Hi,

How you got this to work, mean is it BT and wifi connected...because I can't figure out yet how to make this work that my unit using my cellular internet data connection and make phonecalls.

On my Samsung phone Android Auto spinning around searching, have to make seperate wifi hotspot connection and BT connection to have internet and making phonecalls on my unit....Carletter shows connected where I can choose Android auto or wifi I believe and shows screen "and now install Carletter on your phone"....but how?...what do I miss, do I need Carletter app on my phone.....can't find it anywhere when i google it??

Actually don't wanna use Android Auto, just that my phone wireless automatically connects internet and that I can make phonecalls.
[Android Head-Units] blue_one:
You have to use the "phone" app on the head unit to establish the Bluetooth connection to your cell phone. Than it will use it for calls. No need for the carletter app. That's only for android auto.

The hotspot connection is a different matter. You can use tasker to start the hotspot on your phone every time it connects to the head unit via Bluetooth. And you have to save the Wi-Fi settings in the head unit ofc.
[Android Head-Units] Meteordust:
Okay thanks....(y), regarding BT phone I did the pairing from phone, but understand I need to do it the other way around.

And auto hotspot will be tricky indeed, thought there was a phone Carletter app.
[Android Head-Units] Clyde72:
I don't even use sleep mode (nor canbus, no SWC), system shuts fully off every time I leave the car and after full boot up I never had own apps crahing nor loss of system changes.

That works indeed but you need to know the release date. I retrieved 1019 fw that way because I knew that release existed...

How do you remap these buttons? Not found yet. Would like to remap to launch Google Assitant a.o.

Where in your car did you place the external mic? OEM mics are often hiding in the head liners, death places, done so especially to stay away from interferences from wifi/bt/unit itself and vibrations in the dash while driving.
[Android Head-Units] Clyde72:
I read elsewhere that it activates itself if you turn on wifi and reboot and then open Zlink
[Android Head-Units] Meteordust:
Sleepmode is handful in my opinion when you put gas in the car, shopping etc, so no need for a full unit off and fresh start.

And indeed after a fresh off start I also never had a problem, only with sleepmode, so have it on 2 hours now and see what it does with all the apps whitelisted (factory 8888).

You don't need to know; just check every few days changing the date in the https link from 230109 to 230110 and so on ;), but understand there is now an OTA update after some version, reeded that on this thread. But also don't want to upgrade every few days with clear user data.

Remapped my plastic buttons because they didn't work anymore after full factory reset, can be set back in factory 8888, learning buttons. this is on my unit, menu, return, nav, bt and so on..no remap for Google ass.

Putted mic in door post (A Pillar) on head hight so around 30 cm from my head, no interferences in my car.
[Android Head-Units] DCB103:
Any one using Agama car launcher on his unit ?
[Android Head-Units] DCB103:
For the people of GA, have you turned on the hey google feature in settings of GA so you do not have to press a button any more
[Android Head-Units] nyp42:
I have tested many launchers including Agama. Ultimately went with Vivid launcher. Correct me if I'm wrong but I think Vivid was devoloped right here by the XDA community (or at least a person from this community).
[Android Head-Units] nyp42:
Please don't use the Firmware thread for discussion or comments regrading firmware. Please quote the message in question on this thread and we can discuss it here. I don't want the Firmware thread to turn into 20-30 pages of discussion with Firmware post mixed in every 5 or 6 pages that you have go searching through.

I am pretty sure that is the firmware that I currently have loaded and it worked fine for me.

Can anyone else confirm or deny if the link to 20230109 firmware does in fact load firmware from around 22030109? Often the date in the firmware version and the date in link are off by a day or two.
[Android Head-Units] Clyde72:
Will test it 2morrow or friday but I am sceptical and thats why I said I gonna wait for the next major update some days ago
[Android Head-Units] Clyde72:
I did but Voice Activation does not work, I think you need to keep the GA service running in the background for that. Not yet looked closer to do that...
[Android Head-Units] Clyde72:
I understand but the unit boots quick you know that is why I use it that way.

