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

[marioti]

Aaantonn thanks for answer me about guidelines of rear view camera.

I'm curious with what production date they send HU to me.
When i receive it, first thing i'm gonna disassembly it and check because my should be with fan and with control of fan. But of course it could be truth, same as android 12

Still waiting for anyone who can, say more about my question.

 

[marioti]

Or buy one directly from Jitu,...and ask for the newest one, or no deal mister Jitu

Just curious, where to buy direct from Jitu? On alibaba they make only wholesale. But the S8 unit is cheaper ca. 90USD

 

[Aaantonn]

Или купите один напрямую у Jitu, ... и попросите новейший, или нет сделки, мистер Jitu.

Take a chance and get an older model again))

I had a question, after updating the system, the voice assistant crashed, and the second time the same code does not enter, it writes the code has already been used. The seller has not responded. Can this be fixed or do I need to buy a new code?

I read on one forum that this K706 system is very bad and, if possible, you don’t need to buy it, but choose another one. But honestly, after updating the system, I have no complaints and I don’t see what is wrong with it, the components are good, it works quickly. The author directly vehemently argued that it was necessary to take another, but it seems to me that this is all nonsense, it's just that the author is not competent.

Yes Alibaba, you can buy a sample..so just one...new in box. but they charge 30 dollar express costs and tax for your country on top of it....you can avoid tax when you are a company.

Indeed unit does what I want, Sygic navi, Agama car launcher, radio, music and see F1 tv pro when on the road due work

Author is worried about security and want things above normal buyers of this unit, this with respect ..but for the money this unit performs very well ...

Android Auto doesn't seem to work for me, either via USB or Wireless. For anyone who has it working, what steps did you take to do it?

Anyone? How is it supposed to work? When I connect my phone via USB, and open the Android Auto app on my phone, nothing happens on the head unit or my phone. When I pair my phone via Bluetooth to the head unit, the Android Auto app on my phone says that a wireless connection is available, but nothing happens on the head unit or my phone.

Update: My CarLetter app doesn't have the Android Auto logo like I'm seeing the "tutorial" says I should have. Update: Nevermind, I figured it out. It's very unintuitive.

Thank you for your friendly and warm words. That is really motivating to help other on this forum.

I decompiled one of the Launcher APK's ("Gradiant Black", it's the 4th launcher from the left). These should be fairly tweakable to modify some of the underlying functionality. Nova or another launcher is obviously an option, but I like that the built-in launchers embed Navigation on the launcher screen.

Some details: The apps for Navi, DVR, ODB, and TPMS on the embedded home screen are not hard-coded per-se, they're mapped to system props which contain the target package name.

• Navi: persist.sys.maps
• DVR: persist.sys.dvr.app
• ODB: persist.sys.obd.app
• TPMS: persist.sys.tpms.app

You can change the contents of the property (via setprop) and embed any app you want in the home screen.

For the media playback widget, it keeps track of the last audio source in "persist.sys.qf.last_audio_src", and contains one of the bluetooth media, local media, or third party media player package names. Whatever the last audio source being played was, it controls via the widget.

Я декомпилировал один из APK Launcher ("Gradiant Black", это 4-й лаунчер слева). Они должны быть достаточно настраиваемыми, чтобы изменить некоторые базовые функции. Nova или другой лаунчер, очевидно, вариант, но мне нравится, что встроенные лаунчеры встраивают навигацию на экран лаунчера.

Некоторые детали: приложения для Navi, DVR, ODB и TPMS на встроенном домашнем экране не являются жестко закодированными сами по себе, они сопоставлены с системными реквизитами, которые содержат имя целевого пакета.

• Навигация: persist.sys.maps
• Видеорегистратор: persist.sys.dvr.app
• ODB: persist.sys.obd.app
• TPMS: persist.sys.tpms.app

Вы можете изменить содержимое свойства (через setprop) и встроить любое приложение на главный экран.

Для виджета воспроизведения мультимедиа он отслеживает последний источник звука в «persist.sys.qf.last_audio_src» и содержит одно из имен пакетов мультимедиа Bluetooth, локального мультимедиа или стороннего медиаплеера. Каким бы ни был последний воспроизводимый аудиоисточник, он управляется через виджет.

То есть музыкальный виджет на встроенном лаунчере может управлять разными плеерами?

You can also go to System settings - APP - launcher (which is currently installed) and open it. You will have a choice of this launcher in different colors, you can choose a car of a different color, I don’t like yellow, like a taxi)

For whom that's interested and is annoyed that display time is out of sync with atomic network clock time.

