Well Im on PE 13+ for Poco F4, the Bluetooth problem i mentioned earlier fixed itself after several reboots.

The latest Carlink above did connect wirelessly but couldnt sustain stable connectivity..
[FYT Android Head Units] DexterMorganNL:
Yep that's a bug in Android Auto: just reed on the Android Auto support forum. On the moment I rather not use Android Auto.
[FYT Android Head Units] dark_knight_007:
You can try Xiaomi‘ s own carwith software.
[FYT Android Head Units] DexterMorganNL:
That isn't available yet within Europe, and in the end another Android Auto: probably, because Android Auto won't work in mainland China.
[FYT Android Head Units] dark_knight_007:
The CarWith is not available openly in mainland China, because it's in a test stage. This is a modified version in the shared link . If you want, you can test it. The newest MIUI in your phone perhaps has a complete funciton.

Can you

tell me how it should be installed. Thanks in advance
[FYT Android Head Units] Akerboom:
just install apk as update
[FYT Android Head Units] axel92a:
AA looks like this on vertical screen, any idea how to make it fullscreen?

Already tried to install latest version from this forum.
[FYT Android Head Units] vitdaika:
I have CarLink version 2.23.0228.0844 installed on my OledPro head unit.

Is it the latest version? Where can I find the apk file of latest CarLink?

Thanks!
[FYT Android Head Units] j0hn83:
My recommendation is don't waste your time.

The internal mic is useless and no amount of tweaking will make it useable.

The external mic resellers supply are cheap and I wasted a long time trying to tweak it so others could hear me without success.

In the end I bought my own mic and it made a huge improvement.

Recently I managed to connect my original car microphone and it is perfect.
[FYT Android Head Units] Patryk1101:
I have an external mic, but it's still quiet
[FYT Android Head Units] Patryk1101:
maybe some hidden menu in this radio where you can increase the sensitivity of the microphone

I wonder what manufacturer of this radio
[FYT Android Head Units] surfer63:
Like @j0hn83 already mentioned: Forget it. There is no hidden setting.

Connecting the external microphone while the internal has not been disabled, will even make it worse.

There is no hidden setting. Many technical users have already looked at it in the past years.

Disable the internal microphone, and if you have a builtin car microphone (or two), then if possible: buy a fakra to connect your car microphone to your unit.

Otherwise disable the internal microphone, use some external microphone and make sure it is correctly inserted with a clear "click".
[FYT Android Head Units] Patryk1101:
External connected internal disconnected already 2 microphones tested and the same
[FYT Android Head Units] louforgiveno:
Look through settings, can't recall the wording.....but volume mix or something like that.....it will have a window that shows volumes for bt audio, radio, navi etc. Turn up bt audio or any other relevant source......btw setting is from 0-10 and on my unit radio was at 9 and a few others were at 2.......
[FYT Android Head Units] Patryk1101:
thank you i will check and let you know

what is the manufacturer of this radio?
[FYT Android Head Units] louforgiveno:
From what i can gather it's a mekede m200s 2gb ram 32gb storage 1.6ghz octa-core (referring to the unit i have)

increase the microphone sensitivity increase?
[FYT Android Head Units] louforgiveno:
I don't know about increasing the mic sensitivity...

.just how to increase the bt call volume to balance it's volume like the radio
[FYT Android Head Units] marchnz:
Factory settings menu
[FYT Android Head Units] Matt Devo:
that's not correct, there is no mic sensitivity setting in the factory settings; only BT call volume. The only way to adjust the mic sensitivity is via the config.txt file. eg:

persist.btmic.gain=10
[FYT Android Head Units] Patryk1101:
But how?
[FYT Android Head Units] surfer63:
Search! Simply on persist.btmic.gain

It is mentioned at least 10 times in the forum.

And some more general reading as well might help you also to get some background knowledge.
[FYT Android Head Units] thericksizzler:
2.23.0224.1346 is this the latest version?
[FYT Android Head Units] surfer63:
I am not entirely sure about the versioning, but looking at previous versions I think it is.

