I don't care how the Chinese do it, because the end of the day I'm not willing to buy a new car: just so that I get AA, which I'm sorry. I'm finding it very useful, now that I have set it up to start fully automatic.

There is an project called OpenAuto, you can install it on MiniPi computer and setup a head-unit. But that's a pain in the ass, so I would pick the solution from our Chinese friends over this.

GitHub - f1xpl/openauto: AndroidAuto headunit emulator

AndroidAuto headunit emulator. Contribute to f1xpl/openauto development by creating an account on GitHub.

github.com

And if I would pick any aftermarket Carradio which has official support, than I would have ended up with an JVC unit for € 300 not even capable of native navigation. I like to be able to make a choice, with the Android headunit I can also run Google Maps or any kind of navigation app from the headunit.

( This UIS 7862 based headunits, are a bit cheaper than € 300 )

Another thing with the official Android Auto support, on headunits like JVC: the screens are really poor quality, they are 800*480 TFT screens. Oh and Android Auto wireless? Forget about it, and especially the wireless is why I opted for Android Headunit.

Btw all Android Auto works with an app, built-in at the headunit: you can't even get it automatic with those official units, because you always have to press the app icon. But I able to get it automated on my headunit, without even having to use a tasker.

So I would say, it's just an unofficial/not supported by Google: but what matters is the end result, and that's 100% real Android Auto displayed on your headunit.

[FYT Android Head Units] marchnz:
Call it Kevin, it's not AA, and has its own set of bugs which are constantly discussed and misunderstood for AA here.

If you want real AA probably best buy a sanctioned aftermarket AA headunit - but why anyone would want "AA" on full Android is beyond me - just as you state.

Leaving this here.
[FYT Android Head Units] DexterMorganNL:
I don't get these discussions? What's wrong with Android Auto or Apple Carplay, if you happen to have enough cash to buy one of these. And what's the point of calling it fake AA or whatever you are doing?

Anyway it's AA which is displayed on my headunit, so it's not Kevin. It's AA, and it's made possible by Carlink. How the Chinese developed it? Don't ask me, perhaps they stole some source code from OpenAuto or whatever.

The reason I wanna run AA on my headunit, is because Android isn't optimalized for using inside a car. It was developed for use on smartphones and tablets, and you can notice it within the interfaces of apps.

Where as AA is, so I find it pleasing to my eyes. To have an car friendly interface, whereas native Google Maps isn't, although I'm generally satisfied with its interface.

Which I use from time to time as well on the headunit, will only display a very small control widget for Spotify. But in Android Auto it's like 60% Google Maps and 40% Spotify, and if I receive any WhatsApp message. Than its partly show to me.

But also: when I searched a route on my phone, I can start it. Get into my car, drive off and before I know its displayed on the screen and it starts playing music. So way more convenient, than getting into the car: opening Google Maps, waiting for WiFi to connect. Clicking on the recent searched location, and start the route.

That's very useful for when doing a longer journey, but for the shorter trips I prefer convenience over using the built-in navigation. Even with MacroDroid, I would still have to wait for the WiFi to connect.

One quick one, is it possible to change Carplay to right hand drive on an FYT unit?

Most headunits have an option that mirrors the UI, but I haven't found it for my new Navifly 7862 yet.

edit: Never mind, it's in Factory Settings > Drivers Door Position.
[FYT Android Head Units] DexterMorganNL:
It's probably a setting within Carplay, or doesn't Apple allow it? Within Android Auto, I have such a setting.

Hello,

I have Mekede M300s (FYT 116) 3/32 unit, besides the small bugs I am happy with it except one thing you may be able to help me out. I share the internet to the unit from my phone as a hotspot and everytime the unit boots wifi connection is delayed by several seconds (wifi auto reconnect is ON in the wifi settings). If I set autorun for Spotify or Waze navigation the apps just freeze as they need network connection before loading.

And the question is: Is it possible to prioritize Wifi and BT connection during or immediately after boot somehow? I read on @mariodantas website that there is a possibility to launch a service, but how can this be done for Wifi?
[FYT Android Head Units] mariodantas:
It is not an automatic possibility, it means that if you build some app which waits for thhe Android BOOT_COMPLETED event to launch, it should be whitelisted here
[FYT Android Head Units] roti86:
Ok, I understand. Any other method for the wifi? I found this question here, but I do not really know what I should modify.

[FYT Android Head Units] voxmagna:
Thanks for this but I have a couple of basic questions which others may ask. I have a LEHX Chinese unit Model ums512-1h10-natv running Android 10 API level 29 and UIS7862 CPU. The build ID is oP1A.190711.020 release-keys. I cannot get a rom image from the vendoe although their UI looks very much like Joying.

I've rooted several phones and installed TWRP but TWRP is manufacturer specific and unknown for this device. My strategy to root is to try to backup the original firmwar first and the only way i've read is using ADB. But this unit has 3 USB ports which appear to only become active at a later stage of boot. Inserting a flash stick with an exe to run a script won't work.