OTA doesn't work with any of us as far as I know, even not with 0104 fw

I never loose user data, there is an option so you can keep user data when updating

Aha, you can use the learning function for that. Thx. I thought it was for SWC which I do not have... and remapping the horn seemed futile to me 😅😉

Thought off that but I didn't want to dissassemble A pillar, running cable under my dash etc. Still not decided. Maybe I will put it in the headliner where the OEM VW mic is sitting...
[Android Head-Units] nyp42:
There is a Default Assistant setting and a Voice setting (or something like that) in Car Settings. Haven't played around too much with it but that might have something to do with it.
[Android Head-Units] Clyde72:
Since updating to 0104 fw AF (Alternatif Frequency) on FM seemed finally working. But it only worked stable for like 2-3 days... Yesterday evening suddenly FM began by it self running all over the frequencies without stopping. So I have dissabled AF again and FM works as before holding the selected frequency.
[Android Head-Units] Clyde72:
I tried these settings but Voice Activating GA doesn't work. And when you go to running services you will notice Toppal service runs in the background. GA is set as Default Assistant & Voice since weeks but you can also default Voice to Waze or whatever app installed that has voice functionality...

I even disabled Toppal service and did uninstall Toppal & Toppal Service but since 1216 update Toppal was back installed automatically. It didn't change the defaults fortunately.

Will try to get GA service to run in the background whenever I have a moment (without Tasker or so)
[Android Head-Units] AlphaRadioDog:
So the end of the saga is, the eBay merchant said " Because our technicians say that there is no lack of harness, because our products have been updated and listing has not been updated in time, sometimes it will be different. If you have tried according to the above instructions but the problem still exists, it may be that the machine is broken. You can choose to send the machine back and buy it again. sincerely" So I am going to send it back because it does work and because of the useful no support AND because I came into a small windfall and am going to go with this instead: https://carsoll.com/collections/new...h-unit-bluetooth-wi-fi?variant=31667010011201. Woot Woot looks like FUN!
[Android Head-Units] Meteordust:
Hi,

Thanks for the explonation...

Is there a way to do it for the second time, mean if you want to install another bootanimation.zip?, because I adjusted mine but not loading it for the second time.

Sorry, after I changed the file size by modifying/removing some parts it installed the new one.
[Android Head-Units] PrinceLc:
Right the Android Bluetooth menu is the right place to pair
[Android Head-Units] Maferto:
That happens to my screen too, I have read that changing the flex cable was solved but they tried to solve it and they did not change the cable, they put a few drops of screen glue on the flex connector, now we will see how to remove that glue that I think is not going to be easy...

Should I throw it away and buy another one?...
[Android Head-Units] delumiron:
You don't have to throw it away. Let's hope we can change. I'll wait for the seller's response first
[Android Head-Units] Maferto:
It's complicated, I don't buy the screen on any website, I install it in a workshop but it says that since I don't buy the full warranty, I must send the screen and pay the shipping and return costs from Spain to Asia and back, which I won't do, the problem is that he put the screen glue cable

In a nutshell, he told me that if he didn't spend more money, he couldn't do anything. I've already reported it
[Android Head-Units] PrinceLc:
They did this ?? Not good Hizpo or Ossuret ?
[Android Head-Units] Maferto:
Yes, they did that by putting a few drops of glue on the cable connector because they say the connector was broken.

Everything is complicated because it happened to me that the screen sometimes turned black, that since the installer lives 3 hours from my house, he tells me that he sends me a new screen to change it and tells me that it is easy to do it, but possibly something happened during the assembly and according to him, when putting the cable it got wrong, but I told him that if a screen is under warranty, the normal thing is that they would have picked it up and sent it to the technical service not do it, now he does not want to know anything about this. Let's imagine that the car breaks down and the workshop tells you that it sends you the parts and you put them on, it's easy.

