Probably with my decoder by LXH (setup name LZ in the radio,for BMW car) 16 pin connector,see picture, the 2 Can pins are ok, but it seems strange to me that in the "Forward" screen I VERY rarely have data strings, while in the "Receive" screen they are constantly updated. ..

also with the new OTA Canbus firmware from a week ago, I can no longer make a settings for AC climatic control (even if before the Can firmware update this utility didn't work anyway, it never worked live, so...)
[Android Head-Units] kwiedo72:
That's strange, that's exactly the opposite of my car. In the receive screen I only see something when I press a button such as volume up or down and the forward screen is continuously updated
[Android Head-Units] MauriBixio:
Well, what can we say...everything is strange with these Chinese units!

Honestly, the behavior of you Can flows seems more correct to me rather than what I have, reversed.

But I'm curious to find out...

Edit:

did you reverse the 2 Can wires?
[Android Head-Units] kwiedo72:
I haven't swapped rx and tx, but I don't think it would be a bad idea if you did. If the receive and forward screens show what is being monitored on the rx and tx wires, then it even seems logical to me, everything works in my car and nothing in yours
[Android Head-Units] kwiedo72:
With the original wiring and canbus decoder that came with the unit, nothing worked, I didn't even have any sound. Because Hizpo was anything but helpful, I bought another wiring harness and Canbus decoder, now everything works, but I only have OBD2 error codes U0184 and U0163
[Android Head-Units] MauriBixio:
I think you're right, logic leads you to think like this... I'll try to reverse TX to RX and see what happens!
[Android Head-Units] ScorpionSX:
In my car, with correctly connected Hiworld canbus I have lot of information in the Receive box and in Forward is only something which I indicate - steering wheel control, etc...I didn't test it with Raise box, I just put the stereo back to the car and it's freezing out, I'm not going there again now :D

But I have a Hiworld and also SimpleSoft boxes already on the way from CN, so I will report again when they arrive. (I ordered the Hiworld too, because I suspect that my box may have a bit broken connector or some of it's pins :( )
[Android Head-Units] MauriBixio:
In my case, it seems strange that have a continuous Can data flow in "Receive" (like you) and almost nothing vice versa in "Forward"...

For example, if you click on any button on the steering wheel, everything always works ok (EVERY button/function is ok, and these buttons definitely work via canbus) but I DO NOT see the canbus data change to "Forward" by acting on any button... mysteries Chinese! :D

However, I use a decoder/brand (arrived with the S8) that very few have here (only for BMW cars I presume) so I have no feedback from other users on the behavior of this.
[Android Head-Units] Zlatko580:
@MauriBixio I also have LZ CanBox, for Audi A3/A4, got it from HIZPO with S8 unit.

When I installed headunit, I wasnt able to turn it on without CanBox (forget to connect), so I assume that my wiring of TX/RX wires are correct. Also have working SWC, reverse camera, and some basic display of text on instrument cluster, that is what bother me most.

As shown in attached pictures, when default radio is active, instrument cluster show RADIO and frequency, when I open BT app, it show BLUETOOTH... When I open some other app, for example YT Music it show some strange text C >> .t. Default Audi radio, has more detailed info on instrument cluster, radio station name, song name, if using bluetooth for calling it display numbers etc.

I have continous flow of data in RECEIVE, in FORWARD only if press button. I think that is because CAN gateway of car is trying to communicate with radio, but has no response (or response is not what he want to hear), then it store a fault, radio is not reachable.
[Android Head-Units] kwiedo72:
The more I think about it the more unclear it becomes. My car is a ford f150 with bsj canbox on hizpo s8 unit. Everything in my car goes via canbus and seems to work with the s8 unit.

In your BMW the SWC also works via CANbus, which also work correctly, and yet we have opposite results with regard to RX and TX. I think that the different brands of these can boxes interpret the terms receive and forward differently. The constant data stream is probably ALL messages sent on the canbus network, including those not intended for the s8 unit and the s8 only responds to relevant messages. So in your case the data stream is received by the s8 while in my case the data stream is forwarded by the network. That's the only logic I can make of it
[Android Head-Units] kwiedo72:
Should I connect TX to RX?

As such, serial devices should have two serial pins: the receiver, RX, and the transmitter, TX. It's important to note that those RX and TX labels are with respect to the device itself. So the RX from one device should go to the TX of the other, and vice-versa.
[Android Head-Units] MauriBixio:
Well,all the suppositions of the guys in the last few posts are acceptable,probably each decoder/brand acts differently relative to the car/brand in which it is used,and perhaps for this reason we have opposite CAN data flows between "Receive" and "Forward".