I've tried to force it into the standard Android revovery but just see the bootloop icon for 3 seconds with message no data then it boots normally which makes me wonder if it has a recovery partition at all although it does have a 'factory recovery' in their UI.

Without a safety net of the original factory image my options seem limited to backup via ADB if possible, rooting, then use Titanium App. But can I establish an ADB link to the head unit when none of USB ports seem to be polled first

I have a Chinese LEHX unit Model ums512-1h10-natv Build ID OP1A.190711.020 release keys, CPU UIS7862 running Android 10 API 29. It has 3 USB ports and none will see a flash stick with an exe to run a script and backup the original firmware which I won't get from the vendor. The API looks very like Joying. There doesn't appear to be the standard Android recovery partition although there is a factory recovery option built in which works. There won't be a custom TWRP for this unit which is the way I have gone with Magisk in the past, so I'm left wondering how I can get a no risk firmware backup first before considering root and a backup app like titanium? After several button combination presses I did see the Android Boot logo saying no data for about 3 seconds, then booting completed normally. At the moment their 3 USB ports only seem to come alive well into the boot phase so I don't think I can link to a pc and use ADB? I've rooted several devices before but not head units. I suspect this one has a boot image that is very customised from what I'm used to in phones. It has its own customised Launcher too, could this be part of my problem? I did try installing a second generic launcher which 'worked' but home screen icons were too small and wouldn't scale up without pixelation.

Any ideas to get past this backup hurdle would be appreciated because I suspect many others may get a similar problem - How to safely achieve backup/recovery of the OE firmware before doing anything else?
[FYT Android Head Units] surfer63:
It is indeed one big hack but based on Android Automotive which is open-source and SHOULD run on our units. However the Chinese continue to not use the Android Automotive HALs, but their own closed-source firmware, but thereby at the same time forcing them to make something like the carlink app, simply copying those Androud Auto functions from the Android Automotive project.

(NOTE: Android Auto is not the same as Android Automotive. Android Auto runs on your phone. Android Automotive is Android for your car unit and supports Android Auto)
[FYT Android Head Units] surfer63:
That is exactly why Google and others developed Android Automotive for your car head unit. The fact that these Chinese hackers are using a standard Android with their own closed source drivers makes the experience less than optimal.

If they would simply use Android Automotive you did not need Android Auto (or CANbus controllers, which mostly work but never 100%)
[FYT Android Head Units] DexterMorganNL:
I read though, there is a developer who got Android Automotive to run on his Android tablet: I quickly searched on, and indeed it's Android as well.

But I'm guessing, we are never going get it with our units: instead we have a crippled Chinese version, that they put on top of Android.

In a way, the Chinese built their own Automotive part which they have added to our headunits. Some work quite good, like the reverse camera. But the FM Radio is really crippled.

Can anyone confirm what the plug needs to be for an external microphone on the FYT units?

TS, TRS or TRRS?

Or supply a photo of their plug if easier!

What's the point of this Digital Wellbeing App anyway? Isn't it meant for smartwatches and stuff like that? So we wouldn't even need it on our units, unless you wanna Sync your smartwatch with the headunit.
[FYT Android Head Units] surfer63:
Yeah right, but according to statista there are now 6.6 billion smartphones on Earth. And how many head units? We are too insignificant to make an exception on the general "standard roll-out" policy.

The sleep times, Sssh-times, etcetera, should definitly not happen when we are driving.

Hi everyone!

I am new user with head unit of UIS8581A combine with android 10, I am facing with error when try to back up from Car launcher pro or Power amp to local storage, or restore a backed up files from local storage...

This is alarm when back up setting of Power amp equalizer (some other app has almost same error):

I tried to install ''DocumentsUI-10.apk'' to solve it, that error no more appeared, but every time I try to back up, the app crash notice appeared and I still cannot back up anything to local storage, I attached the log file of the error and my hardware infor.

Could someone take a look and guide me to solve it plz.

Thank you so much and sorry for my poor English.
[FYT Android Head Units] surfer63:
Did you also try to use a 3rd part file manager to create a folder or save a file on your external USB-disk? Can you use the builtin file manager to save to local storage?

And where does poweramp stores its backups? in a user selecatable folder, in a standard folder, in the root of the USB-disk?

If it writes to a standard poweramp backup folder, can your try to precreate the folder with a 3rd party file manager or the builtin file manager?