Version 2 compiled on 2023-02-24 13:46

I downloaded this morning Mekede firmware 7862-A12-wbt-9-10.zip with a "Ver" file containing 2023-03-14 09:29:02, which is when the firmware was created.

The carlink version was compiled 2023-03-13 14:19 (so one day earlier than the firmware).

If my reasoning is correct, then your version is slightly older.
[FYT Android Head Units] thericksizzler:
Can you upload it please
[FYT Android Head Units] surfer63:
See attached.

zip removed as it is outdated.
[FYT Android Head Units] thericksizzler:
Can you upload it as an apk please
[FYT Android Head Units] surfer63:
As you wish, but it doesn't come for nothing with updated libraries as well. Only the apk might not be enough.

apk removed as it is outdated.
[FYT Android Head Units] thericksizzler:
I don’t know How to update with zip file.

I thought apk was enough.

Can I update it with zip like this?
[FYT Android Head Units] surfer63:
Use attached zip. Unzip it to a usb flash drive. It will install the apk including the libraries on a 7862 and on a 8581. The name version is the compilation date of the apk.

Installer removed as it is outdated.
[FYT Android Head Units] thericksizzler:
What is the difference between installing zip and apk? I am curious. Exactly, for example, what kind of differences occur when I install apk or install with zip.
[FYT Android Head Units] ShelbyRacer78:
Is this the latest version we know of by chance? I installed the files via USB and it seems like its still having issues.
[FYT Android Head Units] surfer63:
Sorry. I missed this one.

The zip only contains the apk and libraries. It is not simply something you can install without an lsec script. That is why I added that lsec scriopt later.

The apk as update is enough if the external libraries are not updated. In that case you can "simply" install the apk as any other update.

That is a strange question. There is nobody here that checks every hour for updates. This is the version of 13 March 2023. If nobody has checked all websites after that and found a new one, you can assume it is the latest version.

Next to that: "The real original" Android Auto offers split-screen since a few months. if the Chinese really add new functionality, like split-screen in the carlink app, they will absolutely inform their users about it and release/publish the new apk. Same for important bug-fixes.

Not correct: Please read @j0hn83's answer below in post #115.
[FYT Android Head Units] ShelbyRacer78:
@surfer63 I installed the APK for carlink for the apple carplay feature. The unit seems to be stuck on a verification approved loop

I have attached a link to a video of the issue

Video
[FYT Android Head Units] surfer63:
I have no idea. I only provided the apk to @thericksizzler

I don't have an iphone and I don't use Android Auto either.

I have a full-fledged 1280x720 uis7862 4GB/64GB powered unit which does support dashcam, DAB+, reverse camera, TPMS, etcetera.

Personally I think it is completely useless to use either Carplay or AA on such a unit.

You pay 200-500 euros for a great unit and you only use it as a frontend for your phone? For 99 euros you buy a unit which can do carplay and AA just as well.
[FYT Android Head Units] ShelbyRacer78:
I have the same MEKEDE M500S as you. I really only use carplay and sometimes OBD2 stuff. While it is kinda useless to only use for a couple things, it is better than the OEM radio that came with the car.
[FYT Android Head Units] j0hn83:
Coolwalk (split screen/cards) surprisingly works perfectly on the carlink app with both waze and Google maps. It was initially Google maps only but that was due to waze.

The car headlights even control dark mode.

I recall many posts here a few months ago asking about support for coolwalk but don't recall anyone saying it works.

The delay was purely on Google's end with coolwalk being slowly rolled out initially.

I drive another car with true Android Auto and as soon as Google marked my account as having the upgrade it worked on both cars immediately. Everything that works on the real thing works on carlink (that I've checked, I don't use it very often).

Edit: to add, I enabled developer options in Android Auto on my phone to disable wireless Android Auto. It's never worked for me. Every time I try it disconnects from the 5Ghz hotspot for a split second and it crashes. It works on 2.4Ghz but buffers online media.

