In fact, in this case it IS a matter of CANBUS box. The box outputs the "headlights-on" signal on output wire, and not sending it to the unit via serial port. This wire is just connected to the ILL wire of the unit.

I have the same problem with JEEP CAN box on my unit - XTrons MA70WRJLS and I will solve it by connecting the ILL signal from A/C control box illumination directly to the unit, and disconnectiong the ILL wire coming from the CAN box. It is a shame - coding it in the firmware would be really simple, but there's no source available.

Hello.

Raise PSA-RZ-15 canbox and Topway TS18 serial H.U. I have.

How can I interfere with Canbox? Is there an external settings app?

The parameters I want to set are HU wakeup when the door is opened or the lock is unlocked.

The HU continues to run for a while when I turn off the vehicle engine / ACC.

Getting the MUTE position when I press the Volume down and you on button at the same time from the steering wheel control.

Thanks.

I had to replace the canbus box in my head unit because it wasn't working properly. The previous software is also used for the new canbus box. In such a case, should the first canbus software be deleted? If so, how and where can I find it? The two canbus boxes are not from the same manufacturer, so they are different.

The car's EV menu was not visible with the canbus set supplied with the aftermarket head unit. That's why I bought another canbus set, but I can't see the EV menu either. However, the second canbus set also runs the same can software as the first. It is fine?

My car is Hyundai ioniq electric. Out of curiosity, I set a completely different brand of car in the canbus setting, then the EV menu was visible. Why is that?
[MTCD  Android Head Units Q&A] MegaBytesMe:
Hi, sorry for reviving this thread, however I have bought a very similar head unit for my Alfa Romeo 159 (PX6 with the DVD drive and the same Alfa fascia as yours).

I was wondering if your one worked without the key in the ignition? I like to use the radio without having the key in (as having it in the MAR position drains the battery much faster) however the unit turns off as soon as the key is removed or the engine turns off, unlike my OEM radio (which could be turned on or off at any time regardless if the key was present).

I think the canbox adaptor controls this, or the software side of the headunit does. I have the bagoo alfa-bg-01 adaptor which otherwise fully works with my steering wheel buttons.

Any ideas on how I could get the radio to work with the car off or without the key in the ignition? Thanks!
[MTCD  Android Head Units Q&A] Anton TNT:
Impossible, as key ACC turns unit and starts canbus box which operates with car.

It qould be possible if red / yellow wires are to be swapped, meaning if you swap yellow wire which is memory or 12V constant battery wire with red one ACC key ignition it could activate but will be and stay activated even if car engine is off, possibly will drain its battery and battery will go dead.
[MTCD  Android Head Units Q&A] MegaBytesMe:
Interesting, thanks. How does the OEM unit do it then? As it seemingly always has power (regardless of car power state) however turns off automatically when the doors are opened or when the key is removed AFTER the ignition turns off (remains on otherwise). I know the steering wheel controls did not work unless the key was inserted or the engine was on (after being shut off)...

Would be great to know how the aftermarket headunits work regarding turning on and off. Is it all controlled by the canbox? Or is it controlled by the software/hardware on the headunit? Is it as basic as a 12v input acting as a switch? I'd imagine it wouldn't be too hard for me to make some form of relay circuit/adaptor which could make it function as I desire while letting itself turn off at the right time.

Also, I know it has a sleep mode function as it lasts about an hour until it needs to do a full bootup (which takes a minute annoyingly each time). In theory it must have some power coming in to keep it in sleep mode? And if it does then surely it must have some ability to turn on?

Thanks
[MTCD  Android Head Units Q&A] Anton TNT:
All I know of these aftermarket units that car ECU and canbus (dependent of car model) controls unit behaviour.

Canbus settings are to be correct with car model in factory settings in order to function correctly. As far as car settings and unit timeout, this is only to keep it in memory and run faster every time you stop like on five minutes or so and then go on again.

Canbus boxes and its software can't be edited or changed. They are fabricly set up for each car model.

One thing you can do only is to go to mechanic and perform diagnostic of car, put it on computer and then edit some car options like radio switching on /off etc.

For example my car Peugeot 308 has a battery life savior, it is called safe mode or something like that, thing is if radio works for like 15 min that system deactivcates radio and cuts electricity to it so basically goes offline and saves battery for startup of car. Unit can drain battery faster if non-stop online, remember that.

