Hey guyes, I still have this issue with no sound on anyone of the possible options:

Radio

Youtube

Embedded songs

Bluetotth

Here is retrospective of my story:

Bought media from Hizpo Store in Aliexpress couple of months ago

After mounting it I noticed the media starts when I plug in the power cord - without the car to be ignition on

I asked the seller and he sent me this image in order to connect my media the sam way

When i connect it this way there was sound on the Radio, on the Youtube, on the Spotify, pretty much from everywhere

I started serching for a way to make the media turn off when ignition off the car

I reeset the factory settings. I'm not sure this was the reason - but after did it - the physical buttons on the media stopped working, also the souind missed

I found out that I have to "learn" the buttons. I did it and I had them back working as intended, but the sound still missed

I've updated firmware of the media - the update was successful but the sound is still missing.

I want to ask:

1. Has the media sound card or some sound chip that is possible to burn ? Is it possible this happened at some point?

2. Is there a way using some application to test if the sound from media is working fine?

3. What does "buzzer" stand for visible in one of the images? It doesn't matter if is switched on or off. Both cases there is no sound.

4. How to understand if the car has embedded amplifer? Can I check this somehow?

5. There is an option in the factory menu where I enter with password 8888. The option is named "Power amplifier" or something similar. What should be the defualt value there? Also - it doesn't work swtich on or off

6. I tested something else - I connected the external microphone to the media, then I connected my phone via Bluetooth to the media and make a call. The person on the other side was able to hear me, but I didn't hear anything. No sound at all. Which if I understand correctly means - the sound from micrpophone that is connected to the media has been successfull transformed thorugh the car. What should this mean

7. Also, If I change the option for "Button click" to be sound - still not able to to hear any sound when click some stuff on the media

8. Based on the sound settings visible on one of the images - the sound is not muted and it is expected to have it.

I'm really desperate already.

I tested all possible scenarons - with connected AUX IN R / AUX IN L , AUX OUT R, AUX OUR L

I tested without any additional cables connect just the main connector - there is no sound.

I just expected that will plug and play the media and everything will be fine, but not ....

I'm open for everything.

If anoyna has some other suggestions I will rest them.

The car is Ford Mondeo MK4 2007, the canbus is "Hiworld"

I forgot to mentined that if I return the original Sony unit - there is sound.

If connect my phone through AUX cable using the default aux and origina Sony unit I'm also able to have sound.

Thanks in advance!

i have other radio JUNSUN 9 inch, i think is better.. no probem
[Android Head-Units] Barykelo:
Unfortunately, you cannot use 5GHz, the car radio does not see 5GHz wifi on high channels (mobile broadcasts on channel 149).
[Android Head-Units] PrinceLc:
Also my S8 have no problems with WiFi 5Ghz and 2.4Ghz so I don't know
[Android Head-Units] PrinceLc:
The firmware don't have notification you need to install third party apps like one shade. The firmware don't have documentsui it's missing
[Android Head-Units] PrinceLc:
Very strange I have sound nothing connected to the RCA cable for sound only the quadlock and Canbus do the job Passat B7 from 2014
[Android Head-Units] Barykelo:
Interesting, I also have an S8,S6,S1 and a Samsung (M52 5G) and the HU doesn't see the 5GHz hotspot. You probably have a different wifi chip.
[Android Head-Units] kwiedo72:
I had the exact same problem with my 2012 ford f150 due to the OEM SONY SOUNDSYSTEM.

