ones i am most confused about are labled BUS+, and BUS-. I believe these go to the information display and might transmit information such as time and audio information. These are not the can network as there is a CAN_H, AND CAN_L pins. There is also SWC_A, B, and C. I believe these are for steering wheel control. BRAKE_OUT and REVERSE_OUT i believe are outputs to signal the head unit the car is in reverse to activate the reverse camera screen and to notify the unit the handbrake is off.
nit the ones i am completely lost with are labeled RXD, TXD, B_CTL IN, RCAM_CTL IN, and A_CTL.
aMy idea what these last ones might mean? Maybe A_CTL = AMP CONTROL. RCAM_CTL IN= INPUT FOR REVERSE SIGNAL???
Just bought one of these eonon q03pro units to put in my 2006 mercedes c180 (W203), its a universal unit not car specific, to replace a failed other chinese unit(8 core 8667 chip based unit). I have tested it today but not fully fitted as waiting for facsia kit to arrive.
My last unit was car specific with dedicated wiring harness and canbus for steering controls, this one only came with a standard ISO connector and I have a dedicated mercedes wiring harness coming with the facsia kit, however having a day off I decided to try powering up with the harness from the old 8667 unit, it powered up ok but the steering controls will not work. I have been told Mercedes don't use the resistive control method, you can't program wheel controls like that via the key wires. You would need to use the high/low wires and select your Mercedes model in the advanced Canbus options

Hi, as you changed device , you must set also model for wheel controls via canbus settings in factory settings. It must work.
Sometimes controls must be set afterwards, depends on the canbus box (if it is SIMPLE SOFT, HIWORLD or RAISE canbus) that you installed. You have to shift between canbus settings of various car models in order to work. If you have online update for canbus controls update via internet.
Thank you will try that, maybe trial and error but I thought there would be a way to make it work, as it was from a previous unit set for W203 Mercedes c class. This is my 3rd android unit in the car so hopefully this one will work
Hello everyone, just a quick one.
If i swap current canbus with another one from different HU which worked perfectly on the same car, will i do some damage if i do so?
On new android HU i have some issues with dual AC where on previous head unit ac worked perfectly.
Thank you for answer.
Regards
Yes switching canbus to another unit will work but it ust be configured in canbus settings correctly for car model and year, otherwise steering wheel controls, doors etc. won't work.
There is a chance for instability with car system especially for RAISE canbuses

You must have same software version for car model in order to work with some other canbuses. Try with new canbus but other models of car - similar models or some other year of the car (like ie. if Peugeot 308 has mk1 and mk2 - divided by year choose each one of them and restart, see then if all works, if not try other models of same brand like ie. Paugeot 307 408 406 etc.) , something must work. It helped me find right canbus software after installment of new multimedia.
