I've been fighting back and forth with the seller about this for many days, but no success...they don't seem to understand what is the problem and when it comes to some solution, they just return to good-ol' "unit doesn't support this feature".

But, from what I learned so far, in order for wired carplay to work, the phone must be connected to the OTG USB port, which our units seem not to have routed out of them at all in the connector layout on the back. Maybe it would need to be soldered to the mainboard. That however by it self would not enable the connection in the Zlink app, that would need to have an update to the app, where it is enabled. I believe that any of the USB ports on the unit can be "transformed" to the OTG ones, and then the functionality enabled in the FW/app, but that would require the seller/factory to actually listen to the demand.
[Android Head-Units] Vampire_Dracula:
Isn't this an Apple limitation? I remember I tested the wired Android Auto and it worked.

However, I don't see why one would prefer the inconvenience of using a cable. Wireless AA works perfectly.
[Android Head-Units] ScorpionSX:
I don't think this is Apple limitation, there are units which support wired CP as well. And you can also get a separate USB dongle (Carlinkit for example) that will provide wired Carplay, but through a different app than Zlink, so I'm not sure how it will be integrated in the car all together (switching the songs from steering wheel, etc...).

For one thing, the wired connection is more stable as I experienced, or at least you should have the phone on charger to have more stable connection with wireless connection. On longer drives it occasionaly skipped a little in the song, or in the navigation app. I had similar experience with iPhone 12 and previously I tested it also with Android phone - Redmi Note 9 Pro. But it was a different unit, I didn't do the tests on this S5 unit that I have right now. I usually always put the phone on charger when I use Carplay, so it may be better even without charging. But I would still prefer the option to have both connections possible.

hi guys. I have a deelife bluetooth tpms but I can't get it work cause it needs bluetooth ble support. device works on phone. any chance to make it work?

edit: I found it! To activate bluetooth ble on these devices is to change bluetooth type to data on factory settings (8888) page. after that you can connect to any ble device (including bluetooth low energy obd devices).
[Android Head-Units] Vampire_Dracula:
I never experienced any problems with the wireless connection

I have a wireless fast charger in the car (actually I have 2 of them) so I don't need a charging cable. If you don't have one, get one. This one works just fine: https://a.aliexpress.com/_mrV1ArO (I ran it's USB cable through the dashboard, for a neat clutter free installation)

Before installing this new headunit, I used the AAWireless dongle with the OEM headunit and it worked fine (better than Carlinkit and Ottocast).

But this new headunit does a better job switching between Android Auto and Bluetooth voice calls and music, and it's visibly faster in establishing the initial connection.
[Android Head-Units] ScorpionSX:
I do have a Magsafe charger attached on the air vent and cable routed through it behind the dash, so it's also very seamless (although still not 100%, as I don't like the vent being blocked and I don't want to glue anything on the dash) and that's what I use now. I put the phone on it for a longer drives when I use Carplay, so it stays charged and has basically no interruptions during the Carplay connection. For a shorter drives "around the block" I don't often use Carplay, so I keep the phone in my pocket and just alter between USB drive and FM/DAB radio playback.
[Android Head-Units] Clyde72:
Thx but I asked because you never answered if it was completely dead or so... Hope it can be revived some day
[Android Head-Units] Vėžys:
I hope so too. And thanks for asking
[Android Head-Units] nyp42:
Yeah I think you are right. I tried doing the auto update install. With the unit already running I plugged in the USB and it started loading the update immediately. It seems it is the Android OS that auto loads the firmware and not the boot loader like I'd hoped.

Incidentally I actually took a normal update.zip file and renamed it update_auto.zip and put it in the correct folder. At first it didn't work but when I added the update_auto.txt with the firmware version off it went. It seems the unit autoloads any firmware if it setup correctly on the USB stick.
[Android Head-Units] ali_abbass85:
new here, recently added ROCO K706, thankfully because of this thread I was able to fix few issues, but still having few:

1- I did the firmware upgrade but still seem the FAN is always on, regardless of the temp, that is a bit annoying

2- is there a way to change the speed Km/h to Miles/h?

3- the signal, and car notifications, are very loud and annoying, I read in another thread that removing a resistor would lower it, was this tested by anyone?
[Android Head-Units] Clyde72:
Seems like it works in 2 directions, as for 1126 I didn't know what to do with the QF folder I tried manually with the zip file in root on Udisk but worked only after I changed update_auto.zip to update.zip... Did same thing with 0104 major update.
[Android Head-Units] Clyde72:
@nyp42

You didn't do anything wrong. I just tried 0103 mcu for S4 and seems it is 1216 mcu. I just cancelled...

I'm gonna wait for the next major update.

Allready pleased that AF on FM finally works with 0104 fw update. Reception is better with it.
[Android Head-Units] Clyde72:
On what version fw & mcu did it get stuck in fact? I don't remember.
[Android Head-Units] Clyde72:
1 - which connector did you use for the fan?

