It is best to connect a regulated power supply from 0V to increase the voltage.

Probably the backlight voltage converter driver to be replaced.

After selecting your canbus type, did you reprogram your buttons?

Can be done with the CarApp, SWS Study, that's what I needed to do to make it work, this on Opel.

I have a ROCO K706 model with 6gb ram and 128gb storage. I've had it for 3 days. Yesterday it was -1 degrees Celsius and the radio would not turn on. After a few minutes, the radio turned on. Replay today. In the morning it was around 0 degrees Celsius and again the radio did not start immediately after turning the key only after about a minute. Have you had such a problem. I still have 11 days to return the radio.

With my Opel canbus my steering wheel buttons are resetted, only volume still works after you activate/ select the canbus.

I needed the CarApp and then SWS Study to program the SW buttons to my needs.

Maybe my car is different but it looks like that selecting the right canbus doesn't mean that all your buttons work and assume he did the canbus in the right way.
[Android Head-Units] TomZol13:
The car stood overnight in the morning it was frost and the radio did not turn on after turning the ignition only after 2-3 minutes.
[Android Head-Units] Astralech:
I think it's a battery voltage drop problem.
[Android Head-Units] Clyde72:
It ain't the unit per se but allready turn off the unit's sleep mode to rule battery drain out. And check tomorrow morning when taking the car.

Maybe also have your car's battery, ignition & alternator checked (via OBD) if the problem persists anyhow. There is also the variable of around freezing point temps in your area now. Hard to tell what may be at cause.

I am no car tech btw but I think a car's priority is to dedicate power to ignite the motor first off all, rather than it's car entertainment system if there is an issue.
[Android Head-Units] ciscovti:
Hello, i have a strange problem since the first fimware installed in my Ossuret S1. After some starts of my Android head unit in the same day o differents days, music player stop to play my usb music and start to play internal mp3 included in the firmware.

Then if i try to choose again my usb memory:

"USB disk not available" or

"Start music play for a while and then after some seconds musiic player freeze with no playing/audio" or

"Start listen of first song and the skip every 10 seconds to next song".

In the most case, a new reboot of the unit fix the problem, but sometimes it happens with a cold start of the unit (now i have 1 day setted in the sleep settings).

I have just tried:

- Replace usb stick

- Tried to switch to usb1 and usb2 port on the unit

- Install new firmware erasing all data

- Tried different music player

- Tried no sleep, sleep 2 hours and 1 day in the sleep settings

- Tried to enable soft decode in the factory settings.

Anyone have same issue or any ideas how to fix?

Hello! I bought from this seller, he delivered 3 days to my radio tape recorder! On your car you need to look at what offer. They didn’t charge me a tax for the purchase, the postman brought the parcel home. Installation is easy, I found everything on YouTube. The seller is responsive and when I had a problem, the seller quickly helped. I took the S8 version 8g.-128g. works quickly and does not slow down. It hung once, but after changing the firmware, such problems did not arise again. The radio tape recorder is very good and priabrazil car.

I can not say that it is better or worse than others, I think it is the same. I wanted to take Teyes, but it will be more expensive than the weaker version, and as I looked on YouTube, it’s a big problem to match the canbus to the radio, and here the canbus was included. Yes this mage

[Android Head-Units] blue_one:
Hello fellas, I've bought a second unit for my RV. This time it's a S5 instead of a S8 like in my main car. It works without problems on the workbench but does not give any signs of life in the car. The car is a 2007 Mercedes Sprinter W906 with can bus. I measure 12 Volts at the quadlock connector. But as soon as I connect the canbus adapter the voltage drops to 2 volts. Any ideas?

Can bus adapter:

Hi guys, I have a Hizpo S8 6G\128G\Octacore 2ghz\Androdi12 Android 9" radio (I know...fake...it's 10!)

All updated to latest firmware and MCU March 2023.

Request:

How can I enable Toppal AI app upon waking up using the canbus button on the steering wheel of the car?Of course I have the license code and correctly activated Toppal AI app...