Myself don't use 4G network, but WIFI hotspot from phone.

Each time when I opened the GPS test app, time changed and was out of sync by 2 to 4 minutes, also when I forgot to put hotspot on my phone on, after that it was taken the GPS time sync by default after startup,
So first taken my right hotspot network time and changed 30 seconds later to the out of sync GPS time and was also out of sync with my OEM Opel board computer display.
Think this is also a bug, because it should take network time by default and not GPS, only when network not available it should do that, but ones it is taken by GPS it always takes GPS and changing the time regardless if network already sync the time.
With some hassle I could changed that back but needed to be sure that hotspot was always on before starting the car.

Think I found a solution.

Note, I don't use sleepmode, always have a fresh cold start, unit starts up with firmware date and time, 09-01-2023, 12:05:54.

After going in the factory 5544 GPS setting and changing the server SUPL host to supl.google.com, left port on 7275, then next on bottum information page changed satellites to GPS, Glonass, Galileo my problem disappeared.

My unit refreshing time now after a startup within 1 second of atomic clock, with or without hotspot.
The AGPS SUPL was using the Chinese host (supl.qxwz.com) and preferred some Chinese satellites for Glonass and Galileo or my changes did some corrections in de supl.xml in the firmware by changing the host/ preferred satellites.

BTW this AGPS is using server unencrypted without certificates, can't find any certificate in firmware for encrypted connections, so rather Google then the Chinese that follows me

Thank you for this info. Indeed, this helps the annoying wrong time when I start the device.

If your Car Letter doesn't have Android Auto logo...means your phone is not connected.
I don't use it, only tried it to see how it looked.

Normally it should automatically connect when you connect your phone with usb cable.
Nothing to be done on your phone...assume you tried in Androud Auto on phone to connect to a car, does it show nothing?, mean the blue connect button to add car, on bottum of page you also have wireless Android Auto off or on setting, you have that on or off ?

So hard to say what your problem is...cable, Android Auto on your phone, a setting?
You running latest firmware...updated Android auto on phone and HU?

You also don't see anything happening in your phone?, my phone gives notification when it tries to connect.

 

[Aaantonn]

Regarding the cooling of the radio, if you do not have it automatically.
I found three options:
1) Connect the fan through the amplifier wire and turn it on for the summer, turn it off for the winter. If you have an on-off button in the program. The advantage is simplicity.
2) We connect the fan through the thermostat KSD-01F 50-60 degrees. Glue the thermostat either to the processor or to the amplifier, let one of the wires go first to the thermostat, and from the thermostat to the fan. The advantage is that the thermostat is cheap, the fan works automatically without any programs, once done and forgotten forever!
3) We connect the fan through the amplifier wire, download the AutoFan application (the application is paid, it costs about $ 10)
In the application, we set the on-off temperature. The application works in the background. Plus in the ease of use, the minus is that it is not known whether the program will work on your system.
Share information if you tried to do something from the list.

I can agree now that stock fan is crap ..after a month it starts to make noise when starting the unit, like bearings without grease.
Fan is not suitable for very cold condition in my area...when car gets warmer noise disappears.

So will order the better fan also...

So will order the Sunon fan also...

I also decided to order a Sunon MC35101V1-000U-A99 12v, but I have a specific size of 35-35-10.

Well Blue One already mentioned that the Sunon will fit MF35101V21000UA99, 35x35x10, this is a low noise, but the stock fan was also low noise in my car....but fan can' t stand the cold, below zero degrees and the humidity that it is causing in the car....hope the unit can handle it better...

Ordered 2, just in case...but now I need to take HU out..that will be hard...

 

[marioti]

This Sunon is 7500 rpm, so i just wonder, is it not to loud?. I'm just wonder to mount something bigger like 60x60mm low noise / low rpm. In my case i have to connect amp blue wire to antena separator (adapter from 2x Fakra to DIN)
The idea with KSD-01F is quite good, but as Aaantonn said, it should be glued (thermo glue) direct to processor. Maybe it'll be better to glued some kind of small radiator to processor, and the thermostat on radiator. I guess also, when selecting a thermostat, it should be check the temperature amplitude in normal use

I can hear the fan if the head unit is outside the dashboard but in normal installation I can't hear it. Temperature controlled would be better ofc.

Don't bother @blue_one. Jumping in to a thread that exits for over 2 months and bash the thread starter is not something an intelligent person would do. We all know who started the thread and who we should thank for this thread and it insights .
