Look at the link with firmware. You'll see there "..zlink..." in its name. Last 3-4 firmware updates create zlink as a main app to AA. But it can be change. Go to Settings > Factory > 8888 > and on one of the position (i think last on the list) you see zlink possible to change to carletter. After this, reboot the HU, and enjoy Carletter
[Android Head-Units] air32:
Thx for reply, i used carletter since the beginning but one of the last AA update crashed the function. Some guy named a explicit version (9.7.632204) which should work, i will try again with that version. Some other said the version of the HU und Smartphone has to be the same but this makes no sense for me cause AA connection is established on the phone.

Anyway if it doesnt work i will update my hu to newest firmware and try zlink. Both apps are installed and licensed on the latest firmware?
[Android Head-Units] MauriBixio:
Zlink will probably not be activated.

The seller (if he wants) can do it, providing him with an image of the Zlink app QR code, but he is not obliged, since CarLetter is the native app activated.
[Android Head-Units] halloj:
I asked the seller for activation of the Zlink, but they said no. I even offered to pay for it, but still no.
[Android Head-Units] balkanera:
Did you after update make a internet connection for zlink to activate ?? On iPhone I Need to forget bluetooth from radio in iPhone Bluetooth settings and search and couple new then it works.
[Android Head-Units] MauriBixio:
Zlink activated or not it's an old story...some people have it activated...but many don't,regardless of how you act for BT on\off etc.

And after without activation code it doesn't work.

I am yet to purchase this stereo but am likely to do it in the next few days (waiting on car to arrive)

I have read that this is not android 12 but android 10.

Any chance a future upgrade can display the correct android version?

In the future are we likely to get higher android numbers 11,12 etc?

Also is there a timeline for fota updates?

Thankyou for coming to this forum, it's great that you are actively seeking ways to make this a great product.

Hi, I'm the developer of the NavRadio+ app and i found some issues on the radio FM:

1. On models with radio chip TSC4745 the RDS text is not shown at all while the models with radio chip TDA7708 it work perfectly.

Is this a limitation of TSC4745?

It can show correctly the RDS PS (station name) so this chip can handle the RDS without problem.

Could it be an MCU bug instead?

2. Either with both radio chip the PTY information show always "none" because the received code is always "00"

3. I have a small request for better handling the FM radio: is it possible to add the reception of the RDS PI (pi-code) of the radio station into the radioFM app?

I can handle already all the RDS Infos sent by MCU but I'm really missing the pi-code to make some automatic features that already work on other brands like MTC.

Thx for you reply :)

A lot of useful information is concentrated in post #1 of this thread, including what you ask about the Android OS version of these units, etc.

[Android Head-Units] zerebede:
Hi There

I was the one who told about version 9.7, what is certain is that it worked fine until the radio completely shut down. after that the AA only turns on after a few minutes after getting into the car. I think that the problem does not lie in the carletter but in the AA, since this started to happen after the AA went from 9.4 to 9.5, that is, the carletter turns on the hotspot immediately but then the bluetooth connection signal takes time to reach the carletter. The official AA 9.7.632214 came out yesterday, which I already tested via apkmirror a week ago and everything was still the same. Try to get in the car, open the carletter and you will see that the bluetooth signal is not green, if you have the carletter in automatic mode you will see that after a few minutes the bluetooth will appear and the connection will be established. For me this is a problem caused by the AA, but now downgrading the AA to 9.4 it is no longer possible to open the AA if you don´t update it. As long as it was possible I used AA 9.4 without problems.
[Android Head-Units] Barykelo:
you cannot use MCU QF01. You have QF03. There is no new MCU for your hardware yet.
[Android Head-Units] zerebede:
It happened after Android Auto updates. try to put Careletter on auto mode, open it and wait until de bluetooth signal get green on careletter. after that it will connect itself. This is after android V9.4

Edit: I`m in contact with HIZPO guys to know for a Z-Link solution.

Hello. I'm new to the forum. And I can't figure out which theme is for my android multimedia. I own a Ford Mondeo MK4, and in the system information against the model it says k706. I have a problem with the default launcher set. Can you help me ?
[Android Head-Units] MauriBixio:
Probably if your HU is native "all QF03" (frm and mcu),updating frm with QF01,after, doesn't allow update of MCU file.