2 - tought it can be changed in system settings like you would for timezone, system language etc

3 - go over the whole thread, I think somebody did mention removing a resistor some days ago or search the thread
[Android Head-Units] Vėžys:
This version
[Android Head-Units] Clyde72:
Thx, 0920 on S5 thus. Maybe finding 1019 fw & mcu files would be helpful...
[Android Head-Units] Clyde72:
@Vėžys 1019 firmware found on Jitu servers https://mega.nz/folder/rBZFXaRI#Uu_gnPwraDDdSPPP8GgX9A

Worth a shot maybe, either trying manual update or auto update the way @nyp42 explained.

My HU works quite well. I saw I had to stop the RDS for the radio if no the radio stations skip by themselves. But the name of the radio stations displayed normally and don't move after.
[Android Head-Units] Vėžys:
Does not work, unfortunately
[Android Head-Units] popamor:
How is your fan connected? Looks like you have 3 wires coming from the fan.
[Android Head-Units] b0gdi:
I also have Carletter app and it has Android Auto and Apple carplay.
[Android Head-Units] popamor:
1 - I have the same issue as you. Are there folks who are seeing the fan speed differ as temp rises or decreases? @Clyde72, does your unit fan speed up and down depending on the temperature of your unit?

2 - The default launcher seems to not be able to switch to miles. Pick one of the other launchers and long press on the kph area, then you are given the option to pick miles.
[Android Head-Units] Vampire_Dracula:
I understand.

One more thing: depending on your car model, you may find dedicated brackets, able to leave your air vents free, without using any glue.

I have this one for my Honda CRV and it fits perfectly (looks like OEM).

Thank you. Can you explain the diference between TDA and TSC ? What version should I use ?
[Android Head-Units] XDC34M:
If you have TSC chip you use TSC, if TDA then TDA.

If for example you have TDA but use TSC, best case you'll have no sound, worst case you'll have an expensive brick, paperweight or doorstop

Best practice is to check the last six digits of your new MCU file and compare them to the currently installed MCU's last six digits. They should be exactly the same.
[Android Head-Units] Calin1923:
Nice :)) And how to find what I have ?

You have to check for right DSP chip number as well.

Well, it's only happened once. It restarted and it hasn't happened again. Worse is the black screen, random reboots and sudden mute, and this:

It happens quite often and it is very annoying because no matter how much you press "Close application" it does not respond, only if you press outside the dialog several times it disappears, but then it appears again and so on until it no longer appears. Does anyone know what could be the cause?

For the black screen I have already contacted Hizpo to send me the screen cable.

Dobrý den,

potřeboval bych poradit s mým Hizpo S5 4/64, konkrétně s vypadávajícím GPS. Potíž je v tom, že neumím anglicky (jsem už starší pán) a překlady jsou vetšinou dost zkomolené. Já jsem z Opavy, proto píšu Vám a také proto, že jsem při pročítání fór zjistil, že jste už dost zběhlý v problematice rádií s Androidem. Myslím si, že bych dokázal popsat svůj problém mnohem lépe v rodném jazyce.

Vložím pro jistotu text jak v češtinš, tak přeložený googlem.

S pozdravem Náhlík

Good day,

I need advice with my Hizpo S5 4/64, specifically with the GPS falling out. The problem is that I don't know English (I'm already an old man) and the translations are mostly garbled. I'm from Opava, that's why I'm writing to you, and also because, while reading the forums, I discovered that you're already quite proficient in the matter of radios with Android. I think I could describe my problem much better in my native language.

To be sure, I will insert the text in both Czech and Google translated.

Hello everyone. I have been following this thread for a while but couldn't find anyone with the same issue that I have with my S8 unit installed in a VW T5.1, current sw QF001.20230824.202940_v2.69_02, MCU QF03.V01.05.20230617.002121. With every cold boot the unit just gets stuck at the "powered by Android" logo and doesn't start; to get it running usually I have to power cycle 4 times and keep trying to touch it with 5 fingers repeatedly, then the blue Android logo appears and the unit starts. I currently have 1 day sleep time set, during which it works as expected, but as soon as sleep expires the same happens. Does anyone have any idea on a fix? Thanks in advance!
[Android Head-Units] Vampire_Dracula:
Quick question.

On my old OEM headunit I had Honda Hack installed (opening up root access). This hack also added the option of voice notifications when trying to drive with the hand brake on, and for the seat bealt warning, instead of the original beeps.

I liked the polite reminder: "Dear passenger, please fasten the seat belt!". 😉

Does anyone know if there is a way to replace the original beeps with custom voice prompts?

I need some help trying to unbrick Hizpo QF001 Roco K706 S8 model (UIS7862) from the first screen labeled "Powered by android".

The process described on "UIS7862 Firmware Recovery From Boot Loop.doc" file from that MEGA repository, seems not to work. Nothing happens, using a 4Gb pendrive as FAT32 with only the update.zip file on root directory.

