Installed and rooted with no issues. Can't see system directory contents with ES Explorer, but Root Browser works fine.

Got the "UI Not Authorized message" so I moved over the SystemUI app from .93 which made that go away, but then I noticed that the radio had no sound. So I moved over the radio app from .93 since I like that one better anyway and radio works again.

Android version is listed as 4.2.2 and system as 2.7.11, but otherwise it looks and behaves identically to 2.7.4 with 4.1.1. Should there be any noticeable Android differences or is there a tool that can confirm?

And no new MCUs... at least not the 7-10-2501 that I need to fix the direction of my knobs!!!!

I have a feeling that this image might just be an attempt at a joke... not sure if it was the Russians or the Chinese, but someone is probably having a chuckle at our expense.
[Android Head-Units] Skratchuk:
When I tried 4.2 there was no change at all apart from on the settings it said 4.2.2

Then I installed 2.7.11 and then it had a different launcher icons and all the stock apps where different.

Hi, it is obvious ;), but it seems that I don't have that option. I checked settings, extra settings, developer options, nada .

I guess I am running out of possibilities

It doesn't have 4.1 and 4.2 shown by default, it has 4.4 shown, but hide 4.4 and show 4.1 and 4.2 to compare the differences.

http://en.wikipedia.org/wiki/Android_version_history#Android_4.1_Jelly_Bean_.28API_level_16.29

Whenever I get around to flashing 4.2.2 I'll be doing this as well. If I remember right, can't you just change build.prop to show a different Android version? For example, I could make my Android version show as Version 867.5.309 ?
[Android Head-Units] PsychoMcSatan:
I'm going by the Google Translations of the 4pda.ru forums, but that's where I read a post about something about the SDK version being the old one, which I think implies it was built from 4.1 source.

Also KID52 mentioned that he'd been told that 4.2 has been built, but that it was still very buggy. The version I installed seems as stable as, and looks identical to, the previous build. My guess is that someone did a build.prop-type trick like the one you mention to excite the impatient forum readers.

Please help!

Hello everyone,

I am very new in this field.

I have a stereo system that I bought on eBay

Since I'm new to the forum I can not post links so you can find the model by searching eBay:

"Android 4.1 2 Din Car DVD CD Stereo Radio GPS PC DVB-T MPEG-4 ISDB-T Digital TV"

After I did FACTORY RESET the device stuck in android logo screen and gets stuck.

What can you do? Please help me.

I recently install the latest update at my all in one headunit for ford like the photo.

I can not root it with the method at post 1

I make all the steps but when im truing to write the 'su' at emulator it dennies to procced.

Any thoughts?

Any other way to root?

I want to root it for use the torque program and paire bluetooth.
[Android Head-Units] jpapadami:
People, search the thread. I just posted this issue two pages back. You need to install Superuser# before typing su in the emulator. After typing su, it will then open up superuser and ask you to update binaries. Do that and you'll be fine.
[Android Head-Units] nhdn:
What is the advantage to root? Everyone seems to want to do this..

Any thoughts?

[Android Head-Units] Filthy:
Thank you for your answer. It still says permission denied
[Android Head-Units] Skratchuk:
When you typed su does it come up if you want superuser to allow terminal permission if not im guessing rooting hasn't worked
[Android Head-Units] Filthy:
is there any chance to setup a wrong super user?
[Android Head-Units] Skratchuk:
Im fairly new to this myself but i use RootMyAN21U.1.4.apk http://www.firedrive.com/file/E685C7CC9E011746 which im sure everyone else does and as stated on other posts install superuser BEFORE step 10 not before.

once you click on step one and two on rootmyAN21U does it say successful and to reboot?
[Android Head-Units] Filthy:
Thank you for your help. Yes it says succes and im rebooting the unit.

I will perform a factory reset and try angain. To tell the truth i was install superuser from the begining
[Android Head-Units] Blaylock1988:
I just received my unit today, its the big 8" VW one with the volume knobs up top. I updated the System to 2.7.11. I noticed the dock buttons change colors if you hold down on the 4-square button on the far right of the dock. If you put it to the clear red ones you are able to change the color of the buttons by using the color wheel. I changed mine to black for now. I am going to try to put Google Launcher on soon though.

