Help me, internal canbus? - Android Head-Units

Hi, I need help
I bought an android Px5 unit, from aliexpress, specifically from the brand Cusp model HY272L, for my hyundai i20 (2018). I did not know what it was because I actually bought this:
https://es.aliexpress.com/item/IPS-DSP-Android-8-0-4G-android-7-1-2-DIN-CAR-Multimedia-reproductor-de-DVD/32966026399.html[/url]
In different messages with the seller I told him that I wanted to keep all the functions of my original car radio, Steering wheel control, original mic, rear camera with dynamic guidelines (the guides move when turning the steering wheel) etc ... the seller told me that for that I had to buy canbus aswell. So I bought the unit and the canbus.
When the package arrived, only the device arrived and not the canbus. When I got in touch with the seller, he told me that the canbus is internal. Is this possible? I have connected the px5 to my car and the dyinamic guidelines do not turn with the steering wheel. I have also seen that pins A1 (can_rx) and A2 (can_tx) are empty, but it has a USB that comes out of the harness of the car. I did not connect it, it scared me. Could it be that it somehow connects there?
Can someone help me? Can the canbus be internal? If so, do I have to configure something? Have i been ripped off?
Please help me.
Thanks.

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?

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.

Chinese Headunit Canbus

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

I need help with my Junsun Head Unit!

Hi all,
I bought my first car 2 weeks ago, a Renault Clio 2014.
The first upgrade i wanted to do was a android head unit that supports android auto and apple car play. after some research i ended up with this one:
https://nl.aliexpress.com/item/1005003495893052.html?spm=a2g0o.order_list.0.0.291279d2UtKJ3v&gatewayAdapt=glo2nld
Model: PX9s 64GB 4G
€268,92
I got the radio in and it worked perfect, however i couldn't get the steering wheel volume controls to work.
After connecting the simplesoft box and pressing update on the head unit, the unit turned off and it remained this way... rip.
I think the unit is bricked. Im looking for somone who has the flash files or someone that has made a backup so i can try to restore the head unit
Keep in mind, im new to all of this.
I have found Junsun tech support to be very helpful.
Sorry I can't help any more than that.

I just got a t&t for a new unit, however as far as i know i can keep this one, is it possible to backup the new one and flash the old one with it?
Hi,
I'm new here too. I installed a Junsun V1pro HU on a Mégane 3. The canbus decoder is also a simple soft. Steering wheel control didn't work at first. Actually something was wrong in the harness and I had to swap the position of the 2 white wire of the smallest connector linking the canbus decoder to the unit.
I hope this can help.
