Hi,
After some reading in the forums here there is isn't much info on how CAN bus messages get into the unit.
My unit (Eonon GA5180F) comes with a GM Canbus decoder which works an decodes the ignition, lights, reverse into hardware signals i.e. all the normal inputs. But other data also makes it into the headunit e.g. steering wheel angle changes the reverse overlay and the doors opening/closing shows up on the display.
Would someone be able to point me to a more detailed description of how the can bus messages get decoded in the unit both hardware (does it go in via Key1 wire?) and software. Interestingly with all of the functions that do work my steering wheel controls don't - so I need to figure it out.
Thanks for any help!
Regards
Glenn
I am also interested in such a thing.
I wonder where the principle works show the climate, open doors....and similar messages that can be displayed on android car unit.

Hi,
In fact, there is a can-BUS decoder box, that is read.written through serial port on Android.

Hi,
I recently bought an Erisin ES2507B unit for my car.
I installed it and it works perfectly except an annoying
Issue with the swc. In general it works, but if for example i want to switch between screens in the car's dashboard, using the swc, and if i run the radio or another app that can be controlled with the swc, it also changes the radio station or the cd track. So i change the screen in the dash and the radio station at the same time. Annoying isnt it?
So as a developer i decided to try and "fix" that issue, somehow. The unit came with an external canbus decoder which i installed.
I am trying to find out how the headunit reads/writes to this decoder box.
Is this box a serial to canbus converter?
Is it a canbus to canbus converter, ie changes the car protocol to the HU protocol?
Is it a canbus to analog converter that converts the canbus messages in analog voltage? I think that the KEY1 and KEY2 are voltage inputs? (Not connected in my HU).
So if i am correct and this is a serial to canbus converter, how can i read/write to it?
The carservice app is not what suits in my case.
The ideal thing would be an app that catches the correct canbus messages and triggers the correct actions in the HU and HU transmitting to car dashboard.
Can you provide some info on my questions please?
Thank you in advance

Well compared to my everyday job, this is nothing. I have been analysing vehicle canbus protocols the last few years so this is not the hard part for me. The hard part is that i dont know where to start in the head unit. How does it handle the canbus? How can i set the baudrate, the filters, the 11bit or 29bit. There are no clues on that, or at least i havent found any yet. That is why i am asking for help.

I can only give some hints. Looking at the lower part of the picture I've uploaded you will see TXD RXD. Which most likely
is the series bus going from the can-bus decoder to the head unit. In my loom for KLD there are two wires going
from the can-bus decoder to the HU. One green, one white, ground is also supplied. Looks like a RS-232-bus. They are
present in the big black main connector. You should be able to catch that stream if you have the can-bus decoder for your
car.
Don't look at the upper part because this is a non can-bus version. Normally in Hyundai/KIA it's pin 1-13 or 2-14
being Can H and Can L.

I am attaching a photo of the wiring diagram of my unit. You can clearly see that it says CANRX and CANRX. So i guess that this has a canbus tranceiver in the board and the external canbus decoder only transforms the vehicle canbus protocol to the HU canbus protocol. Or it is serial rx/tx and it transforms the canbus to serial.
First thing is to figure out what the CANRX and cantx signals really are and then how these are handled from the HU.
Thank you for your time.
Edit : I cant upload the photo.
saw this
http://m.eonon.com/Accessories/Kits-Harness/A0575.html
I open my can bus decoder (VW) and only have one canbus transceiver, the CANRX, CANTX from head unit connect directly to MCU (STM32F072C8T6) USART1 pins (PB6, PB7) on can bus decoder. I'm able to replicate can bus messages with arduino and MCP2515 can bus board, but I can't figure what protocol for serial comunication use the head unit yet.
As far as I saw there is a process running on the unit responsible for canbus