Hello guys, i have a big problem with my radio 2 din on my alfa 159....my canbus decoder Bagoo Alfa-bg-01 has emitted smoke due to a court-circuit and it's not anymore working, the car radio is working but i lost all my steering wheel comand, reverse camera, door open.

how can i buy this decoder? it's really hard to find the same model online.

i have the v101
[MTCD  Android Head Units Q&A] Anton TNT:
Hi, buy a new canbus box, this one is fried and cannot be saved. You can ask your seller to provide you with new one or buy it from ali express on your own.
[MTCD  Android Head Units Q&A] laser01:
my seller unfortunately is not selling this canbus anymore also is not selling either the radio it self.....did someone know how can i buy? searched on aliexpress but the same model is not available....the other canbus work well?
[MTCD  Android Head Units Q&A] alecxs:
yes, but you need to find proper replacement. share some pics and get macro shoots of pcb inside.
[MTCD  Android Head Units Q&A] Anton TNT:

[MTCD  Android Head Units Q&A] Anton TNT:
According to the software version on board , similar device is this Chinese IDOING on Ali Express, but you have to contact this store / seller of this canbus device and ask him correct model for your car model (like M. BENZ C200 year xxxx)

LINK: https://es.aliexpress.com/w/wholesa...idoing+canbus&spm=a2g0o.productlist.1000002.0

Also , if your modelof car is Mercedes Benz C200 or something else find your canbus box also on Ebay , type in your car model and canbus box and search for best fit (must be for your car model!).

Nope it's an Alfa Romeo 159....in fact I was surprise when I read "benzg"

Btw the 2 MOSFET in the upped side and one is fried the number is 4803A, and the lower chip is 5CL8.....

I was thinking to buy only the fried MOSFET 4803A and try the connection pin one by one.

before purchase check with seller of this canbus if it is proper for your car model (pin connector of canbus and wiring connectors for radio unit, etc. - if is 16 pin for canbus).

I think this canbus will do great - HIWORLD model , best at the market and compatible with all car functions.
[MTCD  Android Head Units Q&A] alecxs:
you can try to repair. don't forget to reconnect drain on pin 7 on the left one.

[MTCD  Android Head Units Q&A] seninnha:
I am having same issue as you had with your Alfa 159.

After installed the unit NO steeringwheel controls or Car info is working.

I read throu all this topic and also tried to change the pin-out of RX and TX (in my case is RDX-CAN and TPX_CAN.

Swapped them insinde the connector going to the HeadUnit but still no luck.

Made a drawing of how my CANBUS adapter (BANGOO BG-O1 V101) is connected.

Maybe someone can see a problem there.

Like I already said , changed possition of PTX and RTX but that did not the job.

On my HeadUnit I can only assign the right Canbus adapter, and that is all correct.

is BG alfa Romeo

Somehow volume control is working fine. No idea why??

Telephone button opens BT app, and button next to that opens Google

Cant find out to change them

Doors are showed on my screen,but Airco controls NOT.

No idea why

Porebno ti je samo dovesti acc t jest plus sa kontakta na crvenu zicu i medija radi to bi se moglo izvesti pomocu prekidaca recimo onog na daljinski a sto se tice toga sto se medoja pokrece iz pocetka to je mene jako nerviralo i mislim sa je to samo do canbusa i nema veze sa praznjenjem akumulatora i ja sam to resio tako sto sam izvatio crveni provodnik iz canbusa i na njega doveo acc sa auta. A moj problem je i taj sto mi canbus ometa daljinako zkljucavanje i mialim da je to do nekompatibilnog canbusa marke Baago

Mod translation: You only need to bring the acc, i.e. the plus from the contact to the red wire and the media works, this could be done using a switch, say the one on the remote, and as for the fact that the media starts from the beginning, that really annoyed me and I think it's just to the canbus and it has nothing to do with the discharge of the battery, and I solved it by removing the red wire from the canbus and connecting the acc from the car to it. And my problem is that the canbus interferes with my remote ignition and I think it's due to the incompatible canbus of the Baago brand

Hi guys, I wish everyone a good day. I am using px5 4gb Ram 64gb memory ,Hal9k v5.2.0 Android 10 software for Peugeot 301. I bought a new frame for the unit This new generation frame has volume up and down, bt ,menu6 and frequency change keys. This framework is made for devices with topway processors.There are 4 connections that are required for its assembly. Acc ,ill ,gnd ve can tx .I made all the connections without errors, but the buttons did not work. I wonder if it is a problem caused by the fact that my unit is an mtch processor? I didn't say SWC, PANEL KEY STUDY and MTCDTOOLS, but I didn't get any results. What should I do?
[MTCD  Android Head Units Q&A] Anton TNT:
buttons must be programmed via car settings with unit dealers of this device (dealers of device give this config file/files to sellers of device who gives this at end buyers if some mistake happens or lose settings).

Button config file can be programmed also via advanced settings (somewhere in that menu I have seen settings for it), import file or set.
[MTCD  Android Head Units Q&A] tebukan:

Hello I have a question... I have XTRONS DQS112L Android 11 based head unit and I would like to connect it to my car (Lancia Delta) CAN bus network.

