[General Discussion] QF001 (ROCO K706) Head Units with UIS 7862s (not FYT based)

You set it in car settings as the standard launcher and in nova?

Thanks... Dumb me. I changed it on dev mode settings but completely forgot about car settings xD

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.

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.

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.

Don't know, I think my phone hotspot is setup to 2,4G.
I will try it later and let you know.

I understood audio and ground were maybe reversed

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...

Please try. Over hotspot I can only use 2,4Ghz. To home wifi 5Ghz only.

Unfortunately I didn't find any option for mic inside there..

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...

I can use 5G wifi flawless from the phone hotspot.

Aye my 5G wfi is back online too. No idea what was wrong before. Thanks for testing mate.

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.

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

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.

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.)

I
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.

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?

@blue_one can you edit the audio_config.xml file directly?

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

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).