By default in "Setting-Voice-Voice app" was assigned as default app for command "Toppal AI" app, and I could wake up Toppal by physical button on car steering wheel.

Now this possibility has disappeared for no reason. In the list of the "Voice" app I can select some apps present, but I DO NOT see the "Toppal AI" app that I can select and then assign its management\wake up again as a default AI app with the physical button on the steering wheel , via canbus of my car.

The canbus \ buttons on the steering wheel all work without problems, I just need to be able to assign Toppal AI as the default app voice app in the list of available apps ...

Thank you!

[Android Head-Units] Clyde72:
So if it is not for the units in this thread - read the title - why did you drop it here?
[Android Head-Units] Clyde72:
Some supply wiring reversed in the van?
[Android Head-Units] MauriBixio:
Thanks for the reply.

I will try the new firmware!

The MCU version I currently use is exactly the version you indicated to me, apologies, the photo I uploaded I realized was older than when I updated the MCU files with the version you indicated, which I therefore already use.

But I doubt that it solves the "problem" that I can't set Toppal AI with the AI button on the steering wheel. Do you also have S8 radio?

Do you have a picture of yourself from the "Settings-Voice- voice apps list" section?

Does the awakening Toppal AI app with steering wheel button work for you?

In addition: with the current firmware, random, no reason, the AHD rear cam (1080P\ 25HZ) doesn't work, it writes "NO SIGNAL" on the video.

Revese input works ok via canbus decoder.

Ok also the fixed and dynamic lines of the steering, and also the parking sensors correctly show colored animation in approach, ALWAYS, even when I read "NO SIGNAL".
[Android Head-Units] Clyde72:
Some more things seem odd. Your car settings menu seems to be in Dutch, your system info in Italian or Spanish...

And there is something missing in the voice/spraak settings: the floating balloon...

I also noticed you've updated to the 2803 fw which we adviced not to do as that release is buggy. In stead of upgrading you could also downgrade to a known stable firmware. MCU won't change a thing for the Toppal mystery. MCU is an hardware shell and Toppal is software so I guess downgrading to an stable firmware version would be the best aim to solve the issue. Once downgraded and issue solved then try the latest 1404 system upgrade. Don't bother about MCU, focus on firmware.

Also check if TXZ (speech) is still present as Toppal AI needs it to function.
[Android Head-Units] Jeka1400:
Does anyone know how to fix access rights to special functions for third-party applications? With each reboot of the radio, and in some applications even without rebooting, these rights are lost and have to be turned on again.
[Android Head-Units] MauriBixio:
Thanks for your answer.

The photo in which I show the "Voice" section is taken from the web, not from my radio. Demonstrative only...

I have everything in Italian on my radio.

I currently have these files installed on the radio, firmware and MCU, sent to me from Hizpo store.

https://jitufirmwarezlink20230408.oss-eu-central-1.aliyuncs.com/update.zip

https://jitu321077708mcu230207.oss-cn-hangzhou.aliyuncs.com/mcu.bin

Which match what you see in picture,today picture (buggy firmware?)

Please, show me a link to download the right and stable one for S8 radio?

In the meantime, I ALSO download the latest firmware 14.04, then I do everything as you advised me.

A thousand thanks!!

Edit:

I also have these files available:

https://jitufirmware20230109.oss-eu-central-1.aliyuncs.com/update.zip

https://jitu321077708mcu20230103.oss-eu-central-1.aliyuncs.com/mcu.bin

which I had previously on the radio...with the same current problems though.

Toppal AI works fine, no problem, just can't wake it up EVEN with the physical button on the steering wheel.
[Android Head-Units] MauriBixio:
I noticed this too, randomly.

It didn't happen with previous firmware.

Like me you probably have the latest firmware, "NOT stable" version.
[Android Head-Units] Jeka1400:
No, I don't have the latest firmware. If I'm not mistaken from 04/08/23. (I downloaded all the firmware of this year and I don’t remember which one is installed). Works stably, but access to functions in the Macrodroid and Twilight applications constantly turns off by itself.
[Android Head-Units] Clyde72:
Show a screen shot of your car settings "voice" menu, not some screen you've found online. That doesn't tell anything about

your

unit so there is no point... could be a unit that was configured differently with an other firmware & mcu version.