[MTCD  Android Head Units Q&A] Pachis83:
For your info, I have an Alfa Romeo 159 with a PX5 XRC universal unit (no touch buttons). I have been able to mod the can-bus adapter from the specific KGL unit for my car and it's working ok.

I only had to re-arrange the unit connector pinout, respecting the original schema for my unit, and setting the right canbus box model type in the factory settings.

I can see in the 2din the outside temp, opened door info and, 12V signal for turning on the unit and steering wheel buttons. The only issue is that the canbus box implementation for my car is not as complete as for example in the VW cars, it doesn't show aircon info or rear view camera dynamic lines.

Regards.
[MTCD  Android Head Units Q&A] typos1:
Great work, can you tell me how you did it ? I so have an Alfa.

Yes, Ws are supported most, I dont think it matters not showing aircon info - the aircon controls are just a few cm below the headunit !
[MTCD  Android Head Units Q&A] Pachis83:
Yes, aircon info is not relevant, but rear view camera dynamic guidelines would be a nice improvement.

I bought the canbus box from a seller who sells the specific unit for Alfa 159. I told him mine was broken and he sold me the spare.

Before buying you must get the specific unit schematic for the connection harness, specially the legend on the unit itself where each pin is assigned to one function (RR speaker+, FR speaker+, 12V ignition, GND, etc...).

You will receive the canbus box attached to the specific connection harness, so you have to compare the original harness schematics for your unit against the new one and re-arrange connections as needed (preserving your unit's schematic of course). You will see that all units have Can+ and Can- (or Can A and Can B, I don't remember), those pins are where the canbus box connects to the radio.
[MTCD  Android Head Units Q&A] typos1:
Ok, thanks, can you upload photos of your schematics ?
[MTCD  Android Head Units Q&A] Pachis83:
I didn't save them. Anyway you can go ahead without schematics:

There are two groups of cables: the ISO connector ones and the canbus box ones.

The cables regarding the ISO connector is as simply as comparing the two wiring harness. For example for GND pin in ISO connector, you have to check that ends in the same pin in the unit connector. Most probably these cables will need a complete re-arrangement. Search for Alfa 159 ISO connector schematics on google and compare against the schematic wich is on the unit itself regarding the connector, you have to match all (GND->GND, RR speaker->RR speaker, etc...).

Regarding canbus cables, you will need a voltage tester. The box will have more or less the following cables:

Power supply and GND, for powering the box. You will differente them because are tied to +12V and GND pins in ISO connector. These two cables won't need any modification.

Canbus cables to the ISO connector, for "talking" with the car. These cables won't need any modification.

Ignition signaling. You can identify this cable by testing it with the voltage meter. You will get 12V when ignition turns on. Double check it's connected to the Ignition pin in the unit connector.

Lights signaling. You can idenfity it by testing with the voltage meter. You will get 12V when low beam is on. Double check it's connected to the light signalig pin in the unit connector.

Can A and Can B, bus connection from the box to the unit. Make sure they are connected to the proper pins in the unit connector.

In this way the specific unit schematics are not needed. I made the mod without them.

[MTCD  Android Head Units Q&A] Pachis83:
Is it a MTCB/D/E unit? Type?

Most probably CAN lines would be two pins from the ones marked as "NC", but it depends on the manufacturer. My unit it's an XRC and has them marked.

[MTCD  Android Head Units Q&A] totynho:
Is MTCD with LM MCU. In android, I can see CanBus apk in running applications, but I really don't understand how can I discovery where are CAN wires... I got in touch with Pumpkin manufacturer to try discover something, (https://www.autopumpkin.com/pumpkin...i-obd-rear-camera-steering-wheel-control.html is the same model of my headunit), and they don't understand what I'm wanting... They recommend a Connects2 CANBOX to use steering wheel commands, but about others canbus features, they don't know.
[MTCD  Android Head Units Q&A] Pachis83:
Maybe you can open the unit and trace the pins marked as 'NC'. If you are lucky all of them will end in the connector itself (no connection to anything) except two.

Another solution would be to find a schematics from the manufacturer. Try to search for LM schematics, pumpkin is only a distributor/seller.

Anyway... what car do you have? Are you sure you will get any improvement using "native" canbus support instead of a connects2 canbus to resistive controls?

Regards.
[MTCD  Android Head Units Q&A] totynho:
It's a Peugeot 307, I want the native CANBus for other functions than just steering wheel control ... In Brazil, different devices from the original never get an integration with the CAN network, the installation professionals here do not have enough knowledge about CAN network, at least most of them I've tried, some of them forgot the tools inside of the panel ... It is impossible that they can implement a CANBUS installation. It's very complicated get support here, lol.
