Hello, first time posting :) I recently bought a vertical S4 from Hizpo and I've been trying to customise the car launcher. One issue I have is that I haven't been able to successfully remove the top status or bottom menu bars. I have searched around but I can't find any mention of vertical screens or status/menu bars.

I have used various immersive fullscreen tools giving WRITE_SECURE_SETTINGS permissions to them via adb, and while they do remove the top and bottom bars, they stay solid black and none of the apps or car launchers can fill the entire screen.

Is there any way to allow the car launchers and apps to fill the entire vertical screen? Otherwise I'm pretty much stuck with a square screen!

Android Auto app, but I can't find it, maybe it's not in the new update and needs to be installed. Previously, it had to be additionally installed on the phone; when the radio was turned on, it automatically connected to the phone via Bluetooth and Wi-Fi, it was possible to output a lot of information from the phone to the radio and the sound was turned on immediately through the car speakers, without additional actions. But here in the thread earlier people asked the question of how to disable it, it’s a very annoying program. I don’t remember what, but she had some kind of problem)

Hi everyone, I have got the 6gb ram edition of Oussuret android headunit from Aliexpress and I really need help.

Everything is good but I got one big problem with oem reverse camera. My car is a 2016 subaru crosstrek, it turns out to have two different versions regarding the reverse camera adapter.

Both have a 28 pin connector, one integrates the camera signal inside, while the other one separates the signal to another 4 pin adapter. 4 pins/ wires are responsible for the camera: video + and video - (goes to a rca cable) and power + and -

Like many others reverse camera port, the camera adapter just converts the two signal wires to RCA cable and plug it in to the headunit, and the power cables are for the camera.

My car is the first one, but the headunit only comes with a 4 pins adapter, which means there any no video signal for the 28 pin port, those are gone to the 4 pin wire, so I bought an adapter that separates the rca cable and power wires out, and it should just copy every other pins.

Theoretically speaking, if I cut out the 4 pin camera adapter and attach the power +- wires to the new adapter, it should be working.

And I use a multimeter to measure the power from the 4 pin adapter it comes with, it got 6V, so I don't even need to step down the voltage.

But it doesn't work, no power comes out when I use the adapter. After several hours trying and ab test, I found that the original camera the (4 pin adapter) comes with the headunit (4 pin adapter) only supply 6v power when the 28pin(with no video pins) is plugged in to the factory harness without the adapter I bought.

The power supplied by the headunit is through an orange cable, which links to the canbus, decoder and I searched on the internet, the pin from the 20-pin canbus port is called camera power supply.

Does anyone know how to set the canbus to output 6v power like what it does when no adapter is attached? I don't know why it switched to no power, there must be some signal or no signal to receive for telling the canbus to control 6v power supply. Other features is fine with the adapter, afterall it just separates the video pins out and copy all other ports.

I am asking oussuret for details but they don't even know there are two versions of camera adapters and keep saying they need to ask technician. Don't think I can count on them.

I know it's quite complicated, any response is much appreciated!

P.S. The first picture is the pin of my 28 port, pin 11,12,13, and 20 are the 4 pins/wires for camera, thanks for internet resources

The second picture is an adapter that separates video signal to rca cable, and two power lines(+- power supply), and just copy other pins.

https://axxessinterfaces.com/product/AXBUCH-SB2

The third picture is the 28 pin port comes with the headunit, as you can see some pins are missing.

The fourth picture shows the 4 pin camera it comes with, 2 signal wires to RCA, 1 6v power wire to canbus decoder and 1 ground wire, the problem is power wire doesn't have any power if the adapter is attached

Thank you so much!!!

Does anyone have a horizontal image driver that will automatically rotate the image?

I mistakenly entered a code that turned my image vertically.

If the driver was with automatic installation, it would be super ok, because now I can't get to the factory to enter any code.

Thanks.
[Android Head-Units] molduo:
I tried, but no driver works. It boots automatically, after which the display remains black.

I managed to restart navigation only with this Chinese driver.

But the reversed image remains.

Don't you have a firmware that will boot automatically?

[Android Head-Units] molduo:
Thank you very much.

I think that if the firmware will be installed automatically, maybe the image will return.

