First of all a big thank you to @surfer63 for this thread and all the underlying work! Actually it made me move over to FYT after having fiddled with MTCE for a couple of years, including root and mods - neither of which I need now. I installed my new FYT (reseller = Joying) in my MY19 VW T6 this weekend and am really pleased!

On the above point, my present solution is slightly different: I use AdAway pretty much as the only autostarting app for now. FYTstarter triggered a warning along the lines of "autostart of accessibility service requires root" - never mind. Uninstalled FYTstarter for now as this tool allowed me to call standard Android settings and unblock the autostart of AdAway. It now comes up nicely, I also made it an always active VPN (have no root). I think the tool may be worth mentioning in the Q&A as it also allows to modify apps re suspend (I "unoptimised" a few).

For me this is a great solution as I could pair my OBDLink MX without issues. Didn't even have to change the PIN in the (crippled) BT app. The MX was found and I could pair it (six digits confirmation code asked on radio). The only thing is it doesn't show as paired in the BT app (no phone anyway) but it works just fine. And it shows as paired in the Android standard settings, once you access them e.g. by using the above tool...

For me this uncrippling of my Joying was a major one - Mekede is not as accessible in my location (DE), the Joying arrived pretty much the day after ordering from EU warehouse...

Would be my guess also, as I ran into the opposite problem: I had to order my unit with the newer VW Quadlock harness and that comes with a disconnected "back" wire. Harness came w/o instructions and I didn't loop connect "back" when installing, just connected the cinch of the independently powered reverse cam. And there I was: Unit ignored reverse cam, didn't mute sound either, only PDC came up. Grrrr.

Everything else works well though, including the other stuff I carried over from the MTCE (third party USB DAB+, powered antenna splitter, etc.) - so it's been a good day :)
[FYT Android Head Units] surfer63:
You mean that you made AdaWay an active VPN? there are multiple open source adblockers who do that.

Or do you mean that Mario's tool can function as an always avtive VPN?

I will look into Mario's tool. This might indeed be a handy tool.
[FYT Android Head Units] Moldeb:
The first one is correct and I know many other adblockers work as VPN. My problem was that in AdAway's settings I could tell it to autostart but the radio then blocked that autostart feature so AdAway didn't come up. I fixed that by going to Android's standard settings and i) allow it to autostart plus ii) made it a permanent VPN. I could access the Android standard settings using Mario's tool...

Edit: Interestingly, Joying includes an apps autostart menu in the (newer?) firmware that allows you to select pretty much any installed app for autostart. However the selected apps autostart to foreground and I just want AdAway as background service. The menu may come handy for other apps though when it's ok that they get "fully started".
[FYT Android Head Units] Ajoalmejo:
Hi all. I have a strange issue with my Joying unit. Sound mixing doesn't work properly, but only when I use the default radio app (with music player it works as expected). When there is a message from navigator, the sound from radio stops, but the sound from navigator is very low (I can hardly hear it).

Anyone else has this problem?
[FYT Android Head Units] John RF:
I had that problem and wrote Joying's support. They suggested:

Select the default navigation app in Settings -> General -> Navi App

Turn on the GPS Mix in Settings -> General

This does the trick for me. However, only for the app selected as default. If you open a non-default navigation app, it will mute the FM radio
[FYT Android Head Units] j-5:
Grrr...I cannot get ADB over USB to connect to my head unit.

My computer is USB-C only.

I did all the steps in Developer options...

no connection....what am I missing?

edit: I got it.

It was a combination of using the right cable (curious how many usb-c to A cables don't do full data) and using the correct USB port of the head unit (sadly, the correct port is the one in my glovebox connected to my forward camera because 50/50 and I lost the coin toss)
[FYT Android Head Units] Ajoalmejo:
Thanks for the answer, but this is not the problem. I have already the GPS Mix option activated, and it is working fine with other apps, the problem is only with the radio app.

I don't know if it is a typical issue in uis7862 units, or in Joying units, or it is a particular problem in my unit for some reason.
[FYT Android Head Units] marchnz:
What does the seller suggest when contacted for support
[FYT Android Head Units] John RF:
But my problem was also with the radio app only. Let me describe more clearly.

My favorite and therefore default navigation app is TomTom Go. But I also have HERE WeGo, Waze and Google Maps installed. For quite some time I was surprised that only TomTom worked well together with the FM radio app. When I used HERE WeGo, as soon as it played a sound, the radio app would mute permanently. I then decided to ask Joying's support and they recommended me to try and switch the default navigation app to HERE WeGo (while keeping the GPS Mix on) and that worked: HERE WeGo doesn't mute the radio app when it is set as the default Navi app. I then opened TomTom and when it played the first sound, the radio would mute permantely. I don't know what trick these units use to make the default Navi app work well with the Radio app, but from my personal experience that is a fact.
[FYT Android Head Units] Ajoalmejo:
I'm not sure if we are talking about the same thing. It is normal that the radio is muted (or the volume lowered) while the navigator is giving a voice message. When the message ends, the radio recover its previous volume. This is the expected behaviour. But, in my case, the radio is muted, yes, but the volume in the navigator is very low during message. When the message ends, the radio recover the volume as expected, but my problem is I can't hear the indication from navi.

