Friends help.

I have a Universal Radio head Unit.

Do not play until the subwoofer volume control will shift finger Sub.

Then the subwoofer setting continuously reset when you increase or decrease the volume.

What to do?

Hello everyone, forgive my English, but google translator.

These are the features of my device.

r16 quad core cpu 1.6g

system version 4.5.3_20151027

DVD version 2.13.15-120xh-150417

1024 * 600 and 8 "Volkswagen Group.

I hope I can help with my data and when you take a post more if necessary shall command the original rom.

although my dipositive is closer to the forum 2nd Generation - Android 4.4.2 "AN-21U" and "OUKU" Unbranded Hybrid Units.

but if I can help and improve my device attempts to do so.

[Android Head-Units] Hisma:
hello

I am using the 2nd generation AN-21U with the quad core R16. I would like to know if others have issues re-mapping keys using the built-in key mapper app "steering wheel".

See image of what my app looks like

Clicking any key has no effect. I can't re-map any of my keys. My unit uses CANBUS for SWC so my SWC were already mapped by default. But I added some other keys I wanted to map to "key 1", and I can't re-map any of them. Also, I'd like the option to try to re-map my CANBUS SWC (for instance, a key is set to "mute" and I'd rather it do something else).

Any options here? Any have issues getting the key map software to recognize key presses? Is there an alternative app or config file I can modify? I am curious how I can check if the unit is detecting the buttons I added to "key 1".

Any help is appreciated thanks!
[Android Head-Units] dragoescu:
Hello,

Press start, press a function on the screen, press the key, repeat for others, press end. When you press end then the new key mapping are saved.

Hey,

Pretty new to the head unit side but have done a lot of customization to my One Plus. Anyway I'm having trouble accessing the Play Store and Google services on my HU I'm thinking it has to do with an update that happened automatically. I tried searching the threads but its hard on my phone. Also I'm interested in any Roms or new styles for the GUI. I'd like any help and info as I can get. See attached pics for detailed info and current GUI.[IMG="GUI"][IMG="Details"]http://i41.photobucket.com/albums/e290/msg4joe/Mobile%20Uploads/IMG_20151129_135112.jpg[/IMG][/IMG]

I really appreciate any tips

First, I want to thank mobi97 for his great work with RedMod - I love the Android Auto design :good:

Thus, I modded also the radio application to look more like an Auto app (and mobi's music app) and banned all the IMO relatively unnecessary settings into a separate collapsible panel. Also, the radio station name does not allow chinese signs any more (they occured from time to time with my radio and looked really, really weird ;) ). I also exchanged the icons with the one from the latest Android release.

[IMG="Radio App"]https://dl.dropboxusercontent.com/u/9829562/Screenshot_2015-12-09-22-27-24.png[/IMG] [IMG="Radio App"]https://dl.dropboxusercontent.com/u/9829562/Screenshot_2015-12-09-22-27-46.png[/IMG]

Currently, the wallpaper is hardcoded into the radio app. Maybe mobi97 wants to adapt my design and integrate the same switching between launcher wallpaper and app wallpaper like in the RedMod music application.

Starting from RedMod 1.8 (at least this is the one I Started with) each mod is the same firmware but with visual modifications and some tweaks. On last version he changed video driver (again) for that screen flickering and some visual modification on apps (radio, eq, music and launcher). Also I think he changed something on wifi and gps.

check the forum, you will find information how to decode and "understand" your MCU. All these values means something:

But first make sure you have an AN-21 android unit. If not you will end up with an dead (bricked) unit.

[Android Head-Units] dragoescu:
Hello,

As far as I know there isn't and there will not be an android 4.4.4 for AN-21U units. I see you had/have installed firmware 2.9.5 witch is an Android 4.2. You can try to flash again firmware 2.9.5.

If you will read this forum you will find that there is another person with inverted display and if I remember correctly that is a bricked unit (or for the moment I don't know a solution). For more information you can use "Search" function.

More information about the firmware download link and MCU are on this forum. If you read it you will find solution to your problems.

And of course you can use the original source of information: http://4pda.ru/forum/index.php?showtopic=522762&st=9860

[Android Head-Units] dragoescu:
In my opinion the flipped screen is related to display matrix and that is controlled by MCU.

Another user has problems with inverted screen controls (but not inverted screen): http://xdaforums.com/showpost.php?p=62958439&postcount=7484

You can try to use a MCU version closer to the version you have now installed but be careful. Why don't you ask the seller for the firmware? Tell him the problem and ask for a solution.

Just Google Translate it To English You Will Find your firmware 2.9.4 With Screen Resolution 1024 × 600 , You will Find Different Suppliers Find the firmware suits you among them Plus Many Other Firmware and MCU Firmware

For My Problem I Restored My Unit Back To 2.9.5 But Touch Still not Fixed , I've Configured a workaround thanks to [MENTION=2535234]logicMASS[/MENTION] Using his Method Settings->General ->Touch Area Key -> Position -> Top , it works but not perfect you can't touch your right Side Of the Screen ,

Also I've Formatted My Unit Several Times and Updated system with several 2.9.5 Suppliers and noticed that the Touch area key part Saves its data every time it doesn't clear data when system formatted So My First Thought is this a MCU Related Problem although i Never Updated MCU in My Unit and My Second Thought is a Config. File For Touchscreen Can Solve the Problem

If You Navigate By a Rooted File Explorer To Internal Memory -> System -> Usr -> idc -> U Will Find a File ( ur Model-touchscreen.idc ) , May Be IT Could be replaced I'm Not Sure

[Android Head-Units] striker1211:
UPDATE: My bluetooth is working again! After not having bluetooth for MONTHS I finally decided I was either going to fix it or buy a new unit since I think it is very dangerous to drive with a phone in your hand. So, anyways, this is what I did:

I went into Extra Settings and entered the 123456 password. Then I went to "Config Info". Once in there I saw this (from memory)

RDS [X]

Buttons [X]

BC6 [_]

NO DVD [_]

(something else haha)

.... etc etc

Basically I thought, "Hey, I didn't have BC6 before, but maybe it wasn't detected before", so I checked that, hit OK. Then hit the home button to get home. Then I held the left volume knob to turn the unit all the way off. I waited until I heard the speakers stop hissing (MCU off). Then I started it back up and it promptly froze about 30 seconds after the launcher (home screen) was launched and restarted itself. Now once restarted again I opened the bluetooth app again and as usual no joy. Nothing shown next to any of the settings (NAME, PIN, AUTO CONNECT, AUTO ANSWER) and when I click the search button no devices are found. I entered "1234" into the blank "PIN" field and tried again. Nothing. So I deleted "1234", then exited the app. So, I go back into the "Config Info" menu in Extra Settings and UNCHECKED BC6, hit OK, went back to Home, and held the power button. Waited til fully off, then turned it on again. After booting this time I went into bluetooth again just to see if anything changed and BAMMO everything is working. Right away I could see my old paired phone that I do not even have anymore listed in the available devices. So I go to the settings pane of the bluetooth app and YAY all the settings are back. My custom pin, custom name, and auto connect settings. I connect my new phone and it accepts my custom password shown on the PIN page (not factory, I had changed it from its default of 1234/0000) and now I can make a call. Everything is working great with every boot after that. Now the only problem I have found with this is that it only will retrieve my phone book from my SIM card and not the phone book on my device but that might be a configuration issue on my Galaxy S5 and not a problem with the radio.

I hope this helps someone :)
