A bit overdue but I wanted to add some input here. Lately I've been looking at getting my unit up to date. I splurged and got the PX6 from Dasaita on amazon, expensive... I've been updating the firmware/MCU and currently I'm running the Hal9k Android 9, with the V3.71d MCU. I do have a similar "white noise" effect. I can almost hear it with the engine on and sound off, it's definitely noticeable with the engine and sound off. It does go away when music is playing from the radio, and it seemed like it went away when I got my phone linked up. I don't have subs, I just have the stock speakers. I am wondering if it's a WRX thing though, I have a 2018 base model WRX so maybe that's it?

Onto the task at hand, Zlink sucks butts and "Hot Audio" or whoever is developing the rom for these headunits could really do better. There is a lot of finnicky crap going on with these. I am running into the same issues using Carplay it seems. My phone(iPhone v14.4) will connect to the hotspot, and bluetooth quickly, then Zlink takes forever to do anything, then once it loads carplay up I can navigate the apps or listen to a podcast BUT of course my phone won't do anything internet related because it thinks it's connected to a regular wifi point. Eventually it does work itself out and it shuts off the wifi connection while still being linked to the head unit. I really wish this system worked a little smoother.

I'm going to give the update APK a shot, thanks OP for dumping the file, I have a file for Android 10 but of course I need Modinstaller pro to install it, or some rinkydink USB setup to basically sideload the rom. It couldn't be simple.

Hopefully Hal gets an android 10 version out, for now I guess I will suffer with 9.

Good morning all,

I currently have issues with running Apple Car play in my car( wired or wireless). For the wireless option I have connected to Bluetooth and Hot spot and it still does not work. For the wired I plug in my phone (IPhone 12 Pro Max firmware 14.4) and it charges but it does not connect to CarPlay nor do I get any prompts to run it on my car. I am currently running 3.74 ZLink on my Belsee 12.8 inch Touch Screen Android 9.0 Head Unit because it’s the only ZLink update I can get to install on my radio. The 4.06 and 4.08 zlink does not install on my radio ( I get an app not install error). I have been reading this form thoroughly and religiously and have been trying to get my apple play to work, if anyone can give me any kind of support I’d greatly appreciate it.
[MTCD Android Head Units General] talrhv:
is it a ticking sound? like tick tick tick tick...

if it is try to put some isolierband on all of your RCA cables the connected and the unconnected. wrap every piece of metal of those cables. it solved the ticking problem for me.

some of them probably touched the car's chassis and that made those noises for me.

Hi guys i have px5 android 10 head unit. Have wireless carplay and wired carplay. But there is no android auto. Can i add it ? It is software or hardware ? Thanks.
[MTCD Android Head Units General] talrhv:
Can someone upload the latest zlink version please?
[MTCD Android Head Units General] GruesomeJeans:
Nah not really a tick, more like a white noise hissing I guess. And it isn’t exactly constant, it changes, almost like a really bad radio station but it’s really only noticeable when the engine is totally off. I’m not exactly sure what it is, I assume some sort of interference.

TBH these head units have poor build quality, I also have an issue when it’s cold, for some reason if I start my car to warm it up, sometimes the sound gets screwed up and transfers to just the rear speakers It only plays on the rears and at full volume. Powering off and back on the unit fixes it but it’s very annoying.

I have no idea what the cause is but it’s really lame. It would also be nice if they just did OTA updates rather than these shenanigans.

Since the seller made me install an update, carplay no longer works (Zlink). I have bluetooth and android wifi connect without problem but do not link the radio. I do not know what to do .....

When carplay wireless with zlink wants to connect via the android hotspot the iphone asks me for a password ..... Anyone have an idea ??? I am blocked
[MTCD Android Head Units General] ruinertt:
The hotspot (on your head unit) acts like a WiFi access point. It has an SSID and password. You can look at (and change) the password by navigating to Network in setting and then finding the 'hotspot' menu item. Click on it and it should show you the hotspot configuration(s).

Moreover, it works wireless on my wife's Samsung Galaxy S9 Android 10.

In my case, I can reinstall the head unit Android upgrade that has included ZLink 3.8.8 with CarLife and no Android Auto, and without the activation code. I've asked several seller on AliExpress, but none of them sells activation codes.