It is also true that serial transmission occurs in "reverse" mode,i.e. TX to RX and vice versa.

I asked Hizpo if they know the pinout/functions of the decoder by LXH (16 pin connector) for BMW (which I also read Audi uses,thanks to the guy for his feedback,actually if someone else uses this type of LXH decoder with BMW it would be very you feedback is useful) let's see what Hizpo responds (but I doubt they know anything about this).

We continue to investigate this mysterious use of Canbus with Sx units, in the end we know much more in this thread than the sellers of these Sx units! :D

Hi, I bought My head unit in version S7 from hizpo from this link:

Do You know how delete this widget with robot? I can't find the option.
[Android Head-Units] ScorpionSX:
This is very similar as my situation with Ford. The original radio can display the station name in the cluster, Android only shows frequency. And so on...

And the same thing is with RECEIVE/FORWARD, in my case with Hiworld box, as I said before.

I think we might be able to get some more stuff to show up on the cluster screens, maybe even get the same functionality as OEM radios, but to be honest, it is beyond my abilities to search through the code of the Android apps and CAN messages. That being said, I do however have a current Dynavin firmware and also MCU I think, where we know that it's possible to get this information displayed correctly on the cluster with the headunits for VW group cars. If someone would be interested in investigating it, I'm happy to upload it somewhere and share a link ;)
[Android Head-Units] Peixeiro:
I have an Ossuret S4, ona Peugeot 407. The only thing that doesn't work and I think it would be important are the car's errors. When I open a door or the trunk, a popup appears with a drawing of a car with the door(s) open, but if a light bulb breaks or a tire gets a puncture or any other error, nothing appears on the Android radio. Just the symbol on the small quadrant screen.

Any solution for this???

Answer by Hizpo to find out the pin/functions of the connector (16 pin) on board of my BMW canbus decoder by LXH:

"Hello, friend, you don't have to struggle with this. Connect the radio correctly with our cable and it will work normally"

As I suspected...they never know anything about what they are selling! :D

EDIT:

I'm almost tempted (to test) to buy this decoder by HIWORLD for BMW (decoder ONLY, no cable) it seems to have 16pin like my current one, and it also seems that the wires are identical... someone who has HIWORLD confirms that the connector has 16 pins?

https://it.aliexpress.com/item/1005003777713675.html?spm=a2g0o.cart.0.0.338418fcklXH6p&mp=1&gatewayAdapt=glo2ita
[Android Head-Units] kwiedo72:
Skyframe is the same seller where I bought my new canbox. I gave them all the specifications of my car and asked which box and wiring was most suitable for my car. They suggested something different than what I had in mind, I bought what they suggested and everything worked. So maybe they know what they are doing, or I just got lucky.
[Android Head-Units] MauriBixio:
I'm writing to them...thank you.
[Android Head-Units] ScorpionSX:
My guess is that it's this box that you're buying: https://v3.olx.ba/artikal/57719771 - it's a 20pin box/cable. I would rather order the whole thing, just in case ;)

//EDIT: here's some information from Hiworld if you care for a little chinese lesson :D https://mp.weixin.qq.com/s?__biz=Mz...de78101f53680d6dfacd&scene=19#wechat_redirect
[Android Head-Units] MauriBixio:
The Ali seller I highlighted writes:

16Pin Car Wiring Harness Android Radio Power Cable Canbus Box Decoder For BMW 3 Series E90 E91 E92 M3 X1 E84 BM03.10

so it should be 16 pins,but I wrote to him if it is "plug and play" with my current 16 pin decoder, I'll see what he will reply.

The complete "main" cable I checked is like my current one, same pinouts/wires/positions so "useless" to buy another one.

However, I must FIRST check if brand HIWORLD with the canbus settings of the S8 radio can manage my BMW car!

I'll check tomorrow...

Chinese link HIWORLD...I'll look there tomorrow. ;)
[Android Head-Units] MauriBixio:
Alternatively, for BMW there is also this (16 pin)

https://it.aliexpress.com/item/1005004701778046.html?spm=a2g0o.cart.0.0.297d18fcl1o02k&mp=1&gatewayAdapt=glo2ita

but I don't know the brand, and then how to set the radio setup in the canbus...
[Android Head-Units] MauriBixio:
Definitely...I think you are right, the Hiworld BM03 canbus box has 20 pins (I have seen many images/info on the web about this) probably therefore the seller Ali's advert, where he writes 16 pins, refers to the MAIN connector and not to that of the decoder!

