Here comes another problem, harness from previous unit has 20 pin connector:

And now Ossuret S8 comes with 16 pin:

So I need to merge somehow 20 pin to 16 pin, or to ISO
[Android Head-Units] tofikl2:
The 4 more pins are: reverse camera (meh, it is in different socket in S8), brake (meh?) and, definitelly not a "meh" can bus transmit and can bus receive - those two I need to search the place to connect to
[Android Head-Units] tofikl2:
Answering my own concerns: diagram for S8 has place for it all: in this case can bus wires are going to socket F. So far it looks so easy, but it is a theory for now, let's see what practice will bring!

Another noobish question: how can I know which MCU version and which Display driver is for me?
[Android Head-Units] Barykelo:
The display driver is only used when exchanging for another type of display.

ok, I did the factory reset before reinstalling the firmware. But nothing changed. I also noticed that the ZLink5 apk is still the same, at least in terms of the version number and name. So I think the apk has not been replaced, which would explain the behavior. How can you replace the zlink5 apk? Deleting and reinstalling via stick doesn't work, the apk is rooted in the system.
[Android Head-Units] pamarama:
After an update of my Ossuret S8 I have ZLink as the replacement of Carletter. It mentions it has an issue with activating. The upgrade instructions on Autofather mention:

The upgrade instructions on Autofather mention:

The latest firmware are using Zlink as the Carplay default APK, if you are using Carletter before, please following:

Car Settings-Factory-8888 ok-35 phone link app-switch to Carletter- restart.

Unfortunately menu item 35 on my system is about Radio setting. Phone link is not mentioned anywhere in those setting. Can anyone tell me how I can get back to Carletter or have ZLink activated? I did have an active internet connection while trying to activate.

Hey guys. I have heard that this platform fake real RAM capacity (that 8/128 is real 6/128, 6/64 is real 4/64 etc.). There was such discussion here but nothing came out of this. Only some suspictions based on old UIS7862 specification (it supported up to 6GB of RAM at the time).

The question is if anybody has any real, solid proof? I've heard only about some ubootdata file with memory configuration which is intended to be flashed but it's not any proof to me.
[Android Head-Units] wit.cz:
you can try some adb commands to find out more info:

adb shell cat /proc/meminfo

or

adb shell getprop

adb shell cat /system/build.prop

adb shell dumpsys meminfo

adb logcat -b all -d | grep -i memory
[Android Head-Units] bloot:
Theoretically apps like fake device test and device Info HW should detect the real hardware inside.

Why S4 model have Bright screen than s8? There are any way to fix it via software?
[Android Head-Units] marjanoos:
I know those commands but I'm not 100% sure if this ubootconfig won't fool adb.

And unfortunately I don't have any K706 unit atm but maybe some friend will help me with that.

Fake device test does not pass the test.

My S1 unit was telling me that Android 12 was used.

I ran fake device test and it showed android 10 API 28 or 29.

I sent a screenshot to Hizpo and they sent me updated firmware.

Ran fake device test again and now apparently I had Android 13.

Then I installed Agama launcher and check system properties, this showed Android 10 as being installed.

So basically the update tricked fake device test.

Your welcome.
[Android Head-Units] Scale&Hardwarebox:
Has anyone's Hizpo S8 already broken down? My radio (Hizpo S8, 8GB RAM, 128GB storage) seems to have a hardware defect. A few weeks ago, it started to occasionally turn off and then restart. Sometimes it would restart several times in a row. Often it would just turn off and not come back on. The next day, it would turn on, run for a while, and then turn off again. Since I was not really satisfied with the radio, I have since bought another one from Mekede, with which I am very satisfied.

Now I wanted to install the Hizpo S8 in another car. After I connected everything, the radio started up and after 2-3 minutes, it turned off again. Since then, it has been mostly dead. Sometimes it can be turned on (you briefly see the Android logo), then it turns off after a few seconds and cannot be restarted.

Since I have already tried two different ISO adapters that show the same behavior, a defect there can be ruled out. I assume there is a defective motherboard in the radio. Has this happened to other devices? How did you respond?

