[MTCB Android Head Units Q&A] 1-2-Hak:
The way I am installing the radio is copying it directly into the system/app folder. It doesnt need to check for certificates that way. Of course you have to mount the system directory read/write and the easiest way I found is use an app called FX explorer.

There is a radio.xml file under the layout folders that you can modify with Android Development Environment - visually. It will make it easier to see the graphics mods you make.

The radio I have put up is the new radio with the store station names :) So we should be able to customise this any way we want.

Onto the IOIO.... I was figuring I will just use an Arduino nano.

What I will do is monitor the power from the acc and if it is switched I will send a SWC through analog output pins to tell the unit to power on (which is actually come out of standby). I will do the same for shutdown.

That way I control the standby/power for the unit. If I want to switch if off completely I switch a relay to drop the power.

But might be able to be done via the MCU - I have asked Keylo to get this looked at.
[MTCB Android Head Units Q&A] KeiserSozeyFr:
It's strange ...

This week-end, I have to do some modifications on my app to display the buttons codes when they are pressed to test some things on my car.

As soon it is done, I will post the upgrade and you will be able to see if the codes of your buttons are different from the standard codes.
[MTCB Android Head Units Q&A] avantissimo:
All of this be strange indeed, because I thought that the steering wheel control be equal to that of the knob on the radio, that in fact works, but now I understand that they are different. Thanks for your great work. :good:

Is anybody using an external micrphone with a huifei unit? How is the quality?

HuiFei - 2 DIN Pure Android 4.2.2 A9 Dual Core Car Stereo Radio Head Unit

I'm think of giving this unit a skip because their sale service is so crap... I've been unable to get a price confirmation for over a week, with the potential of them selling over 50 units.

What happens if something goes wrong?
[MTCB Android Head Units Q&A] kwalsh24:
Yeah I never did get s response from the Rep mentioned on here, so I went to another sales person on aliexpress to order my unit. Its almost like they are selective to who they sell to, I managed to get 1 email response, asked another series of questions and then a price quote, nothing back, so I talked go a few different aliexpress sellers till I found one I was comfortable with.

My issue right now iis being impatient and kinda being intimidated by the programming that's being listed on here for various mods lol, zero clue what I'm doing there lol, I'm sure ill be fine rooting and getting twrp on, after that it will bebe new territory

Hi 1-2-Hak if i quote you for a different question. But i see you have one HuiFei Unit. Do you use an external micrphone?
[MTCB Android Head Units Q&A] Dareksa:
I use an external microphone because the sound quality from the internal MIC was very bad in my unit.

Unfortunately, the quality has improved only slightly.

Keylo sent me a new microphone and BT and I exchanged them yesterday, but it didn't resolved the problem.

Hello

I came across this thread a while ago after I had bought a SO7 head unit, I love it but there is one or two bugs that annoy me.

1. Every so often at start up it says failed to load system UI.

2. The usb device if left plugged in when turned off then on won't be recognised until its unplugged then plugged in again.

3. Is there a way to turn off the screen and still have the music/radio working? as the unit is bright even on the dimmest setting?

You can try long presing the mute button if your unit has it, though this feature is usually only on KLDs and only on 4.2.2.

Otherwise, Malaysk's ROM has the std Android on/off (virtual) button that turns the screen off with a short press.

hi, after downgrading from 4.4.4.2 to 4.2.2 the radio turned on successfully. Then i went home to download new MCU, i copied it to the SD card and came back to car. I have turned on radio, putted in SD card, and the radio gave two beeps and turned by itself off.

Now i cant turn it on:

KLD questions

1. I have read that the 'volume settings' in Factory Settings work on some units and not others. Is there a rhyme or reason to this? I am using outboard amplifiers, so maybe this is why the volume setting do nothing?

2. The feature list on my HU box says 'Dual way Mirror Link Function' - does anyone have screen mirroring working? What are you using/how?

3. Is there any good way to backup u-nrooted system so I can restore (all my work/settings) quickly if needed?

[MTCB Android Head Units Q&A] R4D3N:
Press and hold the reset button for 20 sec. After that, press the power button 2 seconds. If the unit does not start, it is not a software problem, but a hardware one.

At 0:13 you can see that some wires are stripped, maybe they touched some metal from underneath the dashboard and you shortcircuited the unit. In this case, the unit is dead (motherboard is fried).

First of all check the fuse for Radio (the one that it is in the fuse panel, above the glovebox - it should be number 7 and 41). If it's burned, replace it with a new one and try again. If the fuse is okay, I think you toasted your unit :(

I've I get my own company, I bought you :)

The PPP 2 WIDGET didn't work so I will try this Option.

I'm back on 4.2.2 because the 3G is working much better.

Only if I haven't got signal in some areas for longer time, the 3G didn't come back. Only with a reboot or if I put the stick out and in again.

Is it a solution to write a script who starts the 3G service all 15Minutes for an example?! Is it possible?!

hey so i've checked my unit and i go to recovery mode - update system - and waited for end of the update.

After update was information: "Rebooting system now"

and it didnt rebooted, so i tried another rom (android 4.4.4) with the same result.

How to turn on this unit then?
[MTCB Android Head Units Q&A] typos1:
It wont work cos the Ownice units have a different MCU. There is an app on these units that works with some VWs and shows some data from the CAN Bus system (door open warnings, parking sensors etc). It has been mentioned i this thread but you ll have to do a thread search to find where. If you have a VW and you want it working I think it should appear automatically if you have a VW and you pick the correct CAN Bus setting from factory settings.

[MTCB Android Head Units Q&A] Nova8316:
I saw it on the thread, with the guy who tried with Ubuntu and I have also an app wich display some data, but in list format with no refresh. You have to close and launch again the app to see updated data.

I was also convinced that it will be related to mcu. But I wanted to see if someone had something about it.

I have tried to see the traffic with an app SerialMonitor, and I saw some frames on the /dev/ttyS2 port, 38400. Nut it freezes when I'm trying to open /dev/ttyS3. I think it's already used by the mcu application for displaying info on the dash board. So the program will have to run instead of the MCU app and send data through the serial line to the CANBUS.

Maybe all we need is a properway to access these MCU parts from android.

---------- Post added at 02:22 PM ---------- Previous post was at 02:17 PM ----------

You on this thread ? I think I remember someone putting Ubuntu on one of these units months ago, not seen any mention of Ubuntu on the Ownice thread. All I can suggest is to try different MCU versions and different CAN Bus settings to see if it works better - dual CAN Bus dint work for most people until KK and when it did it was MCU 1.77 that it worked with, so the latest MCU is not always the one that works best, also there are several different settings for CAN Bus in factory settings, try them all, including for different manufacturers. Other than that try writing another app for it ?
[MTCB Android Head Units Q&A] Nova8316:
Yesn I have seen the Ubuntu thing on this thread and not on the Ownice. Just doing some reading on the others threads and have questions after.

The fact is my dual canbus on my vw is already working good, I just wanted to see if we could "extand it". Like trying to decompile this app and see if we can make it refresh directly or change the UI to have someting more "car friendly".

It will be good if we had a way to contact the developpers of each MCU for bugs tracking and features request.
[MTCB Android Head Units Q&A] typos1:
I think the MCU versions are all done by one development company with minor alterations for each manufacturer. You could always email the manufacturer of your unit and ask them for new features.

You can communicate with the MCU via a SerialManager object, but you'd have to grab an instance using reflection (or xposed), as they implemented the SerialManager as a native library (/system/lib/libmicrontek_serial_jni.so).
