Sure. I will be opening the unit on Monday, I will take some pics and send you and also give the instructions.
[Android Head-Units] storm83:
It's works pretty well actually. All I do is back out of the radio app once. It completely silences the radio and closes the app and then I just use spotify for my music. The SWC work great with it. Once I reboot the unit..it boots to the home screen and the radio remains off... Unless of course you accidentally go back into the radio app.. then you just back out again. But once you do it once...it should stay off until you open one of the other radio apps again.. from what I've experienced anyways.
[Android Head-Units] j2gifted:
Thanks I saw a method that a few other people used but the results were mixed and methods differed slightly
[Android Head-Units] Zaphod-Beeblebrox:
Storm83 is exactly right. Once you 'kill' the stock app, it stays off, even after reboot. Occasionally you will see reports of people having issues with certain sound sources, and it is usually related to the Android and MCU sides getting out of sync. Pressing the reset button fixes this for those that have had the problem. I personally have never had it happen.

I generally only use two audio sources: Radio, and Power amp. My music is stored on a 32GB MicroSD.

W2-A1000

Hi,

I am not an expert on Android and competent as you who are geniuses.

I have a pure Andorid W2-A9000 (Witson) with the following characteristics:

1 CPU Cortex A9 dual cored;

2 GB DDR3 Ram 1;

3 Android OS 4.1.1;

4 MCU Version 4.0.6-1-10-0101;

5 System Version 2.6.60

6 DVD version 2.13.11-hd860mc.

I want to make some questions for you:

1 Can I update with the firmware available in this thread?

2 Can I upgrade to Android 4.2 version?

:confused:

I installed the tomtom 1.3.X everything works fine except the navigation.

The supplied antenna does not hook the tomtom GPS and the map does not work (slides). Is there any solution to run the tomtom on this device?

Thank you all and sorry for my english.:crying:
[Android Head-Units] Djripper66:
Yes I have works great but would love to get the lastest mcu files so I can update that too
[Android Head-Units] jpapadami:
I guess that you can't root it, since you can't get to the MCU directory to tupdate? I'm wondering if the Baidu russian ver 2.4.6 or 2.4.7 works on this firmware and if you have to perform a cleanformat firmware flash or not prior to rooting? FIrmware versions after 2.7.35 require a cleanformat before root, so I'm wondering if it the same for 2.8.X versions or not.
[Android Head-Units] cool_head:
As I like you very much, here it is the 2.8.3 MCU files: https://dl.dropboxusercontent.com/u/95210964/MCU 2.8.3.rar

cheers.
[Android Head-Units] gyaku_setsu:
Good to know! Thanks guys! At least they were smart enough not to wipe settings like that on reboot. My Parrot Asteroid Smart was close to perfect in that respect with a few Tasker tweaks, but this sounds a lot easier.

So just to be clear, you don't have to start the radio every time the unit boots to allow SWC and sound to go through from other android apps... you just have to do it once ever and it will stay like that? Makes me wonder why people were complaining about it so much...
[Android Head-Units] storm83:
That is correct... do it once and it should be good. I did have an issue every once in while where my sound on Spotify would not work. I would just go back into the radio app and close it out again and then it would work fine. I then went into the settings and set the sound priority to 3rd party after someone mentioned it here... and I haven't had that issue since. The stock radio app still works for sound and everything with that setting... so I would recommend setting the sound priority to 3rd party.
[Android Head-Units] Djripper66:
Thank you now how do I put it on the sd card do I have to extract every one of those zip files or just the main one and what is the process of installing the mcu on the updated 2.8.3 firmware? Thanks again :)

---------- Post added at 07:02 AM ---------- Previous post was at 06:43 AM ----------

If you do a clean install and I have been using the original mcu because I'm not sure how to update it and now thanks to cool_head I now have them just need the steps. When I updated to the 2.8.3 and rooted it with the new Baidu worked great the only thing is I am have the radio switch channels some times and the pesky red ui warning but other then that works fine

