Has anyone forced the zlink application to use the split screen/widescreen version of Android Auto? I'm running a 9" Eonon Stereo on a BMW E46 and feel it's a waste of screen realestate. The device previously worked with HUR on Split Screen up until HUR stopped supporting Android 12.

z link new version 4.0.37
[MTCD Android Head Units General] iagobkstar:
Thanks! Where did you get it from? Is there a new ROM that ships with it?

Who can help me on zlink app? I have unit zq8003, seems like zlink app from this thread links is not working
[MTCD Android Head Units General] Jesshobson92:
Hi i have rage deleted my Zlink because it wasn’t working properly thinking I can easily download again and nothing is working.. any help on redownloading
[MTCD Android Head Units General] jlbooth:
I just don't get why people delete Zlink from their head units and then wonder why they can't reinstall it.

ZLink is provided with the manufacturer firmware updates. To restore ZLink to your unit, you will need to obtain a proper Android firmware update for your unit from either the manufacturer or the reseller.

Then there's the other crowd whose head units did not come from the factory with ZLink pre-installed.

It is not a simple matter of downloading the ZLink app and reinstalling.
[MTCD Android Head Units General] Jesshobson92:
Believe me I really regret it now, it happened after my phone auto updated.. what do I do about obtaining a proper Android firmware ? Where do I go or what do I do about it ?
[MTCD Android Head Units General] jlbooth:
At least you're not in the second crowd whose unit never had ZLink to start with.

First, we need to determine if your unit is MTCD/E by looking at the About System page. Please post a photo of the About System page or copy the information from that screen so we can figure out the manufacturer of your unit and Android version information.

Then maybe the community here can help you find an appropriate firmware specific for your head unit. Links to download firmware updates for most manufacturers can be found right here on XDA, but it has to be for your specific make and model unit and same Android version, etc.
[MTCD Android Head Units General] Jesshobson92:
Does that answer anything, honestly I am so bad with technology 😩
[MTCD Android Head Units General] jlbooth:
You may need to scroll up on the about page. We're looking for a string starting with MTCD or MTCE. Your screenshot doesn't provide anything about the manufacturer of the unit. That detail could be determined from that MTCD/E string.
[MTCD Android Head Units General] Jesshobson92:
Is that what we need ? I literally thought I could go into App Store and Download it again 😂
[MTCD Android Head Units General] Taha429:
I have the same Zlink version as you and literally the same problem as you. Have you found a solution? And I was wondering if your head unit supports 5.0 GHZ hotspot?
[MTCD Android Head Units General] marchnz:
Not an MTCD unit, wrong forum.
[MTCD Android Head Units General] marchnz:
Is it MTCD, are you posting in right forum
[MTCD Android Head Units General] Taha429:
Is it ? If not can you tell where to go ?
[MTCD Android Head Units General] Hennawy:
unfortunately i didn't found a solution, i don't know if it support 5.0 GHZ hotspot.
[MTCD Android Head Units General] yildizomer89:
I wonder which mtcd/mtce? Can you help me?
[MTCD Android Head Units General] aurisb:
Who can tell.me what kind of device is this?Is

Try updating your firmware it will update zlink and wireless aa will work I just updated my firmware using dasaita public firmware and it had zlink 4.0.32 and wireless aa is now working for me
[MTCD Android Head Units General] milad5124:
Hi.

i have PX30 android headunit (android 10)

but my Zlink ( Ver 4.0.17) app is inactive

i need authorize code for active it

can You help me to activate it?

thanks
[MTCD Android Head Units General] iagobkstar:
Did zlink come preinstalled with your radio? In case it didn't you're out of luck: you can't just "enable" zlink, it needs some sort of licence that you can't purchase, only the radio manufacturer, and perhaps some dedicated hardware (I'm unsure of this last thing).

In case your radio did ship with zlink: Have you tried connecting the radio to the internet? I believe something like that has happened to me once after an update, but it went away as soon as the radio got connected to the internet an I opened the app (no extra steps).
[MTCD Android Head Units General] alchemist76:
Hi to all I'm a newbie please someone can help me to update z link app on my device? Now I have 3 firmware and I see that the latest is 4.0. 32.when I try to update through the update botton the system show a message that the app it's update. Thanks in advance for your help
[MTCD Android Head Units General] iagobkstar:
It has been explained earlier on this thread. Basically, you have to uninstall the old zlink apk and reinstall the new one, for which you need superuser rights (i.e., a "rooted" device). To root your device, you need to follow a guide for your own device, which is not an MTCD or MTCE device (I can't help you, I've no clue on how to do it on that radio you own).