This is something surreal so I see that I have to fix it just because according to him I didn't buy the extended warranty that is worth $400 more

I put you in context, this installer, which in TikTok has its channel criticizes many Aliexpress products and criticizes very negatively Junsun says that their screens are called Theallinstaller, when really sugn they have told me in the group of Junsun Spain they are Ossuret or Hizpo screen and what I think is that their screens are as Chinese as all, only that he buys them on Alibaba by quantities and with his car he goes where they call him to assemble them.

In the end, I see that I have to take the screen somewhere where they can change that cable, or keep it in the drawer of oblivion and buy one of the Teyes brand or another that you recommend to me.

Thank you for listening to me, I don't know what to do anymore.

Hello fellas,

I'm searching some help for the media from the link, because I struggle with the topics below already 5 monts.

First, as far as I understand the QF001 (K706) model has 2 desings. The one from the brochure, and the one like the original shape of the SONY RADIO for Ford. The media is mounted on Ford Mondeo MK4 2.0 TDCI

I bought mine from Hizpo Store in AliExpress. The first issue I faced was that the media didn't turn on. I wrote the the seller and he told me that I have to connect the yellow-orange wire with the blue one. ( Just like it is in the picture I've attached).

Okay, I did it however noticed that the media turned on once I connect the wires GIVEN THAT the kay was in ignition off.

I thought this is normall for the first connection and mounted the media. I tested the functions. Shared spot from my mobile, connected the radio antenna. Everything was working as intended. The only problem was that after ignition off the car, the media didn't off. I thought that the ECU is going to stop all consumers after some point of the time. I was waitng more than hour, but the media didn't turn off.

Wrote back to the seller, he sent me another canbus ( another brand different than "Hiworld" ) but using it - the media didn't turn on at all.

Then tried to swtich the model of the car trough the FACTORY menu of the media to FOCUS because one of my friends advised me check it this way, but unforunately it didn't work.

The next thing I did was to reset the factory settings. Not sure if after this or at some point of the other attepmts I did, but:

THE PHYSICAL BUTTONS have stopped working. ALSO the SOUND disappeard. There was no sound on every possible way:

Bluetooth, Radio, Youtube, Embedded songs.

I thought something was burnt.

Then started searching information about the buttons. I found that I have to "learn" them from the factory menu.

Did it and they started working again.

However I didn't find some specific adjustmend for the sound? Searched in the developer mode and the factory advanced menu?

HAS ANYONE OF YOU FACED A SIMILAR ISSUE:

1. With disappeard sound? Is it possible some setting to be wiped after factory resetting and to needs a specific adjustment? Or it's most likely something related to the sound's hardware is burn out?

2. What would be the reason the media to not turn off after ignition off the car? As far as I understand the canbus is the one that it is supposed to manage this process? Corrupted canbus?

Thanks in advance. I'm looking for your replies.

@PrinceLc, @nomad_fsoak: I was not able to find the Android BT menu on the firmware I am using (from November 11th 2023). Please let us all know how we can access it, because I can open regular Android Settings, but there is no BT under Connectivity and Communications (the place with mobile Internet and WiFi settings).
[Android Head-Units] 19vik:
1. if you have an external amplifier (Ford Mondeo is possible to have) and is connected ok, something is unchecked in audio settings after factory reset.

2. if you have a canbus box connected, you should have this connector disconnected, otherwise the radio will never turn off. Also should find that on installation manual.
[Android Head-Units] MauriBixio:
Glue???

A really stupid thing to do, meaningless, which certainly won't solve anything!
[Android Head-Units] PrinceLc:
Update the firmware to latest or enable dual Bluetooth in factory settings when it's already there when not then update to the 19th January
[Android Head-Units] PrinceLc:
Yes the screens are all from Alibaba so what to do now ? Good question. 400€ for extended warranty? That's a pain also I bought the unit from Ossuret Global Store AliExpress and they changed me also the unit by warranty send me the cable a new display and now a new double usb cable because it was faulty.
[Android Head-Units] Dimitar Dimitrov 94:
1. How do I can understnad if I have an external amplifier? For example - if I connect the original wiring harness ( the rectangle one ) to the original Sony radio - it works fine and THERE IS a sound.