---------- Post added at 07:17 AM ---------- Previous post was at 07:02 AM ----------

Also if I run the com.tw.service_a5a4.apk will this get rid of the red ui warning? And will it creates any other problems? And again thank you for your help is there one place where I can get all of these latest updates for firmware and mcu updates where you are getting these new new ones like 2.8.3? If you could answer those 2 questions and how to place the mcu file and update it then that would be so great and make me one very happy person :):)
[Android Head-Units] cool_head:
You have to extract to the root of the sdcard the correct MCU for you unit.

To get rid of the red ui warning you only have to replace the com.tw.service_a5a4.apk to a patched one. For doing this your unit needs to be rooted.

cheers.
[Android Head-Units] Djripper66:
Do you know if it's root able with Baidu Root and what firmware updates and mcu updates there are? And have you been able to find a link?
[Android Head-Units] cool_head:
Yep. And it seems stable. The rooting method is the same as .39 and .42.

BTW, if someone have the MCU variant (H/W version) x.x.x-1-xx-xxxx with BC6 module and EQ reset problems, you can flash with the 4.3.9-14-xx-600101 MCU. I've tested all MCU's in my frankenweenie unit and had this amazing discovery. :victory:

cheers.

[Android Head-Units] Djripper66:
I am a little confused to which one i use my details are

Android version: 4.2.2

MCU Version: 4.0.6-1-10-0101

System Version: 2.8.3

so which file would I extract?

DVD Version : 2.13.11-1200xh
[Android Head-Units] cool_head:
You can extract and flash the file 4.3.9-1-10-210101.

cheers.

Updates?

I have searched in this thread and I can't find an answer. Where are the official updates to these units posted at originally? If I want to download the update to my unit (presently MCU 4.3.8.1-3-10-040201 and SYS 2.7.39) from the official source, where do I go? Is there an official changelog so I can decide if it's a risk worth taking or not? Who is developing these updates? I know this is a lot of basic questions, but I got my unit very recently and it came with a very generic owner's manual and I am trying to understand how I'm supposed to know when updates roll out. Where do I go to download 2.8.3?
[Android Head-Units] Djripper66:
Cheers
[Android Head-Units] cool_head:
Hey man we're talking about a chinese device.. the only support we have are each other.. there is no official source. You have to stay tuned in the forum to see if someone posts new stuff. And then, when flashing, you're on your own.

cheers.

---------- Post added at 07:56 AM ---------- Previous post was at 07:47 AM ----------

Like i said before, the only way to permanently root 2.8.3 is installing the full format firmware after installing the main firmware and then install baidu 2.4.6.
[Android Head-Units] Djripper66:
So does that mean I install the mcu that you gave me then install the firmware 2.8.3 then install Baidu 2.4.6 then press root then it will work?

---------- Post added at 05:49 PM ---------- Previous post was at 05:43 PM ----------

Also the full format firmware is that the one at https://yadi.sk/d/wPDAG-Djbhgxx ?

---------- Post added at 06:47 PM ---------- Previous post was at 05:49 PM ----------

In other words what is full format firmware and do you have it for 2.8.3?
[Android Head-Units] jpapadami:
Is there a modded 2.8.3 tw.services apk to go along with the firmware? :)
[Android Head-Units] Djripper66:
Where can I get that do you have a link please? and is it as simple as just install the apk and then all good? Sorry just don't know a heap about these an21u and their firmware.

[Android Head-Units] MileHighClubAV8R:
I think I understand. The new firmware that is "coming out" is not an official release from the manufacturer, but folks here in the community are extracting the firmware from newer models of head units as they come shipped with more recent versions of firmware. Is that a correct assumption?
[Android Head-Units] ZexGX:
No.

The members are likely contacting the vendors (usually in China) who then contact the manufacturer in China for the system software. That is typically how software for these makes its way onto posts on XDA or the Russian forum.

