So after following this thread for a while, I finally decided to purchase one of these units for my car (Skoda edition, with green LEDs), and now it has arrived.

I have only just unpacked it, and installed it in my car. I haven't tested all the features yet, but first impression is ok. :)

The radio reception is very poor though. By scanning it only locks to one channel in the whole FM band. The wiring harness originally came attached with the single antenna plug converter, however there were also a converter for dual fakra plugs (diversity antenna), so I opted to swap it out before installing. I'm considering swapping it back again, to see if I get better reception with the single plug converter.

I also tried to get 3G connection with a Huawei E367 modem, but I couldn't get any connection or network detection. SIM is pin locked, so I'll try and disable the pin and see if that's the problem. How do you know for sure if the embedded kernel modules will support a specific 3G modem?

I haven't rooted it yet, but I will, and I'll see if I can make a flash dump to SD card for backup. :)
[Android Head-Units] jpapadami:
Not sure if this is an accurate assumption, but by looking at the size and name of each file I think the seller just gave me a copy of the 2.6.70 firmware, which was installed on my unit by default. Do you have to reroot the device every time you install a firmware update/downgrade?
[Android Head-Units] KID52:
Silly question, but did you connect the power for your antenna? Assuming your antenna is powered of course.

Your assumption may be correct, it is unlikely that two different firmware versions have identical sizes, but certainly possible.

Yes, you will need to root again after a factory reset or installing a different firmware version.
[Android Head-Units] PsychoMcSatan:
Just checked the file hashes and they are indeed identical to 2.6.70.
[Android Head-Units] balaes:
How is it possible that two different faceplate units have the same MCU?
[Android Head-Units] jpapadami:
Looks like my assumption was correct. Anyway, I wanted to know where did you get the MCU and stock apps from? For the MCU I know you have to update it separately, but for the stock apps I always thought that the firmware upgrade does it. This wasn't the case for me when updating to 2.6.96. I've tried your sysapps zipped file (from which firmware version are they from anyway) and Shadowmike's 2.6.93 sys apps. None of the TV apps work with the SWC's prev/next. Are there any sys apps for firmware 2.6.96 available?
[Android Head-Units] shadowmike:
Mcu files and system apps are accessible, after rooting the device.

I personally installed every update from .70 and up, rooted every time. Just to get those mcu files .

Same as the system app files.

The system. Apps change every update just about

[Android Head-Units] jpapadami:
Weird because my "system > apps" directory stayed the same when going from 2.6.70 to 2.6.96. I had to use your 2.6.93 sysapps archive and replace them. Can you upload the 2.6.96 stock apps?
[Android Head-Units] cat2115:
Same as mine. No change in anything coming from stock to .96. But then the .96 mess up my time to be incorrect after car turn on.

Or, maybe I need to do factory reset and then flash .96????
[Android Head-Units] Miwer:
I don't think my antenna is powered. But if you are talking about the blue wire on the adapter, then yes of course I connected it ;)

So I tried switching back to the single plug adapter, and now I get great radio signal, and can tune to every channel. So I gotta conclude that the dual plug converter is crap.

I also tested a variety of Huawei 3G modems, to see what's working, and what's not. Here's a little list:

E367 - not working (I really wanted to use this because it's possible to connect external antenna for diversity)

E220 - not working

E1752 - working

E180 - working

So anyone know if it's possible to get the E367 working ? :fingers-crossed:

Hello,

I am thinking of getting this one:

http://www.aliexpress.com/item/7-IN...-GPS-Wifi-Bluetooth-Dual-core/1712895257.html

Due to larger screen, but I think it is a different UI to other AN-21Us? Is this going to cause me drama? This seems to be a unique model.

Would love to hear some thoughts on this before I jump in - never purchased such a thing before!
[Android Head-Units] shadowmike:
From what I remembered. It was minor ui cleaning, slight color changes.

From .70 onwards had the new launcher.

The radio, music, eq, phone/bt app switched back and forth, between system update.

[Android Head-Units] PsychoMcSatan:
The UI has changed a few times, but this looks to me to be the same unit as I've seen all those screens on my unit at one time or another. The one screenshot shows that it’s running version .77 of our firmware, so I’d say it’s safe to assume that this is an “AN-21 U”.