Anyway, from the begining I have GPS Mix activated and Maps (the navigator I use) set as default, so this is not a solution for me.

I have partially solved the problem setting the navigation volume level at maximum in the factory settings.

Hello. I have burned this ROM

General question: does someone have that ui46 launcher for me? For a 1280x720 screen?

Sorry, almost forgotten.

Mine is 12V for AVDD and 80 for VCOM.
[FYT Android Head Units] DWilks:
Just incase you really mean "minimum of 70", you set the maximum value between (40-100). I have mine set at 30-96 as noted by the top green slider bar. Included is a better screen shot incase you have trouble with the less resolution of the before post of the screen. And make sure to "Save" the settings. Maybe someone else can help but that's it for me. Good luck!
[FYT Android Head Units] rilerale:
thanks

@surfer63 and @DWilks

thanks for help.

the brightness control does not work.

I give up.

I asked Joying to repair / exchange it
[FYT Android Head Units] surfer63:
The only thing to check yourself might be the flat cable between unit and screen. Is it correctly connected and are there broken strands?
[FYT Android Head Units] rilerale:
the IDE cable is ok
[FYT Android Head Units] rilerale:
Unfortunately, I have already opened the case and glued cooling pads
[FYT Android Head Units] j0hn83:
That doesn't look like an FYT Firmware.

There are other ums512 devices on other platforms and even though they have the same SoC (uis7862) the firmware isn't compatible between them.

There are TS10 7862 head units and QF001/Roco K706 7862(A/S) head units.

That firmware may belong to 1 of them?

Edit: actually looks like it might be just an extracted 6315_1.zip

I can see that 1 of the other firmwares linked in that repo also has an oem folder with fyt/teyes apps inside.

If it is then you would need to do quite a bit to get those folders in to a format acceptable for an FYT unit. Have a look at Marios FYT Workbench.

Is there an option for the button backlight/led always on? So far I only found this in the setting
[FYT Android Head Units] labkos:
Thanks
[FYT Android Head Units] surfer63:
Set the "backlight control" to headlights. Connect the light detecting wire to the ACC wire. As soon as you turn your contact, the leds will be on.

That's how I did it,
[FYT Android Head Units] Dekdek1:
Do u happen to know what that wire usually labelled as?
[FYT Android Head Units] surfer63:
ILL (from Illumination) or "small lights detect" or something like that.

[FYT Android Head Units] Specy01:
@surfer63 and @daviddosa that he also has the Peugeot 308 and could make the necessary checks.

My 308 has LED front daytime running lights. The on-board computer allows to turn them on/off according to the taste by always setting it on, or on only when the lights are on when darkness falls. I like to have them always turned on even during the day. I always keep the light selector on the "auto" (automatic) position so that the lights turn on at dusk, while the daytime running lights are always on.

For about a month, these daytime running lights no longer come on, despite the fact that the on-board computer is set to the option always on. I didn't remember fiddling with various options of my NaviFly M700, but I was almost convinced that an option I had modified on the M700 turned off my daytime running lights. Finally today I found the solution.

Playing on the options:

- GELNERAL/Backlight control

- GENERAL/lantern settings

Finally I have the LED daytime running lights always on even when the light selector is on the off position or on "Auto" position.

davidosa, please, can you check on your car (if there is still you have it and if you have these led daytime running lights) if you have the same behavior?

surfer63, can you add to the first post in the "FYT Setting explained" section, which by acting on these two options also go to change the behavior of daytime running lights. I think it might be useful to some. other users.

Thank you

I hope i was able to explain myself well despite my bad English.

[FYT Android Head Units] surfer63:
Is this only for the Peugeot 308 (or 3008), or also other Peugeot models and Citroen models (both PSA)?
[FYT Android Head Units] Specy01:
I'm sorry, I can't tell you, I only have the 308 and here I don't know anyone who has a Peugeot with a FYT. That's why I wrote the previous post, to get feedback here. Surely @daviddosa will give us some feedback

Hi, Can anyone tell me what freeq configures SPDIF? The order of the bits is also out of order, first 32bits, then 16bits, 20bits and finally 24bits. I understand that it regulates the SPDIF output, I have an amplifier connected by optical cable to the optical output of the radio. And then 16bits sounds better to me than 24bits, they sound dull, that's why I don't quite understand what this configuration modifies.