I am a little confused about updating the MCU. I have version 4.2.15-1-10-2101. Is that the latest? I have been digging through the repository and the latest I can find is 4.2.13-15-10-6501, which seems to be older than what I have if the number system is chronological. Is there any point to me updating the MCU right now?

So far I really like this thing. My only complaints are that the screen is a bit washed out and it recessed about a half inch into the unit, which seems a bit much.

UPDATE:

I just got Google Launcher installed and it runs/looks much better now. Loving this thing!

UPDATE 2:

I accidentally obtained Root on 2.7.11 Android 4.1.1. I followed the steps and it gave me the permission denied problem and was stuck on slow mode. I decided to do a factory reset and try again. After the reset I was re-downloading the terminal emulator and Root Browser and accidentally opened Root Browser. Root Browser asked for SU permission, so I entertained it and clicked allow forever...and it worked. I double checked with Terminal Emulator, typed in su and it requested SU permission; the cursor changed to #.
[Android Head-Units] booba5185:
Yes, but I have the single knob DVD version.
[Android Head-Units] jpapadami:
Post #3701 should also help you
[Android Head-Units] Filthy:
Thank you for the support. Still dont give me permission when im typing SU. I hava download superuser for playstore and an external apk but none of these two work.
[Android Head-Units] Blaylock1988:
UPDATE 3:

Having trouble with sound priorities, switching to 3rd party priority didn't help. Music apps stop playing when I go to the home screen.

UPDATE 4:

I realized that the 'double rectangle' in the status bar is misrepresenting its function, as it is really a settings/menu function (usually shown as 3 or 4 horizontal bars on most phones). This aggravated me as there appeared to be no way to pull up the running apps list since the menu button does the exact same thing as the one on the status bar. I remapped the MENU button to act as the "Recent" function and that pulls up the list of active apps. It makes switching between apps as easy as on a normal phone. This also helps bypass the issue of muted audio whenever I go to the home screen, since I don't need to go to the home screen nearly as often now.

UPDATE 5:

I discovered all of the issues I am having with audio not playing is only with the Google Launcher. Everything works perfectly fine set to 3rd party priority on the stock launcher and also on Nova launcher. It sucks because I like the ability to say "Okay Google" and search on the Google Launcher.
[Android Head-Units] Skratchuk:
Does your eq work ok with your radio or does it keep resetting every time you go in to it?
[Android Head-Units] Blaylock1988:
I just tested it with Nova Launcher. EQ stays the same even after ending it and switching between different apps and going back to radio and closing it in different combinations. No resetting EQ
[Android Head-Units] Skratchuk:
Ok thanks for the info I have no idea why mine does this only started after updating MCU maybe I'll have to try a lower one see if it sorts it.
[Android Head-Units] Blaylock1988:
I noticed that everything on my screen is stretched just a little bit wide (it came out of the box like this). Is there any way I can fix/adjust this? Is there a pixel density I can adjust?

UPDATE:

I just measured my screen, it is aproximately 7"x4" So I am guessing it is a 16x9 ratio. I think it is more than just the regular 800x480 pixels....

Has anyone managed to get crossover functionality from the head-unit such as to high/low/or bandpass filter the audio outputs? It would be great to be able to use this unit without the need for an external crossover!

From our friends new firmware with new MCU

[Android Head-Units] Blaylock1988:
I Just discovered you can map multiple functions to the same hardware key for different button-press lengths,

but it only seems to work for the custom fields labeled RESERVE

. After a key is set, long-press on the grey square and another menu will pop up that asks which action you want to pick for the alternative map select the press method, then you can select from a list of commands.

I set my MENU button to short-press as the RECENT command and long-press as the MENU command.

You can set the non-custom actions to do secondary actions, but it doesn't to do anything even though I set it correctly. Perhaps this is because of my MCU.

Yes.Is 4.2.2
[Android Head-Units] booba5185:
So I can (or should be able to, at least) flash from 2.7.11 that's Android 4.1.1 to 2.7.22? Or should I flash 2.7.11 that's Android 4.2.2 then flash 2.7.22?
[Android Head-Units] Blaylock1988:
You mentioned a new MCU but there was only the System update in your link.