We don't know QF03 well yet...so let's assume.
[Android Head-Units] MauriBixio:
Sx model?

Native firmware and MCU is QF01?

ONLY if native MCU is QF01,last file available:

[Android Head-Units] lucky_lucyan:
it seems that all S8 versions that have software QF001 and MCU QF03 have a lot of errors.

I've also seen others, I can't change the logo, the codes don't work, the FM radio and the sound don't work, Wi-Fi and many settings don't work.

for those who want to buy, be careful not to use this software
[Android Head-Units] MauriBixio:
But... when this unit arrived did it have all these problems you write about or did they arise AFTER you "worked" on it?

If in the first case,send the unit back to the seller, in the second... you made a mistake in acting,in some way.
[Android Head-Units] lucky_lucyan:
when navi arrived, I couldn't change the logo, the codes didn't work, the radio only picked up a few stations and the wi-fi disconnected from time to time.

that's why I wanted to give it a total reset but I didn't succeed because the codes don't work.

I installed the QF001 software and it seemed that I had solved the problems, but I still couldn't change the logo and the codes didn't work either, but the radio, sound and wi-fi worked.

I installed the MCU QF03 and the radio and sound don't work
[Android Head-Units] fefferico:
Hello, I can confirm this. I was able to make it work somehow via Bluetooth but asap I restart the engine the green icon was gone and the only way to connect the smartphone to my car was via USB cable. I installed 9.7.632214 version in the smartphone (632204 does not exist if I recall it correctly) whereas I don't remember car version.

Another thing that I noticed with latest firmware is that if the smartphone is connected and Audi shared, you have to be inside the "Bluetooth audio" app to actually be able to listen to it. Previously whatsapp voice messages, for example, were audible as if the car was just a speaker for the phone, while now I have to open that said app.
[Android Head-Units] zerebede:
Here it is. I'll try AA 9.9 beta today. PEACE

Edit: AA 9.9 sucks 😡
[Android Head-Units] MauriBixio:
So:

did you have native frm and MCU QF03,in which you couldn't change the logo...but EVERYTHING else worked?

Later, you changed frm, installing the latest version of June QF01, but the logo didn't change (only that? And did the rest work?)

After that, you tried to update MCU QF03 (which you found WHERE?)

DID YOU CHECK BEFORE THAT THIS WAS SUITABLE FOR YOUR HU, I.E. IT MATCHED FOR DSP AND TDA RADIO CHIPS?

This is crucial to know, BEFORE upgrading MCU!

If the current QF03 MCU file was NOT right for your HU, of course nothing works now...you had to check BEFORE you act...try asking your HU vendor if they provide you with the right QF03 MCU file for downgrade ,but if he finds out that you made a mistake and did damage...the HU warranty is lost,and you can't even return it (I think).
[Android Head-Units] lucky_lucyan:
I said above all problems before software installation, not just logo change

I wrote to those who sold the unit to give me the correct MCU​
[Android Head-Units] air32:
Hey, thx for your comment.

Yes there are exactly my experiences with the issue.

I tried different versions of AA and even with the 9.4 release it only worked one time and after that the connection takes a few minutes. When you clean the app data it connects immediately but this is no real workaround cause everytime to clean and reconfigure AA is no option or me.

But the issue has nothing to do with the AA version on the HU they are not corresponding, AA is not even needed as installed app on the HU.

Anyway, im not sure if updating the HU to the newest firmware/mcu fixes this problem...i think i will try but im afraid it will be the same. ZLink seems also no option as i read it cannot/will not be licensed.
[Android Head-Units] MauriBixio:
You have gone through the correct step now.

Don't tell the seller that you have updated the firmware with QF01, better if they also send you the QF03 stock frm of your HU.

Reason: if doesn't solve your problems, downgrade frm and mcu stock QF03, and send the HU back to the seller, asking for a new 100% working HU!
[Android Head-Units] lucky_lucyan:
I solved it, I managed to write the software MCU QF01 over MCU QF03

with code 774411 you can write any software
[Android Head-Units] halloj:
I solved the problem with Carletter vs. Zlink. I bought this one. It has Zlink & MCU QF03 & QF001 FW.

[Android Head-Units] MauriBixio:
I understood this!

