I am struggling with getting swc on my android install. Since I am installing this in a Maserati there er no available can bus swc unit to buy. I have read out the cantus on the Maserati so I know the code for each switch, but I have not been able to get information on how the input on the head unit (joying auto) there are to pin on the main connector dedicated for the swc but I believe it is a 2 way serial transmission. I measure 3.3V on both but one in with a weak pull up so it must be the rx input and the other to. But what baud rate and protocol? Can anybody help me with this.
Will it also be possible to transmit the radio station info to the cars dash display via this output.

I'm also looking for information on the baud rate and protocol. Did you find anything?
Android upgrade.

Yes and NO. The andriod radio that I was trying to communicate with was modified (by the supplier) so that the SWC input was changed to a serial communication. Normal is Resistive or voltage input.
When I was told what to modify to get the radio back to standard SWC, then I was able to control the the radio with a DAC output on my can-module, but this limits the functions to only standard SWC functions. The radio did have apps that could get information from the car like fuel consumption, trip control ect. But the supplier would not give me the protocol for the serial com. So I was not able to make the can translation for the Maserati.
So if I want to have these features then I need to reverse engineer it.
The radio supplier did supply a Can converter that fits a Citroen, so I will need to make the install on the Citroen and then read out all the serial data that the can converter makes in use. And that is not a task that I want to spend time on now that I have got the radio to work with the SWC.

Thanks for the info, really curios to know that the design allows for both analog and digital control with the proper changes.
Regarding the can converter, are you in Europe (I'm going to guess you are as you mention Maserati and Citroen ) and willing to sell the converter? I'm looking to buy one to test and debug so I can find out how the information is sent to the head unit.

If you want to analyze the serial transmission between the andriod radio and the can-converter, then I suggest that you order a headunit and the additional can-bus module for a Citroen C5. Go to www.Joyingauto.com
They sell this Android radio with additional features that link climate display. see link https://www.youtube.com/watch?v=X40sgh1lxao
BTW they also have these unit for VW with the same features.

Thanks for the info, I already have the HU and so does my friend. I've made some progress in my thread so I will keep trying to find a solution!

Hello all,
I have a KGL1, 1024x600 RK3188 unit and even if the controls in the steering wheel work propperly, I am missing the part of the "FIS" screen (I have a SEAT-VW car group) where I could see radio stations and song titles.
After I installed this navi-radio, the screen became completely black and is not showing that information anymore, that was previously shown with the original "standard" radio that came with the car.
Do you know if is it there any solution for this? or it will be always like this?
I attach a photo as an example from other car (the part of the yellow square), but the result is the same.
Thank you.
hello,
i think this is normal.
i have a vw too, and my FIS after installing a "non OEM Radio" only show me the same information.
my opinion is, the can-bus adapter can only read information from the car, there can´t write back or send information from the new "non OEM radio" to the FIS.
greets
I have an Audi with a similar display on the dashboard and I get some information displayed. There is a CAN BUS decoder installed in the wiring loom that I believe is supposed to be a two-way thing - i.e. you change the volume, track or radio station with the buttons on the steering wheel and these are interpreted by the head unit or change them on the head unit and they are 'supposed' to be sent to the cars computer. This partially works on my Audi, although the text that is displayed is wrong or interpreted wrong; only the Radio band and frequency are correct. I think the CAN BUS unit 'tells' the car what is happening (i.e. its a music track or its a phone call), however I think the car is expecting some more information regarding the details - i.e. PHONE + Number or Contact name, or USB Audio + Track number/details.
I think this is down to the software on the CAN BUS unit - but I am still learning.... I haven't seen any details of updating software/firmware on the CAN BUS adapters?
Andy
Thanks a lot to both of you.
@ADB100, how did you managed to make it working? For me in the upper part of the FIS, nothing appears and if it could see the radio station, something is something

I didn't do anything other than install the head unit with the CAN BUS decoder already in the wiring loom. I previously had an Audi RNS-E unit installed and all the information in the DIS (Audi refer to it as the Driver Information System) worked - Radio Station, Phone Contact, SD Card track name. The wiring loom that was supplied had the quadlock to connect to the connector from the car and then a small connected to connect to the back of the head unit. There were then RCA's for the four audio channels (FL, FR, RL & RR) plus the CAN BUS box. The CAN BUS box had a label on it saying 'CAN BUS DECODER. For Audi A3/TT' and then a software version. Its all installed in the car now so I can't tell you exactly as I'd need to remove it. I should have probably taken a few more photo's before I installed it... It might be coming out anyway and the RNS-E going back in to be honest as I am not too happy with this Tonghai Create unit...

