What is MCU - In short: The MCU (Microcontroller Unit or, according to other sources, the Media Controller Unit) is a stand-alone computer, usually performed on a separate motherboard with its own processor, memory, and programmable inputs and outputs. Peripherals — a radio receiver (radio tuner), a DVD player, a Bluetooth hands-free device, a low frequency amplifier, and others — are connected to the MCU. Another part of the head unit - the computer running the Android OS - interacts with the MCU, transmitting commands to it and receiving responses to them. More details about the MCU can be found: https: //forum.xda-deve…ead_Unit/MCU_Explained

Motion Sensor (ban on watching videos while moving) - there is a brake detect in settings

External microphone - in the back where all connectors are connected there is a 2 pin connector.
Connecting an external microphoneHere

So that the sound does not turn off when the reverse is activated -include rewerse audio in settings and / or installation of settings program from AlexOneB

Connecting the steering wheel buttons - there are two groups: sw key1, sw key2 + need Gnd (if you had one group, then the connection is any sw key + Gnd).

Alternative launchers : Car launcher , CarWebGuru Launcher , Car Launcher AG .

Enter the hidden item "For Developers" (USB debugging) - https: //play.google.co…singlebyte.devshortcut (or similar applications). Install the application, run it, check in usb for debugging.

For all.
Added another update for mcu to the header - maybe both are the same.

Compare the files are the same.

Lander299 - jack for an external microphone
http://www.ebay.co.uk/…a27:g:tIoAAOSwvVlZlgIS

And in the cap threads written differently.
"Complete shutdown of the radio - in the back where all connectors are connected there is a 2 pin connector, put a jumper there (from the old hard disk) will turn off completely, but there will be no quick start anymore."

Has anyone checked?

I did not check, but the photo has a microphone jack.



Rep: (548)
* laci.f,
* Lander299,
I took it from the answers to Ali, so I wrote that I need to check. Although judging by the photo - this is a microphone jack. I tried to close myself - reactions 0, but my body does not load beyond the splash screen.

I asked the Chinese woman to reset the firmware and asked how to get the root.
She, radish, wrote only "No root"
One observation: until the correct time and date is entered in the system, the Internet cannot be accessed.

until the correct time and date is entered in the system, the Internet cannot be accessed.

Through the access point of a mobile phone with a curve, the date is allowed to the Internet (Velcom, Belarus).
Time is then set automatically from the network.



Rep: (2)
sandr2010, Apparently, yes.
If I am not mistaken, there was another seller of such balalaikas on Ali, who can take it from him? Try asking him to send the firmware.



Rep: (1)
Apparently we have one Chinese woman. Turned on the fool and pretends not to understand what firmware is.

And the name is probably danling meng ...



Rep: (2)
* Lander299 I have not put the radio tape recorder in the car yet, I collect the kit and look I need at home. I do not want to use it as a radio (I do not like the sound), it will work as a navigator and comp. For this, I ordered separate speakers for it, I will cut it into the visor.
It connects with home Wi-Fi, but it does not go to internet until time is determined by gps, or I don’t put it with my hands. Galku determine the time according to the network did not set.

I regulate, but the difference between the minimum and maximum is barely noticeable.

My home wifi is exactly the same. But through the mobile without problems.

"Track draw", "Radar draw" and "Reverse audio"

I can only assume: the marking of the camera, parking sensors, .....

Put this radio, I can not register all the buttons on the steering wheel. I program the volume +, the volume disappears - I register switching stations up, stations disappear down. What could be the problem.



Rep: (0)
* galrus, There, when programming a large button on the left, click on it and reprogram it.

Good day everyone. Installed this unit in the car Qashqai 2011g.v. Used used by the seller connecting adapter wires for Nissan. Everything is good, everything works. One problem: I can not configure the control from the steering wheel. I turn to the settings page, offers to select and press the action button, then writes press the corresponding button on the steering wheel, press and no reaction. What am I doing wrong? Tell me who knows.



Rep: (548)
* viruss1970,
The buttons on the steering wheel must be resistive: i. Something like this (single-group) is from Chery. Did they not work for you at work? Added a scheme from Kashkai (I do not know the year) - two-group.

* M o o n, A button that changes SWC1, 2 and 3? On the first, they did not want to program the volume plus and minus. One another interrupted. At the second volume, plus and minus could do nothing more. On the third as in the first case. I want something other than the volume so that the other buttons work



Rep: (1)
Good afternoon, I have this problem. After the ignition is turned off, there is no quick start, the radio settings are reset, Wi-Fi and Bluetooth are turned off. And sometimes it starts quickly, but more often it loads like after a complete power failure. How does this happen to you?

Thank you very much for the schemes. I am not very good at electronics. Please tell me what I specifically need to take to register the steering wheel buttons and what I should do in my case. I would be very grateful for the help.