Firmware update.zip file is the latest for UIS7862 dated on 20231110.

Tested with KEY1 and KEY2 cables from headunit harness...

Tested with the three USB ports... other pendrives (8 Gb, 32 Gb as FAT32, all).

Checked the steps shown here

Hi, as I published above, I am trying to unbrick my S8 unit, without success. Like you, radio shows "powered by Android".

Maybe in your case you would need to upgrade the firmware and put the firmware file update.zip in the root of your pendrive. For S8 the latest is dated 20231110. You can check the above MEGA repository with firmwares.

Regarding your text, could you help me explaining how do you make that cycle 4 times and touch with 5 fingers? Any video or text that shows the process?

No video I'm afraid, but the process is simple.. just turn ignition on/off 4 times; the 4th time you start tapping the screen with 5 fingers repeatedly (quickly) multiple times, then at some point it starts. As for updating, I tried to update from a USB flash drive but I got the checksum error and the update failed.
[Android Head-Units] Barykelo:
use the firmware from 10/13/2023, it has an OK checksum
[Android Head-Units] Serruxo:
Thanks for your help.

Radio it is not still installed in the car, so I am testing on my lab with a AC 12v power adapter, that it is running well.

The point is I switched on/off the radio 4 times, in the 4th try, I touch screen with 5 fingers repeatedly but it seems not doing nothing. Also tested pressing the RST button 4 times, and anything happens.
[Android Head-Units] catalin284:
I tried with October file now and still no luck.. update gets stuck after a few minutes, will not progress further. Same as when I got the checksum error.

I changed the wheels and I get an error on the TPMS board. I used to be able to reset the TPMS, but now I have an android unit.

Does anyone know how to reset or disable the TPMS on the Honda Civic 2019?

Thanks!
[Android Head-Units] Clyde72:
Did you recently try some app updating via Google store? I did some updating 2 days ago and there was an update for TPMS as i recall. Maybe this could help resetting...

As for disabling I suppose via system settings>apps & disabling TPMS or maybe just delete the cache to reset... the same way you would do for apps on an Android phone or tablet...
[Android Head-Units] Vampire_Dracula:
He is not asking about the TPMS app available as an independent app on our new Android HU. He is asking about the OEM TPMS sensors, installed inside the wheels, which could be reset through a menu available on the original Honda headunit, but not on the new HU.

Does anyone try to add more time options to sleep mode? 2 hours is very long for me and car battery is not new. It will be good if there is 10, 15 or 30 min. Just enough to refill GAS or grab a coffee. I assume this option is baked in the MCU. I'm just curious is this possible at all.

That video is this https://xdaforums.com/data/video/4532/4532241-25a1a68e417c415c92c81d720c24adb1.mp4

(I noticed it has been uploaded to MEGA today) and for me this procedure it is not working with my Hizpo S8. I am not able to force upgrade.

I used the cable on pin 6 of the rear connector, labeled in my case SCW2. Video shows "Steering Wheel Control 1". Also I tested with the other cable labeled "BACK CTL" that goes to pin 7.

I did like video shows, connecting those cables using the ground of VIDEO cable; the ground of GPS connector and the ground of RADIO ANT connector, and nothing happens.

Always the screen shows the "Powered by Android" screen. The blue "Android" logo that video shows, in my case does not appears, neither the recovery menu that is shown in the video no detecting any update.zip because there is not any USB pendrive connected to the radio on that video.

By other hand, that video is not aligned with the instructions written in the "UI7862 Firmware Recovery From Boot Loop.doc" file on that MEGA repo. This document has the step 1 that is not shown on the video neither the step 3 that says to press reset button. It would be good clarify which procedure is the right, or at least, specify which brand (Hizpo / Ossuret) works with, because it seems each brand has its own procedure to force upgrade in spite they are using the same UIS7862 processor.

It is very strange.

Any help will be appreciated.

[Android Head-Units] Serruxo:
Thank so much for your time making and sharing the video.

Tested again, mine does not show that seems to be the "booting animation logo" (your SKODA logo).

Nothing happens, always "Powered by android" screen, like attached picture. No recovery menu displayed. Always the same screen with that logo. Waited some time, but anything happened.

Tested with two different headunit harness:

- 1st, blue cable labeled SWC2 that goes G6 pin.

- 2nd, brown cable labeled KEY2 that goes to G6 pin.

- NO USB pendrive connected, like you.

Something is wrong in my device or there is another different procedure. Mine Hizpo S8.

In your headunit harness, have you connected G2 (yellow B+ battery) with G3 (red ACC) to your 12v AC Power adapter? I tested connecting both cables (G2+G3) and only the G2, and no differences.

Thanks again.
[Android Head-Units] Barykelo:
Yes G2+G3. The whole problem will be that HU won't switch from "Powered by android" logo to "android".
[Android Head-Units] Serruxo:
Thanks for your help. Do you think it would be defective? I think so.

In all tests done, never switched to "android" logo... always is in "Powered by android".
