Perhaps you use CarLetter? I tried this app, it's terrible! When it starts to connect to the phone via bluetooth, it turns off access to the Internet and you need to turn on the Internet every time after reconnecting. Auto connection to the network, etc. does not work with this application. Plus, many applications hang when CarLetter is running. In general, I deleted this application from the phone, and turned it off in the radio tape recorder and all problems disappeared!
[Android Head-Units] ali_abbass85:
I am having the same exact thing, I am forcing reboot before driving and make sure there is 4G..
[Android Head-Units] Aaantonn:
I turned off the program I was talking about, uploaded the update and everything works without glitches.
[Android Head-Units] jagd71:
And how did you remove the carletter app? I don't have the uninstall option...
[Android Head-Units] jagd71:
Or how did you turn it off?

Hi , i recived a firmware and mcu update fom ossuret for my S7

The system firmware link：

https://jitufirmwarecarletter230207.oss-eu-central-1.aliyuncs.com/update.zip

The MCU document link

https://jitu321077708mcu230207.oss-cn-hangzhou.aliyuncs.com/mcu.bin
[Android Head-Units] Aaantonn:
Have you tried the new update? What has changed or been added?
[Android Head-Units] KLJ617:
Mine let me update the system, but not the MCU. Any suggestions?
[Android Head-Units] Aaantonn:
MCU does not need to be updated if all your hardware is working correctly! If you want to update the MCU, ask your seller for it, since only he knows your device, the one that was sent to someone else may not suit you. Installing the wrong MCU will cause serious problems and you may not be able to do anything without a specialist! Just read about the MCU on Google.

The seller sent me the MCU, because the system did not work correctly, especially the amplifier.
[Android Head-Units] Clyde72:
You can not update the mcu for your S4 with one for S5-S8, that is why it didn't work.
[Android Head-Units] KLJ617:
Thank you both
[Android Head-Units] jagd71:
Any changelog info?
[Android Head-Units] J series:
Does anyone have QF003 mcu file ??????
[Android Head-Units] J series:
I tried entering the code, and it said it was updating, but nothing happened
[Android Head-Units] bastikf:
Hallo, ja, ich habe einen QF003-MCU, aber nur auf meinem Steuergerät.

Nun, heute habe ich versucht, den Original-MCU q0f001 zu installieren, aber es ist unmöglich, sagte das Steuergerät, es ist nicht der richtige MCU.

Gestern habe ich meinem Verkäufer geschrieben, wenn ich das Gerät zurücksenden muss, bekomme ich keine Probleme mit diesem MCU (Garantie). _F..k,

i have an 3er version and i cant change it back to the q0f001, great weekend!
[Android Head-Units] ImBenny:
Update:

I deleted and reinstalled Android Auto app on my phone and the Wireless AA worked only once on the first run.

After that I reverted back the version from 9.5 to 9.4 and I got it work again more than once till it started the fail again randomly.

I am 100% sure about that the fault is caused by the phone.

Maybe the Carletter app version is too old for the latest AA. But it says it is up to date.

I haven't tried the Zlink yet because it is Unactivated to me.
[Android Head-Units] MauriBixio:
EN... please.
[Android Head-Units] PlzzaHut:
As I post before I downgrade the QF03 to QF01, and nothing happened, everything looks ok. just use code 774411 before flashing.

But does anybody have the QF03 firmware for S4? I want to compare them.
[Android Head-Units] bastikf:
sorry. yesterday i tryed to downgrade but it doesnt work, the radio says: these mcu doesnt ready for thes headunit. Today my seller wrote me, i can send the unit back.
[Android Head-Units] one_goldern_heart:
I have MF03, I tried dump with code 45645600 and it says saving mcu; but when I look into my usb/ustick it shows nothing. any ideas where it saves after dump
[Android Head-Units] MauriBixio:
Maybe internal storage\download folder?
[Android Head-Units] J series:
That’s the first thing I try I even download it ES file explorer to no avail
[Android Head-Units] air32:
I can confirm that, only after i downgraded aa to 9.4 aa wireless works again. The app tells me to update asap, otherwise soon i cannot use aa with the older version.

Any suggestions what could solve the issue ?
[Android Head-Units] marioti:
Are you try to make an update AA, on both devices, mean your phone and the HU?
[Android Head-Units] one_goldern_heart:
Is someone still looking for QF003 mcu file
[Android Head-Units] air32:
No cause i thought carletter is the corresponding part on the hu side, didnt even know If aa is installed there
[Android Head-Units] Barykelo:
I will try even without control CheckSum.
[Android Head-Units] halloj:
I updated successfully. In your case turn off checksum test. Graphics is totally different. Not launcher, but the rest. S8 2023.06.14.103953_2.56_01
[Android Head-Units] Gyovany96:
Let us know after that.