I have already contacted the Hizpo Global Store and sent videos of the radio. The response was that they would look into the problem and forward it. So far, nothing else has happened. I am asking because the device is still under warranty and I want to know if they can replace or repair defective devices.

One noob question, FM does not work on this device? i installed navradio but it wont detect stations. should i enable something in factory settings or?
[Android Head-Units] wit.cz:
Check selected region in settings (like west europe etc.) and connection of your antenna. It should work as it is.
[Android Head-Units] Seba_12:
I've had this happen before. My device's software specification showed 8GB RAM, but the sticker on the processor under the fan said 6GB RAM. This device did not work well. It kept resetting. It broke down after a few months and couldn't be repaired. Fortunately, I managed to convince the seller to replace it with a new one under warranty. In the new device, the sticker on the processor said 8 GB RAM. And now the device works. It's not perfect but I'm satisfied.
[Android Head-Units] hojnikb:
Does anyone have issues with dropping the signal on things like DAB+ app or carplay? I have a feeling as if bluetooth/wifi signal drops and as such music stops playing for a moment. Within the DAB-Z app it looks like the signal drops to 0 (which it shouldn't) and with carplay the picture just freezes and music stops.

Is this a common issue? Could be a problem with some sort of interferance within the car or something like that? My unit is still running a firmware from ~2023 right now.

If you use online radio (not the paid stock), what app do you recommend?
[Android Head-Units] 3dkaj:
Hello, I thought for a long time whether I should put this in the forum because it's a radical conversion but for me it's great.

We installed an S8 in our CLK convertible - the original screen is unusable for a convertible.

After much consideration, I decided to convert it. The screen was removed and replaced with a WICECOCO 7 inch with 2000 Nits.

with HDMI connected via a USB to HDMI adapter from Hizpo

and a power supply via USBC. Now you can see something even in full sun.

Greetings kaj

Hi all. I have a device with a vertical screen. This is a 2013 Opel Astra J. CAN bus from Hiword GMF6.2S. Tell me how to change the language of the on-board computer? Also, the climate control window periodically pops up on the entire screen, how can I turn it off? And sometimes the climate control turns off by itself. The track switch buttons on the steering wheel are also mixed up (they work via the CAN bus). Can anyone share the Opel logo on black background for my device?

My device s8.
[Android Head-Units] wanxu:
Hi, any idea changing dpi of specific apps?
[Android Head-Units] tofikl2:
And here comes another problem: display in my S8 suddenly... Died. Touchscreen and system is most likely all right, as it looks like it is starting up normally and automatically starting the music which I can controll using side panel touch controlls, but the screen is dead black.

Yesterday evening the screen started to have a huge delay on touch, on another ride screen went bright white with fading in "previous screen", but controlls did not work. Today on the first try the screen went "bright" black and touch controlls worked again, yet no image out of this bright black (that time I also saw for the very first time that side panel touch controlls were brighted as well - previously they never shined, even when whole unit worked fine). And now on 2nd try the unit starts like described at the very beginning: pitch black, touch screen works. Any tips?

What I have tried so far:

- reset pin on the display unit

- remote factory reset using Google lost device app

Hi all, all of a sudden when I start the car my Ossuret S5 turns on radio automatically on very high volume, without me doing anything. Is there a way to stop this ? Please help.
[Android Head-Units] tofikl2:
Check Settings for something like a sound tab - it shall contain settings for different startup volumes for navi/radio/media/bluetooth
[Android Head-Units] nikoum:
Thank you for your reply I will look into this, but ideally I would like to stop the radio from launching automatically when I start the car, which is the way that it used to operate before.
[Android Head-Units] tofikl2:
Hmmm... In case of my S8 it simply launches whatever was opened when the radio was turning off. So maybe try to shut the radio off before leaving the car and check then, if radio automatically launches during the startup?
[Android Head-Units] nikoum:
Okay this worked as you said. Problem solved, thank you so much for your help.