If I was buying now, I’d go for this one due to price and screen size, and I’ve never used the DVD. There are newer, higher resolution units out there, but this one’s quirks are all pretty tolerable.
[Android Head-Units] Nereth1:
Thankyou for your advice - I think I shall purchase it tonight then. Are there any quirks/things that they usually don't include that should be included, that you think I should negotiate for?
[Android Head-Units] jpapadami:
Here is another model to think about. You can also request it with digital tv tuner, 2 rear usbs, red leds, etc...

I purchased it! Now I only have to go through this whole thread and figure out where to start when I get it to get the most out of it ;)

I've never even rooted a mobile before so we shall see how I fare ;)

did anyone get a 3G / 4G usb modem working with this unit ?

I want to buy one of the prepaid usb 4G modems that come with x amount of data that lasts up to a year and is easy to recharge but not sure if the unit would be compatible with the modem and also, is there software required to run on the unit to log in to the telco network or does it just work right away when the unit starts and the modem connects to the network.

Bootloop on Andriod

Please help me. My unit is stuck in "Android", the booting parting. I try to follow OP first post but my unit had no Menu button to flash firmware.

I had a two knob. Right is Vol, Left is Band.

This is how it looks like
[Android Head-Units] NickNoltePop:
Solved????

I had the same problem...

Put the update files on your sd card, turn your unit off, hold down "HOME" and the " right knob" and stick a small needle or something like that fits in the right hole, above the HOME button ( a small hole)....

then the unit starts with a green text... UPDATE START!!!

Good luck

11.Reboot the unit.

same back to step no 9 all the screen blank...... how to back to normal?
[Android Head-Units] mosterm1:
I had a similar problem, that I couldn't see the dialog that asks to grant root permisions after entering su. Doing it blindly I ended up denying root permessions "forever" instead of granting them. Try to enter the settings (on the homescreen, try the "menu" button and then tap on the lower right (EDIT: I first wrote erroneously left) corner of the screen), find the app settings section and delete the user data from the Superuser app to get that fixed.

I then connected wie Wifi and adb as shown in the rooting video and fixed it from there.

Good luck, Martin

A21-U adjustable face

Hi all,

I've just recently purchased a JVC KW-NSW700 and to be honest am very underwhelmed by it. So I'm now in the market for an Android based unit :)

I've been reading through the threads on the HuiFei and the AN21-U and based on the awesome amount of info available on here and what looks like a solid list of updates being released regularly I'd almost decided on the AN21-U. But then I realised that in my car the 2 DIN slot is right at the bottom of the fascia and if the unit front face can't tilt then viewing and touching the screen is gonna be less than ideal.

Which brings me to my first question for anyone that has the AN21-U - does the front face tilt? All the pics I see online suggest it doesn't :(

I looked around and couldn't seem to find a 2-DIN Android unit that had a front face that tilted but I eventually came across a 1-DIN unit with a pop-up screen with adjustable tilt. Its an ES8300 from easyrising88 on ebay.

Its a combined WinCE 6.0 and Android 4.0.4 unit. Which brings me to a couple more questions:

1. What are the pros/cons to a pure Android unit vs a mixed unit? Will a mixed unit cause me any probs with Bluetooth, radio listening or having a fully functional Android OS on which I can load and use any Android app I want?

2. Anyone got or played with one of these units?

Any advice or thoughts anyone may have are welcomed. Also I remember from a few posts someones comment around returns and basically gambling the shipping cost that the unit is what you're after and if it ain't then just send it back and you're only out of pocket the shipping. Maybe I just take a punt! But after the JVC unit turned out to be a dud I'm a bit gun shy.

Excellent stuff from everyone on here - appreciate all the info and commentary it certainly has helped me to this point and thanks in advance for any advice forthcoming.

Cheers,

Dave

Hey, sorry for stepping in. I bought a T7019a from tradesolutions. Pretty happy with it.

I got a bit lost while reading the various threads covering ouku and it's variants.

Can someone please point out the correct thread for this unit to follow.

Looking for update files and rooting howtos/files.

I tried things already, but didn't work. Rootmy21u1.4 stopped with a parsing error...

Is it still for Android 2.3?

Please shead some light ;)

Hey guys, I finally have torque working (I think), and i only have 1 problem, for now, lol.

[Android Head-Units] booba5185:
I've done factory resets before for other reasons and this still went on, so I don't think it would help. I have to have Torque added into system\app directory to avoid the USB prompt at every boot up, so I think think that torque is getting opened before the SD card gets mounted. I'm going to see if there is any way I can delay the opening of a systems app, that's would help me in 2 ways...Boot time and this error.