2. I explicitly asked the seller and he told me that this connector SHOULD BE connected. If I disconnect it - the media is never launched. I tried all possible options: 1) to disconnect the connector, 2) to connect it to the other blue cable - the only way in which the media works is the one from the picture I sent

If you have some suggestion I'm open to hear it!

The Chinese is already starting to sell all S versions with DSP BU32107. And that's a step in the right direction!
[Android Head-Units] blank-:
Hello! Has anyone tried soldering on a 360 chip on the QF001? I think I would like to try, if I have any chances of making it work. Does anyone know if there could be any compatibility issues? Is it possible that the OS or MCU firmware would not work with it? Also, does anyone have any info on which chip I need? I found one on aliexpress that seems to be what I need, but I don't know if there are multiple versions of this chip or its firmware. Also, I found online a ribbon-connected version. I assume that wouldn't work for my device, but I though I would mention.

Can anyone say what my changes are? Is it worth trying, or am I just wasting my time?

Here are the links to the chips I found:

https://a.aliexpress.com/_EI53da9

https://a.aliexpress.com/_EHL4m1n

PS. I have an S8 unit from ossuret, ordered a couple of weeks ago and with the latest OS and MCU firmware.
[Android Head-Units] MauriBixio:
1) Take an HD photo of the mainboard PCB where it would be "hypothetically positioned", so as to check whether the pinout (the one in the first link) "could" correspond in number/pins to the mainboard (S5-S8).

2) WITHOUT having the datasheet/schematic/pinout of the chip on sale, 99% of the time you can't do anything...

3) even if after all this it was ok, we absolutely DO NOT know if there is support for 360 cameras in the firmware for Sx devices (and if I remember correctly, it didn't seem possible to me, but I remember it was said by the sellers that for the future it would be implemented...)

So, retrieve this information and then come back, then we can talk about it... on a technical level, if everything matches, soldering the chip to the mainboard is absolutely not a problem, but it's EVERYTHING else that must be compatible.
[Android Head-Units] blank-:
I'll take the unit out and apart the following days to replace the fan and then I'll check.

Regarding point 3, there are a lot of references in the menu to 360 cameras, so I think it does have some kind of baked-in support. Although it may be residual from other models that have it...
[Android Head-Units] MauriBixio:
360 support is currently "just written"...but not actually implemented via firmware.

Maybe in the future there will be, but obviously it will require a mainboard with a specific chip on board.

Mekede devices do not have the same mainboard PCB as Sx.

The 12 pin "B" connector should be in the 360 chip area (if I remember correctly) but I'm not sure if it is currently connected to the wires/pins on the mainboard...
[Android Head-Units] ScorpionSX:
Keep the connector connected as the seller told you. That's ok if you have canbus box connected - which you have. Also keep the Hiworld box with that original wiring that you got with it. The orange/red should connect to those two blue wires which then go to the canbus decoder box - I hope you have it like this.

Then, you have to go to the factory settings and setup the correct canbus decoder. There is a chance that you don't have this and that's why the unit will not turn off with key. Factory settings code is 8888 and canbus option is the first one right on top. You need to select Hiworld brand, then Ford, then Mondeo and then the year (I assume it will be 2007-2014, no matter if facelift or not). Then, it will go back to the main menu and personally I also like to reboot the unit - drag the notification bar down and there is a reboot option. After this setting, you should have it working after the stereo restarts. It should turn off correctly with key.

Also, another tip with the Hiworld canbus, there is a 8pin connector which goes from this main wiring to one of the white connectors on the stereo. It has only 2 wires in it. Switch those two wires between each other (use a small pin to pry it out of the connector) and then connect the plug again. You should then have some more information displayed on your instrument cluster screen from the radio.

If you got also another canbus from the seller, you can set up that one as well, but only if you got also its own wiring cable - I assume they sent you a "Raise" canbus - it uses different pin layout than Hiworld, so you need to change the main cable as well. And, of course set up the different brand in the factory settings - same way as I described above.

