Hi bantroi.

My box is also a Bagoo one. I don't remember sw-hw version but I'm sure it's from Bagoo.

My Alfa 159 was built in 2008 but I think its a '07 model year, wich year is yours?.

You can try the following:

Go to factory settings and enter "logcan" (or "canlog", I don't remember)

You will see the key codes from canbus decoder when a swc key is pressed, check that every key generates a code.

If you don't get a code for some keys, it's most likely because of canbus box not being compatible with the car. Maybe different model years have different canbus codes and the Bagoo box is not updated for that.

A possible solution would be to implement some kind of DIY canbus reader, with an Arduino or so.
[MTCD  Android Head Units Q&A] bantroi:
Ok, thnx.

Mine is from dec 2007.

May be the same.

Ill try your info.

My Xtrons HU PB68WRJP with Can Bus (Bagoo), has a little annoying problem with the faceplate panel illumination. The illumination is working only if I switch On the Headlights manually. Typically I have the lights in "Auto", but in this case nothing happens when the headlights are on.

I know that the control is done by the Can Bus and I tested all the possible combinations under the Factory Setting:

- Control by Headlight

- Control by Power

- Control by Power and Headlights

With the "Control by Headlights" setting, I have the previous behaviors, with the other settings I have the illumination permanently On.

Anyone can help me to solve this issue ?

Thank you in advance.

I have a Joying FYT unit, but still have trouble connecting the canbus box (for Opel Vectra) from another radio I bought (MTCD). The Joying unit does not have RX and TX connection in the connector. I know they also have FYT units for VW with working Canbus connection, showing airco, doors etc.

I currently have it connected like this:

Since I don't know what to do with the RX and TX, they are disconnected. Maybe I can hook them up somewhere inside the radio.

What I also tried to do is retrieving the output of the TX pin of the canbus box. I expected some serial data, but got some unknown signal (for me). Does anyone know how the communication between the canbus box and headunit works?
[MTCD  Android Head Units Q&A] Bo03:
With this setup you can try now combination of Can H, Can L with Key1, Key2.
[MTCD  Android Head Units Q&A] Pachis83:
It's matter of the headunit, not the canbus box.

I have a PX5 MTCD XRC unit and it's happening the same for me. Previously I had a PX3 MTCD HA unit and using the same canbus box the illumination was working ok.

I think the only solution involves modifying the headunit arranging illumination connections.

Regards.
[MTCD  Android Head Units Q&A] HaTeNL:
Any reason why that would work? What I did try was connecting TX and RX to Key1 and Key2, with no success
[MTCD  Android Head Units Q&A] Bo03:
So, how many options are left?

In pinout of my car's headunit connector are In0, In1 Can H, Can L.

No ground. Canbus communication is on voltages. Each command sends different voltage that is read by headunit. Try, not much to loose.
[MTCD  Android Head Units Q&A] royalhawk2002:
I don't know how to modify the connections. The Illumination wire (orange) is coming out from the Can Box to the HU. There is no way to tap an illumination signal from the car, because the signal is handled by a Can Bus Message. The strange thing, as said before, is that in manual the illuminations is working. This means that the Can Bus can decode the Manual signal but not the "Auto".

This thread seems to be the best source on the internet :)

So I have an Alfa 159 and just bought an Aliexpress Android head unit.

There seems to be some trouble with the Canbus decoder which was a Bagoo brand.

When I put the key in, the unit turns on. However I get no steering control or illumination etc after that. Furthermore when I take the key out, the unit stays on. Therefore I conclude that there is some communication issue between the headunit and the decoder. Or maybe the decoder goes into an unknown state after start.

If I do a reset, then everything starts working. However I don't want to reset the unit every time I start the car.

Has anybody experienced something similar?

Has anybody tried sniffing the UART signals coming to and from the decoder? I am thinking of trying this.

The dealer sent me a new firmware for the unit, but it fixed nothing. I don't think the decoder firmware can be upgraded OTA or from within android?

Audi A6 C5 2002 Avant - Android 7.1 MTCD - Canbus Bagoo Audi-BG-04

Hello everyone. Found this thread too :) Maybe something will be interesting or anyone may advise anything.