The Chinese are often unclear in their sales.
[Android Head-Units] ScorpionSX:
Yes yes, the 16pin refers to the main stereo connector, not the canbus box, that one is most certainly 20pin from what I could see on some "real" photos. I remember that I also saw 16 pin canbus boxes, but it was some time ago, maybe some older revision...? (But they were for Fords, as I was checking out those, not sure about other brands)

If you click on one of the two links on the chinese Hiworld website, near the information about your box version, it will get you to a PDF with the pinout for the box, you can then verify which wire goes where and if it's correctly done on the wiring.
[Android Head-Units] ScorpionSX:
And btw, I know I saw somewhere the "design" of that sticker on your LZ (LXH) box...these were sold with Ford stereos some time ago...I never knew what brand they are, I even opened the box and there is no indication on them...and in the stereo setup, under LZ (or LXH) there is no Ford Mondeo/Focus...this box does work, but it only supports very basic stuff, like steering wheel controls and backup camera control. Nothing else. The harness for it comes without those two pins for TX/RX and I don't know which pins it would actually use for this, if it's even capable of this communication.
[Android Head-Units] MauriBixio:
The "old" LZ canbox for BMW (pre 2020) did not have the 2 wires for TX and RX canbus (I remember I had one with one of my previous Erisin radios) but the steering wheel controls still worked (certainly via canbus) and moreover I had info on fuel consumption elsewhere, but NEVER AC climatic control working).

How these things could work without the 2 additional TX and RX wires I don't know...

In the new current Canbus decoder coming with S8, by LZ, there are obviously also the 2 TX and RX wires, but I DO NOT have any information on consumption (which I had with the old Erisin radio and the old LZ decoder), no MP3 data in the cluster, and not even AC climatic control working... I think this one by LZ is really a "basic decoder" canbus.

In both canboxes (old without 2 wires and new) I have the BMW oem parking sensors working with colored bar animation on the display, with active reverse gear. All this is certainly via canbus.

The canboxes by LZ are all with 16 pin connector, with schematic wires of the canbox it is relatively simple if necessary to rewire the wires of a 20 pin canbox (e.g. HIWORLD) to 16 pin connector (by LZ) the number and inputs wire are the same, only the positions in the pins of the canbox connector change. The 16-pin main power connector is identical, and the wires/inputs for both, HIWORLD vs LZ, are identical.
[Android Head-Units] fumbreisa:
Hi.

Just to tell you, in case it helps, that you are in the same case as I say here., and precisely that decoder is the "worst" of the two that I mentioned. It's a Simple Soft XP.

Like you, the SWC works, but little else. However, a HiWorld shows much more info.

From what I have read, I suppose that @chadoe is not wrong and I the connectors of both decoders do not have the same 16 pins.

I'm boring the seller to send me the schematic because I'm not able to find it anywhere.

Thank you all for the comments you are making. I keep reading you.

Cheers!

New update for Simple canbus.

Some extra tiles are added, but probably all of them inactive, in my case: CD play, Amp Info, Drive Mode, Panel Control, TPMS info, Compass, Radio and Time
[Android Head-Units] ScorpionSX:
Yeah, I posted this few days ago (maybe in the Firmware thread), but it's an update for the app, not the box itself. Also not much changed for me, most of the tiles that I have in the app are inactive...and even from the active ones, not a lot of stuff is working
[Android Head-Units] mobilefanatics:
Hi guys, I have an Ossuret S5, which works great with only one annoying problem: after 30 minutes of using Android Auto with my phone, zlink keeps disconnecting, and then reconnecting randomly. I have updated my head unit, my phone, and tried different versions of zlink and aa, tried different cables but the problem is the same. Has anyone had the same problem? Do you have any idea what could cause this?
[Android Head-Units] MauriBixio:
My idea:

I think that CarApp will be updated over time, via OTA, but if the firmware inside the canbus decoder chip doesn't do the same (and this is impossible via OTA or USB pen drive) nothing will probably change... but I hope I'm wrong! :D
[Android Head-Units] ScorpionSX:
I think you're actually correct here...the APP is one thing, maybe for some cars it actually can control some stuff (for example with Raise box I can control if I want to see door open/close and sync time in the cluster with radio, but that's pretty much it...and some climate stuff probably, but with manual A/C, I don't see that) - but, the box is a different thing...that I believe can be updated OTA as well, but no one seems to bother with that...? I know for a fact that there is a newer Hiworld box (currently also en route to me) but the app won't offer me to update the box FW. Same with Raise and Simplesoft (XP).