The current firmware is compromised because I entered the wrong code, and it executed the command. Let's see what will happen after I reinstall the new firmware.

P.S. I solved the problem. Reinstalled the new firmware and the image is back.

The driver I posted must be kept, because if you installed a wrong driver, the navigation will start with the respective driver.

Thanks.

How can I get back the standard file manager - Android Explorer (DocumentsUI) that was removed by the manufacturer from the firmware?

Without it, I cannot provide full access to the USB drive through any third-party file manager, for example through ES Explorer because... There is no request to access memory, I cannot rename or delete any file through a third-party file manager.
[Android Head-Units] Barykelo:
I don't know about it being removed. What firmware do you have?

I don't know about it being removed. What firmware do you have?
[Android Head-Units] maksimal-nn:
Both on 3.10 and 3.84, everywhere there is no standard Android Explorer, which provides rights to write and change on drives, try to delete or rename something on a USB drive through a third-party file manager, for example through ES Explorer, or Total Commander, it will give you error, because at this moment the standard file manager should open and with its help you can grant write or change rights, etc. it's not there, you'll get an error.

Yes okay, maybe reacted too strong, my time still accurate till now and have/had Canbus installed, Opel.

Always had the idea that the original radio was giving the time for Canbus and OEM BC display , time was previous on my OEM display only readjusted when I putted radio on, summer/winter time and so on. This from RDS with function CT on, but depends on the radio station you are using.

What unit you have and firmware, coz saw problems with physical button lightning, with you and others, on my unit S7 with Opel dash front I can still adjust every colour I want, but also don't have that 3.3 volt, so the missing 3.3 volt is not the reason I believe for missing function of the led colour.

Maybe because missing Canbus you mentioned ?, my S7 HU display dims when it getter dark outside and put that leds on, this when my OEM display on top dashboard dims from bright to dark.

So my canbus giving the command to put that leds on.

Can say with my unit everything working, also all the buttons in CarAPP SWC to set stuff in board computer on my second Opel display, so for the money very satisfied.

[Android Head-Units] DGTheJoker:
What unit do you have? Does this work with the S4?
[Android Head-Units] Clyde72:
I have an S4 (as shown in my signature) and for the led buttons I choose red, matches OEM VW backlighting best. It is only not very bright, more like dim/fainted and brightness is not adjustable. Don't have the 3,3V indication neither but I guess 3,3V is the power the RGB contoller feeds the RGB leds.
[Android Head-Units] janolelapin:
I've S8

I don't know for the S4
[Android Head-Units] Clyde72:
@DGTheJoker fw will work on S4, mcu not but I have an S4 and latest working fw is 0104 with 1216 mcu, there is an alleged 0103 mcu for S4 but in reality it is 1216 mcu
[Android Head-Units] DGTheJoker:
I have the S4 and have some of the same issues.

Sometimes the time is wrong when NOT in sleep mode but in "hard power off" mode. I have set mine to go in sleepmode for 1 day. I already had the time based on gps location and not internet connection.

Also today after an update (20230109), I had no gps signal. Google maps didn't open and Sygic navigation app could't find gps. Few days ago, the playstore also acted weird, could't download apps. Had to find the playstore app in settings and "delete updates" from the appstore, when restarting the playstore app, everything worked as intended again.

Hi there, first post in this place, so greetings for all!

I am the owner of a S1 Hizpo radio, and got problems with the phone calls, the other person barely hear my voice because of the noise from the car and the traffic, you know what I mean.

So I`ve found this thread after looking for a solution by my own without success.

I`ve tried to plug an old mic from a hands free Parrot ck3000, but I think it does not working and the HU keeps using the mic-in, and no improve noticed.

Are you sure that your external mic is working properly? If so, maybe one solution could be a external noise cancellation mic, usb or jack, or at least change it for a cardioid lavalier type, instead the omni-directional.

Let´s see if among all we can solve this problem!

Thanks to all.
[Android Head-Units] Clyde72:
Hi, welcome to the show.

You will have to test and try, some mics won't work if they have other impedances, this is why e.g. VAG OEM mics do not work with aftermarket units... As for Parrot CK3000, tried that mic with Pioneer after market unit I had before this HU and didn't work either. Nor did the VW OEM mic.