Also your HU model and if you notice something new.
[Android Head-Units] Gyovany96:
What's your HU model?

Also what so you mena by graphics? Update progress graphics?

You noticed anything new so far?
[Android Head-Units] halloj:
Read #397
[Android Head-Units] MauriBixio:
And your MCU QF01 or QF03?
[Android Head-Units] tlf55:
Graphic is different in a good way or bad way ?
[Android Head-Units] halloj:
QF01 1.73
[Android Head-Units] halloj:
Good, in my opinion. Carletter still only in wired AA.
[Android Head-Units] Gyovany96:
That doesn't seems right. This white "theme" happens on old FW too, but reboot solves it. Try rebooting the HU
[Android Head-Units] halloj:
Why, I don't have a problem with that?
[Android Head-Units] Gyovany96:
Because all your colors are inversed in every app. But if you like it that way, no comments! :D
[Android Head-Units] marioti:
After instal a new soft, you can just change the launcher theme.

New thing i notice is a customisable automatic dark/light mode with backlight strenght. You can choose between setting a dark mode with a car lights, or it'll be set in time period (eg. light mode between 7am to 7pm),
[Android Head-Units] marioti:
the seccond screen. where do you have it? I haven't found that
[Android Head-Units] halloj:
Touching the cogwheel in the left lower corner of the launcher.
[Android Head-Units] Gyovany96:
Did you skipped CheckSum check or just don't have the error?
[Android Head-Units] marioti:
I have there old version of setting menu but just in light mode. hmm..
[Android Head-Units] marioti:
i download it twice using different browsers. and also use two different pendrives. No matter this i also got checksum error, so just disabled to check it. So far all is stable, have to test more
[Android Head-Units] halloj:
Can't help you with that one. Just installed it and didn't touch anything. Came out as on the pic above. I did clear the memory if that matters during install.
[Android Head-Units] halloj:
Well, it's easier than rebooting. Just pull down the top bar, there you can select between dark or light theme. I still prefer the light theme.
[Android Head-Units] MauriBixio:
Also I have never seen those icons\menu like in picture 2...current firmware 0414.
[Android Head-Units] Gyovany96:
Yep, just updated too. On previous firmware that white "theme" was a bug that actually inverted colors. Now they added Light/Dark themes, although seems like not all launcher styles have a light theme.
[Android Head-Units] MauriBixio:
So those icons\menu of picture #2 are part of an update of an existing launcher even before this new firmware (I never saw them until 0414...) or are they of a new integrated launcher now?
[Android Head-Units] Gyovany96:
I never saw them either.. Didn't test entering settings from all launcher styles tho, but it could be possible to be a part of an Light theme compatible Launcher. Unfortunately I'm not at the car to test this theory..
[Android Head-Units] itiswitis:
Just saw the same screens on a Aliexpress listing for a Hizpo: "for our S series items can change its User Interface as"Day & Night" mode.more details can check as follow first picture show.."
[Android Head-Units] MauriBixio:
And info about the choice of using day or night theme?
[Android Head-Units] halloj:
Already discussed here how to: #416 Also possible in settings to select fixed time or automatic selecting dark mode/light theme.
[Android Head-Units] marioti:
can anyone write to vendor and ask about new soft. Yes i know there is one on autofather but it have checksum error.

My seller Osuret give me a 0424 as the newest ;)

IMO it's qute possible to get a changelog also from Hizpo (just like before)
[Android Head-Units] MauriBixio:
In summary (right this?):

here is the latest firmware

https://jitu2firmwarezlink20230614.oss-eu-central-1.aliyuncs.com/update.zip released few posts back in this thread,

but it creates checksum error when you try to install it (by-pass this by disabling the option) but still we don't have all the logo of the changes in this firmware, we only know that they added day\night theme, with possibility to manage these themes too with pre-set time slot or with car lights, right all this?

I had downloaded from this link when it was presented here days ago and no virus alerts or similar, but I have NOT installed it on the radio yet.

While from "https://autofather.com/s_sjjc" the currently present firmware creates download alerts and is it corrupt?:

https://jitu2firmwarezlink20230614.oss-eu-central-1.aliyuncs.com/update.zip

I try again to write to Hizpo... I already asked them 3 days ago for the new firmware but they say it's not available yet, but maybe they're being "smart"...
[Android Head-Units] one_goldern_heart:
I got the same link from Hizpo for 20230614 and tried but got checksum failed. is it safe to bypass checksum when updating firmware?
[Android Head-Units] mfgrellen:
I installed the new software some days ago. Till now i cant see any faults and the new Day and Night Theme is fine. Also checksum error, but i think its ok!
[Android Head-Units] mariodantas:
Same here, all ok !