As for the sound issue, I would try to update the firmware, it wouldn't hurt, there is a separate topic for the FW for these units, you will find the links there, or here as well: https://autofather.com/s_sjjc

When doing the update, make sure you select the "erase all user settings" option, you will lose your stuff from the unit, but it's the best way to make sure it will work properly.

Hope this helps ;)

Our S.. board has space for Chip 360 soldered on two sides, and Chip Mekede is soldered on 3 sides and has a BT chip. Only TS-type units have connectors for Chip 360 on the tape.
[Android Head-Units] Micky001:
I see you have the LZ 20 pins canbus. The camera power supply wire, you have to connect on the wire from canbus pin 8 connector wire . The color wires may be different. I know that some people have recommended the "pink wire". In this case, there is not a rule, (talking about Chinese manufacturing) .See attached picture, I have a brown wire on pin 8 , and is work fine! :
[Android Head-Units] Mr.TT_NZ:
@Barykelo in post #5396 you mantioned about the DSP chip. Unless that's a misprint that is good.

You may be interested that I examined the S2 unit I have here and found it does not have a BD37534 chip, instead it has a BD37033 so I went on a hunt and downloaded datasheets for both. The BD37033 is completely compatible but has somewhat poorer specifications for noise and distortion so maybe in the factory the 37534's that don't quite pass final inspection are labelled and sold as 37033?

Anyway looking at the data sheets shows that those two chips are actually NOT DSP's, they are totally analogue. There is NO graphic equaliser function in them, only a bass, middle and treble adjustment that we don't seem to have access to in the software. This prompted me to look for the BU32107 datasheet which proved a little difficult to find but I got it in the end and that chip is a true DSP and has all the functionality that is claimed so that will be a big step forward for those who need those functions.

As an aside I still have not been able to find a full datasheet for the TDA7708 radio chip! There are many sites which have a shortform datasheet, essentially more of a sales brochure, but not the full thing. If anyone here ever comes across a full one please let me know the URL or download it and post it here. It will be a pdf with probably several hundred pages, that little brochure has only 9 pages. I do have the full data for the Si/TSC4745.
[Android Head-Units] Barykelo:
Yes you're right. I also have a BD37033 in S1 and it's not a DSP. Most of the sound settings are out of order.
[Android Head-Units] Tchutte:
thanks will try it somewhere this week.

I got a reply from the supplier asswell.

They sad connect the pink/beige wire from picture 1 (als picture 2). to the brown cable picture 4).

Picture 4 looks like the same cable you say.

Not sure of that is the powersuply of the camera, but will try that.

BTW picture 1 has the cables for the camera, where the pink/beige cable isn't connected currently to another cable in the connector.

Btw do you also have a Mazda?
[Android Head-Units] Dimitar Dimitrov 94:
@ScorpionSX thanks for the suggestions, but I already had tried to the one with setting the canbus.

The interesting fact is that there is no a section for my type of Mondeo. The lowest is with label "Mondeo 2010-2014 (Old)". I will picture it, but it doesn't help. I also tried to adjust it for FOCUS from my manifacturer year. Still the same.

According to the sound. I would try with update ( first I need to read how exactly should load the installation file and which file to download (from where, etc, but it is not clear for me how it worked at the beginning and then suddenly stopped. It bothers that could be possible some hardware part related to the sound burnt.
[Android Head-Units] Micky001:
No, I have an Opel Antara. But the LZ can bus is.. "universal", not specific to a specific car brand. Only the connections are identical on the can bus plug, regardless of the wires color , or the car brand where they are used. Connect it to the brown wire(pin 8), and it will work 100% . Just scrape the brown wire a bit somewhere, connect there your camera power supply wire , insulate it, and you will see that it will work.Just be sure that is the camera cable. The Can Bus will apply +12v to that brown wire, when you engage reverse.
[Android Head-Units] Tchutte:
Just to check do i keep the brown cable (pin 8) intact and merge the other cable on that cable?

Or do I cut the brown cable and connect to other cable to the brown cable?
[Android Head-Units] MauriBixio:
The Chinese are "smart". They often promise things that are not true... for this reason we recommend NOT purchasing the S1-S4, and investing a little more for the S8...