I have top-spec head unit Dasaita MAX-10, Android 10, PX6, 4GB RAM, 64 GB of storage, IPS 1280x720 10.1".

ZLink app version 4.0.14 was preinstalled and activated on my PX6 head unit. I'm just sharing the app with others. I wish I knew how to activate the app, as then I would have installed it on my second car, but so far no luck.

[MTCD Android Head Units General] FMiguel91:
I’m having trouble with Zlink too

first i had issues installing. Would say”app not installed”

but with APK editor managed to solve that changing the installation path to internal.

Now, if I use any of the version you guys posted here always have this error :

But I’ve installed the apk the guy who sold me the android head unit (Belsee) with version 3.6.0 and went through with no issues but is asking me to activate it

I don’t have WeChat so can’t do much at this point and the guy who sold me doesn’t help.

Is there any chance to change the apk channel from “hengchangtong” to “sinuowei”?

Hi, I managed to solve the problem, this was not easy. The problem is that the audio signal goes from the (pre)amplifier in Head Unit (HA) to the Bose system, which has it's own amplifier, and the rustle appear. It's needed to connect the audio linear output from HA to Bose. For that needed to cut 8 lines from main socket (pins 7-10,17-20) and solder 4 male RCA connectors to lines, which go to white socket connected to the car. These 4 RCA connectors should be connected to the connector A (FR, FL, RL, RR), which provide liner audio output.

Can you please share the proper way to update ZLink? I have a HA2135-MAX10-CP and want to make sure I install it correctly. Do you install with Titanium or some other third party app?

Also curious if anyone has pinpointed the correct way to setup the Dasaita MAX10 CP with wireless Android Auto. I have gotten mine to work here and there by connecting to hotspot but it seems inconsistent. I read many pages of the thread but doesn't seem like any of us have nailed down the proper procedure. I've reached out to Dasaita support as well so if they do come back with instructions I will follow up and post here.

Best is to install the complete march update of android 10 for the Max10, which works very stable for me.

I cant make zlink work on v4 and above.

I install just by replacing the apk file on the oem/..... folder and by giving the correct permissions . For versions 3.x.x. I can get it work as android auto on my s10+ but never worked wired or wirelessly from version 4 0 and above.

Is there anything wrong what I am doing?

[MTCD Android Head Units General] marchnz:
So not an MTCD/E Device.
[MTCD Android Head Units General] jlbooth:
And I washed the windows, wiped the dash, and shined the tires.....(to add to the list that included installing TWRP)

The thing with this ZLink app is that one of the first prerequisites seems to be that the factory ROM for the head unit has to come with a version of ZLink pre-installed in the version numbering that you're trying to get to work. If it doesn't have ZLink pre-installed, then it is highly unlikely you will ever get it to work.

If it has 4.x then you should be able to get another 4.x version to work. Just because an app will install on a head unit or if you copy the .APK somewhere does not guarantee that it will ever really work. That whole "Inactivated" (good Engrish) business is for the ZLink app to examine the hardware and see if it's "supported" and give you a cryptic error message if the hardware is not supported.. It is not really "activating" it is trying to figure out if there's an agreement between the Chinese outfit that made ZLink and the maker of the head unit.

***end rant
[MTCD Android Head Units General] iagobkstar:
Could anyone tell me how can I update the app to 4.0.23? From what I've read in other threads, it's a killer upgrade, but the update button does not do anything in my unit! Do I have to do anything in order to make it update itself? I'm in 4.0.17, tried 4.0.21 but AA wireless does seem to break in that version...

There are a couple issues in 4.0.17 that make me want to desperately update. First of all, the wireless connection is finicky, it'll work 9/10 times without issue, but that 1/10th time drives me nuts. I have to take my phone off my pocket and plug it in, many times forcing me to stop the car. Secondly, when listening to Spotify and changing songs with "Ok Google" commands, the volume is super low and it doesn't return to normal until there's a GPS indication (this is 100% repeatable). I know the first issue is resolved in 4.0.23, but do you know if the second is also solved?