I think I also fixed the resolution within those developer settings. I don't know if this makes any difference.
[FYT Android Head Units] surfer63:
Thanks. Not being an AA user, I didn't know this. I will correct my answer.
[FYT Android Head Units] thericksizzler:
I guess there is no way to reach the developers, right?
[FYT Android Head Units] harrez:
hey man , could you do me a favour of reuploading that update file (7862-A12-wbt-9-10.rar) to some mirror ?

[FYT Android Head Units] hzn942:
I wonder if carlink update can allow us to change DPI for android auto, the interface feels too small for my eyes.
[FYT Android Head Units] surfer63:
No, at least not at this moment. The program simply uses the default DPI.
[FYT Android Head Units] lovemx93:
I have another china android player and uses carlink too. It is android 12 and is on a 2022 version of carlink. The Feb 2023 carlink works well but is unable to keep connectivity if there is wireless interference e.g going through a carpark gantry. This is regardless of using android auto or apple Carplay. Was wondering if this march version will fix it or its the same ?
[FYT Android Head Units] j0hn83:
It isn't. If it uses the same carlink then it is an FYT and it is Android 10 with a fake flag to change the number.

There is no Android 11, 12 or 13 on this platform. Only Android 10.

I can just as easily make is say Android 99.
[FYT Android Head Units] lovemx93:
My bootscreen is showing android 12 though. isn't it too much effort to even change the bootscreen? But you could be right but I am more interested in whether the latest update is able to resolve the wireless interference issue. The moment it disconnects, it doesn't reconnect
[FYT Android Head Units] surfer63:
I can give you a script that makes it say Android 34 or 123, or whatever. Also very simple.

This is an extremely specific question I have not seen before, and as you are quoting me, I can only say: try it out.

You do not mention if it reconnects after xy seconds or minutes.

If it is a WiFi disturbance, the app can't help it. It can only try to reconnect. Maybe the developers could improve on that, if they did not already do so.
[FYT Android Head Units] lovemx93:
In case you missed out my message, it doesn’t reconnect at all. Seems like the app crashed. I am quoting because my android unit doesn’t support update zip I think and I am unable to do anything with the latest carlink zip you uploaded, and installing the apk itself has of no use at all. So was wondering if someone could bundle the libraries together in the apk, which I believe someone in page 3 managed to do it for the Feb 2023 version. Any help is deeply appreciated
[FYT Android Head Units] surfer63:
The mechanism of update.zip does not work on these units.

That's why we use lsec scripts to "push" something on these units.

I created that script for the 13 March version including the libraries, but I have no idea whether that contains the the bug fix you are requesting.

Please send an email to your reseller mentioning this bug and hopefully they will forward it to the "carlink programmer/team".
[FYT Android Head Units] lovemx93:
I didn't understand what I am supposed to do with the zip file. basically download and unzip to any usb ?
[FYT Android Head Units] surfer63:
Yes, but you need the zip from post #108. That is an installer.

However, that is no longer the latest version as the new Joying version is from 06 May. The post #108 version is from 13 March. I will remove it.

Edit: The new version comes with a new APK and a couple of updated libraries, but not all. The AndroidAuto library has been updated. The Carplay libraries not.

Edit2: For those who want to try. Please find the 06 May 2023 carlink version of Joying attached. It is a scripted installer.
[FYT Android Head Units] lovemx93:
I gave up. I went to my car accessories workshop and top up 30$ to change to a zlink version which has a better connectivity 🥲
[FYT Android Head Units] Syntaxer:
I have got my hands on version from 22 May but without the libraries.
[FYT Android Head Units] thericksizzler:
can you send it w/ libraries please.
[FYT Android Head Units] Syntaxer:
Unfortunately I do not have the libraries for it. You can try flashing zip from post #130 from surfer63 and then just updating the APK normally.