This is what I know about my KLD unit with mcu.img MTCB-KLD2-v2.77.
Note: my head unit (Pumpkin KD-C0235) is a "generic" version which supports resistive-ladder type steering wheel buttons. My unit as sold does NOT support CANbus. However the main board is the same board used on many other models and I believe the MTCB-KLD2-v2.77 image will support CANbus.
1) There is a standard RS232 serial port, 38.4 k baud which is present on the main black connector (pins 2 and 12?) on the back of the unit. If you connect a terminal to this you can see data packets go out the TXD line when you power up and power down the unit.
2) The basic format of a data packet is a start byte (often 0x2E, but other values are possible too) followed by a "command" byte, then a byte count "n" followed by a block of "n" bytes, and terminated with a checksum across the command and data bytes.
3) This data packet format is apparently very common. You can see it in the Android apks for mtc serial interface (even though the actual serial connection to Android does NOT use packets of this format). You can also see it in the STC tools for programming the mcu itself.
4) The mcu software can receive and process packets of this format. Depending on the packet's command and data bytes, the packet can change mcu variables directly, or it can send a command to the Android CPU.
5) The mcu software also supports a second, PWM-encoded serial interface. If enabled, it comes in on the same wire as the UART TXD signal. The basic format is a start sequence, followed by 32 bits where a "1" is detected as a "long" pulse and a "0" is a shorter pulse width. If the format of the PWM frame does not in any way meet the timing spec, the entire frame is ignored.
6) The mcu can also send similar 32 bit PWM blocks out another wire; I believe it is pin 5 of connector "E" on my unit. The format of these PWM blocks is essentially the same as what can come in on the UART TXD line.

Can you post some pics of the steering wheel angle features, specifically how it changes the reverse overlay?
I'm asking because my car (BMW e53 X5) also has a steering angle sensor) and I want to see if it's possible to show steering angle overlay on the backup camera on my HU (which is an XTRONS unit for the BMW models - one of the newer oct-core ones).
Mazda 6
I have a Mazda 6 2gen and a headunit with Canbus input. One wire CANRX and one CANTX. I’m wondering if I can connect directly can-/+ from car to those wires?
The unit came with the decoder box for Mazda 6 but as far as I see there goes only reverse and brake wires to the head unit from the decoder. Steering wheel controls does not work, even if you try to connect K1 K2 wires from decoder to key1/2 or canrx/tx in the unit.
From the factory setting of the unit you can choose the Canbus protocol so is the decoder basically useless?
There are tons of topics about steering wheel controls and it’s not what I’m looking for. I want to see those climate and door opening infos on the screen.
How have you guys wired the Canbus to the unit?

Sorry to bump this old thread. This is exactly what I want to know!
Why is there a list to chose protocols in HU settings when they give an external box which is said to be specific for a car maker?
I just bought the new PX6 unit for my VW T5 (2009 with CAN H & L wires in the harness).
The can box decoder (model: "Raise") doesn't interpret any CAN message correctly, not even the ignition on/off and I just don't know which protocol to chose in the HU settings or if that would make a difference at all...
Please help ?

What did the reseller suggest the unit be set to?
I remember that I tried the same on a ES2709ge some years ago. I used list open files (lsof) to find out the port that the canbus app uses. Was something under /dev like you'd normally expect.
Second thing was to read from that port using cat or cu. When you kill the canbus app you immediately need to open the port yourself, otherwise the canbus app will reopen the port as it is restarted automatically. No need to know the serial parameters (baud, stop, ...) when yoir reader just reuse the previous settings. But as we don't know the serial communication it is hard to use it in a custom way.
I'd like to forward Google maps notifications to my car's KI menu, but right now I'd say it is easier to connect a second canbus controller (hardware) to SPI, I2C or another UART, instead of understanding and rewriting the default canbus app communication.

My Uniway / Asottu PX6 unit came with a red CANBUS/SPDIF box and I was curious how to know which protocol to choose - then I noticed that the plastic has the brand name molded into it. In my case, SimpleSoft, which was an option in the CAN settings. Maybe just look on the box for a brand?
So did you find out something in the end?
Chinese radio has TXD and RXD on the little white 8 pins connector on the back. These wires go to CAN box, that translates messages between RS232 TTL and CANBUS sides. Key1 and key2 use resistors with a different value for each button. Different radios require different resistor values and that is because Android radios have a learning dialog.
[PX5] Dasaita Head Unit or Peugeot 208 - 2014 - Radio & Steering Wheel not working
Hello all, I have an issue with my Android Head Unity for my Peugeot 208 from 2014. I have installed and attached everything accordingly and everything is (almost) working perfectly. Except for two issues...
Steering Wheel Study not working
None of my Steering Wheel keys are working currently. I have checked if the correct Canbus-option is selected in the settings (according to the seller it's the correct one), but I still have some cables hanging loose from the back of the head unity (KEY1 & KEY2), do I need to plug these into the canbus decoder, or just keep them hanging loose?
Radio FM not working great...
I got the radio working, but sadly, the connection/signal is static/bad. I have tried connected the antenna/radio cable to the white and/or blue connecters that fit from my car, but both should be connected I guess... But I only have one cable that fits it from my android head unit.
Hopefully someone can help me out... Since the guide from the seller is not helping at all...