You can connect an external speaker directly to the car radio, if you do have sound you know that the problem is probably caused by an amplifier in your car or the wiring
[Android Head-Units] PrinceLc:
I don't know but WiFi works well
[Android Head-Units] Sterg1967:
Thank you my friend for answering,something like that I understood,it's ok 2,4G wifi but more faster 5G,thank you.
[Android Head-Units] roninet70:
ok thanks for the help. Could you show me a simple slide that could be valid?

i see https://play.google.com/store/apps/details?id=com.treydev.pns

but now I haven't had time to try. It could go well ?
[Android Head-Units] PrinceLc:
One Shade is better power shade was not so good but yes this are the apps to bring back notifications. Give the apps permissions and put in Whitelist so the system don't disable them
[Android Head-Units] MauriBixio:
What kind of notifications are shown with the One Shade app?
[Android Head-Units] itiswitis:
If you start zlink for Android Auto, it'll consume the 5ghz band for it's "hotspot" (it defaults to 5ghz). So you can't dual run zlink and try to connect to another hotspot on 5ghz.

I have older S6 unit still running QF01 MCU. It connects to the 5ghz hotspot on Galaxy S23, but 2.4ghz is fast enough for youtube/spotify/etc.
[Android Head-Units] PrinceLc:
Example how
[Android Head-Units] PrinceLc:
Also all notifications you set up telegram WhatsApp YouTube like on smartphone
[Android Head-Units] sterg67:
Hi my friend,you are right about zlink if I start it but I do not start it,anyway 2,4g as you say it's enough for many apps.
[Android Head-Units] Barykelo:
So I have no idea what happened but all my units can now see the 5GHz hotspot from my Samsung mobile.
[Android Head-Units] PrinceLc:
That's good 👍
[Android Head-Units] Barykelo:
It's broken again! I do not get it!
[Android Head-Units] PrinceLc:
Oh ****ty

I 've purchased a Hizpo S5 a couple of weeks back...

It's not the most user friendly system I've had in my life but given its price and the fact that it's Chinese I do get by.

Yesterday while I was meddling with it I managed to make my HU keys stop responding (the ones surrounding the screen). I made a factory reset but no joy.

I'd be much grateful for any insight gents....
[Android Head-Units] Dimitar Dimitrov 94:
I have three new questions:

1. Based on the comment in the first page of the topic:

I got an extra code meanwhile 15935700 turns of sleep mode when leaving the car so when taking off the car key the units shuts down after 3 min delay in stead off going into sleep mode and possibly draining the car battery.

How/where this code should be executed.

2. Is there specific Setting for adjust the sound gloablly?<

3. Is it a problem that the Firmware is a different than MCU? And what is MCU actually?
[Android Head-Units] PrinceLc:
In factory settings there you enter the code.
[Android Head-Units] Dimitar Dimitrov 94:
I've just updated my post.
[Android Head-Units] niklos44:
Thanks a million Barykelo. I have a different layout, but it worked anyway.
[Android Head-Units] akos_202:
I’ve found a solution to my rear volume problem in my 2007 Audi A4. So if anybody has a problem with sound on cars that have factory amp, you have to install a high-low line converter in order to give optimal signals to the amplifier. Now it sounds like a dream!
[Android Head-Units] amedello:
I have a HIZPO S8 car radio with 4g. I would like to use it in standalone mode. I installed the phone application from the play store. However, I am experiencing some problems.

The overlay to answer calls is not displayed, even though I can hear the call sound in the speakers.

If I make a call, it is muted in both directions.

Any solution?
[Android Head-Units] MauriBixio:
As we have already written, these units cannot be a true stand-alone phone, but only work via BT, paired with YOU phone.
[Android Head-Units] PrinceLc:
It's because the unit is based on a tablet some units are based on smartphones so then you can install Google phone and call with it like some Junsun device
[Android Head-Units] tokori:
what happened after you selected those buttons? I had did that but experienced nothing
[Android Head-Units] tokori:
I reinstalled my HU this week, and then the HU display showed noisy output. I bought it from Ossuret in Nov 2023. I reported it to the seller but any advice from you guys are highly appreciated :)
[Android Head-Units] PrinceLc:
Check inside display cable connection
[Android Head-Units] tokori:
do you mean the cable connection between the board and the display

Or cable between the unit and output cable?
[Android Head-Units] fitti2:
Hey guys!