So maybe in the future...? We can at least hope...we came a long way where we now have actual updates, even OTA for these chinese units, so maybe this could be the next step...
[Android Head-Units] ScorpionSX:
So maybe I gave the Hiworld box too much praise. I was testing another stereo in the car also because some canbus stuff and then I put my S5 back with Hiworld box connected. I quickly wanted to test everything, so I just turned on the key to position 1 to turn on the radio and I again got a message in the cluster "AUX heater on" ... which to me indicates some bug in the canbus communication. Or I don't know...car isn't throwing any codes, so that's good and this is probably nothing, I can even turn off the messages about the Aux heater, so maybe it will disappear completely, but it just bugs me.

I wrote previously that I have two more boxes on the way, one Hiworld with newer FW and also one SimpleSoft. I will test those out to see if they are behaving better.

(sometimes I just want to give up, make a straight connection to the radio and be done with it...what's so important that I would miss it?)
[Android Head-Units] kwiedo72:
The simplesoft box that came with the unit was completely worthless for my car. The new one from BSJ covers almost the entire functionality of my car. Since then, the car app has had many more options without an update, but not all those functions work

I bought an Hizpo S5 and installed on my car Passat B7 a month ago. I received HU with

System version: QF01.20230824.202940_v2.69_02

MCU version: QF03.V01.05.20230617.002121

For some BT calls issue I writen to Hizpo and two days ago they sent me new files and ask me to update MCU and system. Now I have

System version: QF01.20231110.185622_v2.84_02

MCU version: QF03.V01.06.20230814.002121

I supose those are curent files on autofather.

After MCU update (I done this first and I check some functionalyties before system update):

- vol+/vol- buttons on steering wheel are moore responsive than before, now works as should be, initially I was thinking is the buttons itself issue

- open doors prompter besides the car image, now have and text writing which door is opening,

- I have moore tiles in Car app, now 13 instead of 4 before, but most of them inactive. Maybe tpms works with OEM sensors, but for the moment I can't check, I have winter wheels without sensors installed on car.

CAN bus box is Simple soft.
[Android Head-Units] Vampire_Dracula:
I tried to replace my Simple canbus box with a Raise canbus box. The label si specifying its compatibility with my 2019 Honda CRV EX-L, and the harness matched my car connectors (well not all of them can be used).

The intention was to see if I can get the media metadata displayed in my instrument cluster together with the navigation guidance.

Nope, no change from this point of view. Not working. Actually, even without any canbus box my instrument cluster has the same tiles, including the two empty slots where this info used to be with the OEM headunit.

I was also hoping for a better compatibility with the climate controls (since not all functions are properly synchronized between the hard buttons and the display)

No change from this point of view: the behavior is identical between the two boxes.

But the Raise canbus seems to be worse for my Honda. I was not able to make the backup camera work (the forward camera was Ok), and I didn't get the open door alerts on the screen anymore.

So I went back to the Simple canbus, and gave up on this idea.
[Android Head-Units] ScorpionSX:
One more thought about these canbus boxes and their communication with the radio and the car.

When I take Dynavin as an example of the "best" intergration (yes, mostly just with VW cars), I believe it should be possible to get the same thing from our units.

What I'm thinking is, take the radio app for example. In Dynavin, it can actually send the station name to the instrument cluster. With the K706 it can send the frequency. But the radio app also knows the station name, it can display it on the radio app. So, what needs to be done is, basically "only" change what the radio app sends to the car/canbus - not the frequency that is currently on with the radio chip, but the text that is displayed on the screen (that is either the frequency or the name). I know, easier said than done, but I honestly think this should be possible.

With the USB media playback - it can show track number, instead of the tag from the MP3 file. So again, it "knows" that there is a music file and how far along is it in the playlist. So it should be also possible to forward the track name, instead of the track number. Dynavin does this. It somehow "knows" what is the track that's playing - so I believe the app can actually recognize it and send it forward to the car/canbus. Same goes for ZLINK and even the navigation - at least their Dynaway app can probably send these informations to the car.

I somewhat doubt that the chinese developers will actually get to do this anytime soon, they're probably mostly busy now faking Android 13/14 on these units :D ... but if someone would be willing to look at this - I can provide the current Dynavin D8 firmware, where I guess you can decompile their apps and take a look at the code - that is unfortunately beyond my skills. Please write me a PM if you like to give it a try.

Hi! As I know the HU supports both wired and wireless CarPlay in the zlink app, but only the wireless connection seems to work. When I connect it via cable, nothing happens.

Has anyone managed to get wired CarPlay to work?
