I just saw your message... I am not sure 100%... but I get same issues one time.. I am not sure it was reference 0x63 .. but same screen I get.. and when I change USB cable its work okay.. can you test with several USB cable.. maybe if you have original USB cable
[Android Head-Units] Dukenukemx:
Can anyone give me instructions on how to install RedMod? Also is there a way to backup my device to restore it if the RedMod installation fails?
[Android Head-Units] Tamer amer:
Sometimes 0x63 and sometimes 0x20 and sometimes 0x11 :laugh:

I bought an expensive USB cable but still no versions of easyconnect works anyway I will sell this head unit and I will buy a new one its android 5.1 and it's screen is bigger than 8 inch ;) and it's as in this picture
[Android Head-Units] Tamer amer:
And here is another picture for the new head unit .. but I want the easyconnect to work in my AN21U because I want to be honest for the one who will buy my old head unit and not to cheat him :)
[Android Head-Units] dadosp:
yea maybe is betetr to buy new one.. I also think to buy new for me also.. Eonon or Joying with android 5.1 .. and sell this one.. form me its work okay.. but this is HU from 2014 year.. android 4.2 .. and this is okay for somebody who want just to play music, navigation and radio... and play some video sometime... but I want more :) I need skyp, youtube easyconnect with new android.. so I need better HU :)
[Android Head-Units] Tamer amer:
The problem now that most of the HU having fake android version as I heard from someone that import heasunits and sell it. He told me that most of the HU are kikat having a fake android version 5.1 or even 6.1 and that will be a big problem
[Android Head-Units] dadosp:
Wow I do not know this :D ... this is the big problem.. how I can test it? to cclick several times on android version in settings?
[Android Head-Units] Tamer amer:
Yes that's the only way to know..

I think our HU is the simple example for what I'm saying it says it's 4.4 but actually it's 4.2 ?

RedMod

Hi anyone have the update (firmware) for the 4Core android head unit

..??
[Android Head-Units] djlen_ny:
I have a Generic HU (quad core) that came with KitKat 4.4.4 preinstalled. When I began having problems, the seller sent me an "update" for the OS. After "upgrading", I then had KitKat 4.4.2 :( (backward step)

...Now, the wifi doesn't work!!! You can turn it on, but it's not really "ON"! after exiting "Settings" and going back in, it's off again. No networks appear nor can you tether it to a phone to get online.

At LEAST I need to get 4.4.4 back on, or preferably an upgrade to a newer version of Android.

Any help ANYBODY??

[Android Head-Units] Shadow128:
Hi there

it is possible to login to the google services to get the google contacs to the unit, for using the stored addresses inside of TomTom?

Or do I've to add the needed one's manually?
[Android Head-Units] dipcore:
I'm not sure about TomTom, but I were able to sync my contacts with the unit using google account.
[Android Head-Units] Shadow128:
But how do you do that?

I installed the google app, but it seems there's no possibility to sync the contacts.

If I look into account settings, there is only app data, google fit and personal data for syncing :confused:
[Android Head-Units] dipcore:
I used RedMod ROM, all needed services are built in. I just entered my google username and password.
[Android Head-Units] Shadow128:
OK, thanks for that info. Then I'll need to buy the Redmod for my CarPC :)
[Android Head-Units] Shadow128:
Thanks for that tip, now I got all contacts to my head-unit and can use them inside of TomTom :D

But one more question.

It is possible to use a OBD-BT Adapter with the Redmod Rom?

And can I use OBD and Phone at the same time?
[Android Head-Units] dipcore:
You can use OBD-BT. I bought a cheap one on aliexpress and it works fine.

But Ive never used it with the phone at the same time, so cannot tell you.
[Android Head-Units] Shadow128:
But how do I connect the OBD-BT with the Head Unit?

I tried to pair it inside of the phone app, but I think this is only for phone devices?!

And I didn't find another option to pair it?

And, what I forget to ask..

With download the Redmod-Firmware, there was a file "com.tw.service_an_21.apk". Do I need to install this?
[Android Head-Units] dipcore:
To connect to OBD I used Torque application.

I know nothing about com.tw.service_an_21.apk It's better to contact the developer.
[Android Head-Units] Shadow128:
But where's the option to connect via Torque?

With the option "Choose Bluetooth Device" I can choose only already paired devices?
[Android Head-Units] Shadow128:
HI there

I've (in my mind) actual big problems with my android device.

As I wrote, I installed RedMod Firmware and at first, everything was fine. But then I recognized, that I'd no more root access. So I tried to get root access via the new method on the first page.