Do you know of a truly anti-reflective film for S8?If so ,where cam I get it?Thanks!
[Android Head-Units] Barykelo:

[Android Head-Units] Mohamdps:
Hello man, I bought an S7 from Hizpo and a bootloop happened to me. I spoke to a seller and he sent me an auto update and it did not work. There is a solution. Thank you.
[Android Head-Units] Atrumitos:
Hi all. I also have an S8 from Hizpo.

For some reason I cannot get bluetooth tethering to work. Anyone got suggestions? It's set to "open" in the bluetooth pairing settings, I have reset the bluetooth multiple times and I have also enabled the bluetooth options under "factory settings".

Phone is a Galaxy A54. I have enabled bluetooth tethering in its settings.

I connected the sound blasterx G6 USB sound card.

The sound is great, but the microphone in calls via BT - it is difficult to understand what I am saying.

Recording Sound from the microphone, Google Assistant works OK

The microphone testing application also records sound well.

Why doesn't BT calling work well?

On an Android phone, the DAC works fine

Hello everyone!

i have Hizpo S8 8Core 8G 128G and am trying to upgrade/update it. i have downloaded the files from here: https://autofather.com/s_sjjc

and when am trying to update system appears this massage. i have enabled the check for corruption..or should i not? what the message means? do i have the latest update already?

thank you in advance!
[Android Head-Units] roninet70:
Good morning

I have an S8, the seller told me this update is available.

these are the links I received

The system firmware link：

https://jitu2firmware20240111.oss-eu-central-1.aliyuncs.com/update.zip

The MCU document link:

https://mcu32107770820240106.oss-eu-central-1.aliyuncs.com/mcu.bin

Can I ask if you already know?

do you know what is better (or worse)?

Do you recommend doing it?

I have never updated this unit, I previously had the JUNSUN model, I wonder later if after the update, the unit will be completely reset?

Do I lose all the settings and downloaded apps?

Bye
[Android Head-Units] Aaantonn:
If the latest update is 2024, then yes, you will have to erase all data. If the update is before 24, then when updating you need to uncheck the box - erase all data, then everything will remain. It is impossible to say what will change for you without knowing your firmware version.
[Android Head-Units] Ziutx:
Had anyone else have wifi suddenly fail in their device? My device is an S8 8/128 DSP BU32107 Radio TDA7708

I've been using this radio with a wifi router for over half a year without issue and now it either doesn't connect to wifi at all showing "failed to connect to network" error, or it will connect, work for few minutes at most and then lose connection. What's weird is that even tethering through USB doesn't work properly, it keeps disconnecting every few moments, so at this time my device is left without any internet access.

I tried using different routers and differen phone hotspots, the results are the same with all of them.

GPS also has a hard time getting a fix and loses signal where there were no problems before, though I'm not sure if it's related to wifi issue (I have the gps fix from this thread applied).

So far I have tried most common troubleshooting steps including resetting network settings in android, full reset of the device with 22558800 code and making a clean upgrade to newest firmware and mcu.

The seller is not very helpful, so far they told me to do a factory reset and record logs and after I've done that they've been ignoring my messages for 2 weeks now.

I think it might be a hardware issue, but maybe someone here can help me with some advice, thanks in advance.

Hi! I have written in Recovery topic but I see that this topic is more "alive" so would ask here also. After by mistake flashing qfdata from some other post (wanted to auto flash whole update, not display parameters) I had a lot of flashing white dots on the screen. How can that be fixed? Thanks!
[Android Head-Units] PrinceLc:
Ah you flashed already qfdata ok hm you can be lucky that you have a working screen and not a black screen after flash the complete firmware by flashtool. Sone have a black screen after.
[Android Head-Units] zokipirlo:
Yeah, it was also black for me too, when I reinsert connector. Need to disconnect and reconnect to battery to got it working again.
[Android Head-Units] alexopoulos.thomas:
HI guys! I have read a lot of posts recently. i didn't find any to match my problem. I have an S4 model and MCU details are in the pic below. I never managed to store any of my memory presets in my radio. Every time I turned on the car, my HU started from cold...just yesterday, I updated my system and managed to have options like sleep time. I chose to let it sleep for 3 days, so I don't have to scan all my favorite stations again and again..but even with it selected, my HU made a cold start eventually despite some successful hot starts from sleep mode.