Cheers

Hi there ikerg can you please give more detail on how you installed this version on hal9k.

just copied over the zlink apk and installed with a file manager? but how did you update the libraries like you say? Thank you
[MTCD Android Head Units General] iagobkstar:
If your radio came without a working Zlink app, the chances are you are missing the hardware to run in, and you must buy a dongle. However, if your radio had a previous version of Zlink, in my case it worked by directly installing the .apk as any other .apk. Try first, there's nothing to lose. Make a backup of your preinstalled version of Zlink just in case, but if it's installed as a system app, if you uninstall the version you have installed on top, it should revert back to the factory version.
[MTCD Android Head Units General] khaosengine:
Nice one! Yes my px6 has zlink installed, stock android 10 4.014 version. I’m playing with the idea of installing hal9k and installing this zlink update .23. My stock rom is not rooted tho
[MTCD Android Head Units General] iagobkstar:
It will work then, just make sure you install the correct version for your device of hal9k. That's actually what I did, I backed up my Zlink 4.0.8 apk, installed Malaysk ROM (which in turn installed Zlink 3.X.X) and then installed Zlink 4.0.17 as a normal apk. It just worked without workarounds. If you decide you want to rollback to the old version, just download the latest firmware from your manufacturer and install it; it'll reinstall the Zlink app.

PS: if you're able to find Zlink 4.0.23 apk, please share! I'm interested in updating...
[MTCD Android Head Units General] khaosengine:
Thank you, sorry I meant 4.0.21 which I found a link for on this thread. Are u running malaysk android 10, or 9? My stock rom came with .14 android 10…
[MTCD Android Head Units General] iagobkstar:
I'm running Malaysk PX6 Android 10. Hal9k is not yet available for PX6 with Android 10. I believe we were in the same situation to start with. Also, I would recommend sticking to 4.0.17 if you want to use Android Auto Wireless, it does not work in 4.0.21.

[MTCD Android Head Units General] Apollon2:
You should mention which exact model you have. If it doesn‘t have built in carplay there are usb dongles for that. But I‘m not familiar with these.

And if it‘s new you might want to consider returning it and buying one with integrated carplay..

[MTCD Android Head Units General] Takeshikovacs99:
I didn’t get you ?

which head unit does my device come in

I don’t know the model or brand name
[MTCD Android Head Units General] jlbooth:
You have a generic unbranded 8227L with a YT9216BJ processor. If your unit was MTCD/E then you would see MTCD or MTCE on the about page that you posted. Posts for non MTCD/E/x go in the Android Head units forum.

To answer your original question, you will need an external dongle to be able use Apple CarPlay with this unit. Be advised that many of the dongle devices on the market often stop working when Apple provides updates to your phone as the dongles are not Apple certified.
[MTCD Android Head Units General] Takeshikovacs99:
Is there any way by root i can install and run zlink on it?
[MTCD Android Head Units General] iagobkstar:
If Zlink didn't come preinstalled with your radio, then there's absolutely no way you'll get it to work by just installing the apk. Zlink requires hardware, it's not just an app. However, as it was said in this thread, there are USB dongles that can provide wired Android Auto/Carplay capabilities. Search for those on AliExpress.
[MTCD Android Head Units General] Takeshikovacs99:
They’re reliable ?
[MTCD Android Head Units General] iagobkstar:
I have no idea, as I've never used one. They're rather cheap, about $25:

https://www.aliexpress.com/item/1005001616316987.html?spm=a2g0o.productlist.0.0.3de449d3uvJgXU&algo_pvid=ed56b039-b8e1-4fdc-afe7-1ae11e0fc4f4&algo_exp_id=ed56b039-b8e1-4fdc-afe7-1ae11e0fc4f4-0

These dongles don't use the Zlink app. Instead, they use their own app (called AutoKit), so I cannot speak about the performance and features that such app will provide for both Carplay and Android Auto.
[MTCD Android Head Units General] abnormalreply:
Is there any way to get wireless android auto on a unit that already supports wired? Wired is supported via the CarLink app.
[MTCD Android Head Units General] iagobkstar:
I don't think so, unless the manufacturer/CarLink developer eventually decides to include that feature (I don't even know if it's physically possible with the antennas your radio has). Zlink is similar to CarLink, but requires specific hardware in your headunit, so installing it in a headunit where Zlink didn't come preinstalled just won't work.