So I started Aux and installed that tool. Pushed First step and rebooted the device

Then... The tool wasn't available on that device?! Also the screen was black. After Home-Button almost all symbols are black and I can see them only, if I drop down the status bar. And the device is really really slow

OK, so I reinstalled that tool and pushed second step. Also I rebooted it

But, same effects. Everything dark and really slow

So I tried to re-install old firmware (stock or redmod), but no changes.

I tried also the old Baidoo method, but it seems, that the su is locked. Don't know why

Does anyone knows this situation?

What can I try to restore the device?
[Android Head-Units] Shadow128:
OK, the problems with the black screen und slow device are solved. After restoring factory setting everything is fine and resetted.

But...

How can I get root access?

I tried with Baidu, KingRoot and RootMyAN21, but nothing is working.

Are there so deep changes in the system that I cannot root it anymore?
[Android Head-Units] dragoescu:
Redmod is rooted. Use es file exporer if you need to access file system. I don't know what is the root method but it seems that not all apps see this "root method".
[Android Head-Units] Shadow128:
OK, thats a good hint about rooted Redmod.

But I think, Titanium doesn't recognize this root method. Is there any chance to get it working?

edit:

OK, now everything's working. I tested the whole weekend several combinations with Redmod and Titanium, but now I resetted completely and install only Titanium without any other SuperSU stuff, and now its working.

Thanks for your help!!

Hope, that Torque is also running with the new system :)

[Android Head-Units] injectx:
Hi guys,

Can someone please tell me how to get the RedMod onto my Cortex A9?

I've downloaded the free version of the firmware to test the compatibility from here: http://red-mod.ru/forum/viewforum.php?f=13 but when I want to flash it, my unit reboots and just states: FLASH START, FLASH END. It's only there for a few seconds so I'm quite positive that nothing is happening. After reboot also no change in the system.
[Android Head-Units] Shadow128:
I copied both firmware files to the root of my sd-card and triggered the system update in android settings.

Afterwards it rebooted and starts flashing, nothing more to do
[Android Head-Units] injectx:
Nevermind, working now! Did a re-format of my SD card on my Android phone and just copied the 2 required files on it.
[Android Head-Units] Tt0b1:
In case anyone is having issues with the touchscreen on his device (capacitive touchscreen only), where it wouldn't recognize the touches in the correct positions or there is a blank area where no touches are recognized, I have the solution now. I was able to create a new configuration file for the goodix touchscreen controller from scratch which solves the problem. It could probably use a bit of tweaking, but it's working for now.

Stop here if you are not currently having the issue mentioned above. If your touchscreen is inverted, it is not required to flash the new configuration (check below)! I'm not responsible if you make you device unusable! Again, only do this if you have severe touchscreen problems that make it impossible to operate the unit properly! This only works for 800x480 screens!

1. Take below text and save it as a new file called "touch.cfg". Make sure there are no line breaks!

0x43,0x20,0x03,0xE0,0x01,0x05,0x0D,0x20,0x01,0x2F,0x28,0x0F,0x37,0x28,0x03,0x05,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x09,0x08,0x0A,0x1C,0x22,0x46,0x09,0x00,0x00,0x00,0xBA,0x02,0x1D,0x00,0x01,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x1E,0x5A,0x94,0xC5,0x02,0x08,0x00,0x00,0x04,0xEE,0x21,0x00,0xC6,0x29,0x00,0xA1,0x34,0x00,0x7C,0x41,0x00,0x6E,0x51,0x00,0x64,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x02,0x04,0x06,0x08,0x0A,0x0C,0x0E,0x10,0x12,0x14,0xFF,0xFF,0xFF,0xFF,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x02,0x04,0x06,0x08,0x0A,0x0F,0x10,0x12,0x16,0x18,0x1C,0x1D,0x1E,0x1F,0x20,0x21,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0xFF,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x10,0x01

2. Copy the file to the root of your sd card.

3. On your device, go to "Settings" -> "Extra Settings" -> "Touch Area Key" (the option does not seem to be available on all firmwares, so try and find one where it is available. I was using Red Mod)

4. Select "Config". It will ask you if it should flash the configuration. Tap "Okay". Then it will show another dialog box with a countdown. I think it will revert the old config if the countdown is expired, but I can't guarantee. So in case the config file does not work, there is a chance it reverts back to the old one.

5. ????

6. Profit!

In case your touches are appearing inverted, select the "Position" button and try all of the different options in there.. One of them will make the screen work normally.

Hope this helps someone :)

Hi, does anybody have a working link or a copy of the Kaier Support Tool do decrypt the Allwinner roms?

Tnx in advance ;)
[Android Head-Units] donaldta:
This indicates that both the SWC and the front panel functions are not handled using the standard Android conventions. Though I wonder what exactly the /devices/virtual/input/input1 devlink is responsible in facilitating.

While I can certainly offer kudos to you for creating a makeshift back button for your steering wheel, I'm not sure that I follow. If it is not the same in your car then how is the information also indentical? I acknowledge the exception to eventTime and downTime but I am somewhat confused.