Hi! I have a Peugeot wir PX5 too. From what i know the canbus is the only thing you need to connect. So when the canbus is connected, you don't need to connect the KEY1 and KEY2.
The FM is working great by my head unit. Maybe you need to go to the factory settings and change the settings for canbus and for fm ?

Thanks for the reply.. Sadly the seller is only responding with: "Connect key1 and key2 to your car wiring"... But I can't even find which wires are supposedly are the keys on my steering wheel, hehe. So I'm stuck! Thankfully, they're sending a replacement canbus, hopefully that one will do the trick.

Check that allí connectors from/to canbus and to the headunit are well connected (sometimes they require some force press to really be plugged)
On the link you provided there is a guy that commented that everything worked as expected including the SWC so....if you can't fix it contact your seller for support

On 1st photo the 3 "red" buttons are only working with the "original" factory installed "blue&Me" equipment, no other hardware can use or decode them.
On 2nd photo the 2 "red" button are only working with the original factory installed "blue&Me" equipment ad use to switch information on Factory Magneti Marelli multimedia/navigation unit during calls, with standard "simply" Alfa Romeo car stereo they are only working on charging disc from official CD Charger; no other hardware can use or decode them.
On some cases "non standard hard coded manufacturer swc" have funny responses; in my case Voice command button open the app carousel in my HU and the Open/close a phone call button activate the Mute function.
Check you Alfa Romeo Use and Maintenance Guide and Blue&Me User manual thaere was all the info provided by me.

I dont think it will make any difference, there is a way that MTCDTools can remap SWC on cars with CAN Bus, @ikerg can tell you how to do it or what thread its in.

Found said posts and they were for car which communicate with resistive signals via canbus (or something ), so wiring the canbus from car harness directly to key1/2 gives access to the buttons.
If Alfa uses no resistive signals, you wont get away with this.
GM cars like mine have the buttons via hardcoded addresses via canbus and you can only try to find those codes in android or mod MCU profile it seems... too nub to do so in my case.. trying hard

Theyre not the posts I was talking about - pretty certain theres a way to programme CAN Bus SWC.
Alfa 159s have CAN Bus SWC.
I've had a similar problem with my Alfa 159 when I installed a PX3 unit. However, for me all the SWC buttons except the centre button on the left set work (i.e. pic 1) and only the left and right SWC buttons on the right set (i.e. pic 2). It is weird as the buttons that do not work mimic the other buttons for some reason so it's like crossing of signals or decoding it wrong.
As I didn't find anyone else having a problem I assumed it was either the CAN bus decoder (I opened it up and flipped switch 4 which helped I think but maybe it isn't suitable?) or the connection behind the steering wheel is loose. I haven't got round to checking the connection (apparently it's simple to open) as I can still control most things.
BTW, my car had the blue&me installed from factory.
SWC on Alfa Romeo 159
H all, I just installed a new Android head unit in my Alfa Romeo 159 SW (2006) and all the SWC's work and I can map them from the app. Below I will explain how I did it, hope this will help.
My head unit:
Xtrons TE706PL
PX 5 octacore 4GB 32BG Android 8
My car:
Alfa Romeo 159 SW
Upgraded from original radio (so not the navigation unit)
My car did not have Blue&Me
Required hardware:
Dedicated CANBUS adapter
Connect2 (company that make it) CTSAR002.2 (product number)
Patch lead to go with canbus adapter
Connect2 (company that make it) CTMULTILEAD.2 (product number)
I ordered both from Amazon Germany from seller NIQ. The patch lead was included with the CANBUS adapter, just make sure to select the correct one meant for Chinese head units. Price was 60 euros.
Installation
The CANBUS adapter is connected between the original car connections and the head unit. This looks confusing at first (it has connections on three sides), but in the end everything only fits one way. On one side connect the patch lead, on the other side it is connected to the head unit and on the last side it is connected to the original car plugs. All these connections are very simple with plugs that only fit one way. (I did need quite some force to push in the 2 of the 3 original plugs into the CANBUS adapter)
As mentioned, the patch lead is connected to the CANBUS adapter on one side. On the other side you need to connect it to the KEY 1, KEY 2 and GROUND wire coming from the head unit. This was the only connection that is not made with plugs, so either crimp them together (which I did, very simple, but you need a crimping tool), solder them, or make another good wire to wire connection.
Important notes:
The connection need to be made in a specific order!
First connect KEY 1, KEY 2 and GRND wires
Second connect the CANBUS adapter to the head unit
Last step is to connect the CANBUS adapter to the car connections
My car did not have Blue&Me, so I don't know if this changes anything. I think I read somewhere you can just leave it in the car and not connect it. But maybe do a little research.
All this is also specified in the manuals provided with the products. Connects2 has some nice youtube videos on the CANBUS adapters, just google them.
I did quite some research myself before I figured it out, but now all is installed and working perfectly! I reprogrammed all the keys to my own preferences, including google assistant speech activation button.
Hope this helps!