I wish someone would bring out a nice slick looking android dvd player like that new one with all screen and just touch buttons on the side that is universal like not locked to something like VW and it should run android 4.4 and should be able to be rooted by an English version of Baidu which as far as I know does not exist and Be at lease a 1080p res with a quad core 3 gb ram obd2 supported and should have wireless ac. In my opinion lol that would be one wicked dvd player

[Android Head-Units] Djripper66:
Well if I had knowledge I would build one myself but unfortunately I'm not smart enough lol
[Android Head-Units] Zaphod-Beeblebrox:
I hated coming across as a smart-a$$ in my first reply, but your follow up is unfortunately exactly right. To get the specs you are talking about, you are likely going to build it yourself. The good news, this is not quite as daunting a task as it might once have been.

I've been tinkering with in-car media & nav for about 20 years now. I've had a variety of DIY/Home brew computers on consoles, laptop mounts, and A/M head units (this is my 2nd Android based one, have had several Win CE ones as well). I've also made a couple of attempts at hacking my dash bezels up and mounting tablets.

For a simplistic, I just want to install a radio and use it standpoint, this AN-21U is the best I've had so far. From the "I've got the the best screen/specs hardware perspective", my fiberglass'd up Nexus 7 install was the best. Unfortunately, My fiberglass skills are practically non-existent. The project went unfinished and only partially functional when I ran across the AN-21U.

Part of me would like to resurrect the tablet install (With something new, based on the Tegra K and a QHD screen :)), but the AN-21U gets my basic needs handled. If you search around things like Ebay and Aliexpress, you'll see that there is some movement towards 1024 x 600 screens, but I will likely hold out for a 1280 x 800 or higher before I upgrade out of the AN-21U
[Android Head-Units] wanxu:

[Android Head-Units] Djripper66:
All good and yeah I was planning on sticking with the an21u and the only way you could build a proper unit would probably be to have a large business with lots of intelligent people to design the motherboard and a chip making machine but being able to make one with those specs are possible just no manufacturer has done it yet and even if they did it would probably be some Chinese fake android 4.4 but really it would be 4.1 lol

[Android Head-Units] Journeyman91:
Hey guys,

So u received my unit last week and finally got time to install it. I will post some more insights and thoughts on the performance of the unit later. But for now I have another question:

Everything functions fine (radio, steering wheel control, unit turns on when car start, turns off when car off) so it seems I connected every wire to the right spot. BUT: I can not turn on the radio once the car is off. Shouldn't it work since it is directly connected to the battery (Canbus)? You guys have the same problem?
[Android Head-Units] srt42b:
Can someone rehost the Firmware download?
[Android Head-Units] ZexGX:
I don't know if the layout is the same. Nobody has posted pictures of what 2.8.3 looks like. Can you show us pictures?

It supports auto scanning, I think.

You can set radio station names by what the radio stations are broadcasting. The 2.7.42 radio had custom preset names but the presets would not remember the frequency number.

I don't really see why you wouldn't give it a shot, considering you can make a backup of your current one. Let me know.

New board

The motherboard on the aliexpress is no longer available, do you know where I can buy a new board?

Thanks
[Android Head-Units] ZexGX:
I explained this in a PM to you in more detail, but I'll go over it here as well. There are 2 wires that the headunit uses for powering on:

+12V power at all times (from battery)

+12V switched power (from ignition switch)

The headunit needs +12V on the ACC (switched) wire on the headunit wire harness, to be able to power on/off. When you start the car, the ACC (switched) wire gets +12V. When you turn off the car, the ACC (switched) wire becomes unpowered. You cannot have the headunit turn on/off with the car AND be able to turn it back on with the car turned off.

[Android Head-Units] Journeyman91:
Hi ZexGX,

Thanks for your quick answer! You are absolutely right about the two wires and their function.