UPDATE:

Don't bother with this system update. Nothing is changed except the version number. I also now have this "UI unauthorized, please contact the supplier" message that wont go away now. Reverting back to 2.7.11-4.1.1

I also lost Root. I was able to safely revert without any issues. I re-obtained Root without any problem.
[Android Head-Units] Prdie:
Still no 4.2.2 right ? All firmwares labeled 4.2.2 are in fact 4.1.1, aren't they ?

I'm looking forward for 4.2 just for the fact, that it might enable TomTom GPS on this unit. Do you think it might help ?
[Android Head-Units] Skratchuk:
So possibly another fake?
[Android Head-Units] ionutlup:
4.2.2

The system is alredy rooted only install superuser.MCU is 4.3.1

The unit in that video is a OUKU running android 2.3.

He's running the live wallpaper I wish I could run on my AN-21 U :(

The AN-21 U currently has no modules for BT dongles, AFAIK nobody has found a close enough kernel source to try to compile modules from for our unit. USB ODBII works great for me.
[Android Head-Units] Filthy:
I will borrow my neighbours usb Bluetooth (i dont know if its adapter or dongle) and ill give a try and i will inform.

Is there a way to convert my OBD2 BT to USB?

[Android Head-Units] donaldta:
The only Android headunits I've seen with an external mic are the ones made by Parrot.
[Android Head-Units] sciallo:
...And the S150 variations ... I plan on modding mine for external mike. It should be easy enough to do it. If you're not comfortable with a soldering iron, I'm sure any local repair shop wouldn't charge all that much to do it.

On a separate note:

I see a few peoples orders are delayed... Add me to the list. The seller received my return unit an is stalling on sending the new one out.. Last week, while my return was still in transit, they were already "redying my unit for shipping" now when I asked my unit is "being built and quality checked"... They must really be running low on stock.

It's all our fault!! I wouldn't doubt the second it got rooted orders spiked :)

Survey: To all those people that are here to just read about it but don't have anything to say. would still be cool to know how many bought this radio, just say "I" and maybe what motivated you to buy it... :)
[Android Head-Units] tdt038:
CA-FI units also have an external mic (caritglobal.com)
[Android Head-Units] Defender666:
I don't think the producers run out of stock, the sellers just need to take the bus and carry those devices how to prepare them for shipping lol...

I did not try TV app yet for the Stick but its an DVB-T stick in the end.

About the MIC the seller will solder it himself to the device in my opinion. Chinese sellers are very creative if they jsut make the business.

Also you may end up getting the device without the MIC port.
[Android Head-Units] KID52:
I too plan on adding the external mic, been saying that for far too long now. Especially as I'm looking at the unit sat on my desk right now...

With regards to the DVB tuner, I am aware that is what it is, but so far, I have been unable to find a suitable application for displaying TV channels.
[Android Head-Units] sciallo:
I don't know... The OUKU I just returned I bought from OUR_STYLE seller on ebay (also a few different names on ebay and other sites) was shipped directly from tonghai create electronics CO. LTD., The manufacturer... Would make the most sense for them to drop ship....

When I returned it, I had to return to the seller in mainland China, completely different address from the original return address... (If I remember right that was in Hong Kong)
[Android Head-Units] patrickoneal:
My order from newdealestore2012/light in the box finally shipped. I have a DHL tracking number, and it's been picked up. It would have been nice if they were up front about the delays, as I still suspect it was an inventory problem.

Is there any easy way to determine the CPU clock speed when my unit arrives? It's supposed to be 1.2ghz, and some others sell them at 1.0ghz.

I've already got the stuff to add an external mic, so after I get it checked out and make sure everything works, I'll install it and take some pictures if no one else does.
[Android Head-Units] donaldta:
You can install either Android System Info, CPU / RAM / DEVICE Identifier or any system identification package. The main source of information can be seen with a terminal app and "adb shell" using "cat /proc/cpuinfo".

BogoMIPS is the determined value of the running speed of the CPU by the Linux OS.
[Android Head-Units] patrickoneal:
Thanks.

I just tried cat /proc/cpuinfo on my phone, and it didn't quite give enough data. I installed Android System Info and it seems to give complete information with no hassle, so I'll install it when my stereo comes in.
[Android Head-Units] omarko:
where did u order from ? Aliexpress? How long did it take from payment to shipping?