Audi A6 C5 2002 Avant. In stock was Audi Concert CD, then replaced it on Audi Symphony 2 - both devices has no any problem and controls through CAN Bus interface. Now I've buy Android 7.1 Multimedia Player (MTCD) with Canbus Adapter (Bagoo Audi-BG-04). Media Player works good, but there is problem with one of function Canbus Adapter - it's incorrectly transforms Ignition ON\OFF signals from CAN interface (shows OFF if turn On ignition first time after connection, and then shows permanent ACC ON after removing key from a Ignition lock). Illuminations works correctly, steering wheel control can't check right now - will install it later (stock steering wheel without media control buttons).

In Settings can not find any menu item related with setting for Canbus (maybe need change car model or something like that, because on Canbus box mentioned only TT/A3/A4 and not sure or their CAN signal are the same with A6 model). Therefore don't know, is it software \ firmware \ hardware \ compatibility problem or something specific only for my Canbus Adapter.

Below photos and details about my Multimedia Player and Canbus box.

I found the Canbus menu.

From Infotainment Settings -> Device Info

You click the cog on the top right. And from the numpad, the pin is

8888

There you can choose car brand and model for the Canbus adapter.

I set mine to "Fiat (all)" and it seems to work now. (My car is Alfa Romeo 159)

[MENTION=9727992]kanapeshka[/MENTION]

I think you will find the same menu on your device too.
[MTCD  Android Head Units Q&A] HaTeNL:
Yes I tried sniffing the signals coming from the Canbus box, but these werent normal serial messages. I couldn't decode the signal. I had set the baudrate to automatic.
[MTCD  Android Head Units Q&A] Pachis83:
Go to factory settings and instead of code "126", use code "canlog" (or logcan, I don't remember).

You will see the decoded key codes sent by the canbus box.

- Key mode

- Swap_key

UP!

Well.

I finally managed to open canlog. But when open it it shows nothing. Only this black screen with some buttons and no matter what I do, it shows nothing (no log).

If you have a bagoo and a 159. Wow is your harness.

My adapter and radio has this connections, maybe the problem is in the wiring.
[MTCD  Android Head Units Q&A] kanapeshka:
FYI, maybe anyone will have same device. In the main "Settings" menu there is "Factory Settings" field. Tried a lot of passwords that were found in Google (like 126, 8888, 0000, 123456, 7890, 5678, 3368 etc), but none did not worked. Funny, but in my case password was "m123456" :)

I've tried and "Simple"(A3/A4/TT), and "Bagoo"(A3/A4/A6) manufacturers - in both cases still there is problem with incorrect transforming Ignition ON\OFF signals from CAN interface. Interesting or possible somewhere buy a new CAB Bus Adapter for test, because I'm already almost on 100% sure that problem in this Black Box.

Idon't know where to post this :)

I have a fiat grande punto 2009 model with an Isudar unit MTCE_GS_V2.78_1 MCU version. After I have changed the SWC with the 8 button type, and I have changed the illumination LED's on the board, I returned to the 6 buttons model on wich I also changed the illumination LED's on the board.

In picture 1 and 2 are the SWC buttons. In picture 3 are the codes my SWC are showing in the factory settings using "canlog" code, and in picture 4 are SWC codes from a friends car.

The problem is that 1, 2, 3 keys are only doing "vol -" and 4, 5, 6 are doing "previous".

Does anyone have an idea on where the problem might be? Thank you!
[MTCD  Android Head Units Q&A] nic2k:
I don't quite understand what you're saying by you changed the SWC with 8 button to 6 button but if you get the same code for all the keys on the same side then you must have a short circuit between the keys. Maybe you swapped SWC buttons of the wrong type. There's analog buttons (resistor ladder) and digital buttons (key matrix) make sure you have the correct type for your car.
[MTCD  Android Head Units Q&A] dberladyn:
I am not sure that this is going to help anyone, and I am too lazy to take pictures of the board right now, but I have started a page to at least collect the information about my CANBUS DECODER. If anyone has the same type of decoder and would like to double check my wiring scheme and any other information that would be great.

[MTCD  Android Head Units Q&A] TheDiB:
Hi guys.

I've had a bit of struggling since months now with my MTCE units in my french Peugeot 308 (2009)...

I have tested two head units (a "Belsee BP3" and a "MEKEDE MKD-P737") and both have the same issue : the car service counter is going nuts !

Each time I start the car, the service counter drops to 0 Km and the service light turns on.