The way I connected the cables the unit works exactly as stated. Nevertheless it is actually really usual that radios turn on even when ignition is off... My old aftermarket radio in my old car did and the factory radio in my new car I had set up till yesterday did as well (turning on/off with ignition automatically and on/off without manually). That's why I wondered if it is possible with this aftermarket radio aswell...

PS: Thx for your PM aswell.
[Android Head-Units] gyaku_setsu:
You are right that this is unusual, but android units (apparently) consume a lot of power in standby, and honestly, it is probably better that it doesn't turn on without the ignition on as well. Even the Parrot ASTEROID Smart won't let you turn it on without the ignition due to the power requirements.

In a perfect world, you would be able to keep the Android OS chips on all the time or for a few days between full power-ons (they consume tiny amounts of power compared to what a car battery has in reserve) and the ACC wire would just act like the power button on a phone by turning the screen off (which should—in theory—turn the MCU off as well) and maybe disabling bluetooth/wifi until on again. But who thinks about these things... certainly not electronics manufacturers ;)

Does anyone know if pushing the power button turns off the MCU as well? Does that affect bluetooth? Because if not, it would be kinda cool to wake the system by programming Tasker to emulate the power button command when your phone connects to it via bluetooth..... but I can see that being really buggy.
[Android Head-Units] ZexGX:
I'm a bit surprised. In the 3 vehicles I own, and the 9 or so vehicles my parents owned while I was growing up (various/multiple: Chevrolet, Ford, Mercedes Benz, Toyota, Kia, Mitsubishi, Jeep) none of them actually allowed you to listen to the radio after opening the vehicle door with the key in the off position. The absolute most functionality I recall the headunits would have when the key was in the OFF position (or not inserted) upon entering/exiting the vehicle, would be to function as a clock. Perhaps it's a brand thing, or a new thing.
[Android Head-Units] Miwer:
Actually the MCU is on all the time the unit is connected to power, even when the unit is "off". It has to be, in order to detect keypresses and ignition on/off events. The MCU may go into low power sleep mode to save power, but it will always be "on" so to speak. However I do think the BT module is shut down when the unit is off (that would be my design choice anyway if I were to design such a system).
[Android Head-Units] cool_head:
I own a VW Passat with a RCD310 headunit, and I can turn on the radio without the key in ignition. Then, the system turns off 20 minutes later for the case you forget to turn off again. :good:

I am thinking about purchasing the most recent model of this system. Can it be rooted and do you guys think it is a good buy? Is it stable and is it good quality? The main reason I want it is Google Maps and Google Play Music. I considered the Parrot Asteroid Smart, but the processor is just too weak. These generic Chinese units are nearly up to date with today's smartphones. Last question, do you think this is the best generic model available?

Thanks!
[Android Head-Units] Djripper66:
Well once you work out all the perks then yes its just about the best android dvd player you will get at least until they start using better hardware and upgrade version to true 4.2 or a 4.4
[Android Head-Units] gyaku_setsu:
Don't get the parrot. It works more as a whole for dumb users, but the minute you think about any kind of customization, it is so bogged down with proprietary limitations and SUCH a long boot time that it is more trouble than it is worth. And, like you said, the processor sucks. I have never been impressed with the smart's performance and it takes a painfully long time to respond to any non-proprietary apps. Plus it is running something like android 2.2, which omits basically half of any good apps you might want to install.

Don't get me wrong, I made it work for me and was happy enough with it until mine died, but I would never get one again.
[Android Head-Units] Ackms421:

I installed version 2.8.3 and I can say it is OK.

I'm having the DVD version, I had not the courage to test the "full format" so I just root up to restart, but it is enough to replace the file "com.tw.service_a5a4" and install "Viper for android" (which works fine even after restart).

It has some new settings, video player has 2 good changes, a button "FullScreen" and playlist is move to the track wich is running.

In short, worth trying.