Also I am attaching newer lsec6315update for devices that complain about using old version during flashing.
[FYT Android Head Units] thericksizzler:
I guess that's not how it works. Libraries are changes for every update.
[FYT Android Head Units] Syntaxer:
The engineer over Skype sent me the APK without any libs and said to install it. My previous version was from February (it did not work for me as I got black screen during connection and then it returned back to CarLink app). I was contacting him regarding issues with Wireless AA as it disconnects few seconds after connecting (I can see maps and Spotify but then it just disconnects). It worked wirelessly like twice maybe due to right constellation of stars or something :D so I am using cable but that gets disconnected too sometimes, probably it is phone problem (MIUI 14).
[FYT Android Head Units] Akerboom:
My wife has the same issue with her poco phone with MIUI 14.

With my pixel 7 phone wireless works flawlessly.
[FYT Android Head Units] Syntaxer:
Then it might be phone issue, I have Poco F2 Pro. Wired AA seems to be working fine for me now.
[FYT Android Head Units] Matt Devo:
here's CarLink 2.23.0522.1924 w/libs (from AllAppUpdate.bin 20230602)
[FYT Android Head Units] thericksizzler:
Just updated. It feels like more smooth.
[FYT Android Head Units] Akerboom:
I flashed with new libs, now all it gives is a black screen and then forcecloses. and repeat. with both my phone (pixel 7) and my wifes phone. Wireless and with cable the same.

How can I fix this?
[FYT Android Head Units] Syntaxer:
Have you tried clearing Carlink app data?
[FYT Android Head Units] surfer63:
First: Which script or how did you install carlink with its libs?

Secondly: Please make a listing of your /oem/app. Sometimes the carlink apks have slightly different names (190000000_com.syu.carlink.apk or 19000500_com.syu.carlink.apk or 190043001_com.syu.carlink.apk) and then you suddenly have two conflicting versions.

So please make a listing and not by screenshots, but a proper linux listing. If you do not know how to do that, then please use my hwgetinfo apk. Next to a lot of other stuff it will also make a listing of /oem/app.
[FYT Android Head Units] Akerboom:

used the lates script with libs in this thread

[EDIT[

Just flashed the latest Joying firmware which comes withe the 6 May'23 release of carlink and all is good again.

After, I install the 22 May'23 update of carlink and it gives the blackscreen and forceclose again, so I removed the update. I don't dare to install the libs again.
[FYT Android Head Units] surfer63:
I don't know who's script it was 9as it mine??), but the access rights on the libs and subdirectories are incorrect.

The access rights currenlty are 700 for both subdirectories and files, but they should be 755 for the subbdirectories and 644 for the libs.
[FYT Android Head Units] Akerboom:
Yes, I thought your 5 may version script.

I thought the script created these directories, how could this go wrong?
[FYT Android Head Units] Akerboom:
@surfer63

The update script uses:

chown -R 0.0 /oem/app/190000000_com.syu.carlink
chmod 755 /oem/app/190000000_com.syu.carlink
chmod 644 /oem/app/190000000_com.syu.carlink/190000000_com.syu.carlink.apk

maybe this should be:

chown -R 0.0 /oem/app/190000000_com.syu.carlink
chmod 755 /oem/app/190000000_com.syu.carlink
chmod 644 /oem/app/190000000_com.syu.carlink/190000000_com.syu.carlink.apk
chmod -R 644 /oem/app/190000000_com.syu.carlink/lib
[FYT Android Head Units] surfer63:
No, the script should be (at the end)

chown -R 0.0 /oem/app/190000000_com.syu.carlink
chmod 755 /oem/app/190000000_com.syu.carlink
chmod 644 /oem/app/190000000_com.syu.carlink/190000000_com.syu.carlink.apk
chmod 755 /oem/app/190000000_com.syu.carlink/lib
chmod 755 /oem/app/190000000_com.syu.carlink/lib/arm64
chmod 644 /oem/app/190000000_com.syu.carlink/lib/arm64/*

As the shell interpreter is so limited, I do not know if the chmod understands the more complex parameters.

And I am curently on holiday and can not test myself.
[FYT Android Head Units] solteq:
Could You upload working libs & carlink app from this release ? I also have black screen and try to fix it.
[FYT Android Head Units] Mastef76:
Hi, I downloaded everything but then it asks me for a keyword and it won't let me continue. Which? Thank you
[FYT Android Head Units] surfer63:
Now you are hijacking this thread. Don't do that. This is only about a carlink update, not full firmwares.