Dedicated CANBUS adapter
Connect2 (company that make it) CTSAR002.2 (product number)
Patch lead to go with canbus adapter
Connect2 (company that make it) CTMULTILEAD.2 (product number)
I ordered both from Amazon Germany from seller NIQ. The patch lead was included with the CANBUS adapter, just make sure to select the correct one meant for Chinese head units. Price was 60 euros.
Installation
The CANBUS adapter is connected between the original car connections and the head unit. This looks confusing at first (it has connections on three sides), but in the end everything only fits one way. On one side connect the patch lead, on the other side it is connected to the head unit and on the last side it is connected to the original car plugs. All these connections are very simple with plugs that only fit one way. (I did need quite some force to push in the 2 of the 3 original plugs into the CANBUS adapter)
As mentioned, the patch lead is connected to the CANBUS adapter on one side. On the other side you need to connect it to the KEY 1, KEY 2 and GROUND wire coming from the head unit. This was the only connection that is not made with plugs, so either crimp them together (which I did, very simple, but you need a crimping tool), solder them, or make another good wire to wire connection.
Important notes:
The connection need to be made in a specific order!
First connect KEY 1, KEY 2 and GRND wires
Second connect the CANBUS adapter to the head unit
Last step is to connect the CANBUS adapter to the car connections
My car did not have Blue&Me, so I don't know if this changes anything. I think I read somewhere you can just leave it in the car and not connect it. But maybe do a little research.
All this is also specified in the manuals provided with the products. Connects2 has some nice youtube videos on the CANBUS adapters, just google them.
I did quite some research myself before I figured it out, but now all is installed and working perfectly! I reprogrammed all the keys to my own preferences, including google assistant speech activation button.
Hope this helps!

Thanks for the info, but what unit do you have ? - "TE706PL" is a made up name, your MCU will tell us what unit it is, I m guessing a GS ?

Sorry, I was not near my car, so couldn't find my MCU version. But here it is:
MTCE_GS_V2.88_3

I have a PX5 and have the same issue.
I see people talking about their chinesses mtcd/e read all the can protocols (open doors, all the swc, radio info to main pannel...)
Talking to my seller, he told me that may be the can decoder. Offers me a refund but I want one that works 100%.
¿Someone have the full functional decoder?

More likely that its just not supported, some cars have even less support.