I have to reset it each morning wich is pretty annoying.

The 2 head units came with 2 different canbox (see attachements).

Can you help me identifying those decoders, where they come from ?

Which manufacturer do they come from ?

What canbus profile should I set in the head unit ?

Is it possible to upgrade it ? fix it ?

Thanks in advance !

Kind regards,

Damien
[MTCD  Android Head Units Q&A] cleverdicky:
Hello, I have a little problem others may sound familiar.

My unit is a px5 but has canbus reader is built in. There is no external box.

Lately im getting intermitant problems like not turning on when car starts, no adjustment from steering controls etc.

Otherwise it works fine. I suspect a lose wire or bad solder joint as on occasion when it doesnt start up, if I give the side console a bang it works.

But could it be a fault on the canbus itself ?

MTCD Android Head Units Q&A

CanBox versions by Wadzio

Anyhow, I had hoped someone might recognise the concept of having on board can adaptor.

Having a possible software glitch / hardware fault I've stripped the unit down to better understand what's what.

First off the large 40 pin connector rather than messing with extra wires and a box, plugs straight into the back of the unit.

Saves a lot of room.

From there it connects to a daughter board containing a top of the line?? ST micro controller STM8S208 which includes a canbus decoder.

Pic.

I wonder if anyone recognises this from any of the external adaptors ?
[MTCD  Android Head Units Q&A] marchnz:
Image doesn't load for me.

From fault description software is unlikely. Mechanical force hints to hardware.

Try tapping board with non metallic object while powered on to diagnose solder/component dry joint.

[MTCD  Android Head Units Q&A] JohnJay.:
Just a suggestion from the issue I found myself having.

After I installed T'eyes CC2 plus in Astra J the CANbus protocol showed as 'unknown' so it bugged the hell out of me as it is a brilliant little device with truly excellent sound (compared to cd400 factory unit)

I was going back and forth with seller, who was there for any suggestions we may have.

All of a sudden it dawned on me; pushing the CANbus wire ( double white wires into 8 gang connection) was a hard to push into device. So I checked and One of the tiny pins was bent slightly. So I got a pair of reading glasses and a medium sized sewing pin and used that to straighten it. I was confident I had fixed it because it went in a whole lot easier 🙏

So you never know if you have an issue where your CANbus decoder isn't working (no door open notifications, A/C, cd409 buttons or steering wheel buttons working)...

It is possible Trust me!!!

Good luck to anyone in a similar situation.😉
[MTCD  Android Head Units Q&A] bhudcser:
Alfa 159 owners! Have you been able to show door status, brake, maybe ac and other information through Bagoo canbox decoder? Dimming backlit when turning up lights can work also?
[MTCD  Android Head Units Q&A] typos1:
I tried my mates Alfa 159 GS MTCE unit & BAGOO decoder on my Alfa GT and I got door opening warnings, dimming headlights and voltage/outside temp in the status bar ! There is no app with vehicle info when MTCD/E units are set to Alfa CAN Bus mode like there is for the VW units though. This is all down to the head unit rather the the CAN Bus decoder - the info comes through whatever make the decoder is. I have been meaning to set the CAN Bus version to VW, extract the vehicle info app, go back to Alfa CAN Bus mode and install the VW vehicle app and see if it works, probably not, but worth a try.
[MTCD  Android Head Units Q&A] noe9:
Well the biggest downside i found with my Alfa 159 Bagoo CAN box and the MTCE unit is that the incoming call pickup button always rejects the call (the AR steering wheel only has one button for pickup and reject)

I also saw that someone mentioned that they managed to get dynamic parking cam guide lines working, found it interesting as i didn't expect the steering wheel angle being transmitted)

Back a few years ago I used to have a Parrot CAN box with their handsfree and it would work perfectly with all the AR159 steering wheel functions (it even started a contact list voice search when you wanted to call someone)
[MTCD  Android Head Units Q&A] noe9:
Diming lights works for me on with the Bagoo box and switching to day / night mode

I don't have any app to read Door/Brake or AC info

Call pickup doesn't work correctly as it rejects incoming calls
[MTCD  Android Head Units Q&A] typos1:
Have you tried long pressing the button ? You can also over ride the CAN Bus and programe the SWC yourself, though I forget how now, I think you need to be using a custom ROM, but as MTCD/E units support 2 presses (long and short) on SWC buttons it deffo can be sorted.

