Chinese Head Unit - How Frustrating Can It Be

Hello All,
There is much information on this forum which has helped me so far on this android head unit journey but I am almost at the position where I might throw the damn thing out of the window and reinstall the basic manufactures head unit.
I bought the head unit from a dealer who is no longer in business and cannot contact them which closes off the normal route for enquiry.
The headhunt appears to be a generic Chinese manufacturer. The config shows as:
MCU Ver: DH200729T512188X611200805
FrameWork: 9 PQ2A.190305.002 eng.work2.20201208.100955
Android Ver: 9
App Ver: 2020120801T_1280x480_970
Tablet: rkpx6
The bluetooth function has been disabled which was originally a problem when using an iPhone as you have to hotspot every time. I overcame this with a wifi dongle and 4G card.
The GPS is terrible as well (part of the problem is the number of high rises that shadow the road). One of the main reasons for upgrading was the navigation which I generally cannot use.
So I thought a CarLinkit adapter would solve all of my problems which it did - although I get horrible screen interference that makes the unit completely unusable. The interference is completely random and CarLinkit have said that the problem is the head unit and not the adapter.
I've removed the adapter now and have to use my phone for navigation which works but doesn't solve the problem I originally tried to solve.
I seem to remember that the android version was originally ver 8 and it appears to have upgraded itself to version 9. When I play music know it takes about 2 minutes for the sound to come out of the speakers (even though the music appears to be playing). It only happens on the first boot of the head unit.
I'm currently banging my head against a wall with this technology and it appears that updating and not knowing exactly what you are doing could brick the system.
So my questions boil down to:
a) are my carlinkit issues really related to the head unit?
b) why would sound be delayed by 2 minutes after the unit has started?
c) what is the latest software I can apply to this head unit?
d) is there a better unit that I can install that will be much more reliable out of the box? there appears to be other head units available although I need a RHD option which many of the sellers on AliExpress saying isn't available.
Hopefully, I can gain some experience from others on this forum.
Thanks in advance,
DC

Any android head unit with less than 2GB RAM will be a dead zone to run apps or the OS. Apps crash a lot and OS doesn't perform well. I am not sure about your head unit's RAM capacity.
Alternatively, I would suggest uninstalling/disabling the apps that you don't really require through system settings >> apps

No sound after HU wakes from sleep

I'm a newbie to this site so apols if I have contravened any site rules!
Hoping someone might be able to help. I bought a 12.3inch HU on AliExpress. Its model number is uis8581a2h10_Automotive, which I think is a FYT HU. It's coded specifically for BMW.
After a full boot everything on the HU works fine. But then if I stop the car, for example to grab something from a shop, when I start the car again the head unit starts up instantly but there's no sound despite Zlink5/Spotify appearing to run properly on the screen. The only option to get sound back is to reboot the head unit and wait for Zlink5 to reestablish a connection with my phone (a Galaxy S10). Interestingly though, even when the music fails to play through the speakers, if I press the microphone button, Google Assistant plays sound and can properly make a phone call played through the car's front left speaker.
Also, when I'm getting no sound after the HU wakes, if I switch to the DAB app, I can hear a millisecond of Spotify music before it cuts off, and then the DAB app also fails to play sound - although it too, like Zlink5/Sportify, responds properly onscreen. So the HU seem to be playing music after waking from sleep, but just not routing it to the amp.
Apparently this unit is supposed to output sound via an aux cable which plugs into the BMW stereo's aux port. However, my unit plays music through the speakers on the aux setting whether or not the aux cable is plugged in. Not sure if that's affecting things?
The final issue is that Zlink5 won't work with bluetooth and WLAN/hotspot at the same time. It switches off WLAN while connecting to my phone via Bluetooth. If I then enable WLAN and set up a hot spot, Zlink5 either switches WLAN off and reconnects via Bluetooth, or else it will connect to WLAN, after which music pauses every second or so.
The sellers have sent me an MCU update file, which I have applied, and I have also tried every option in the HU settings for Car Aux Switch Mode. I can't think of anything else to try.
Can anyone advise whether these problems are likely to be software or hardware related? And has anyone any ideas how they might be resolved?
Many thanks!
In regards to not being able to use Wi-Fi and Bluetooth together when you use zlink it uses the wifi to connect to you phone in the background. If you manually turn it back on it will disconnect from your phone. My advice would be to put a SIM card in your unit.

