It won't prompt you for the code. You'll need to pre-enter it on the the options screen in the phone dialer/bluetooth app, furthest icon to the right side (I believe it looks like a "gear" icon).
[Android Head-Units] itiswitis:
If all fails, disconnect battery.
[Android Head-Units] MauriBixio:
Disconnecting the car battery is of no use in relation to the factory reset of the HU!

It is equivalent to doing a common cold boot of the unit.

If it doesn't work in the ways we wrote, the unit is defective or anyway the Android OS is "defective" for some reason...
[Android Head-Units] itiswitis:
Maybe I misunderstood, but previous post said they tried "restart" through menu and pushing the physical reset button, but button was not working. This sounds like they want to reboot the unit as opposed to a factory reset.
[Android Head-Units] afeldman:
Good afternoon.I have a S5 model and a Samsung S21 ultra phone. I went on vacation for 15 days, and when I came back the Bluetooth connection was no longer the same, and I can't connect to android auto. I did a factory reset, and it didn't work. Now I think the problem comes from the phone itself after a UI update. Although I'm not sure about this.Previously it connected seamlessly and immediately wirelessly when starting the car. Now it connects to Bluetooth on the phone indicates that android auto is searching for a screen, but never connects. If I'm not mistaken when connecting now it only says "connected" but before it said "connected with multimedia" or something like that. In the phone's Bluetooth settings, sounds, contacts, and calls. If anyone had this problem and can help me I will be very grateful.

I need to know if during your travel NavRadio mute or mix the audio(according to your navi settings) correctly when maps tell you the direction and of course the audio come back just like the original app.
[Android Head-Units] marioti:
From the beggining I have setted mixing audio navi to 100%, meaning navi doesn't mute eg. radio.

But for the test i'll change that and see

Hello! I have an S8 head unit, it doesn't speak the TTS voice all the way through (Hungarian) The language input is set to Hungarian, the vocalizer is installed (avicsync navi) what could be wrong?😯
[Android Head-Units] itiswitis:
Also need to turn off voice in the same settings page. Options are counter intuitive: Disable Floating Icon, Enable Voice Disable.
[Android Head-Units] fitti2:
Thanks, I'll try! By the way, where can I find the text-to-speech setting, the language is set, but I don't know that.
[Android Head-Units] lucky_lucyan:
I press the reset button but it doesn't reset, it just turns off and on.

I have a Hizpo S2 with the QF03 MCU file, I was just sent this a few days ago from the amazon seller I bought from.

first post, hope this helps :)
[Android Head-Units] Philo-Men:
Hi KoTix2... For me, on a S5 QF001 (K706), it switch and work perfectly on iGO Nav. In Google Maps they are juste a delay (3sec) between the end of the nav message en the return of tha radio sound. Otherwise, the balance between the annoncements from GPS Navi and Tuner radio are wery good. Thank you for your good job (y)
[Android Head-Units] lone_slayer:
What's the difference between a QF001 and a QF003?
[Android Head-Units] KoTiX2:
Thx for your video and test.

Which app have you set as default navi app?
[Android Head-Units] MauriBixio:
1) Write your posts in smaller font sizes.

2) the physical reset button basically just restarts the HU, doesn't delete anything, and behaves like yours, everything is normal like this.

3) code 225588 only deletes user data.

4) code 22558800 "should" delete everything, so writes the seller Hizpo ... but I've never needed to use it, so I'm not sure about this.

5) have you tried to update the firmware, first enabling the "erase all user data" option there?

Maybe you have corrupted Android OS, and doing so maybe it fixes...
[Android Head-Units] MauriBixio:
Different PCB\hardware.

We still know little about QF03...but you can't use MCU file QF03 on native HU with QF01, and vice versa.
[Android Head-Units] Philo-Men:
iGO NextGen
[Android Head-Units] KoTiX2:
Ok i believe there is still some problem if you set it as default navi app
[Android Head-Units] MauriBixio:
Igo Nextgen has no problem with this HU... sure.

I use it too...best Navi app offline.
[Android Head-Units] Philo-Men:
No, it's just that it's an optimized system for my motorhome but especially offline.
[Android Head-Units] marioti:

But can we use a system firmware from all other S series on qf003?
[Android Head-Units] MauriBixio:
Yes,firmware file are the same,at least until the latest current nobody (with native QF03) has not written that had problems installing QF01 firmware.