I do not know where the problem lies. SO i read numerous post about QF01 and QF03. The thing is that I couldn't locate a link somewhere to download the latest update for my MCU QF1. I went to authorfather selected for DSP BD37354 and for radio TSC4745, but strangely the bin file that I was given seems to be a QF05 version as in the second pic, which results in noncompatibility. Of course, I don't want to force the upgrade. Has anyone a link available for a bin file that matches my details? I would be grateful.

Also, regarding the radio stations, I have already triple-checked my wiring, and it is correct.

Thank you in advance

You can also try to make a small fix - try to make a call via bluetooth and then the sound volume for music should be hearable :)

How did you connect that card? Have you used optical in? Do you have sound in every app and can control the volume?

Hi:

I got a S5 from Hizpo 6gb/64gb and I have a problem with the external USB, the first time I install the app of tidal i can save the music in the USB but I uninstall and when reinstall I can´t see the external USB in Tidal, the radio unit recognize the external USB but dosn´t appear in Tidal or Spotify. I change the firmware and MCU 2 times but stay the same. Music can read external USB without problems. What can I do?

Tried fcc launcher ,but didn't support tomtom on the home screen.

I thought i had it fixed with Tasker, everything works when i reboot, but when i turn of the car for a minute and the start the car (without sleep) the HU reboots and tasker doesn't work because accessibility is disabled. Does anyone know how to keep accessibility for tasker enabled?

Tried the line in adb but didn't work.

[Android Head-Units] afigienas:
i think device already have builtin startup manager it's called whitelist...[somewhere in settings] when you put app in whitelist of sleep..forgot how chinese translated this nonsense, application that is selected and if was launched before device shut down -it will launch it on startup.
[Android Head-Units] afigienas:
Forget it. Also device is ALREADY rooted, ADB have root rights. So you can do almost what ever you want with the system. If wanna be safe-do this way, others is risky, nobody is really tried it and when you screwup-there wont be any help. All needed info already in forum.

Its outdoor temp on the car

At least on my unit
[Android Head-Units] lala1:
Thanks ,but don't need magisk. Got Tasker to keep running.

This is how i did it:

-ADB connect to the device

-Then put in this line in

adb shell pm grant net.dinglisch.android.taskerm android.permission.WRITE_SECURE_SETTINGS

-Reboot device

-Go in to tasker

-Hit the hamburger menu, right upper corner

-More/Android Settings/Accessibility Settings

-Enable Tasker

-Go back

-Hit the hamburger menu again

-Preferences/Monitor/KEEP ACCESSIBILITY RUNNING

-Check Tasker

-Reboot

Now Accessibility for Tasker will keep being enabled when you turn of the car (without sleep), and restart.

I installed magisk and now tasker has superuser access, so everything works now.

well in my case it's not outdoor temp i do not live in hell :D also car shows 8c and head unit 56c :) It's logical to asume it's device's cpu temp but when i go into FAN it shows like 42c and not 56c. Seen every numbers i could and none matches what's showin' in top left corner :) Also this numbe ronly apears at some point, usually it's not shown..i guess after some treshhold numbervit starts to show as a warning i guess.

I hope you have a multimeter because this is going to be fun!

You need to check if the pins in the harness are connected correctly, 12v+ must go to pin G2, and pin G8 is whats supposed to get +12v from when you turn on the ignition.

Hi, guys!

I didn't find information, so I'm writing this.

I have S8 unit, my car has factory amplifier. Everything works fine, but in CarAPP I need to raise the VOL slider, because it doesn't save it. When I restart the media, the slider is at the same position, but it needs to be touched in order to start functioning. The sound is a little bit weak, so I'm tuning it using VOL slider in CarAPP, but how can i make it apply the changes on each restart?
