How do CAN Bus messages make it into the unit?

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.

New owner here!...... need help with a few questions. Thanks!

Hey guys,
I just bought a new unit and have had fun installing/setting it up. But I've run into a few problems/questions that I can not easily solve from searching. I'm hoping for some help. I appreciate any insight that can be provided!
purchased:
MTCB 800x480 (EONON GA2114)
1.) I can't get the reverse camera to work
My previous head unit was the Astroid Parrot Smart and my backkup camera was working. I've setup my MTCB as follows: HU reverse wire to reverse light 12v & HU "cam in" to camera's RCA plug. I'm experiencing: when I put in reverse gear, I get a yellow triangle exclimation point and no proper video. Could this be becuase I have not grounded the HU parking wire (everything else is working properly without having to do that. Is there a setting somewhere I need to change?... pal vs ntsc?
2. ODBD not working correctly.
I can connect to it in bluetooth settings but Torque can not connect to it. I do have blue OBDB icon that appears in the taskbar
3. Keypress (for the physical hardware buttons) volume is too loud
even if I have the radio volume turned all the way down
4. music volume is too loud when volume set at one
With the volume of music at it's lowest setting, it's at a normal listening level.
5. Elements in Settings disappeared
It's just gone. I can't change the physical button colors any more. It was there before.
6. Saved radio stations.
After a scan is complete.... I can't figure out how to reorganize the order of stations.... or even delete the unwanted presets
7. Best way to automate wifi hotspot?
Should I set a tasker action to start hotspot upon bluetooth connect to unit? I sometimes have bluetooth manually turned off though. ... what's everyones solution to this? I though about a NFC sticker placed on my phone dock to automate bluetooth/hotspot.

When you say parking wire I assume you mean park brake wire. The park brake wire has nothing to do with reverse video. It is suppose
to turn off DVD video during driving. Which can be changed in settings BTW. Exclamation point normally means no video. Are you sure
you used the right input and that your camera is providing video? Test your camera on a normal video in and verify if you get a picture.
Also verify that your reverse camera gets 12 volt when selected.

Dasaita V600 Head Unit not switching to reverse camera

Finally installed a reverse camera on my BMW E46, all cables are right connected and the camera is working during a test on workbench.
My Dasaita V600 head unit (MCU updated to last 2.80 version) dont have a "reverse signale cable" but is supposed to switch in reverse camera through the canbus (E39-E46 software V1.0) so my camera is only connected to "CAM-IN yellow" cable for HU.
Putting reverse gear (motor running or not) the head units dont auto switch to "CAM IN" input for showing images from camera. Anyone had this issue? Any help?
P.S.: If the camera is connected to "AUX Video IN" and manually started AVIN app images are on screen, so no troubles with camera and/or connections.
Thank you in advance

The options was enabled by default on my unit. Tried all options and deep searching for a "software solution" without luck.
Only working thing i find was cutting a wire from canbus box and direct connect the other side from my HU to reverse signal wire from my auto.
I think that was caused from BMW E46 I-BUS signals not fully decoded from canbus, i have retained all steering wheels controls but not doors open warnings, if they are supposed to show on HU display.
If anyone have some advices they are welcome.
P.S.: In my case working for steering wheel controls setting are NO CANBUS. If i try to select another BMW voice from list i lose steering wheel controls.

Can you tell me what wire you cut and connected the blue from reverse light?
BL/GE - Blue/Yellow wire
I understood that it was a wire between the headunit and the canbus decoder.
(on Automatic Gear Box it seems it works just fine)
I know that the data is send and it works The Ibus is able to detect the msg, this decoders just don't catch on older veicules with Manual Gear Box.

i used the wire number 2 labeled "reverse" on HU side, but you need to be sure that your HU is a Dasaita for BMW E46.
Check the wire/connection label on your HU for confirmation.
P.S.: On kmy case the wire was orange

I don't think it's strictly Dasaita, as this is the same for Eonon as well. I had to tap into the blue wire between the HU & CANBUS converter. I have the power for the camera tapped into the reverse light.
I too have an E46 Touring. I'm curious, where did you mount your camera? I put mine right above the licence plate dead center of the hatch release button. It's a perfect spot! I removed the torx screws and slid it behind the plate light bracket and ran the wires through there as well. It works fantastic in this location and it even assists when connecting a trailer because it's close to the hitch.

I've seen cameras that replace one of the lights. I thought about 3D printing an adapter but I went the route I did to keep both lights and have the camera dead center.
Yes, but you need the I-BUS interface to do that. The Canbus converter doesn't do much. With the I-BUS interface & I-BUS app you're able to see what doors and windows are open, what lights are on, and you can code your car as well.