My advice to have both stock frm and mcu QF03 for your HU is ONLY if unfortunately you can't fix everything and you have to send the "defective" HU back to the seller...
[Android Head-Units] lucky_lucyan:
they sent me the QF001 software and the MCU QF01 software, they said it was a mistake on their part.

they said to ask the specialists to see what the problem is.

only the problem with the logo remained, but it's fine even that way.
[Android Head-Units] MauriBixio:
Logo:

can you enter the logo change screen, but after that you can't load your .bmp file to update it?

Do you have a mistake when you do this or what exactly happens?

If you want to try (just for testing) upload my attached file for the logo, if it works, tell me the brand of your car and when I have time I'll draw you a similar, suitable one...

Unpack and put the .bmp in the root of USB stick,formatted in FAT32.
[Android Head-Units] lucky_lucyan:
only the problem with the logo remained, but it's fine even that way​

I see what I have and what you sent, but it is not set as the startup logo
[Android Head-Units] MauriBixio:
Logo:

can you enter the logo change screen, but after that you can't load your .bmp file to update it?

Edit:

I want to clarify that we are talking about changing the logo at startup of HU to COLD, and NO of the Android animated logo that appears after this ...
[Android Head-Units] lucky_lucyan:
yes, I am talking about the fact that the logo does not appear at all

but now I will install the new software plus the MCU software and then try again

Hi Everyone, I've just bought this Android car head unit: https://es.aliexpress.com/item/1005...st_main.4.7467194dh9t2NR&gatewayAdapt=glo2esp

Specifications:

- Chipset: 7862/TS10/T5

-Cores: 8

-Memory: 8GB

-Rom: 128GB

-Android: 12 (probably fake)

It is my understanding out of these specs, that it is an s5.

Issue

I've updated the system, from system options, but it stayed in a permanent boot loop. I'm not able to retrieve any more system information as MCU

Out from this thread, I found the following firmware: HIZPO_S5-20230627T180051Z-001.zip (https://xdaforums.com/t/firmware-qf...62a-7862s-not-fyt-based.4541261/post-87994043). Do you think it might work?
[Android Head-Units] itiswitis:
There several brands of these units, but your unit seems to be have some variations from the S-series units made by Jitu tech. S5 has different specs. Did you get a picture of the stock system info, system/mcu version before you updated?

Not sure where you found that version of the firmware, since 20230614 (or 20230615) is the newest version as of today.
[Android Head-Units] jocheinfa:
Unfortunately, I wasn't able to obtain a picture of the stock system info. If I try to update with the firmware you mention, can I brick the device? I'm also not sure if it is QF001 or QF003. But maybe I can download the firmware and try to update if the risk is low.
[Android Head-Units] lone_slayer:
My GUESS is that your unit is not for this thread I would use the search option and try TS10 I did see multiple threads for headunits with TS10

[Android Head-Units] MauriBixio:
QF01 firmware can be installed on QF01 and QF03 native units, while for MCU, QF01 native units must use QF01, QF03 native units must use QF03.

The seller is refusing to send the information about MCU if QF001 or QF003. Is it possible to see this by opening the unit and checking the board?

Maybe you can tell them that the unit worked for a few days and now it's stuck in a boot loop, which is true. Ask them what they recommend for troubleshooting/recovery. Don't say anything about your attempt at upgrading or firmware or mention QF001 or QF03.

Your unit is not a TS10, it's not a ROCO k706/QF01, it's not any of the common models around here on XDA.

You should look around for a KC97 model but I don't think you can find a firmware for this unit on XDA. Maybe you can be lucky on 4pda.ru but it would be better if you ask the firmware to your reseller.

He also mentioned, after screen goes off, the music still plays normal. He also receive a new unit from the seller but the issue was still there. He didn't get a new cable harness with new unit, so he buyed a new adapter with canbus, with no luck, until he unplug the plug with sim slot cable. Now he don't have a GSM but the HU works good

You should not have screen off but is not permanent fix. Can try. I think is MCU incorect version installed.. have buy from joom.. and no suport from seller.

I have read system_log but I'm not engineer or dev to make some conclusion.. but there's last registed error are from MCU then got screen off or white screen.

E/mcu_services ( 5420 ) is MCU error.