Some HU "write" on the FIS, and others not......mine don't, but Xtrons PF73AA3A do.....
I am considering installing a Joying Head unit in a BMW 118i 2008 car and know that interfaces are required to integrate Bluetooth and steering wheel controls, however after much research I can't any information about replacing the existing BMW Professional radio/CD unit which has a MOST bus fibre optic connection which communicates with other modules in the audio system.
Has anyone done a similar conversion and knows what is required to ensure that some existing features, such as parking sensor system, are retained?

Have you asked joying? [email protected]
(Make your mail simple as their English is not too good.)
I assume you also checked the BMW page on their site? It doesn't seem to mention a 118i
Thanks for that surfer63. Yes I have looked at the BMW page and also been in touch with Joying using the [email protected] address. I did get some advice from them, but it was a bit lacking in technical content. I will try the address you gave to see if I get a different response.
Since my original post I have checked out what I've actually got on the car using diagnostic software and the MOST fibre optic bus is only connected between the head unit and the CD Changer at the rear of the car. So as I'm not bothered about keeping the CD Changer I can probably bypass the MOST bus.
There are lots of interfaces on the market for after market head unit integration; most are quite expensive and don't go into much detail of how they work. What I would like to do is get relevant circuit diagram information, buy the separate parts and make up my own interface(s). So if anyone would like to share appropriate information or links in this respect I would be most grateful.
Hello. guys
i got hold of a TPMS kit from Teyes. 4 tpms in tyre sensors, and usb reciver device with usb. i also got the Teyes cc2plus head unit.
My problem is that i have to sets of tyres. Winter/summer. So teyes or other brands that supports android 10. only ship with one set of 4 sensors.
I Have a Autel MaxiTPMS TS508 unit. I tried to read the sensor but faild to read. As i know the sensor is on 433mhz. and like other china products no markings or numbers.
I would think it was a easy job to just read the sensor and wright to a new one. so then you would have 2 duplicate sets. but no.
I am hoping some of you have the knowledge to help me.

What about the teyes thread that discusses your unit. You have to put some effort in on xda, there are no guys
First contact for support is Teyes, what did they suggest you do before returning defective product
I'd like to read my factory(!) TPMS sensors with my android head unit. Since OBD2 dongles don't seem to provide TPMS data (shame...), I think buying an aftermarket TPMS set, solely for the USB receiver unit. Since I can read TPMS data using my RTL-SDR dongle from my PC with no problem, it may be working, just a question of configuration.
And yes, "question of configuration". Did anyone around here have experiments / experience with such an USB receiver unit? Or am I just overcomplicating things?
@hurjup
Check the CAN settings in your unit. The OEM TPMS data are provided via CAN.
Depends on the car if the CAN box is able to translate these data to be able to see that in your radio.