Hi. I uninstalled the toppal service application and now after every restart it gives me a voice like it is on the screen. Can someone provide me with an apk file or give me advice on what to do with it? I have to keep clicking, it doesn't work immediately after clicking me ok. Thanks for the advice, I have an S4.

HI,

I have a Peugeot 407 with dual zone AC. I always only pressed the temperature control on the driver's side and it worked synchronized. Today, I pressed the button on the passenger side and the temperatures were set to a different temperature. On the screen, it shows the same temperature on both sides, but one puts out hot air and the other cold!!! On the original MFD screen, there was an option to resync the temperature controls.

On this radio, how can I do it (sync temperature control)?

Now, the only way to make the two temperatures equal is to press many times to the minimum on both sides, set the desired temperature on the driver's side and count the clicks and do the same on the other side!

I tried it but it only worked once, I did the adb command to grant permission but it no longer works, don't know why

Edit

It turns out it loses accessibility permission after fresh start, but i did execute this adb command already, any idea?

pm grant com.arlosoft.macrodroid.helper android.permission.WRITE_SECURE_SETTINGS

Update

Got it working! I had to whitelist Macrodroid from the sleep list in factory mode, and now it opens Poweramp on every fresh boot. I don't know why because I have disabled sleep mode, but well, it works now....
[Android Head-Units] Luka191:
Hello, i recently purchased a replacement screen for K706, screen does indeed work, but it shows strange image retention, or what others call burn in, i know its normal for lcd to have some level of burn after a long period of time displaying static image, but this screen burns in after couple of minutes of showing something, Maybe i need to flash some sort of drivers to fix the issue? Or is it just a low quality replacement screen, Thanks
[Android Head-Units] tunta63:
Thanks... Dumb me. I changed it on dev mode settings but completely forgot about car settings xD
[Android Head-Units] lefterisa3:
CTIA standard was the lavalier microphones i bought so i soldered accordingly. Sound became clear BUT even lower. Lost about 3db whenever the microphone was plugged.

So i had two options. Either cancel (desolder) the oem or try and replace it.

Regarding the mic i purchased.

Its a electret capacitive microphone 6mm.

Dont have any specs just bought it from an electronic shop costed 1 euro..

I didnt take any pictures. On the unit face there was a groove that the microphone should go in. The oem microphone was sitting far back and if you remember my previous post i did a yellow tube to direct the sound.

Now i stuffed the microphone in that hole and soldered 2 wires on the board had to open it slightly with a tool.

Hole was 5mm and i needed 6. Just that.

I was worried i will have to mess with the board microphone decoupling capacitors and the whole mic cirquit BUT it worked extremely well and i closed it up.

After a few days of use ( calls...voice recognition ect) they only thing i can say is i recommend doing it as the weak point appears to be the capluse itself and not the microphone board cirquit.
[Android Head-Units] blue_one:
I´ve located the microphone settings in /vendor/ect/audio_config.xml but i had no time to play around with the yet.

Anyone else having Problems with 5G Wifi on the latest Firmware (20230109)? I had no problems on older versions but now my head uni does not discover or connect to 5G Wifi anymore.
[Android Head-Units] Tarfful:
Don't know, I think my phone hotspot is setup to 2,4G.

I will try it later and let you know.
[Android Head-Units] Clyde72:
I understood audio and ground were maybe reversed
[Android Head-Units] Clyde72:
I also saw other forums with an external mic soldered directly to the mic circuit (other type HU), so even bypassing the external mic socket/connection. Still hope not to have to do that kind of thinkering...
[Android Head-Units] Clyde72:
Please try. Over hotspot I can only use 2,4Ghz. To home wifi 5Ghz only.
[Android Head-Units] Clyde72:
Just tested Shortcut Master Lite on an chinese tablet BMXC Y900 which also can not be rooted 🙁. (Also has a short thread here on Xda forum...)

Engeneering Mode can be explored and there are options like AudioVoice, AudioRecord, AudioVoiceEnhance etc but these can not be launched. I get a warning ending in "SU:not found".

So needs root access to make changes...