[Android Head-Units] patrickoneal:

It took 8 days to ship, and I'm not sure how long it will take to actually get here. It was supposed to ship within one day of payment, they seem to be dragging their feet on shipping any of these.
[Android Head-Units] pakidermo5000:
Thanks !

non AN-21 U topic ALERT.

I was seriously thinking on buying the C150 because I really want the dedicated faceplate. I did not know it had no gapps. I did realise though that it is not really capacitive, I read somewhere it is resistor multitouch, and they call it resistor+/capacitor. Since it does not seem that neither the AN-21 U nor the OUKU willl release an audi faceplate, I will have to wait for the S150 to actually produce it and not only announce it...

However, I still think that it is possible to take a AN-21 U or OUKU for VW or Skoda and substitute the faceplate for the Audi one so that it fits in the cage. But I do not know where to get the faceplate for audi. Tried ebay and many places but no luck...
[Android Head-Units] ThePapabear:
Yes, i too have never seen any of the AN-21 and clones with an microphone slot on the back.

When you scroll down on this page - ww.aliexpress.com/item/NEW-Universal-8GB-6-2-LCD-Android-4-1-AUTO-VEHICLE-Car-multimedia-PC-DVD-Player/757890018.html - you will see some holes, where a slot can be placed. So i hope, i will not get fooled out by my seller and get a unit, where i can connect the hardwired microphone, i will get with my order.

I will tell and show you, what i have got, as soon the unit finally is in Austria at my home.
[Android Head-Units] JOSHSKORN:
The fact that you can only connect your phone via Bluetooth is a big drawback for me. Since you CAN root this device, can you install a custom ROM if there's one available? (for instance Cyanogenmod) Would that fix the problem?

Also, the boot time seems like a long time (for a head unit). Can you overclock this device to speed this process up? I thought about trying to overclock my phone, saw a video on it using BusyBox, Motomizer Expert and setCPU.
[Android Head-Units] KID52:
If you read the thread, you will notice that it is mentioned the system files are encrypted, so at the moment, there is no way to install, or create (as far as I am aware) a custom ROM.

The boot time is 18 seconds, which is pretty damn fast for Android. If a fast-booting headunit is what you are after, stop looking for an Android one. Even if you can overclock it, what times do you hope to achieve? Try find an Android phone that boots in the same time, and check what CPU it is using.
[Android Head-Units] KID52:
For those interested, here are some internal shots. Not the best as I used my phone, but not awful either.
[Android Head-Units] sciallo:
Yeah, what [MENTION=1915855]KID52[/MENTION] said...

Plus: Even if it wasn't encrypted installing CM on it would still remain a pretty ambitious undertaking... These units run some pretty customized hardware and therefore bootloader. At best we would be able to modify the original rom, like the OUKU experience, It would be great if at some point we could possibly get a custom kernel running, but at this state that's even far-fetched without a recovery/bootloader we can control...

None the less, with root we should be able to add kernel modules to make some things work, like Bluetooth dongles. AFAIK though nobody has put much effort towards that yet... have we figured out what kernel is running and if there is a similar kernel we can try to use to compile modules? (I don't have my radio yet but I guess I could try to start messing with files :) )

As far as boot time, really... what kind of system are you going to boot in less than 18 seconds with whatever processing power you want...

I would like to evenctually come up with a "pseudo sleep mode" for short stops using a IOIO to help detecting car state among other things. Then you'd get the feel of instant boot really just because the unit never shut off...
[Android Head-Units] PsychoMcSatan:
Do you mean just a female 3.5mm plug? The unit I got from our_style has that. The internals seem to be virtually identical to the AN-21 U as rooting worked like a charm. I'm wondering if the breakout cable I have just took advantage of a mic pin that may be on other units as well.
[Android Head-Units] KID52:
Where is the port located, is it part of the other wires, like video in etc, or another hole in the metal back?
[Android Head-Units] KID52:
I've soldered on a lead to allow me to attach a microphone.

It appears that no apps that use a microphone are avaiable for download though, that includes Shazam and Google Voice.

However, I downloaded a Google Voice APK, it installs, and does appear to pick up sound. I have yet to test is fully though.

The real test will be a phone call.