Also, the Zlink apk you will find in this thread *won't work on your device* and you will *lose all zlink functionality if you try to install it*. You've been warned! You will need a specific version for your radio manufacturer. The easiest way to get upgrades is asking your vendor for an updated version.
[MTCD Android Head Units General] ikerg:
Is there anything that does not work? Why do you want to upgrade?

Note: your unit is not mtcd type unit....so wrong forum
[MTCD Android Head Units General] rey_1178:
Is there a way to contact the developer of this app? There's a consistent bug with the px6 units for linkswell and phoenix where when using google assistant, the volume lowers and doesn't return to normal unless you trigger google assistant again.
[MTCD Android Head Units General] marchnz:
What have you tried. Is your unit MTCD type.

If you really want Android Auto or screen mirroring, these are Chinese origin head units are not it.
[MTCD Android Head Units General] Aeonxul:
Hey guys, I have an MTCE headunit running stock Android 9 with a rockchip px30 processor (2gb ram).

Anyway, I was trying to launch Android Auto. After some searching, I enabled the 'carplay' option in the other tab of the unit's factory settings but the zlink app was still hidden after a restart and even a factory reset. I extracted the apk using apk extractor and installed the apk over the existing one. However, I receive the channel mismatch error when the app launches. I installed newer version (4.0.32 i think?) But I still receive the same channel mismatch error. Is there anyway I can make the app work? (I want to launch AA when connecting my phone to the headunit.
[MTCD Android Head Units General] ikerg:
In order to get zlink working you must have compatible hardware . Did your unit come with zlink working? If not, I don't think you could make it work as it looks for specific hardware (that is normally built in into motherboard or by means of external dongle).

For the channel mismatch....Where did you find that version. In this thread?

Looking to your rom.version.....is some.kind of customized rom? Zlink looks for.something particular in the rom to identify the channel (the Rom must be made by hct)
[MTCD Android Head Units General] Aeonxul:
I understand. I thought maybe mine has built-in hardware support. I got the car second-hand and this unit was already installed but I don't think zlink was ever activated on the unit.

Yes, I downloaded the apk file from this thread and I received a channel mismatch error. Before that, I extracted the original apk (ver 3.3.19) and re-installed it to unhidden the app but I still received a mismatch error.

Well, it is possible a customized version of the rom has been installed by the car manufacturer (this is the factory-installed unit). I am willing to flash another custom rom but I don't want to lose the car features that I already have on this rom (TPMS app, door open/close overlays, AC overlay, etc.).
[MTCD Android Head Units General] ikerg:
That car features are governed by the canbus. What is important is to check which canbus is configured on your factory settings. Software for mtcd/e units is common based with some difference In launchers.

Would you mind to post some photos of the system? I mean some screenshots of the launcher...etc...

Here you are a Russian forum with all the information about px30 units. The latest firmware they have is from last November

[MTCD Android Head Units General] Aeonxul:
I see. Does MCU act as the controller of the canbus?

I have attached some photos of different menus such as home screen, car settings, factory settings, app drawer, A2DP Bluetooth, etc.

Also, thank you for introducing the Russian forum. I am actually already a user there and saw the thread but since I have to use Bing or Google translate, some parts are not really clear and I thought if I could activate zlink without changing the rom then I will be happy for now.

[MTCD Android Head Units General] iagobkstar:
I know it's just a workaround, but if you tap the voice assistant key (or say hey google) and, when you hear the google assistant beep, tap the key (or touchscreen) again, it goes back to normal. It's been like this since I remember. The latest version (4.0.37) is way faster at start listening and going back to normal after, so I strongly recommend you to upgrade - I haven't seen any added bugs in this version.
[MTCD Android Head Units General] Solubel:
Thanks for the links. Great! Hope they will work for the TS9 headunit running on android 8.1.0

Hello I recently purchased the Dasaita 10.2 px30 rk3326 HU and installed it and everything works fine except the zlink. I followed the instructions in the manual but zlink will not install. An error message appears that says “app not installed”. How can I get zlink to work?
[MTCD Android Head Units General] Nitz30:
Hi guys, I purchased an android head unit for my 2017 Nissan Rogue, it works fine but i'm suppose to have a built-in Carplay with, as of today i didn't know I will need Zlink app to make it works, like the seller just told me

So, it's a Sinosmart, with Android 9.1. 10.1inch screen 4Go ram, 64 Go rom, CPU: 8 core SC9853i,8*1.8 GHz

I tried both version of Zlink, the 3.5.24 and 3.5.37 and both doesn't want to install ..