I'm pretty sure that information from the Settings.apk is propagated from the /system/build.prop file not the /proc/version file handle.

I think your vague question had been responded with a vague answer.
[Android Head-Units] KID52:
Sorry, what I mean is right now the unit is sat on my desk, hence it isn't connected to the car. So instead of actually having a steering wheel I just use a resistor between KEY1 and Ground as that is the same as pressing a steering wheel button. I think this was even suggested a few pages back.

The results, regardless of what I have used - a real steering wheel button, pressing a front panel button, or just a resistor, all produce the same result in the Keytest app.

Hope this clarifies my previous post.
[Android Head-Units] typos1:
The app on Googleplay works with kernels above 3.1, this unit uses kernel version 3.5, so it should work (although the feedback the app gets isnt good)

DABS.com sell a DVB-T stick ( http://www.ebay.co.uk/itm/310802737212?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 ) that works with Android versions above 4.0.3 with at least a 1 Ghz dual core processor as well.

So, you have at least 2 options for DVB-T, other than the built in tuner, on this unit, at least in theory.

On all Android devices I ever seen the kernel version appears under settings/about, along with Android version (which if you tap or click on it multiple times, usually produces a little animation related to the version name - a gingerbread man for Gingerbread, an icecream sandwhich for IceCreamSandwich, a jellybean for Jellybean etc), RAM info, CPU info, build number, build date etc.

I dont know where this info is usually gathered from, but I ve altered the build.prop on devices in the past and the info under settings/about remains unaltered.

On my Newman N2, for instance, I altered the build.prop to show the device as a Galaxy S3, due to play store problems related to it being a Chinese market phone, it still showed as a Newman N2 in settings/about, despite this.

Dont know why this version would be any different, but, good as this device seems, it does appear to have some strange quirks built into it by the devs, maybe this is another.
[Android Head-Units] rfsimoes:
That is because of my vague knowlage about programing and android guts I think. I wan't to help joining pieces to solve this jigsaw but don't know how.:rolleyes:

EDIT:

Anyway, in the app description we can read also:
[Android Head-Units] :
Hey guys,

i just got my AN21U!

One question regarding the installation:

Does anybody have an instruction about how to install the unit with the included corners?

Up to know i only had units with metal-frames.
[Android Head-Units] typos1:
Did you read my post above ? !
[Android Head-Units] rfsimoes:
Yes I did.

Did you notice that in the app description you can read:

I am excited by this RTL2832U dongles because of it's multitasking ability. With one dongle you can watch TV and if you get bored with that you can go "wardriving" with SDR radio scanning.

Everybody loves all in one devices doesn't? After all, that is what Android is all about isn't it?:D
[Android Head-Units] PsychoMcSatan:
It depends on your car a bit, but generally you'll want to grab a double-din dash kit or trim ring made for your car. It basically conforms the shape of your dash to a standard double din opening as well as providing mounting points.

One thing that I think a couple others here have observed is that these Chinese radios seem to be a slightly larger double-din standard (so much for "standards"). For my Metra dash kit I was able to use a thin blade to trim off the flange around the opening and with just a touch of sanding, it fit very snug and looks flawless.

Metra and Scoche seem to be probably the most common makes and are available all over the internet for pretty much any car. Here in Toronto I was able to find a car radio install shop that had the model I needed for under $20.

Not meant as a plug for this store, but here's just an example of the kind of thing I think you're looking for:

[Android Head-Units] fcortes626:
so over all how good is this device with performance and sound quality? would you guys recommend it?

i have seen two different ones one that says Capacitive and another one TFT touch screen and both dont have tv tuner. are capacitive and TFT the same thing and which one is better? also do they support back-up camera?
[Android Head-Units] jakejm79:
TFT refers to the technology of the actual LCD display part of the screen itself, not the touchscreen overlay portion. In other words you could have either a TFT LCD resistive touchscreen or a TFT LCD capacitive touchscreen, you would have to ask the seller to specify.
[Android Head-Units] donaldta:
No, they are not the same. They are actually two different properties. There are two basic types of touch sensitive screens; resistance and capacitive. Here is an article, "Resistive vs Capacitive Touchscreen" that explains the difference. My preference is towards capacitive due to its sensitivity and multitouch ability.

The actual display properties of the LCD screen has many variants. I haven't seen anything options for this unit that suggests there it uses anything other than a Thin Film Transistor (TFT) display. Of the many LCD types, I prefer IPS because it is better suited for more color accuracy and wide view angles. Here is a fairly good article, "Everything You Need to Know About the Displays of the Android Smartphones: LCD vs AMOLED" which defines the types available.

