About CANBUS box - Android Head-Units

Hello,
I would like to understand more about the canbus box, hope someone could share some knowledge.
I see the models for sell and is like, model 1 is for 3 cars of the Y brand, other is model 2 is for 10 cars for brand X brand and so on... And if i check for example RZN vs HiWorld is almost the same car list.
I think the data the canbus have is not specific to the type of car, but for the can version of the car correct?
So, if a box have information for the Sylphy and for the Tiida, i can select any of these in the car select of the car?
I ask this because i have a sentra/sylphy, my box is Raise and my unit have sylphy only on the hiworld box, i use X-Trail in Raise and i have the basic working fine, dash TFT with radio infos, clock etc... But the new unit that i don´t install yet, don´t have sylphy/sentra in any place (i already ask a update for the vendor).
Another question related but not so much, these boxes make the 6v for the backup camera too? My current box use a exterior 12v - 6v converter, but the new one don´t have any of these, only the box.
Thanks for all the replies!

I have seen both types, one where the 6V came out of the Canbus decoder directly to the camera and another Canbus decoder from the same maker where that same wire went into a 12V/6V converter before feeding the camera. Suggest you probe the camera voltage feed wire before trying to connect the camera, I did on the first Canbus decoder and found 6V.

Indeed, after i read your message i check the Upindo vendor in aliexpress, he share the pins layout, and i compare some boxes there, not only some have 6v output but some have 16pins and others 20pins.

Jy-UL128N2 - Wiring of canbus decoder box

Hi all!
I have just installed a Joying JUL128N2 in my 2007 Alfa Romeo 159.
Overall, I am happy with this unit.
I have read through most of the posts regarding this unit, and that has helped me to solve a lot of issues in the last 3 days. For that, I thank this community!
Anyway, I still haven´t hook up the canbus box to enable my steering wheel controls. I have the following question:
Installation
I have purchased an ISO wiring adapter kit for my car (CTSAR002.2), which includes a canbus decoder box connected inline, (by a plug in one end of the box) between the car side of the wiring and the headunit side. It seems that wires go in and out from this same plug (at least 3 come out and are free)
There is another plug in the opposite end of the box that should be used to connect to specific radio brands. I received a universal version of that cable (CTMULTILEAD.2), which has 3 wires and a 3.5mm jack plug.
Question: Do I need to use the “multilead” patch, or should I use the 3 free wires coming from the front part on the main harness?
In any case, what goes where?
The mentioned cables for reference:
http://www.connects2.co.uk/Product/ProductItem/CTSAR002.2
http://www.connects2.co.uk/Product/ProductItem/CTMULTILEAD.2
Furthermore: is it possible for other car brands, other than VAG group, to send more information to the HU, such as parking assist and other car info?
Thanks very much!

CANbus decoders - who is manufacturer...?

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?

How to get a Canbus Decoder box replacement - Ford Mondeo Mk4

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.

Help with wiring definitions canbus

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???

Android TPMS How does it work

Hello. guys
i got hold of a TPMS kit from Teyes. 4 tpms in tyre sensors, and usb reciver device with usb. i also got the Teyes cc2plus head unit.
My problem is that i have to sets of tyres. Winter/summer. So teyes or other brands that supports android 10. only ship with one set of 4 sensors.
I Have a Autel MaxiTPMS TS508 unit. I tried to read the sensor but faild to read. As i know the sensor is on 433mhz. and like other china products no markings or numbers.
I would think it was a easy job to just read the sensor and wright to a new one. so then you would have 2 duplicate sets. but no.
I am hoping some of you have the knowledge to help me.

What about the teyes thread that discusses your unit. You have to put some effort in on xda, there are no guys
First contact for support is Teyes, what did they suggest you do before returning defective product
I'd like to read my factory(!) TPMS sensors with my android head unit. Since OBD2 dongles don't seem to provide TPMS data (shame...), I think buying an aftermarket TPMS set, solely for the USB receiver unit. Since I can read TPMS data using my RTL-SDR dongle from my PC with no problem, it may be working, just a question of configuration.
And yes, "question of configuration". Did anyone around here have experiments / experience with such an USB receiver unit? Or am I just overcomplicating things?
@hurjup
Check the CAN settings in your unit. The OEM TPMS data are provided via CAN.
Depends on the car if the CAN box is able to translate these data to be able to see that in your radio.

Could you explain a bit "can box"?
For the very same(?) head units sometimes an additional box (can box?) was provided and sometimes not. Amyway, I didn't receive anything like that for my suzuki s-cross, which looks normal to me. Is it embedded into the unit (which doesn't implement TPMS reading)? Or is it not needed for general functionality?
In short, knowing my car type, can I improve the situation with TPMS, or it is better just let it go?
Thank you in advance...
Well...
I don´t know if your unit has an internal CAN-Box or not. Please ask your reseller.
Nevertheless:
Even your suzuki s-cross should provide these data via CAN.
So possible issues could be:
No CAN-box internal or external (but I expect to get clamp 15, Reverse gear and some other stuff to be provided by any can box)
CAN settings in the unit are wrong
Wrong car set
wrong CAN box set
But most of the time you run into the issue that the CAN box (internal or external) does not translate these data. (most of the cars are not supported for data more than SW-Buttons, Clamp 15, Reverse gear, e-brake)
You should contact your reseller and ask if there is a CAN Adapter available which decodes these data for your car.
I searched already, but did not find any for your car which should be able to do what you want.
I vote for the "CAN box does not translate these data" option. I've contacted my seller, but expect multiple rounds when it tries to google translate "can type" or "can adapter" before hitting a dead end. I don't expect any resolution of this problem through support, simply because the product page wanted to sell me an aftermarket TPMS set for my particular car type.
Some time possibly I'll make a try with such a set, maybe an app dev was lazy enough to adapt rtl_433 with minimal modifications and it will just work.
You´re not allone...
For my Mitsubishi I even don´t get the door open messages and climate control through the CAN box.
Even intire OEM TPMS is not visible. Just visible in the cluster. It is available on CAN, but not translated.
If you would own a VW Golf as example, you would get all this stuff on your unit....so guess why no one get´s on the CAN traces and translates the signals for cars which are not sold that often...