Finally: your logcat is 42.984 lines. I can only do a quick search on such a massive file.

poweramp is using the documentsui. Not only that: when using it the log mentions

ActivityTaskManager: ->startActivity for ActivityRecord{8ce7d65 u0 com.android.documentsui/.picker.PickActivity t5145} result:START_SUCCESS

And then you get a series of messages and errors where the most important one is:

ActivityManager: Permission Denial: opening provider com.android.externalstorage.ExternalStorageProvider from ProcessRecord{5379d54 9746:com.android.documentsui/u0a127} (pid=9746, uid=10127) requires that you obtain access using ACTION_OPEN_DOCUMENT or related APIs

So somehow the documentsui.apk doesn't have access. Did you at least start the documentsui.apk itself, before trying to use it with other apps?
[FYT Android Head Units] danilaur:
hi,for isudar v72 why i cant add themes app ?

you can fix ?

thank you
[FYT Android Head Units] quangtiens:
Thanks for your quick response.

Actually built-in file manager and many 3rd file managers are run as normal without any problems with internal and external storage.

As usual Car launcher pro will save file in internal storage and Power amp will let's us choose where to save the file.

BTW, may be problems is from Documentsui apk file is not compatible with the rom?!

I said that because of after install the file, I clicked on it first time then nothing happened, clicked on it second time, the file crush notice will appear, I have tried to restart head unit, re install the Documentsui file that has downloaded from other sources... But always same result.

Plz you see the photos of the error for more detail:
[FYT Android Head Units] surfer63:
Completely wrong sub-forum. You have a completely different cpu/mcu and firmware set. Try the android head-units subforum.
[FYT Android Head Units] surfer63:
No, like I mentioned in my previous comment: the app is started correctly. No problem.

But the documentsui.apk itself doesn't have access.

In a file manager an overlay is created to use the documentsui.apk to select in the file manager access to external storage.

I have the idea Poweramp is directly trying to write using the documentsui without the intermediate step of selecting and requesting access.

I am now thinking that the only possible solution is that the documentsui.apk should be part of the firmware and reside in /system/app or system/priv-app. This would require you to rebuild the complete AllAppUpdate.bin. Use the one you had, add documentsui.apk and only flash that WITHOUT an updatecfg.txt (read post #2).

But as started this paragraph: "I am now thinking that the only possible solution....".

I don't know as I have not seen this before.

And did you already ask on https://forum.powerampapp.com/ ?
[FYT Android Head Units] quangtiens:
Ok, I will try will AllAppudate.bin and hope it can solve my problems.

I have not ask in Power amp forum yet cause of I think it is Rom's problem, it is not app's problem...

Thank you.

[FYT Android Head Units] DexterMorganNL:
Does someone know, how you can avoid the time and date to be reset everything? I tried deep sleep, but didn't drive the car for 6 days and today I went into the car. Put on ignition, to make a note.

I discovered that it shutdown, and was not in deep sleep anymore: so time was 3am in the evening. It's set at network time, would it work to put that off? Because it's a bit annoying that time and date keeps resetting, it messes up with apps and Android Auto when the time and date is wrong.
[FYT Android Head Units] leo06:
You can set the time manually on the settings
[FYT Android Head Units] surfer63:
That is not the point that @DexterMorganNL is making. Of course you can set it manually, but it should not be necessary.

It is indeed terribly annoying that date and time is completely lost if the unit goes "out" after 3-4 days of deep sleep. If it wakes up and gets a wifi signal, it will automatically update again: no problem, but if you don't have a network signal or a phone to connect to via BT, your date/time is completely off.

And sorry: I don't have an answer and it is also for me one of the most annoying shortcomings of these units.
[FYT Android Head Units] leo06:
If you set it manually also resets after shutdown?

Question: if you go to bluetooth scan setting, the Bluetooth devices are shown with their name or with ”NoName” ? I am trying to connect a Bluetooth led strip controller and I can’t see it with its name, instead all non connected devices are shown as NoName.
[FYT Android Head Units] DexterMorganNL:
So I guess, the best is to still have the unit get the correct time from the network? I noticed, that it would also gets the correct time and date when Android Auto wireless is setting up this wireless 5Ghz connection it uses.

But mostly it won't connect on the first try, when the time and date is wrong on the unit. I haven't tried setting the time and date manual, but if it than also resets the time and date. Than it would be even worse, as you would have to correct it manually then.

I'm really struggling to get an external microphone working on my FYT unit.

The internal one worked (although obviously didn't sound great) and I have successfully disabled this using the tape mod on the ribbon cable.

However, I am not picking up any sound from the external microphone. I have tried both TRRS and TS terminated microphone cables with no luck.

Investigating the back of my unit, the mic cable is the one dotted in purple on the attached. I notice that the yellow cable goes to the plug, while the black one appears to go back up one of the other cable sleeves. This doesn't look right to me - can anyone compare with their own FYT cable loom to confirm if this is normal or not? Many thanks.

Hello,

I have a headunit based on this SoC. It uses TDA7851 amp IC and 8761btv BT module.

Audio quality from FM is fine, but from bluetooth streaming and carplay, sound has absolutly no bass and sounds pretty awful. Like somewhere treble was set to max or something. Anyway to fix this or are these units generally believed to be this bad?