Xtrons TQ709IPL Reverse Camera Setup

Hi All,
Just purchased the above unit and it seems pretty good so far, stab;e, etc. Just trying to get the reverse camera working, does anyone have any experience with this brand as the wire labelling is confusing.
The 4 wires in question (as far as I can figure) are:
CCD AVIN - Referred to as Reverse Cam Input)
BACK_CAR - Reverse Control Cable
on another connector
REVERSE - Reversing Control Cable
BACK SIGHT VIDEO - Reverse Cam Input Video
You can see where my confusion would be.
At this point, I've connected the camera 12V supply to the reverse light wire so it will turn on when in reverse gear. Would this also need to be fed into one of the control cable wires (Do they require 12V to switch to the camera input).
Thanks
Paul

I just ordered the same xtrons unit, I'm planning to attempt to only use harness1 (connections 1-9), and the associated reverse control wire (5) and yellow rca input (3). I assume the other input on the 2nd harness would work fine too, but I want to keep the clutter down behind the new HU.
Your car might provide the needed +12 reverse control wire in dash already, if it doesn't, you can tap the same +12 your using for the camera itself since it sounds like you correctly wired the camera in a way that it is only powered on when actually in reverse. I've seen lots of people wire the cams power source to either always on +12 (really bad) or acc +12 (kinda bad).
The +12 control wire tells the unit to switch to that camera input for the display. This is why i think it can use both reverse inputs, so long as you use the control wire for its associated rca input.
I think this unit has multiple inputs for maybe a trailer camera in addition to the reverse cam, maybe a toggle switch attached to harness2's "reverse control" instead of actual reverse, that you could switch on manually and then see the other camera input as needed.

I finally wired up the reverse cam to the TQ709IPL. I only used harness1's connections:
Harness 1:
Pin 3 CCD AVIN, Reverse Camera Video Input
Pin 5 BACK-CAR, Reverse Control Cable
These two pins worked perfectly together, +12v on Pin 5 "BACK-CAR" and the unit switches to show what's plugged into Yellow RCA Pin 3 "CCD AVIN".
Unsure about these connections still:
Harness 2:
Pin 22 REVERSE, Reversing Control Cable
Pin 25, BACK SIGHT VIDEO, Reverse Camera Video Input

Hi Im planning to replace my factory headunit (no built-in amps , 6 speaker without sub) , if I replace it with this afermarket Daisata HU , will my factory rear and lane watch(right side mirror) camera will work and steering whell control??anyone got their aftermarket HU works with CRV 2015??TIA

I think all will work, because it's always the same Honda Connect system. I'm driving a HRV 2016 with a Dasaita HU. All fine. Take a look at this thread for more infos: https://forum.xda-developers.com/an...nda-hr-dasaita-ha5248-v480-8-android-t3858168

OEM rear cam & lane watch doesn't work (for me) maybe you need to wire something properly (haven't found a good installer who can)
canbus is not 100% working (phone talk button from the steering wheel, imid display (like clock etc.))

Dasaita (hot-audio.com) HA5248-V840-8
8" Android 8.0 radio upgrade
They advertise this unit as having full stock functionality with both cameras and features. I can happily say that it is exactly what they say it is. I have a lot to say so read carefully if you are considering purchasing this unit. Hopefully I can help.
Brief rundown:
All the cameras work and the unit even retains the MPG and trip mpg history features. The unit also adds some features like graphical door ajar indicators. Plug and play with some configuration through a password protected factory settings menu. (password is 126). Steering wheel buttons work and are programmable. This thing is LEGIT!
Cameras:
With a little configuration they both work just fine. The Lane Assist camera has the distance lines programmed in to it so they display automatically. The reversing camera settings include options to show trajectory as well as a distance ruler too.
To properly route the signal for the Lane Assist camera in a USDM HRV EX I had to do the following:
"GO to Settings >Car >Factory Setting (password 126) >Other >Customer Version >Version 2"
In "Settings >Car >Extra Settings >Reversing Volume >On" or set the reverse volume to the desired attenuation. Otherwise as configured by the factory the audio will cut out when the reverse or Lane Assist cameras are active.
(The "Factory Setting" menu has a lot of other configurable options that are vehicle specific. Password: 126)

I dont know about the HRV but as par as I know the CRV has a different canbus. I don't know if this canbus (PAC RP4-HD11) is better than the one the dasaita included.
according to some the rear cam work if you power it with 12v too bad I already installed an aftermarket rear cam before I learned about that trick.

I dont know about the HRV but as par as I know the CRV has a different canbus. I don't know if this canbus (PAC RP4-HD11) is better than the one the dasaita included.
according to some the rear cam work if you power it with 12v too bad I already installed an aftermarket rear cam before I learned about that trick.

I ask daisata support and they told me I need a HRV vezel canbus CB015 to retain my factory cameras..I ordered it yesterday and i'll check if it will work on vezel canbus..