CAN TX and CAN RX wires

Finally received a reply from my E-bay seller about the CAN TX and Can RX wires. Not a satisfactory explanation at all:

Dear cyberpapa3,

Dear friend，

So sorry for the late reply due to the vacation, Kindly tell you that you need not connect the 2 wires they are not for connect but please just roll and package them in case short out.

Best regards

- litbinthebox

Maybe someone who knows Peter Chan could ask his techs what the wires do. From what I've read, he seems to have more info about these units than any of the other sellers.

If the wires don't do anything why put them on the unit at all? HAHA

Hi guys!

I'm looking for a good android head unit for my -06 Passat and I think this AN-21 U would be my best bet. Can someone confirm this is the right device for my car: http://www.ebay.com/itm/7-Capacitive-Navigation-Android-4-0-For-VW-PASSAT-WIFI-GPS-Car-DVD-Player-Radio-/171188343369?pt=US_Video_In_Dash_Units_w_GPS&hash=item27db9ed249

And does anybody know where I could get it cheaper or would it be best to order this one?

And of course, if you know some better device, don't hesitate to point me in the right direction. Thanks!
[Android Head-Units] PsychoMcSatan:
To me, the sound quality seems fine. As for overall performance, I was upgrading from a Pioneer unit (F900BT) which is generally well-reviewed, and the difference is night and day. It may not be as polished, as you can see from this forum, but it's generally very responsive and the core hardware seems very solid. And I believe all of the variations of this unit have the input for the reverse camera.

It appears this is the "AN-21 U"-type unit that we are discussing here. The price is a bit higher than the standard unit, but that's because you have the dash mounting kit as well as the wiring harness included for your car. Well worth the price in my opinion as you won't need to manually fiddle with the pile of spaghetti wiring yourself. It appears this will fit your 06 Passat, but it wouldn't hurt to ask the seller for confirmation.

Thank you for your answer. I'll be sure to check from the seller before I take the leap :)

I contacted pumpkin_cool ebay store and Mr Rayment replied to me with a

I like girls dude!;)

I asked what were the faceplates available for those pure android 4.1 units.

Communication was very hard has he din't understand what "faceplate" meant.

In the end I was very disappointed because the faceplate I wan't:

http://www.ebay.com/itm/Capacitive-Double-DIN-Car-Radio-CD-DVD-Player-Android-3G-WIFI-GPS-Navigation-FM-/190837675821?pt=US_Video_In_Dash_Units_w_GPS&hash=item2c6ecfd72d

is only available with Cortex A8 single core and Android 2.3.

I found this:

http://www.aliexpress.com/item/2-Din-Panel-Size-180-100mm-HD-1080P-Capacitive-Touch-Screen-Pure-Android-4-1-A9/1590761357.html

very interesting unit.

Some feature stood out to me:

What do you guys think?
[Android Head-Units] KID52:
I think the screen resolution will be 800x480. When I spoke to Peter Chan and Roadmaster, they said the higher resolution was only available as an optional extra for faces with a larger screen. Apparently some car-specific versions have a 7" screen instead of a 6.2" screen, so you can pay to have the larger resolution.

I'm not sure about the "Support multi-resolution,UXGA60HZ1600*1200 max" part. The external video is via composite, and I've seen no option to set the resolution. I didn't even think composite had enough bandwidth for such high resolution images, and at 60Hz too!

As for the GPU part, they have a Mali-400 MP.
[Android Head-Units] PsychoMcSatan:
I'd noticed a few ads with comments like "soon to be 1024x600 display nice soon" so it appears these distributors can see that new hardware is coming down the pipe. Looks like a fairly safe bet as the core of this unit is probably still the "AN-21 U" just with a higher res screen swapped in.

Though they do list: Core board digital RGB888 direct drive, higher definition and clearer display

Not sure if that means different enough hardware so that the rom is substantially different than our AN-21 U's.
[Android Head-Units] donaldta:
So, I have one last question for the year. Does the SWC on the AN 21-U have the ability to mimic meta-key combinations? I ask because Android has a Quick Launch feature (although lately hidden in the Settings.apk) which allows you launch applications by pressing [Search]+[A-Z/0-9] combination. This can be useful to do things, like associating the [Search]+[v] to the Voice Search so you can initiate Google's Voice Search from a SWC or USB Keyboard (like the CarPc JoyCon EXR)

I attached a copy of two APKs that I created by using Task App Factory which brings up the Quick Launch window from the Settings control panel using Activity Manager, "am start -n com.android.settings/.quicklaunch.QuickLaunchSettings". I noticed that on certain ROMs though it does require root because the way Tasker App Factory associate the userId in the APK.

So, Quick_Launch.apk uses su to root to bypass the error, while Quick_Launch.0.apk does not for ROMs that will allow it without root access.