Also look if TXZ is installed & running as a service on your unit. If you cannot wake Toppal up as you say it is not working fine. Toppal can be woken up by simple voice activation -"hey Toppal"- if working correctly. You don't even need an button to wake it, only your voice.
[Android Head-Units] blue_one:
It was a half burned fuse which acted like a resistor. What a strange behaviour... Never had something like this before.

Anyway the S5 works now like a charm in my Mercedes Sprinter. All can bus functions are working too. 😊
[Android Head-Units] blue_one:
I recognised this issue with the application rights since I used this device and I haven't found a solution yet. It's pretty annoying. Only way is to whitelist the app and never reboot. 😬
[Android Head-Units] Clyde72:
Not that strange if it was a fusible resistor eg. Also used sometimes in high end hifi amps. These type of resistors act as fuses to prevent fire from high current overload. They are harder to source but I like them as it is better to have such an resistor burn then having to replace 60% of an output stage with expensive components eg.
[Android Head-Units] MauriBixio:
Today picture of my radio\Voice settings.

Notes: just to buffer, I assigned to the physical button on the steering wheel, responsible for run AI app, DAB-Z and in photo "2.jpg" and "3.jpg", you see the current "Voice" apps selectable to assign to button above.

Well, I instead would like to assign to that button "Toppal AI" app, so I can wake up from that Toppal, in addition to that with the command "Hei Top" or with a floating icon on the display (which work without problems).icon that I have temporarily disabled, but which has no relationship if active or not with the Toppal\run from a physical button on the steering wheel, in any case the problem remains.

And this is currently not possible for me, Toppal app does not appear in the Voice apps list....

Inherent firmware version "no buggy", what do you recommend me to use?

In the meantime I have already downloaded the vers. "QF_20230414_x4.11.zip"

Thank you
[Android Head-Units] Clyde72:
I don't even think it is an issue. In order to get approved to legally commercialise a unit for in-car usage one would have to meet certain safety regulations. And thus logically restrictions to the units OS.

The certifications are to be found on Jitu Tech's website if I'm not mistaken...
[Android Head-Units] ghost_kato:
Hello, any chance how to hide status bar on main screen? Thanks
[Android Head-Units] Clyde72:
Maybe it simply isn't possible to assign a button to Toppal as it can be activated by speech... Why would you want a button if you can just say "Hey Top"? I personnaly can't test because I don't have SWC. I even uninstalled Toppal and TXZ as it doesn't have Dutch language support.

Search the thread, somebody tried the same with voice button on steering wheel... and also didn't work to assign that button...

As for the firmware, won't change anything for the SW button I guess as it doesn't seem to be a problem. But better upgrade or downgrade as 2803 is in general known to be buggy with a lot of users.

I sometimes would also like my car to do the driving itself but that will never happen so I continue steering and handling it myself. There isn't a "problem" with my car so I don't make it a problem.
[Android Head-Units] MauriBixio:
Physical button:

Toppal works well with the voice command "hei Top", but if for example you have the audio volume a little high, you have to lower it almost to zero to activate the Toppal awakening with the voice, vice versa, with the physical button, all the more convenient, in every situation. And I saw a video of an Italian guy who with a different one by Hizpo, but still Sx features, manages to choose Toppal in the Voice app setup (see video)

"minute 5.50 and following"

but he has a totally different Voice settings screen from us, where there is the flag for Toppal voice (perhaps different radio manufacturer, different settings)

therefore, I think it's possible to do this (I hope). And by default my radio could wake up Toppal from the physical button on the steering wheel....then function disappeared after some time for no reason.

Firmware: I try to downgrade to the previous one I have available, but ONLY firmware, NO MCU (do I leave the current one?)