But still not able to startup Android Auto, Apple Carplay works fine
[MTCD Android Head Units General] STRAIGHToutLAZY:
Can you pass me the link, I don't have that ver. yet

Thanks

unfortunatly I am also getting channel err channel miss match with the new app. I even changed all permissions
[MTCD Android Head Units General] rey_1178:
Thank you for your reply. At least I feel better knowing it's not just a me problem. I tried installing 4.0.37 but get an error. I think linkswell has to do something to the update to get it to work on these units. Latest version from them recently given to us is 4.0.18.
[MTCD Android Head Units General] iagobkstar:
Perhaps your unit is not MTCD/E? The same workaround has been working since at least 4.0.17, it's just slightly slower to do it
[MTCD Android Head Units General] Gatogol:
I bought a radio with android 10 that comes with zlink 3.6 and I realize that it can only connect wirelessly to iphones but not to android.

I have android and the truth is I would like to be able to connect wirelessly.

I've been reading the forum and I think that the zlink app can be updated but the truth is that I tried but it didn't work, I don't really understand the subject of datas, root, flash and things like that either.

I think that if you can connect wirelessly to iPhone you would also have to connect to Android

Could someone tell me how can I do it?

please I need help
[MTCD Android Head Units General] ikerg:
No you can't. The type of zlink is related to your hardware or the license (which is tied to your hardware) when you start zlink, some.icons on the lower right of the screen shows you which kind of connections are accepted.

Even upgrading your zlink app you will never get additional connection types than the ones you are getting now
[MTCD Android Head Units General] ruinertt:
That's not entirely true. When I first got my head unit, the zLink version didn't allow for wireless AA. There were only (3) icons if I recall. However, after upgrading it to a newer version that option appeared (more icons on the bottom right).
[MTCD Android Head Units General] Gatogol:
Hola amigo, ¿cómo puedes actualizar zlink? y después de la actualización, ¿lograste conectarte al auto inalámbrico de Android?

Hi friend how could you update zlink? and after updating did you manage to connect to Android wireless auto?
[MTCD Android Head Units General] ruinertt:
I updated it with the Android 10 Update from Dasaita (that is manufacturer of my head unit). It was pre-packaged in the update.
[MTCD Android Head Units General] Gatogol:
In my radio it does not give the option to update, it already comes with android 10 and in zlink it does not give me the option to update Can I update Zlink in another way, to have wireless auto andorid?
[MTCD Android Head Units General] ruinertt:
No idea. Maybe find the thread where someone has the zlink app extracted. As far as updating, go to the homepage of your manufacturer and/or talk with them. Dasaita keeps making updates, so perhaps your manufacturer does as well.
[MTCD Android Head Units General] iHusky:
Can someone help me with this issue, Ihave stock ROM
[MTCD Android Head Units General] alfajac:
Hello

I've just made the update of my Oppo Find X3 Pro to Android 12.

Now when I plug it on the android radio + Zlink, i can't see the map as all buttons has been magnified ... have you already met the problem ? Solved?

Where is it possible to get the very last version of Zlink please ?
[MTCD Android Head Units General] ikerg:
@iHusky I don't know where you get that stock rom.

Did you wiped all data prior to update?

What is clear is that you don't have a mtce unit (the ones in which the zlink channel is hct) but the zlink app corresponds to a hct type unit.
[MTCD Android Head Units General] ikerg:
Check if your zlink settings are in HD mode.

Go to settings on the initial screen of zlink and push on settings and scroll.down for options
[MTCD Android Head Units General] alfajac:
Hello thanks but it wasn't this.

I had a mega big parameter button + the field to type the adress in the middle of the screen.

I found the solution :

Update the Android Auto application on the phone,

delete the applications data

Restart the phone

On the android auto radio : delete the application data.

Restart the radio.

Connect the phone to the radio ...That will be considered as a new connection to be set ...

=> problem solved... back to normal display.
[MTCD Android Head Units General] ToyotaJay:
I never knew there was option scrolling down thanks very much.

I was using the other method with Headunit Reloaded App but there was a huge GPS delay , Have not tried in HD mode so hopefully no lag. Nice to have Wireless AA auto . Anyone else find Wireless Car play way smoother?
[MTCD Android Head Units General] PhantomTaco:
Hey guys, I'm curious about where I might be best off looking around for a zlink update/apk compatible with the UX999 pro. Anyone have any suggestions on where to start because it seems as though the app might be locked/based on the unit it's attached to?
[MTCD Android Head Units General] Rampire:
Hi,

Trying to set up Android Auto with ZLink 5.2.8 app that was preinstalled on an Android head unit. It used to constantly show "connecting" after plugging in the phone. Interestingly, the phone had already added the head unit to the connected devices in the AA app. As means of trial and error I have cleared the app data for ZLink, and now it doesn't go past the initial screen. Any advice?
[MTCD Android Head Units General] marchnz:
This forum is for MTCD types. If your unit isn't an MTCD type, you're posting in the wrong forum.
[MTCD Android Head Units General] CyrusMzRG:
Hello guys how are you?

