@waybrief I have downgraded to version 1.73 UI 1.13 and it has the previous DSP Settings UI with no issue with too much low frequency sounds.
Thanks man, sorry to bother you any download link, can't find it in XyAuto website. This is the only file inside the directory.

Is it possible to only patch the DSP.APK from 1.72

Here is the DSP Setting app from version 1.73 UI 1.13. If it won't help, I can share with you the whole firmware file. Just send me your email address via a private conversation.

MOD Edit: Are there any requirements that the radio has to meet in order to install these 360 software? I have tried to install roundadas 360 also the 360view. And none of them open. I get an error message that it has stopped working. In my radio in factory settings, it has to activate the 360 switch but I don't have the app. I also can't get what I downloaded from here to work. Any solution?

Hay algun requisito tiene que cumplir la radio para poder instalar estos software de 360 ? He intentado instalar roundadas 360 también el 360view. Y ninguno se abre. Aparece un mensaje de error que ha dejado de funcionar. En mi radio en ajustes de fabrica, tiene para activar el interruptor de 360 pero no tengo la app. Tampoco consigo que funcione lo que he descargado de aqui. Alguna solucion?

El hardware debe ser compatible con la cámara 360.

Si la HU no viene con una aplicación, probablemente la cámara 360 no sea compatible.
MOD Edit: In the factory settings of the radio, I have the 360 cam switch and the specific connector for the 4 cameras. But the app is no longer there. Yes indeed. I have formatted the computer several times before knowing about these cameras.

En los ajustes de fabrica de la radio, tengo el interruptor de 360 cam y el conector especifico para las 4 camaras. Pero la aplicacion ya no esta. Eso sí. He formateado varias veces hace tiempo el equipo antes de saber de existencia estas camaras.

Updated to 1.73.3 released on 5/24. This update took longer than the past (rebooted a couple of times, seems one more than the past updates) and wiped out user data. So beware.

zlink activation code was wiped. But just like before when data got wiped, zlink eventually activates when network is enabled and app contacts the mothership (assuming your original purchase included zlink)

Do you mean that all the apps that you have installed yourself were removed as well as their configuration? And what about Android configuration. Was it lost too?

I use google maps and downloaded offline maps. Google map was still there but offline map and google login all disappeared. xyauto UI 17 patch I loaded got wiped but that could just be launcher name collision.

Since I don't really load any apps (not sure if google maps came with default, I recall not?) can't really say if the apps get wiped. But their data seems like it gets wiped. During the first reboot, I saw printout that said "erasing /data" and "dalvik" or something like that.

Android config got all reset too. Came with Chinese region time zone and 24hr format. I don't recall prior update did that.

I installed "Tesla" screen in my '14 Ford Fusion (Mondeo) that shows up as a YT5760B_00002_V001 "Android 11" with XY Audio 1.71 AC8259.

FWIW, I received a new version of ZLink from the seller yesterday and now Android Auto is in full screen, even in portrait mode!

v 3.9.40

I also noticed there's 4 icons in the bottom right now vs just 3.

Google Maps is included and I had lost offline maps too in some previous updates. But I hava never lost Google login. It may be not safe for me to update this time to not lose 360 app activation key - I have no idea how to backup it

I wonder if updates going forward will force a data wipe if starting with older than 1.73.3? I guess best if someone without worry of losing activation keys can try it first. I've had no issue with wiping zlink key as it just reactivates after establishing network (Original HU purchase came with zlink which means it is likely registered with zlink activation server) Have recovered it 2x now.

successfully updated to 1.73.3 :) I have a question: I have another head unit (in brazil we call it 'multimedia center' which has a crossover adjustment along with the equalizer, this is very useful to cut low frequencies in small speakers port, thus avoiding distortion, is this a hardware feature or just software? I haven't found any app with this function that works without root.

I loaded the chinese version of 7260L on my unit, and then got a voice assistant and other apps, lost my Google apps and store and Gmail, then loaded the latest 1.72 ROW and got everything back, but lost my IGO app and CarPlay / ZLink details, but not happy with the sound, it is echo at high volume and has no SUB control as supposed

    Good day my old friends, I used to be on here many years ago, with my HTC Desire HD, Galaxy S2, and came a long way with the community here, to a few years back. lost my username and started again new.

    Hopefully I can help again, I am just trying to understand this unit, and the codes, as I can work easier then.

    Please what is the Letter after the number, B, D, V, and L, such like 7260B and 7260L

    Side Note, the chinese version of software has extra features from what I have seen so far, to what came on the version I loaded after to fix the language and get Google apps back.