There is also an option "NonSleepMode" and for this I got a code from Ossuret 15935700 way back for the HU. So now I am wondering if they could or would give us a code for these AudioRecord e.g. ... Little chance I guess...
[Android Head-Units] Tarfful:
I can use 5G wifi flawless from the phone hotspot.
[Android Head-Units] blue_one:
Aye my 5G wfi is back online too. No idea what was wrong before. Thanks for testing mate.
[Android Head-Units] DGTheJoker:
Yes, your issues sound exactly like mine. What settings do you use for the time being displayed in the settings? Do you have "network time" on or do you use "network timeZONE" (gps?) ? both?

And, how long does it take for the time to update itself when you are NOT using hotspot and are dependant on the GPS signal?

I have my unit always in "no sleep" just to be sure not getting troubles with the car battery. Probably nothing bad will happen but I dont want to take that chance, it also doesn't even take that long to start up from complete shutdown. However, when in no sleep mode, the time is always at 12:06 just like you mentioned. It does correct itself after some time, usually when I start playing the radio or switch to another station, but that could also be a coincidence xD Only had this head unit for like a week now

S4 Ossuret (4gb/32gb)
[Android Head-Units] blue_one:
For our microphone issue: the internal and external microphone work in parallel mode. Somebody mentioned that the internal microphone would be disabled if the external is connected. I can't confirm that. I've connected the standard external microphone today and used a recording app. The app recorded from both microphones simultaneously. So the external microphone is not the solution if there is no way to disable the internal microphone. Maybe I also go the way to solder a different mic inside.

The microphone settings inside the audio_config.xml looks interesting too but I wasn't able to modify them. I've made the vendor partition rw and tried to push the modified xml to the etc folder. But it fails due "not enough space on the device" even if I delete the original xml from the folder before. Maybe I'm just doing it wrong. I'm more into hardware than coding. 😆
[Android Head-Units] Clyde72:
It was the seller from Ossuret who claimed external mic became default when connecting it. Also said it was better. So far the thrustworthiness from after sales support 😉. But I suppose Ossuret is more a Sales & Mkt machine rather than techies...

I never tested recording with both mics in fact, I should have... but I focussed more on volume adjustment (which doesn't do wonders when driving e.g.)
[Android Head-Units] Meteordust:

Hi, I have a S7, with fw20230109,mcu20230103.

Have automatic time network & GPS ON.

Time zone I have OFF, settled my time zone manual.

My problem before was that when I left network and GPS OFF, time was not adjusted after a NO sleepmode start, then putted it on with network connected, time was set right and few seconds later it went 4 min behind.

Depends on how quick hotspot is connected, not every day the same, but in general after booting I see 12:05 jumps to 12:06 and shortly after 2~3 sec the right time, on same moment that WIFI symbol comes in the screen.

I put my phone always on hotspot before starting the car,

Without WIFI can take 5-10 seconds longer..I assume GPS takes over.

Not sure if our RDS radio updates time like my old OEM radio did..no setting for that, normally you can set it off/on with a CT button, just like TA/TP, for traffic or news information/ bulletins while using RDS station.

For that also the radio need to be active and connected to a RDS station.

Will test tomorrow all possible variations, to be sure about RDS, radio on or off, automatic network&GPS from a NO sleepmode startup.
[Android Head-Units] Meteordust:
Did you set the rw properties the same as the original xml?, there are 9 possibilities to set or not, and will be lost when you copy a file, modify and save it with a text editor,, after saving you need to set the rw properties as original one and then copy/overwrite the original one.

Is this device properly rooted to overwrite?

I need to dig deep, years ago I played around with a rooted phone and modified all kind of files inside Android.

Never changed anything regarding the folder rw properties, that should not be needed when it is properly rooted and you have access with a mounted RW root explorer, only reeded out the rw props of the original file, made a copy, modified it, set the same rw props and overwrite the original one.

And yes also found the file you mention in vendor, not on HU device but in the update fw file, extracted it, system and vendor...dat.br, in my case to see the exact structure of the stock bootanimation.zip to make my own.