And I don't understand what you mean. What keyword?

And if you mean password, there is no password.
[FYT Android Head Units] solteq:
Maybe to extract allappupdate.bin
[FYT Android Head Units] surfer63:
OK. In that case @Mastef76 should not ask but search and read the forum. Read "General FYT based Spreadtrum uis7862(s) (unisoc ums512) & uis8581a (sc9863) - Q&A, Mods, tips, firmware", post #1 and #2.
[FYT Android Head Units] Mastef76:
Maybe I misunderstood, I'll rephrase the question, since android auto doesn't work on my device, I wanted to use easylink which was previously installed before performing the current update. is there any solution or other application to display the phone on the car stereo? Thank you
[FYT Android Head Units] surfer63:
easylink (in the menu and the launcher) is called carlink in the AllAppUpdate.bin.
[FYT Android Head Units] laoyang88:
I still wait for you to come back from vacation and test it correctly before updating
[FYT Android Head Units] ebrahimalsayed:
how did you update it? also is there a way to add the lib inside the apk?
[FYT Android Head Units] surfer63:
Ever thought of doing it yourself? I am not your personal servant. The magic word "please" also can help. You could have unzipped the file, use my modifications (post #148) and rezip it.

I am not even using it myself as I don't use Android Auto.

Anyway, see attached as I assume others might need it as well. The carlink 22 May 2023 version (compilation date, not file date) is still the latest (in my posession at least)
[FYT Android Head Units] Mastef76:
Hi, I downloaded your file and put everything on a usb stick. Could you kindly show me the installation procedure on the car stereo? Thank you
[FYT Android Head Units] j0hn83:
Extract the files to the root of a USB stick that is formatted as FAT32.

Connect the USB stick to 1 of the head unit USB ports.

A message will appear telling you firmware is detected, hit start or wait a few seconds and it will start the flash process automatically.

Wait for a few seconds after the green text shows that flashing was successful and remove the USB stick. The unit will reboot. Job done.
[FYT Android Head Units] Mastef76:
ok done installed. Now which app should I install on the android phone?

The operation will then be via wifi or usb thanks
[FYT Android Head Units] surfer63:
# Deleted. Already answered by @j0hn83 #
[FYT Android Head Units] surfer63:
You need Android auto on your phone.

And you need to couple it via bluetooth.

With Android auto all phone calls go via A2DP via BT.

All screen actions go via WiFi-direct or via USB (because BT simply doesn't have the bandwidth to support complete video streaming).

Edit: sorry. When rereading I thought that could not be right. Phone calls do not use A2DP but HFP (Hands Free Protocol) in AA.
[FYT Android Head Units] Mastef76:
android auto is already installed on the xiomi phone but I could not connect it both in wifi and usb. It connects only if I open the carbitlink App installed on the phone, it connects but it doesn't let me interact from the car stereo but only if I scroll on the phone! I don't understand what I have to activate to activate android auto on the car stereo without using carbitlink which is paid and only a demo already installed in the car stereo thanks.
[FYT Android Head Units] surfer63:
Because you have a Xiomi.

Your phone uses a wrong channel. See here and here.

Next time search the forum as you are not the only one trying to use AA.
[FYT Android Head Units] marchnz:
^^^^^^^^^^^
[FYT Android Head Units] Mastef76:
nothing to do, the 5g the car radio does not accept it is detached in hotspot

I can only set it on 2.4/5g phone

That's why I can't connect it with this Car Link 2.0 app

Other solutions?
[FYT Android Head Units] surfer63:
USB cable. Much more stable as well and it will charge your phone at the same time.

Or simply use the unit as it is intended to be used: As full-flashed expensive, fully configurable Android unit being able to run all kind of apps, also in splitscreen.

Like I already said: I don't use AA.
[FYT Android Head Units] Mastef76:
the problem is that it doesn't even connect with usb! The App installed car link does not see the phone by opening the android car from the phone. Excuse what it means that you don't use AA

Things.