ONLY MCU file is NOT interchangeable.

[Android Head-Units] MauriBixio:
Post #1

- how to change the boot logo:

1. If your player is 1280*720 screen, you need to rotate the picture 90 degree, and cut it into 720*1280 size, transform the picture to .BMP format.

2. If your player is 1024*600 screen, you need to cut the picture to 1024*600 size, transform the picture to .BMP format.

3. copy the picture into your Udisk root path, and then connect Udisk to the player. follow the steps settings-factory-8888-Logo set-then you can see your picture and select it- click update logo.

bmp in 24bit.
[Android Head-Units] lucky_lucyan:
that's exactly what I did

how do i root path to udisk?
[Android Head-Units] PlzzaHut:
my HU(S4) come with native QF03 and HIzipo gave me the QF01 firmware. Then I used code 774411 to flash the QF01 version

Ok so I'm still having the following issues with Android Auto:

Wireless connection for Android Auto won't work with AA version 9.7. Rolling back to version 9.4 allows wireless AA to work.

Android Auto still won't go to dark mode with the headlights, regardless of Dev Mode setting (car or phone controlled), and regardless of version.

Anyone else having these issues ?
[Android Head-Units] Steezy.:
Yes, make sure your interior dome lights are almost at full brightness. Low brightness of the interior lights doesn't seem to kick on the dimming/button LEDS
[Android Head-Units] MauriBixio:
If you have done this (and everything is correct) you must see your logo in the appropriate section of the HU in order to change.

DO NOT change the logo by selecting it from filemanager.
[Android Head-Units] MauriBixio:
We have already said that FIRMWARE file does not change between QF01 and QF03.

While INSTEAD we can't change MCU files the same way. At least...with the information we have so far, better not to.

RDS: depends on the HU radio chip on board, with native Sx HU QF01 and TDA7708 chip works.
[Android Head-Units] lucky_lucyan:
I did all the steps but when I go to update logo nothing happens.

logo are .BMP, I copied to usb, I connected to HU, I went to settings-factory-8888-logo and nothing.

only if I go into the file manager does it see them, but when I go to update logo it doesn't.

I saw that you have to a rooted usb, but how do you have to root it to be able to change the logo?

thanks!

I've managed to make an overlay app to replace some of the text and images in the original "CarAPP" in hopes to fix the broken English that has been annoying me for a while.

I'll dig into it more later and do a small write up if anyone is interested.
[Android Head-Units] MauriBixio:
Format your USB pen drive with PC, in FAT32.

Copy your .bmp logo (24bit format) internally (in the main root of the USB pen, NOT in a folder), start the HU and update the logo, from the appropriate section, as I already explained...
[Android Head-Units] MauriBixio:
It should work...if it doesn't, you have NOT created your logo file correctly.

Edit:

upload your image of logo and I'll see (as soon as I have time) to create it for you.

[Android Head-Units] Clyde72:

[Android Head-Units] xdsbx:

[Android Head-Units] Clyde72:
I think it must be that plug, the single blue cable is for an fm booster or amp I guess, constant 12V DC delivered only when unit is powered on. The blue black is possibly regulated power but I should check with an multimeter.
[Android Head-Units] lefterisa3:
But both blues are jumpered together just above the plug...
[Android Head-Units] Clyde72:
Yup but one has a return to the unit through the black wire and that makes me wondering if it would be able to carry variable voltage as part of a little circuit
[Android Head-Units] popamor:
As for boot animation, I followed this video by Erik, to create a custom boot animation to my liking. Well, I still want to soften the transition but here is the animation that I have created.

Things to note:

1. Using a lower resolution makes for a smaller total size and speedy animation

2. The desc.txt file, I did mine like so. Using p on the last line allows the unit to just jump into main screen when it is ready without needing to finish the 3 seconds (75 frames) I have specified for part1

1280 720 25

c 1 0 part0

p 75 0 part1

I put bootanimation.zip file in a fat32 USB in folder QF\auto, plug that in before booting, the system booted up, read the USB, updated automatically and rebooted into the new boot animation.