Could you explain a bit "can box"?
For the very same(?) head units sometimes an additional box (can box?) was provided and sometimes not. Amyway, I didn't receive anything like that for my suzuki s-cross, which looks normal to me. Is it embedded into the unit (which doesn't implement TPMS reading)? Or is it not needed for general functionality?
In short, knowing my car type, can I improve the situation with TPMS, or it is better just let it go?
Thank you in advance...
Well...
I don´t know if your unit has an internal CAN-Box or not. Please ask your reseller.
Nevertheless:
Even your suzuki s-cross should provide these data via CAN.
So possible issues could be:
No CAN-box internal or external (but I expect to get clamp 15, Reverse gear and some other stuff to be provided by any can box)
CAN settings in the unit are wrong
Wrong car set
wrong CAN box set
But most of the time you run into the issue that the CAN box (internal or external) does not translate these data. (most of the cars are not supported for data more than SW-Buttons, Clamp 15, Reverse gear, e-brake)
You should contact your reseller and ask if there is a CAN Adapter available which decodes these data for your car.
I searched already, but did not find any for your car which should be able to do what you want.
I vote for the "CAN box does not translate these data" option. I've contacted my seller, but expect multiple rounds when it tries to google translate "can type" or "can adapter" before hitting a dead end. I don't expect any resolution of this problem through support, simply because the product page wanted to sell me an aftermarket TPMS set for my particular car type.
Some time possibly I'll make a try with such a set, maybe an app dev was lazy enough to adapt rtl_433 with minimal modifications and it will just work.
You´re not allone...
For my Mitsubishi I even don´t get the door open messages and climate control through the CAN box.
Even intire OEM TPMS is not visible. Just visible in the cluster. It is available on CAN, but not translated.
If you would own a VW Golf as example, you would get all this stuff on your unit....so guess why no one get´s on the CAN traces and translates the signals for cars which are not sold that often...
Hello,
I would like to understand more about the canbus box, hope someone could share some knowledge.
I see the models for sell and is like, model 1 is for 3 cars of the Y brand, other is model 2 is for 10 cars for brand X brand and so on... And if i check for example RZN vs HiWorld is almost the same car list.
I think the data the canbus have is not specific to the type of car, but for the can version of the car correct?
So, if a box have information for the Sylphy and for the Tiida, i can select any of these in the car select of the car?
I ask this because i have a sentra/sylphy, my box is Raise and my unit have sylphy only on the hiworld box, i use X-Trail in Raise and i have the basic working fine, dash TFT with radio infos, clock etc... But the new unit that i don´t install yet, don´t have sylphy/sentra in any place (i already ask a update for the vendor).
Another question related but not so much, these boxes make the 6v for the backup camera too? My current box use a exterior 12v - 6v converter, but the new one don´t have any of these, only the box.
Thanks for all the replies!

I have seen both types, one where the 6V came out of the Canbus decoder directly to the camera and another Canbus decoder from the same maker where that same wire went into a 12V/6V converter before feeding the camera. Suggest you probe the camera voltage feed wire before trying to connect the camera, I did on the first Canbus decoder and found 6V.
Indeed, after i read your message i check the Upindo vendor in aliexpress, he share the pins layout, and i compare some boxes there, not only some have 6v output but some have 16pins and others 20pins.
Hi folks. i hope someone can help here. I have just fitted a JunSun 825x_pro (I can add more info if it's needed but it seems to be the VI model with 2gb and 32gb) to my 2014 Peugeot 208 1.4HDi. It's working fine (Even the 4g connection with a sim works) apart from one thing. I cannot find the correct canbus code for it. I have been through the list and tried everything that says Peugeot (and PSA, but nothing shows 208) to no avail. I am beginning to suspect I have either got the wrong canbus decoder or the wiring is wrong since everything else seems to be working correctly. It's kind of important to have the steering whell controls working.
I don't want to rip it all out again unless I really have to.
If anyone has any suggestions I would be grateful.

You could check if your car exposes the SWC as resistance matrix to the OEM harness. In this case it's best practice to bypass the CAN box for SWC because the learning function can be used and you don't have to live with hard coded mapping of key and function.
You may try to find the pinout of your original radio via Google by using model number/name of the OEM radio.

I might just have to do this, although that would be a steep learning curve!! The stereo has learning functions and I can remap the keys (once I can get them to register). I need to wait until the trim pry set arrives since the new unit is really tight and I don't want to damage it with screwdrivers etc. I can then get the canbus decoder out and see if it has anything on it to identify it in the system such as a model or anything. I also need to ensure the plug is in the right way round into the socket in the back of the unit -it has 2 wires on one end and I think the plug can go in either way!! :-(
Doh! Never mind. Important note: always check you have the connectors in the right sockets!! had the 8 pin canbus plug into a 10 pin - not connected - socket. :-(
[edit]
Even the car trip button is working now a la Peugeot head unit...