I allready tried with a budget lavalier type and doesn't work with this HU.

The delivered external mic works and if connected it is defaulted. But problem lays with mic sensitivity overall. Still trying to alter sensitivity/volume...

Another thing is to put the external mic in a place away from the unit, the dash and front window (radio interference by Wifi/BT, fan interference, dash micro vibrations, wind sheer front window...). A pillar driver side reportedly seems an ok position for it. But this requires some dissassembling of the car's interior and leading the wire in the dash etc...
[Android Head-Units] Meteordust:
Hi,

It will be very hard to find the perfect solution, we need a sensitive mic because of the distance between mouth and mic, also a piece of software to filter car noises and mostly let voices go threw with all our different frequencies in our voices. That sounds like high end.

Most important is to make to distance from your face to mic as small as possible I believe.

I putted in my A pillar, happily in my car I can fit mic and dashcam wires easily under the dashboard and then behind the door rubber and pillar front window without disassembling too much, only cover pillar needed to pull.

People I spoke over the phone said they heard me clear but off course also hear that I'm sitting in the car, my mic is 30 cm from my face.

And yes, solution to adjust volume of mic would be already a big improvement, that should be software implemented, but will also give more car noises without decent filters.
[Android Head-Units] Meteordust:
With GPS only it depends on how quick the GPS has good signal.

My unit shows for 2 seconds 12:06 after start-up homescreen from no sleep mode, then gets updated with what I see now or believe with my hotspot first, with no hotspot it takes much longer, our RDS should also be able to get time, but think we don't have clock time (CT) implemented in our radio, because it takes network or GPS time.

Updating is always tricky with this kind of totally stripped down Android versions, do I need to clear/wipe data or not, do I need factory reset is always the question, Hizpo supplier said to me not necessary.

Myself always like fresh start after a full update.zip file, but regarding total factory reset you need to set everything again, canbus type, set physical buttons of the unit and so on and loose stuff that was installed by the supplier/Jitu before and maybe not in the new firmware from Jitu.

Your issues sounded like mine I had before, but was in my opinion related to sleepmode, Playstore not opening, Youtube not working, Sygic crashed to homescreen and so on.

My unit runs well now, also time not behind anymore, but using hotspot, but also without it GPS also update to the right time now after a clear/refresh AGPS in GPS test app on this unit.

I soldered another microphone in the place of the original.

It is 6mm capsule diameter instead of 4mm oem microphone.

I bought and tried 2 expensive lavalier microphones.

The problem is the jack. The are tts 4pole and they simply dont work on the 2 pole ts female plug. The layout (mic+and ground are different).

I did some wiring mods and tested them.

Anyway i ended with a new 6mm capsule soldered exactly where the stock mic was.

Difference is night and day

I am done with that and in general ( performance, sound quality,screen,4G) i am very happy with the unit.

I literally enjoy it more and more everyday.

It has much less bugs that my old PX5 and its 4times faster..
[Android Head-Units] jbo1:
Hello, I just received my unit yesterday and I’m having issues with the touchscreen sensitivity. The left side of the screen does not recognize light touches (Left top and bottom corners are the worst). You have to touch with a large surface area of the finger for it to register reliably. However the right side of the screen has no problem recognizing very light touches. Has anyone encountered similar issues?

I’ve been testing this out with the touch cursor on so it is easy to tell when a touch is/ is not registered. Initially I thought this may be a software issue because while I was testing it on the bench power supply I noticed that immediately after rebooting the whole screen (including the left side) would be very responsive and recognize even light touches as expected, and then after about 15-20 sec it would go back to the problematic behavior on the left side. I rebooted multiple times and seemed to have the same results. However after installing in the car the issue seems to persist even immediately after rebooting. It’s odd because I know the left side of the screen is capable of working correctly but seems like under certain conditions it has problems. I suspected maybe voltage related but voltages from car off down to (~11.5v) to car on (~13.6v) didn’t seem to make a difference. Possibly charge building up on the screen?

Its quite frustrating because in normal use many of the touches are simply not recognized making the unit virtually unusable. I have calibrated the screen multiple times and that has no effect. I haven’t tried different firmware yet, I’ve been following this thread pretty much from the beginning so I figured I’d see if any of you have experienced anything like this first. Firmware and mcu ver are 0103 currently.