[Android Head-Units] popamor:
Can you put your comments or questions in English?
[Android Head-Units] nyp42:
I contacted the vendor for update files and they asked me to send the system information. I took a photo of the wrong screen before I flashed the first update so I don't know what to tell them. I would also like to tell them the correct info for my unit incase there is actually some difference in update files between S4 and S2 or even between the ones with 1024x600 screen and the other style with a larger screen. IIRC my original files were from July or August.
[Android Head-Units] nyp42:
Isn't this the switched power for an amplifier? There is an option in "Factory" called "Power amplifier control switch" and it is off by default. I tried it on my unit but it didn't work. Apparently fan control only works for some hardware versions though. The other pigtail would be for if you actually want to use remote power on for an amp.

Hi, make a quick test, next days I look better. ;)

With PC:

1) for ITA translation:

"default-resources\res\values-lt" folder located in "resources\res\values" folder together with your existing "resources\res\values" folder.

Edited "strings.xml" in the ITA folder above.

Once this is done, run "compile.bat".

It processes each entry, but I get a lot of "Warning...." messages. Am I doing something wrong?

Ok instead if I want to edit images, step as you explain... compile.bat re-pack the apk correctly, with desired images edited inside.

2) "Install.bat"

To use this, you need wireless adb with our HU, right?

Do you explain STEP BY STEP how to act?

3) OT.

I want to uninstall the stock app "TPMS" from the HU, as I use another app for that.

However, the stock app interacts in the background with my TPMS app, and gives me an error at every cold start of the HU.

It is NOT possible to uninstall the "TPMS" stock app with the "standard" mode of Android...with adb can it be done?

As? (right string to run with adb....).

Thank you
[Android Head-Units] patsh:
Hey, feel free to send me your edited files as well as the exact errors you get. I'll try to see can I figure it out.

I explained more about the wireless adb on the GitHub around a hour ago. Check that and feel free to ask if you need better guidance.

I'm not sure about TPMS, perhaps check out this guide: https://www.xda-developers.com/disable-system-app-bloatware-android/

I heard about this, but I've never attempted it myself.
[Android Head-Units] patsh:
I've got a question for you guys with custom launchers, did you manage to set them as the default launcher?

I tried setting both Car Launcher Free, Agama Car Launcher and Vivid Launcher as default, but it just didn't work.

Another totally weird issue I have is that whenever there's a different launcher open, there's a quite static noise playing on the speakers. It seems to stop after a while, or when playing a song. Anyone has an idea what's up with that?
[Android Head-Units] MauriBixio:
In the next few days (when I have time...) I'll try to translate.

Note:

ITA translations are bad, there are many entries to translate better!

Then I'll send you the translated ITA file if you want to test.

Thanks for the advice, I'll look at your new guide for adb...and link for unistall stock app.

See you again.
[Android Head-Units] MauriBixio:
Unfortunately I haven't tried live in the HU Car Launcher yet (but I have the PRO one, paid) but only on phone to test various themes.

However, someone uses these external launchers, it would be interesting (also for me in the future) to know how to set the desired external launcher forever (it should be easy to do this, e.g. via Car Launcher Pro setup, but from what I write to you it seems not).

Are you talking about the free version of Car Launcher...maybe it depends on this, is it possible to do everything only with the Pro version?

Which player do you use with Car Launcher?

Try "Musicolet" in Google play store, great player, fully supported by Car Launcher app.

Please write if and how you solve the problems you complain about with "external" Launchers... ;)

You just can't do what you want with these HU, firmware and mcu are "custom" for the unit, it's not full Android OS. With every other rom after that nothing will work anymore.
[Android Head-Units] MauriBixio:
blue_one said:

If anyone is interested: I've found several indicates that only a maximum of 6 GB ram can be used by the firmware. Even if the device has 8 GB ram like mine. There is also a special power profile that detects benchmark apps and only allocate to them the full power. Otherwise the system resources are distributed more defensive. Overall there is a lot of fake in the firmware.

Also the whole firmware is a security nightmare. In fact it is a debug release which never should be used by costumers. So you should not use this device for security relevant tasks. It's an open barndoor for malware.

For me I'm ok with that. I've won the dispute on Ali because of the faked android version and got 2/3 refunded. But i think at the normal costs I would go for a FYT device now.

Oh i knew they were faking the android 12 before i bought the HU. I'm quite happy with the product but if i can get 2/3 of my money back because they use false advertising & keep saying it really is android 12, that's a win for me. Would make it a €60 HU. I would buy again for that price.