Many thanks for getting in touch Marchnz. The MCU is ZLH_BMH220425A_8581. The original version was ZLH_BM_OS_1.37, but the seller has since provided an update to ZLH_BM_OS_1.53 which has fixed the problem.

HI there, I've found the update but it's 1.4Gb or so. Can you send me a DM with your email and I'll send it to you via Wetransfer? Obviously its use would be at your own risk, as I'm not sure whether it will work across different manufacturers/companies.

Junsun V1 pro 8/128 - no app sound

Hello everyone,
recently i installed a Junsun Head Unit in my Audi TT MK2 (2012) with the bose system.
I had a xtrons PX5 before that worked like a dream until the touchscreen died.
The JunsunHead Unit works fine, but there is a strange behaviour i can't figure out.
Everything is connected through the quadlock and a canbus adapter from the seller, also there is a aux harness connected. pretty much standard stuff.
My problem:
The integrated radio app has sound. Music via Bluetooth works also just fine.
Every third party app like youtube, spotify, waze, maps, ... has absolutely no sound. nothing.
Googling my problem wasn't really helpful. Connecting the AMP CTRL Wire to ACC oder every other 12V wire to activate the bose amp in the trunk doesn't do anything, still no sound. And yes, the amp is working just fine, when i connect the amp ctrl wire to the powered antenna while using the radio app you can hear the difference in the sound qualitiy because of the amp working, but like i said you also have sound without the connected amp so there should be sound in any other app also, right? I don't want to listen to radio stations all day - i want spotify
In the hidden menues every setting looks just fine, everything works except the sound in app.
So my guess is the firmware, i already contacted the seller but he didn't responded yet.
Is there a newer firmware available? Or do any of you guys have any idea how to fix my problem?
One more thing: how to do a factory reset on this unit? Is there a code or a special way to press the touchbuttons...? Is it the "erase all content" in the factory settings?
Thank you so much in advance!
no idea?
How is audio output connected to your car/amp? SPDIF coaxial?
Android head unit. Some apps no sound. Radio app has sound.
Hi all. I stumbled upon these forum by googling my issue. So far I haven't found any answers to my problems, so hoping for some help from the great people on here. I have recently installed a seicane 10.1 android head unit into my jeep wrangler...

I've seen this thread. Didn't really help.
Everything is connected through the OEM quadlock (with bose) + the canbus encoder and AUX left/right in the wiring harness.
Spoke to the seller several times now and he has no idea either. He's sending me a new firmware the next few days to test... otherwise i'll send the head unit back. Must be some software issues cause some apps have sound, others don't... doesn't make any sense to me

The radio app is only an interface to control the radio hardware. Bluetooth may be the same. So it makes sense.
Hey everyone,

ZLINK on Idoing px6 MTCH

Hi there,
I am new to this forum and have recently installed an idoing version mtch px6 with ZLINK for andoid auto.
First question. My ZLINK version is 4.0.41.4. How do I know if this is the latest version? The resolution on ZLINK looks very enlarged and not very elegant. I was hoping it could be updated to improve the resolution.
2nd question - Whenever I make a phone call, my audio stops working. The person I call can hear me, but as soon as I press the call button, the audio cuts off (there is no typical ringing sound and I cant hear any voice). Obviously the mic is working fine as the other person can hear me well.
3rd question - Randomly my right speakers will stop working. It isnt a speaker issue as they were fine before the idoing installation. Maybe its a connection issue in the back of the headunit OR there is a issue with software.
Any help would be really appreciated!!
Cheers,
Julian

Op, also no one will know what your unit is without posting details including screenshots from Android system information. The first point of contact being the reseller of device, what do they suggest?