You should be getting the warnings over the screen though
[MTCD  Android Head Units Q&A] JohnJay.:
Is it some hidden or obscure setting in your phone, not allowing the HU to answer?

As an aside; I remember when I had just Bluetooth on my factory unit it used to cost a fortune calls going through the car??

But ok since I fitted the CC2plus 🤗
[MTCD  Android Head Units Q&A] noe9:
The Long press didn't work for me, neither on the stock ROM nor on the HAL9k v4 ROM (PX5 based unit)

I recently switched to a PX6 unit, with Android 10 on it, still using the same CAN Box, with the same effect.

I could never get the SWC button programming App to work for me, no clue what I'm doing wrong.

It seems to me that the Bagoo Alfa CAN Box SW maps the call answer signal to call reject for some reason.

Both of my units came with the same Bagoo CAN Box and same SW/HW version. Did anyone seen a different CAN BOX for Alfa's (or other Fiat brand cars?)

Is it perhaps something that can be configured in the factory settings menu?
[MTCD  Android Head Units Q&A] noe9:
Well you can answer on the HU, just not with the Steering Wheel button ;)

Unfortunately not dedicated Teyes units for Alfa's and im stuck to Rockchip or AC8257 basd units
[MTCD  Android Head Units Q&A] typos1:
The CAN Bus is controlled by the MCU so what SoM you have wont change anything. As I said you can remap SWC buttons - normally you cant if you have CAN Bus but there deffo is a way to over ride this, you need to search in the forum for how to do it as this is the solution to your problem. ALL MTCD/E units are short & long press compatible, if theres no long press set on the phone button, when youve found how to remap the SWC by searching the forums, map short press to one function and long press to the other then you can answer and end calls using the same button.
[MTCD  Android Head Units Q&A] noe9:
So today i did a bit more research in the factory mode. Turned out that the CAN Box is NOT configured under can settings.

The issue is that if i attempt to select the correct Bagoo Alfa CAN Box type, the SWC's stop working completely.

There are 4x "types" that can be selected but none of them worked at all (nor did they allow for SWC key programming).

Any idea what could be the problem here

MCU is MTCE_LY_V3.52_1
[MTCD  Android Head Units Q&A] typos1:
On some cars you have a CAN Bus box but you select "none" under CAN Bus in factory settings.

I have told you how to sort the problem and it is not in factory settings.

Your MCU version is irrelevant.

If you want to sort your problem then follow the advice I gave you earlier - search the XDA MTCD forum (using the forum search or google) for how to change SWC functions on cars with CAN Bus., as I said, pretty sure you need a custom ROM, it may involve MTCD tools, but there is deffo a thread on it and when you find it its highly likely that I have posted in it.
[MTCD  Android Head Units Q&A] noe9:
So yes, i finally got around and found the time to play more with the HU.

I installed the recent 1.10 version of MTCE Tools to look what possibilities of re-mapping i have.

The issue i found is that basically out of the 4 buttons that i need to fix:

- Two of them are not being read at all (skip / previous)

- Call answer & Voice control are both read as code 317

- Call answer - No difference between long press & short press (code 317 will be sent multiple times)

So the best thing i can try given the above is to potentially re-map code 317 to answer call vs. reject call.

The factory settings as you mentioned in your post above are set to "NO CANBUS"; as selecting the Alfa Bagoo BOX disables SWC control completely.

So now my question is this a limitation of he Bagoo box / FW?

Whats interesting is that @SJ1977 claims that he managed to get all the buttons working with a CTSAR002.2 CanBus adapter:

[MTCD  Android Head Units Q&A] typos1:
I have an Alfa GT as well. The GT (and 147) has CAN Bus, but it has resistive steering wheel controls, the 159 has CAN Bus and the steering wheel controls are CAN Bus too. The CAN Bus you are using is really meant for an Alfa 159, not the Alfa GT (or 147). I use this CAN Bus box too because it also works with most of the functions on the GT, but not all functions because it is meant for the 159. You need to use @Hal9k_'s cutom ROM (you may have to downgrade to Android 9 until his 10 is ready) because his ROM lets you over ride the CAN Bus steering wheel controls - at the moment they are set to CAN Bus controls because it is an Alfa 159 box you are using.