Thanks for any help!
[Android Head-Units] Clyde72:
Would you have a link to the mic capsule with bigger membrane?

It's 3,5" mini-mono jack for the external mic but interesting to know that + & - seem to be inversed 🤔. I should open up my unit once to check the chassis socket wiring for external mic... but still would need the audio input specification though.

This file manager allows you to do it all. If you don't have one, something is wrong. Do a factory reset.
[Android Head-Units] maksimal-nn:
This one exists, and I know that it allows you to do this, but it is not a standard file manager that is available on absolutely all Android devices, it is an explorer only for this device and is made only for it, and it cannot provide write-change rights for third parties file managers. And the standard Android explorer (DocumentsUI) which issues write permissions has been removed on the firmware of this device. I repeat once again, try to delete something from the USB card, for example through the total commander, you will get an error. Try installing Google Drive and you will get an error again, because... Google Drive will not have access to memory, for this Google Drive needs Android Explorer (DocumentsUI), in PowerAmp you will not be able to select Murglar folders because Android Explorer (DocumentsUI) has been removed.
[Android Head-Units] maksimal-nn:
You have the “Files” application on your phone (DocumentsUI), with the help of it you get access to memory for third-party applications, and in the firmware of this device it is removed.

Hi, does anyone use dudu launcher? Is working fine?
[Android Head-Units] Aaantonn:
I use Car Launcher Pro. I really like it, but it’s a little hard to figure out the settings initially. The main disadvantage when installing third-party launchers is that when you turn on the launcher, the menu with launchers breaks down and without deleting user data from the radio, it is not possible to replace the launcher with another one. This is the situation in all recent requests.

Hey guys

Just caught up on all the issues and solutions you have posted!

I cant find anything specific for myself so wanted some advice if i can.

I have just purchased an Android stereo for my Passat B7 (2013 i think)

I have received the harness etc for connecting to the standard wiring and a raise VW-08 canbus decoder.

When I go in to set the canbus and vehicle, there is no option for a 2013 VW passat, only a 12 passat or 17 passat (B8)

I cant get any of the canbus functions to work at all (SWC, door status, AC status)

I have read people have changed the TX and RX wire on the decoder, would this be a first thing to look at?

I have also attached a video of when I go in debug mode, the info is going crazy without me even pressing any buttons.

Thanks in advance.

This is de S8 version I have bought. Do I have the latest versions MCU and System?

Unit works fine. Installed Agama Car Launcher, that works fine. Some things I like to see different:

- Torque and some other apps do not show up full screen. I want my apps to start full screen. How to. Standard Android 13 settings (display->full screen apps->..) are not available.

- Canbus does not show climate control and some other info.. Is it just not available? (doorstatus works and steeringwheel control works through the canbus interface)

- Screen brightness is bad in sunny weather.. Any possibilities on improving that?

- DSP is nice, but only user setting, the presets are awefull.. can I finetune the presets?

- Is there a way if you use CarPlay (iPhone) that the system uses the data connection of the phone?

- I want to buy some Apps, but android keeps telling I have a billing problem... Everything works fine on other devices (ChromeBook, SmartTV, etc).

Sorry if things were previously answered, I queried the forum, but couldn't find proper answers..

That's about it.

Hi

I dont have the option of anything other than a 12 passat or a 17 passat
[Android Head-Units] Aaantonn:
So maybe (12 Passat) this means from 2012 and up? I’ll tell you one thing, it doesn’t matter what year I install it, since the Passat B6 and B7 are identical electronically, there are no differences at all, but the wrong canbus plays a role. When installing, I didn’t change anything with the wires, the only thing, as shown above, was to disconnect the wire so that the radio would turn off when you turn off the car. Maybe the canbus block itself is not suitable.

I bought this HU today (S7 but it seems to be S8 anyway) and installed it partially already. The unit came with the 15th May FW and QF05 MCU. I read the very first 10 pages as well as the very last 10 to get easily "under the hood".

So far I have not been able to run Android Auto on my phone nor HU wirelessly (and haven't tried with the cable yet).