Theyve sorted out the bugs, but in the process downgraded from a Samsung Exynos 1.4 Ghz quad core with 2Gb of RAM, to a dual core Telechips 850 Mhz/1 Gb RAM, drakey83 is understandably very pissed off ! Pity - it looked like it was potentially a good unit with a few bugs, now, with those specs, I wouldnt touch it.

I think your problem might be earth related, to do with the installation of the Harmon Kardon audio - someone oin the HuiFei thread had similar problems with the Bose set up on his Audi and I know that the Bose set up on Alfas needs a special adaptor to work properly with aftermarket headunits. The guy I m talking a out is "webdude12", there was a special adaptor/harness for his Audi/Bose but I think he made his own in the end, checkout this thread :

Stuck on Android logo

I Had the same problem yesterday. Received the unit just two days ago. Tried to hook it up at home first, to do some experiments before installing in my car. The unit didn't work so well in the first place - Regardless of what I was doing, I periodically got a popup error message about "google.x.x." process that closed unexpectedly. Sometimes I couldn't download anything from google play - I kept receiving an error message about "retrieving information from the server". It became EXTREMELY slow after rooting, and the TV tuner wasn't displaying a thing anymore, but an almost completely black screen. Going in and out of AUX app fixed the black screen, but it re-appeared at every boot, so I Tried a factory reset. After that, The unit worked pretty well, so, I tried rooting again, and then another factory reset just to start fresh before upgrading to 2.6.96. This time it remained stuck on Android logo forever. Tried to downgrade and upgrade to several firmware versions, with no success, until I Found somewhere in this thread that Downgrading to 2.6.70 or 2.6.60 may bring it back to life. 70 didn't do the job, 60 did. Now, after upgrading to 2.6.96 and rooting (this time STEP2 didn't work, tried several times, Had to install SUPERUSER manually) - it works better than before. No weired error messages at all. Thanks!
[Android Head-Units] booba5185:
Nope, I have a USB based OBDlink SX. I have not been able to get BT to work for OBD at all. I've seen 2 people that said they could get it to work, but neither answered me when I asked how, they just said it did. The farthest I've gotten with it was it'll SEE the OBD adapter, then when you try to connect to it it'll pop up with a prompt with "OK" "OBD" or "Cancel" all 3 do nothing.

The USB works great, I went through 2 ELMScan 5's before they sent me this SX, though. The problem with running USB is that a lot of times when the device boots up, it'll ask you if you want to Open Torque for this USB Device. This'll happen every time, regardless if you tell it to remember your selection or not. I believe this is because I'm using Torque Widgets, and they start up before Torque does, etc. The fix for this is to copy Torque's APK into the \system\app directory, so Android will treat it as a system app and "remember" your selection.

That's awesome and all, except for with the widgets starting and the external storage error (I think this is because Torque is opened before the SD card is mounted during boot), it doubles or maybe even triples my boot time. Example: Yesterday with the setup I've been talking about I drove the car and music didn't even start until I pulled out of my driveway and drove to the end of the street. After that long I removed Torque, and the torque widgets, and deleted the extra home screen the widgets were on (I now have 3 home screens all with car widget on them). This morning when my wife drove the car the music started playing before she even got out of the driveway.

After this "discovery" I'm going to reinstall Torque (normally, not as a system app), then have Tasker open torque 1-2 minutes after start up. I figure everything will be done starting up after that time, so it shouldn't cause any lag or anything along those lines. I haven't tried this yet, but I'll let you know for sure if it does work out.

Cliff notes: BT=bad USB=good. Elmscan 5=bad (works, but you get data corruption) OBDlink SX=works fine.

Torque Widgets with Torque=bad (MUCH slower boot times, lagging home screens, etc.)

Fix (potentially) = Have Tasker open Torque after boot up is complete (no Torque Widgets involved in this setup)

[Android Head-Units] booba5185:
Well that was a fail. No matter I do I have problems with Torque.opening. If I have it set up as a system app it starts up with everything else in the beginning no matter what I do, makes my boot time skyrocket and I get an external storage error. If I don't have it set up as a system app I can control when it opens Torque, but the prompt for USB comes up every boot. If I could have it set up as a system app AND control when it opens (delay it by say, 5 seconds) that would probably be a good fix. For now I just won't run Torque. It's the main reason I bought this head unit and such, but it's gotten to frustrating to deal with at the moment.