But thank you :)

I constantly read the forum, I know everything, my post on Hizpo links was just to make further confirmation that the latest current firmware is the right one, but anyway, another time, when I get a new firmware, I'll keep it for myself since which seems to have done "damage" to publish the links ...
[Android Head-Units] werhere:
here is hizpo/QF firmware engineer, if you have any suggestions for our product, we are great to have your message.
[Android Head-Units] Clandaries:
Yes. Make the steering wheel buttons (for telephone) work with Suzuki without canbus please. All other head units are working :)

Thank you.
[Android Head-Units] janolelapin:
I did the update now.

Car radio is more stable

To select some settings (The language) I used a mouth. Aspect screen is quite well.

The radio works better.
[Android Head-Units] werhere:
the steering wheel control without canbus need to connect KEY1 and KEY2, then you need to study in the KeyStudy APK
[Android Head-Units] Clandaries:
They are connected via harness. So no. Music keys are working but the headunit does not recognize the telephone keys.

Suzuki Swift Sport NZ (ZC32S) from 2015
[Android Head-Units] marioti:
have some first suggestions, just for software

1. Radio app is 1 level volume lower as the rest. is there a way to give this app a volume control or level up the volume. Because of that, when radio works with any app (like google maps), the navigation messages are much louder as the radio it self. This volume level i can see also in audio menu on instrument cluster. If i set a general volume to level 3 (on unit) same time my instrumetns show level 2 - i can make some video abotu, if you want.

2. the DSP dont have any possible to save my profile. So, you can spend a lot of time to set equalizer, and then, just by accident, press the "default" button and you loose all your settnigs without no possible to retrieve.

3. In car (like my) if you have separate (oem - from factory) amplifier, the volume is setting very high. So in "factory" menu i have to decrese volume to max -15db, but even that, you can still here a noise from speakers (without no sound is playing at the time)

4. The automatic translation is bad for me (i'm from Poland). Maybe there is some way to fix that. I can help if i will have acces to a good english translation.
[Android Head-Units] tlf55:
Also I find that in CarPlay the contrast is too much saturated which make google maps too white and can’t see the road streets.. I tried the VCOM in display settings in factory 8888 but that doesn’t change anything ..
[Android Head-Units] itiswitis:
Good to have you here.. a few suggestions for future updates:

1. Allow disable of internal microphone (via software options).

2. Allow internal/external microphone gain control (adjust mic sensitivity).

3. Bluetooth OBDII adapter does not connect to Torque (or any OBD app) when phone is also connect via Bluetooth. Workaround is to disable bluetooth on phone, load Torque to connect bluetooth OBDII adapter, then enable bluetooth on phone.

4. Save/export/import DSP profiles. This has be recreated after every update.

5. Volume level 1 is too loud.
[Android Head-Units] MauriBixio:
Today I updated my S8 firmware with 0614.

Everything seems ok (really short test, next days I'll see what happens better) except this:

It won't load my phone book via BT into the radio.

With all previous firmware everything was always ok...

Anyone else encounter this problem using this new version?

And (for those who have BMW car) and canbus LZ problem:

The controls on the radio for managing the AC climate control do not work.

It would be very useful to solve this, as the oem air conditioning unit is partially hidden by the radio installed in the dashboard, and you see almost nothing on the oem display where you normally set the temperature.

Being able to do it instead via the radio would be VERY convenient!

-------------

EDIT:

Phone book problem fixed:

-The pairing with the radio has been removed from the phone.

- Search and pairing of the radio redone, enabled all the options of the BT profile in the phone (including phonebook sharing) and now everything is ok.
[Android Head-Units] halloj:
Phonebook works for me. Have you activated download of the phonebook in your Bluetooth profile in your phone?
[Android Head-Units] MauriBixio:
Yes,

everything is like before i did update new firmware, i didn't change anything in the phone BT settings.

With 0414 it was ok to upload address book, after it seems no... but I will also do other checks, thanks for your answer. ;)
[Android Head-Units] halloj:
In that case I would erase my HU profile in the phone and try again.

the setting svae after update like dsp we will discuss about it.

volume 1 too loud we have solved it, please tell youe mcu version.