That's what Im trying to find, a canbus decoder with more options.
I had the alfa 159 android 5.1 unit and It shows temperature, doors and full keys function. I upgraded to a new unit android 7.1 and now I haven't temperature, doors and only half of keys are working.
Dear all
I hope you can help me! as I cannot get anymore support from the hardware supplier -> his on-line shop has disappeared.....
I recently bought a PX5 HU with Andoird 10 but I am experiencing some problems with my Peugeot 308 "Park Assist" Can Bus messages erroneously and erratically popping up on the screen of my Android HU (see video)
I have managed to enter into the factory setting (code126) to set-up the canbus such that I can control the HU with my steering wheel controls, bat as soon as I select a working canbus protocol working with my car, I get also these nasty and annoying park assist popping up messages ..
This is making my HU not very pratical to use., as these popping up messages are pretty frequent
I have no clue how to remove these messages .. shall it be with an additional software on the HU, or Hardware, or with the car manufacturer, or the canbus decoder that shall be change to a one more specific to my car (Peugeot 308 from 2010)
I have tried to also update my MCU file... but this didn't help
Any help /recommendations would be very much appreciated
Many thanks in advance
Is it an MTCD device, post MCU version
Hi Marchnz
Thank you for your message
It is a MTCE MCU
I had the version [email protected]_V3.57_1 when I bought my PX5 and just upgraded it to the latest one I could find on this forum, i.e. the MTCE_MX_V3.71 5 with car logo ! ;p
But this has not helped me and I still have the same strange problem with the brief and intermittent canbus park assist messages
I am just wondering where I should start looking for a solution ..
Shall it be the CanBus decoder to be changed... modify or upgrade the canbus app in my HU, or the car setting app ???
Or maybe can I attempt to reprogram the steering wheel controls ?
How can I stop these fake park assist canbus messages to reach and be decoded by my PX5 head unit???
any software to be recommended?
Thank you for any help / advice you could give !

Sounds like canbus decoder, the role of the canbus decoder is to listen for vehicle specific canbus messages and signal the headunit.
Hi
I have a problem with the can bus
ciytroen c4 assembly of a dedicated chinese.
The problem appears after plugging the radio into the cube after the serial one, namely the canbus module beeps pulsating. I will add that the radio turns on, receiving stations, they can be operated.
I will add that after configuring the module in the radio settings, the steering wheel buttons work this way. means there is communication and it still squeaks. I tried to insert the bundle with the module also squeaks.
watch it

Hi
If you didn't manage to solve the problem yet...
You need to setup the can bus decoder in your head unit and then the beeping will stop.
If you need help just ask!
Cheers

Hi,
I'm dealing with the same problems.
Some of the car functions you can change over the car settings app.
And there should be a car info app which shows fuel consumption.
I'm still using the OEM multiscreen with steering wheel to change car settings.
But when using that I have the issue that all OEM displays get off and on during driving.
I'm trying to find a solution.

I bought a PSA-RZ-01 decoder. This one doesn't work with my android HU. Maybe I'll try the Hiworld decoder. Really annoying
Are these MTCB type head units?
Did anybody find a fix for this problem.
I have the same problem with the citroen c4 doing a selftest while driving.
And it keeps resetting the small display

True, but I think the problem is related to the canbus module. So wanted to check if someone with similar problems did find a fix
Hi to all. I finally got a newer Andeoid version for my headunit and now all informations I need or I expected are showing on my headunit.
Everything before the update wasn't shown now appears like doors open informations, ECU fault codes, fuel informations and consumption, AC informations everything is shown like a popup information. And all that withe the Rais canbus decoder. The small original display I kept cause of the missing informations on the headunit is now not needed any more.
If someone still have problems with the canbus all you need is to update your andeoid unit to the actual version for your unit.
Can you advise what your canbuse settings are ?
Inside of the factory menu ?
I just installed a android T10 unit with a Raise canbus module. But only thing that is working on my Citroen C4 are the volume buttons...and even that does not work correct. I i press the menu button on my steering wheel sound also go up

do you mean the newer version of the headunit or can.apk? I have done both and despite selecting different models the problem exists.. (My MCU starts CVD)

Have you gone to Car Settings under factory and selected the relevant file under Can Setting? R011 is for Citroen C4 where the steering keys work fine, however my instrument panel keeps flicking between kmph and mph..
R016 works fine but only volume buttons work and the display screen thinks CD or radio is on.. (see picture)

In my android radio version, I didn’t see anything like “R0..” When I choose version of canbus “raise” -> psa/Citroen -> I have only models of car and I get C4L. Everything works like steering wheel buttons but I have problems with resetting displays and appearing diagnosis.