I have a small problem with ZLINK app because I try to map my control wheel steering buttons into ZLINK but as soon as I turn off the car, the mapped keys are not saved and I need to map them again.

Anybody know how can I save them FOREVER? I dont understand why they are deleted.

Best regards
[MTCD Android Head Units General] ikerg:
Why you need to remap keys?

On mtce units....you map steering wheel keys to the behavior of the android system for which most (not all) functions are covered between car and android system that are projected to zlink when carplay/android auto mode
[MTCD Android Head Units General] CyrusMzRG:
Because I tried to map "accept a call" and "End a call" in Dasaita mapping key function and it doesn't work. If I map Tham un ZLINK it works, but as soon as I turn off the car the mapped keys erases.

Those are the functions are now missing in my steering wheel. Volumen + - , next/prev song, are correctly mapped by default
[MTCD Android Head Units General] ikerg:
If you have canbus .... Mapping keys are preprogrammed and you cant modify the preprogrmation unless you change a setting on factory settings in which you should reprogram all the steering wheel buttons which will be projected to zlink with same (or similar) behavior under carplay/android auto. Perhaps you need to remap all keys
[MTCD Android Head Units General] CyrusMzRG:
Yea. I think now is set in “CANBUS” do I need to set to SWC or something like that?? Then map the keys into wheel buttons app in Dasaita???

Thanks
[MTCD Android Head Units General] ikerg:
Yes
[MTCD Android Head Units General] CyrusMzRG:
I will try...but what about the native car functions actually mapped in the control wheel? like cruise control??
[MTCD Android Head Units General] ikerg:
As far as I know....I can't map all the steering wheel buttons...as part.of them are reserved for car specific functions....only some buttons can be mapped (based on key1 or key2 wire connected)
[MTCD Android Head Units General] CyrusMzRG:
I mapped the buttons, but they dont work under ZLINK app

Hey guys,

I have bought a SNAPDRAGON Android 11 Headunit for my Mercedes W166. Unfortunately the HU is not linking with my phone. As soon as ZLINK Starts and asks to connect via Bluetooth or Cable (I am connected via Bluetooth and Hotspot) I can only see a black screen.

Original NTG 4.5 Menu is working. Just the linking with my OnePlus 9 Pro is not working. Can someone help?

[MTCD Android Head Units General] smittysmitts:
Not sure where the problem lies, but when Android Auto/Z-Link keeps crashing for me.

Using a Dasaita PX6

With my OnePlus 6T,

latest version of Android Auto (7.3.620542), latest version of Z-Link, (from this thread)

With USB

Also recently got a AA Wireless dongle and still the same issue.

With my iPhone 13 on the same system no response from Zlink at all.
[MTCD Android Head Units General] ikerg:
I would recommend you to reflash with fresh ROM and try from there is the Link issues are still occurring....

Hoy did you do the uograde of zlink?
[MTCD Android Head Units General] owjezaman:
hello guys

does anyone can help me to download zlink app ?

I have searched around the internet and could not find it
[MTCD Android Head Units General] iagobkstar:
Did your headunit come with Zlink preinstalled? If not, you're out of luck - you cannot install it as it requires some sort of licence/specific hardware only the manufacturer can issue.

If your radio is an MTCD/E unit and Zlink came preinstalled, you will find an updated .apk in this thread, with instructions of how to install it (at your own risk!).

If it's not and MTCD/E unit or your radio did not ship with Zlink preinstalled, save yourself the trouble; the .apk will never work with your radio.
[MTCD Android Head Units General] smittysmitts:
I just downloaded the app and installed it as a regular side loaded app.
[MTCD Android Head Units General] MagnifyShay:
Hey, I've got a Bunsen head unit, do you know how can I check if it is MTCDE/E ? Also, what is it / what does it mean ?

Thanks in advance for the help :)
[MTCD Android Head Units General] iagobkstar:
It's the version of the headunit's MCU (microcontroller) you can find it in the "About my device/tablet" section under the general settings.
[MTCD Android Head Units General] owjezaman:
Thank for your answer

I have used it before but my car multimedia got in trouble and had to reset it ! So some of apps are deleted like zlink

Where can I find and download it ?