Please look also on my suggestions here #440
[Android Head-Units] itiswitis:
Thanks. Understand on mic circuit. option to increase mic sensitivity would be good, if possible. I see we can disconnect pin1 and pin2 on a ribbon cable to disable internal mic, but I would like to avoid internal physical modifications.

Looking forward to new updates.

I'm running MCU version 20230207, and software 20230614. I updated to 20230614 yesterday. Is there a newer MCU version?

1. it will be helpful if you can upload a video and send me the link.

2. we are considering it on our futher firmware

3. if it is electric current sound, you can add a Ground Loop Isolator on the AUDIO out to fix it.

4. please leave me you email address, i will send the document to you and please help us to optimize the Polish translation.

thank you so much
[Android Head-Units] tlf55:
Yes but it’s actually not a solution.

I mean I want my map to be white in day time so I can see better when direct sunlight is on the unit . I had an other unit before this one with the same issue but the VCOM in display setting was the good solution.. here it just does nothing.

So you must update so the VCOM does actually something or just make the display color more accurate via firmware update so we can use CarPlay in light mode if we want to use it that way

Jeeez these auto translations really stink.

Dsp has a setting for "STEN" which litterally translates to a rock. Not the music genre, but a standard grey rock found on the ground.

As for AA wireless and carletter, the wireless enable is on the phone, not the HU. Worked flawlessly w carletter for me for past 5 months (if you discount the xiaomi power save bug).
[Android Head-Units] ribasman:
I've some suggestions to make since a few months when i bought the Hizpo S7 unit.

1- I believe lots of cars has console buttons that opens certains apps like navigation. So the ability to choose a downloaded instead of a stock app for some functions like radio, media, bluetooth caller etc will be much appreciated when we press one of those buttons

2- I also believe that may cars has some sort of joystick at the console buttons. Mine has but all it can do is to switch between songs or radio stations when rotate but could be used as a mouse pointer as well using the left/right/up/downs buttons aind off course enter. I think this should be at ECU decoder level.

3- Why not head unit send some information to the ECU like radio or song being played? that piece of information could be shown at driver's screen and now is a misread screen.

4- Air conditioning popup it's great. But when i make some change cames with two big errors. Adds 2 celcius degrees to the real chosen temperature and misplaces left/right at least in my car which has dual zone.

5- Why not for those people that connects a SIM card for mobile data and enjoy a big security advantage when our car is stolen for ex. Since the unit turns on will keep on sending gps location for a server like SinoTracking (there is more) every minute or so. There are apps for this but problem is that i can't make it work unless i manualy start it which no burgler as intention of doing it. Even better that runs completely invisible.

6- Improve by a lot the caller by bluetooth app. It's horrible. it's super dated.. I can not ask to google assistant to make a call to anyone since the unit has no service installed. But i can ask google assistant to set a navigation route to anywhere which is great and runs smooth.

Thanks

Hello, please give option to increase number of simultaneously connected bluetooth devices (atleast 3 concurrent connected devices, OBD-reader, phone, and one additional)

Please give option to set default audio stream (bluetooth, android auto, fm, mp3)

Please give option to set amplifier chip passthrough ie "car has amplifier that demands differential signaling, and -15dB is nowhere near enough"

Please give option to disable audio beeps for voice commands (insane volume level, speakers almost explode)

Please give option to have torquepro widget in all launchers without the DVR-setting workaround

Please give option to remove unused widgets from launchers

Requests for new future firmware

Current frmw: 20230614

MCU: 230207

Premise

With BMW cars the Canbus functions are limited:

1) real BIG problem to be solved, the AC climatic control management DOES NOT work with the unit.

With my car this is a BIG problem, since my unit (S8 8G\128G) when installed on the dashboard with a special frame, covers the display under it of the oem display of the dual zone AC climate control panel, and afterwards it is VERY difficult to These physical commands show the set temperature on that OEM display.

So being able to use the unit to set the AC temperature instead would be CRITICAL that it worked on the unit. Please consider this, which anyone with BMW cars requires.

In my picture you can see the current info my sw canbus\car.

2) No canbus info of car fuel data, average fuel remaining. etc, neither on the unit nor on the oem dashboard display of the car.

3)I use Toppal AI Standard version (regularly purchased):

Because if I set the "Toppal Voice" voice app when I press the PHYSICAL button on the steering wheel enabled to manage voice commands, it does not WAKE UP Toppal AI to accept a voice command, but instead opens the Toppal AI app setup screen ?

Please consider fixing this "bug"...Toppal is very useful, but waking him up ONLY with your voice or with a floating icon on the monitor is not very convenient compared to ALSO having the waking function with a physical button on the steering wheel.

Thank you