    I've been helping in this thread since the beginning of it, but so far, I have no clue what means the sequence of numbers and letters. Maybe it would be worth asking people having different units to report their AIDA64 details so that you can create a spreadsheet and try to find the differences.

    YT5760B AC8259, display 1024x600, 4GB RAM, 64GB storage, motherboard YT5760 ver. 1.1.1 2019-11-23, CPU 32-bit ARMv7, amplifier TDA7850 (ST7850), radio NXP6856, Bluetooth 5.0, Wi-Fi 5, SIM 4G (LTE), with 360 cameras, with CAN BUS decoder

    has anyone seen the original voice assistant as in the video

    How do we get this working, its in the Chinese file I downloaded and installed and then lost when going back to ROW

    I don't have this feature but read "HU's voice command" in this link

    YT5760B_AC8259 (google.com)

    I believe HU had to be ordered with this feature at time of purchase. Then license key is probably provided. But if user data got erased somehow, then probably erases the license key and require re-activation. If Toppal+ doesn't re-activate over network like zlink, then probably need to contact original seller if they can help at all.

    Thank you, I am not sure this is the same...

    The video shows, no voice first, "Hello Google" or say "Tappol" then ask question.

    The Chinese firmware ROM I installed had the Tappol, but was a button you press first to ask question, and didnt need activation to work, I didnt order my HU with this from them, it just worked, in Chinese of course.

    Please can we look into that seriously?


    Your first post #767 is YT3560 and post #777 is XY-3028V which looks like a dedicated voice camera control system.

    Neither of these are YT5760B discussed in this thread. As far as as I know, Toppal+ is the only solution provided on YT5760B. Maybe some chinese firmware version has Toppal+ activated by default (I don't know). For zlink this is not the case for foreign firmware (except xyauto made a mistake once previously in a foreign firmware and provided activated zlink)

    xyauto make many firmwares for different HU HW. They are not all the same. Google "YT3560" could not find much info but maybe xyauto integrate voice control by default for this model. Again, for YT5760B, this is not true.

    For google assistant (need to say "hey google") Post #50 says change horizontal resolution to be non tablet to make google assistant working. Users seems to have encountered various problems. Here is a link to search "google assistant" in this thread to see complete list.

    Anyway, I gave up controlling HU launching apps and adjust volume by voice control. Instead, most important for me was voice control to say "call personX" from my iPhone contact list. This was very easy as I described in HU's \voice command section ( link )

    I have recorder a video with the YT5760B system upgrade. It takes about 5 minutes to complete. In the attached ZIP file you can find the video.

    I have this hissing sound too, did you found what causes it?
    I didn't. I would like to install some low-pass filters on each wire to speaker, but I don't know what exact filter it should be.

    @videojo I believe that you did some amplifier upgrade. Did you have a similar audio issue?

    I have attached a recording of this strange sound - increase your volume level to 100% to hear it. At the end of the recording there is quite break when this sound disappears before next song starts.

    I have updated firmware to the latest version 1.71.
    • Setting up car's clock finally works with Mazda 6 GH
    • Annoying sound in the background did not disappear
    • DSP profiles work better since 1.70

    The above one with "ota" in the name of the file is the right one to copy onto a USB stick and to update the head unit. Usually, the second file is to update the firmware via PC

    Yes, I have installed 1.66. I do not have any issues with volume. RDS started to work from time to time. Wi-Fi hotspot with Headunit Reloaded app still crashes.
    I have taken the plunge to update to v1.66 without backing up the old ROM, big risk of turning the head unit into a brick but luckily everything turned out fine.

    My observations on the latest ROM:
    1. Android settings now report the OS as android 10.0 instead of 9.1, no idea if this is really true.
    2. New ROM did not erase the old settings and programs, but I could not login to my Google account. I had to restore to factory settings and setup everything from scratch.
    3. Split screen can be enabled in factory settings, same as my older ROM.
    4. Volume problem is still there, but seems not as bad as previous ROM. At least now I can set DSP to BBE mode and tune my Poweramp turning DVC off. Previously I had to use DVC so that I can tune to the EQ curve I want without encountering the volume problem, but with DVC I had to turn the master volume higher, which sounds ridiculously loud when I switch to Spotify or radio.
    5. Google Assistant asking to set as default still remains.

    Another tip for those who want to use Google Assistant to make a phone call, you need to go to developer options and find the minimum text width, which is set to 600 by default, and change it to something slightly smaller like 592. This will make the OS think it's a phone rather than tablet, otherwise Google Assistant will say "I don't know how to do that yet" when you ask to make a phone call.