[FYT Android Head Units] louforgiveno:
Yes, your display is and recieves 1024×600. If you decided to add a screen and used the Output RCA that screen/monitor would get a mirrored signal of what is on the head unit BUT at 800x600 (not 1024x600)

I am using a device based on 7862(s).

I have a few questions:

1. Is it possible to replace the standard BT Phone Dialer with some more refined one? I have seen such versions that have, for example, microphone level amplification in the settings. My built-in microphone is just too quiet, and I don't know how to enter engineer mode to change mic level/gain.

2. Is it also the case with you that when switching from radio/spotify to BT Phone app, there is a volume increase (sound peak) for a fraction of a second? Is it possible to remedy this somehow? I am using the Agama launcher. Can it make any difference?

3. Is it possible to display pictograms from the front proximity radars while driving forward (gear D)? I only hear warning sounds when approaching an obstacle.
[FYT Android Head Units] mikemat.pl:
I have a much simpler solution ;).

Just add a line containing the UNIT manufacturer ID in the config.txt file at update time. As a reminder, many manufacturers specify ID=1

ro.build.fytmanufacturer=ID

[FYT Android Head Units] mikemat.pl:
I have a much simpler solution for setting the default launcher for any android unit ;).

To set ANY launcher as default, just set one parameter in config.txt file during update.

Specify any launcher name that contains an ERROR in the name after =, e.g.

ro.fyt.launcher = com.android.launcher5121

After the update, the system will ask you to set the default launcher. We then log in to WIFI, select Google Play and install the launcher we want to use.

The new installed launcher will be the HOME default launcher. When we click on home, it will open as default launcher.

Regards

Hello, did anyone tried to change the behavior when ACC is switched on?

The HU currently switches on when the ignition is on (key in 2nd position) and switches off when you switch the ignition off.

I do not like to use the options in the settings to keep the HU awake 3 or 5minutes after the ACC is off.

I know that in my car (Ford Mondeo MK4) it is done by the CANBUS module on the chinese HU and I would like to change the behavior by checking other CAN messages and do my own switching on/off.

Unfortunately that's the only sub forum and thread that's relevant to your unit.

This sub forum is for FYT devices which are a very different platform. Our settings are different to yours.

AHD supports 1280x720 and 1920x1080 (and sometimes a few intermediate resolutions) regardless your screens resolution. If your screen itself is limitied to 1280x720, it will only display at 1280x720, but the recorded video will be 1920x1080 if you want to play that on your PC or somewhere else.

Build in my M600S today and set it up.

So far it´s a great unit but I have a problem with the blitzer.de app.

Always when a warning comes in (by speak) the stock radio and the nav radio apps are stopping there sound. The second problem is that the sound of blitzer.de is comming to late, so i can hear only the half message.

Has anybody the same issue or maybe a solution?

With for example navigate with maps everthing is fine.

I use the MD-EDITION with FMC form @mariodantas and i´ve do not test it with original firmware if it´s important.
[FYT Android Head Units] surfer63:
Have a look if the Bliter.de is using Bluetooth output. It should not do that.

If it is using bleutooth output, there is always a delay from 50-500 milliseconds.

And if it should warn your for speedcams and it is too late, you are driving way too fast.
[FYT Android Head Units] le_mi:
Sure but I set the audio output to car speakers. On other devices, for example non FYT uis unit from hizpo or PX6, it works correctly. Anything is wrong with the audio focus.

Apologies, this thread is so huge now it’s hard to check questions haven’t been answered…

I think I have one of these… I’ll check for sure later but here’s my “wants”:

1) Adjust the cellular signal strength check timing - The 4G signal for my journeys is really patchy within short distances and I find that the unit drops down to HSPA+ but then doesn’t recheck the signal strength regularly enough To realise that 4G is back. So, I end up stuck at HSPA+ far longer than necessary. This is only a problem when I’m trying to download music to negate the need for speed in the first place. I’d rather It checked the 4G signal every 60 seconds.

2) There’s a system app called Touch Assistant that I want to erase from existence. I can’t stand it. I can force it to quit but it’s set somewhere to come back after a cold start. Do I have to go through using a laptop and ADB to uninstall this f**ker?

3) I haven’t fitted a reversing camera yet. I may never fit one. How do I stop it from showing the non-existent rear camera feed every time I reverse?

Thanks!
[FYT Android Head Units] Matt Devo:
2) open the app and uncheck all the options. Alternately, you can use a script run from an update USB to remove any system-installed apps you'd like to purge

3) if your software is new enough, there is an option under factory settings called 'local radar switch' - turn it off. Otherwise, simply disconnect the reverse signal feed from the CANBUS box to the HU - it's the wire 2nd from the black ground wire on the main black plug (trace it to the CANBUS box and remove pin from the plug there) labeled A5 below