Indeed mic sensitivity can be set, looks like it, also mainboard mic to off, but when you say that both mic are active who knows if both mic and the external plug mic are not on the same input, just parallel connected, although would be a weird solution of manufacture.

It also shows possibilities of BT headsets, wired headset or AUXmic.

You needed to reinstall the firmware, coz you deleted the original audio-config file?
[Android Head-Units] popamor:
@blue_one can you edit the audio_config.xml file directly?
[Android Head-Units] fefferico:
Hi guys, thanks for this wonderful thread and the one with the firmware all in one place!

I've just installed mine which I think is a S4 by Hizpo on my Peugeot 2008 (2015 year awful Smeg) QF001.20220915.130908

I think mine was a bargain cause I bought it on Amazon.it for 219€ (shipping included) while a car workshop offered me for 780€ (item + setup)

I think I'm going to update with the version you posted on the other thread and dated to 16-12-2022, but I wanted to ask you guys a few questions:

1) I've got just parking sensors, didn't bought the camera, how do you show just the sensors image as soon as I insert the rear without having to see that black screen labeled "no signal"? I know I have no signal, there's no camera... I just want my sensors to go full screen, if it's possible obviously

2) do you know if it's possible to change the beep sound of those parking sensors? The default one is just annoying

3) when opening a door while engine is running a popup windows comes up but with Chinese text: any chance to get it translated?

4) how do we know if there's any new update for the cartablet firmware? Do we need to write to support everytime?

Thanks in advance
[Android Head-Units] Tarfful:
I'm gonna buy the same fan as you, but I have few questions:

1- How many pins has the fan connector on the board? 3 or 4? Why not the PWM model?

2- Have you solded the wires or just plug and ready, as the stock fan?

3- Did you use the same screw holes?

Thanks mate! We are follow your lead haha (next thing will be change the mic inside the HU).
[Android Head-Units] Clyde72:
Once again. This HU can not be rooted nor re-engineered so we are searching other ways to adress the mic issue a.o.

All help is welcome to crack the rooting puzzle.
[Android Head-Units] Clyde72:
B

By updating several times I noticed settings being unlocked so lets hope it will also unlock audio/mic adjustments in the future.

Though would be nice to get the unit rooted so we could replace TXZ (Speech a.o.) service with Speech Service for Google cf. Google Assistant voice activation...
[Android Head-Units] Meteordust:
Just tried to help blue_one with modifing inside Android.

My question mark was already if his device was rooted, otherwise waste of time., or you need to extract, modify and repack again, or use adb with a fully unlocked bootloader, but not going to brick my device when things go wrong and already mentioned that increasing sensitivity will also give more surrounding noises with present supplied mic by supplier, all depents on mic quality and range, filters to reconize voice.

So sorry I can't be of any help, just use a decent mic, internal or external, from inside our firmware I see it expects a directional mic.
[Android Head-Units] blue_one:
Well the unit is rooted already in fact. Just only inside the adb shell. You can do everything you want from there. The only limit are my linux skills. :D
[Android Head-Units] blue_one:
Indeed this is the right way. I´ve found out that the device has the busybox tools installed including the vi editor. So i am able to edit the audio_config.xml now. (you have to make /vendor rw first and chmod the file - if anyone else want to play with the system files. Beware that you can easily brick your unit... Nobody except your very self is responsible for that.)

But sadly no changed value had a positive impact on the microphone volume yet. I will keep testing around.
[Android Head-Units] xdsbx:
Anyone able to set Google Assista as defsult?
[Android Head-Units] Clyde72:
Same here, I don't want my unit bricked by thinkering and want to prevent others in bricking theirs. I only thinkered so far with units that had some recovery options or custom rom options just in case.

Thanks for the advice.

For me changing internal mic could be an option but my unit is in my daily car so dilemma. Getting it back out and temporarily putting a 1 din back or leave it as is... Besides I don't call much when driving and unit works well enough for my usage. So also dilemma in trying to run an external mic to A pillar as plan B without any guarantee it will improve things.