And eventually I also try the latest version "QF_20230414_x4.11.zip".
[Android Head-Units] Clyde72:
Hizpo is only a reseller/distributor, like Ossuret. Can't tell if the guy from the video even has a Jitu (manufacturer of our unit) HU. Probably Hizpo/Ossuret etc also distribute other brand HU. Toppal AI is universal for (Chinese) HU. You can even get it from Google App store if you don't have it pre installed

As for the volume issue, even basic SWC has volume control buttons no?

If you downgrade fw possible it will work with the current mcu. But not sure at all! Try at your own risk. If it works the better, just leaves you to do the system upgrade.
[Android Head-Units] Clyde72:
I don't think it is possible. Maybe test other launchers to see what suits your flavour better.

I have the same VW model and screen size is big enough for me...
[Android Head-Units] MauriBixio:
Honestly, among the Firmware and MCU versions I've tried, the best and most stable files have been these:

Firmware January 9, 2023 : 20230109

MCU January 3, 2023: 20230103

that had sent me Hizpo store, to replace the default ones present in the radio, which were older (which I no longer have, in which Toppal AI ALSO worked from the steering wheel button).

So you think it's best that I downgrade these?

Toppal AI app free from Playstore????

I have Toppal apps pre-installed in the radio (two apps it seems). They weren't activated, I bought license to activate later.

Now my Crazy Idea!

Do you have a link to download Toppal AI apks full, with the possibility of activating AFTER, with my already paid code?

I thought ... try to uninstall Toppal AI from the radio (it's definitely not easy to do this, it doesn't allow using the "standard" procedure) and then install Toppal apks from scratch, hoping that being apps installed post-rom, it will be added to the apps list Voices available to be managed with a physical button on the steering wheel...or is this just a crazy idea? :D

edit:

ALL the buttons on the steering wheel of my car work correctly with the radio, I don't need the SWC apk as they communicate via the specific canbus of my car.
[Android Head-Units] Clyde72:
You could begin with a downgrade to these January versions if all worked well

Not free but I thought you can get it from the app store.

Unfortunately not

First go back to January versions and ask Hizpo if there are any updates, Hizpo is very supportive. If they sent you the April system upgrade it adds functionality to uninstall Toppal a.o. If they sent you an even newer version share it with us please
[Android Head-Units] wujek_p:
Half the success. After connecting the internet, CANBUS works. Unfortunately, the speakers are still silent. I did a factory reset and disconnected the car battery - still the same: silent... I have a factory BOSE installation. Maybe this is the cause?

In addition, the buttons on the left side (ON/OFF, HOME, BACK, +volume, -volume) stopped working.

I'm starting to hate this device. :(

I also have an old Android Car Radio from EONON and everything works fine.
[Android Head-Units] MauriBixio:
I remember that even with the January firmware and MCU version, Toppal was not awakened with a button on the steering wheel, it worked instead with stock radio rom (I don't remember which version, the radio I bought at the end of December 2022).

Toppal AI apk: apks standalone installer seems unobtainable, honestly I've never seen on playstore.

It seems it's only pre-installed,but I could be wrong,indeed,anyone has Toppal AI apks,please,upload...

Firmware and MCU files future release: sure, ANY update and MCU files I may get from Hizpo store, of course I will share here. ;)

I thought... doing a factory reset to the initial settings (1), with the current firmware and MCU update installed, so not stock, could recover the stock rom settings of the radio, and therefore also those for Toppal AI and button on the steering wheel?

For S series following steps:

(1) Car Settings-Factory-225588-ok. Erase user data.

(2) Car Settings-Factory-22558800-ok. Erase all data including factory settings.

Also..I also have to solve the rear AHD cam problem that doesn't work anymore..first of all understand if it depends on rear cam out (I doubt this) or current firmware bug of March 2023...in any case I also have a new rear AHD cam, so I just have to test and figure out...:D

[Android Head-Units] Telperion:
I do. I sent a message to the HIZPO store, I'll update you on what I hear back.

After a deep dive, the reason why we can't use ADB over USB is because this device runs in USB host mode. The only way we're getting ADB over USB is to somehow force it into device mode, and Google results about that were inconslusive.
