Hello,

I'm a new member on this forum. I've bought this unit for my Ford Focus.

Everything is working well (GPS, WIFI dongle, and apps like spotify, etc...) but 3G dongle does not work.

I bought a 3G dongle which is compatible (Huawei E261). When I plug it, I have little bar graph on the top right of the screen but no internet connection.

Of course, I've added the access point of me carrier (SFR in France) but no success...

3G dongle is working well on my laptop if I create a connection with dialup number *99#. But I don't have the possibility to set up a dialup number in android menu...

Does someone have a procedure to make working the 3G dongle ???

Thank you

Thomas

In the Extra Settings there is an option "Switch SD Card" What this does is swaps the "sdcard" directory with the "extSD" directory. So when I have it set, my microSD card is showing up in the "sdcard" directory and my internal storage showing up as "extSD". Poweramp, N7 Player, etc... sees and plays all my music no problem.
[Android Head-Units] gpmg762:
Make sure you plugged in the 3g dongle before you power up the unit. 3g dongle not plug and play like WiFi dongle.
[Android Head-Units] TTpowa:
Thanks for your reply

That what I do, always plug the 3g dongle before powering un the unit.

The dongle seems to be well recognized by the system because I have signal strength on the top of the screen.

My unit is not rooted, is it necessary ?

In access point parameters, I have access to APN (sl2sfr), MCC (208), MNC (10) and APN Type (default) paraemeter but not dialup number...

My head unit arrived yesterday - purchased on Aliexpress from a high feedback seller. When I unboxed it I noticed a rattling sound so I undid two screws and opened the bottom plate (warranty sticker was on the top) just enough to get the foreign body out. Low and behold it was a small screw - never a good sign!

Anyway it powered up OK using an ATX PSU. Unfortunately it wouldn't play DVDs or CDs - sometimes the loading screen would come up sometimes not. Eventually I did get it to play one DVD and one CD - both were 100% pristine. So it seems it cannot play discs with even very minor surface scratching which all play fine in my other CD/DVD players including my 10 year old Alpine head unit. I'm guessing misaligned laser or dirty lens.

The iPod input didn't work either : ( Tried it with a 3rd generation nano and an iPhone 4. When I switch to ipod mode I just got a grey screen with spinning circle, a brief burst of music then silence and back to the home screen. No sign of the ipod\iphone charging either. Noticed that there was a small bit of plastic chipped of the iPod connector but didn't look to be affecting the connection. Just in case I tried another din to iPod cable I had for my existing head unit but it didn't help.

When I contacted the seller he said the DVD drive was tested and worked well before it was shipped. Also said that head unit doesn't charge an ipod/iPhone but might do if they were routed (I presume he meant jailbroken). Told him I would send him a video of both problems tonight.

I'm in two minds as to whether or not to press for a return as I rarely if ever use DVDs/CDs anymore and if it doesn't charge iPod/iphones it kind of defeats the purpose of leaving my Nano connected. I had hoped to do this as I think the iPod interface is better than the stock music player? I didn't mention the loose screw to the seller as he could claim I damaged the unit getting it out although I'd I'd left it in it could have caused a short. I guess I probably could tell him about the iPod cable - he could always send a new one but am sure it wouldn't help.

On the other hand I paid good money for an item that's faulty so maybe I should return it but it's a lot of hassle for features I'll probably never use!

Is poweramp the best music player option & is it possible to use the physical track skip buttons/steering wheel controls when using it?

Thanks
[Android Head-Units] PsychoMcSatan:
If you do decide to return it, my advice would be to put that loose screw back in and just tell your seller that you hear rattling.
[Android Head-Units] KID52:
I've just paid my customs charges on my new unit, so hopefully it will be turning up soon :)

I am interested to know how the hardware differs, since it claims Bluetooth OBDII compatibility out of the box, but I assume the software will be identical and work with the updates from this thread.

I have not been able to get a system update from the seller I purchased the unit from yet though.
[Android Head-Units] digitaldr:
Good idea although he might wonder why I didn't mention it before now.
[Android Head-Units] sciallo:
What did I miss? what happened to your original unit?

---------- Post added at 10:44 AM ---------- Previous post was at 10:43 AM ----------

because you didn't shake it before deciding to repack it for return
[Android Head-Units] KID52:
I sold it, posted a few pages back with a link to my eBay auction :)

Decided I wanted to try one of the 4.1 units with a 7" screen and no DVD player, plus it claims to support Bluetooth OBDII.

Not a very exciting upgrade, and perhaps not an upgrade at all, but I am just curious.

Factory

Hi guys

As in my post many weeks ago my unit failed and as I was visiting china (shenzen) I went to the factory where these units are made to return mine for a replacement.

They are advertised as located in Hong Kong, but that is the shipping port.

I had already emailed the manufacture weeks in advance to let them know I was local and bringing my unit in my hand luggage and he said great that will save on shipping.

When I arrived I called the guy and he pretended to have no knowledge of my emails and was very reluctant to let me come to their factory saying they were closed, flooding etc.

Luckily I had my associate with me from the company I was visiting and she called him (in Chinese) and finally he agreed to let me visit after many phone calls.

Above I said factory which is a very lose sense of the word.

It was basically 20-30 people in a very run down high rise building soldering this stuff together, no anti stat precautions (hence failures?), they were swapping bits from damaged units to other units and it was quite shocking to see how they work.

They must sell a load of these things as they had hundreds/thousands of units stacked floor to ceiling in this damp sticky/humid environment.

They took my faulty unit, removed all the covers and started sticking tape over the connectors to remedy the faulty touch screen which of course didn't work, eventually they gave me a new unit.

I asked about the unit they had offered me in the past supposedly an android 4.4 unit, he did show me but would not let me run any system diags to confirm so I suspect they are the same as we have now.

All in all i think the issues and quality we are seeing is due to the poor manufacturing line, it really was that bad!

They have however given me info and UK resale opportunities for all their units and believe me they are cheaper than we buy from, Ebay etc.

The AN-21 can be bought in single sample for £110 or $170 shipped!

Thats my five cents worth of input after physically being there.
[Android Head-Units] digitaldr:
Sorry but I'd like to give him a chance to sort it out first before giving the link on a public forum. In fairness to him he's been quick to get back to me.
[Android Head-Units] jpapadami:
Mind telling us from who you bought the unit from? Ebay, Aliexpress, etc... seller name?
[Android Head-Units] shavermcspud:
I purchased from Star_car_radio on ebay UK but I went direct to the manufacturer for replacement. company called SZelec

The new unit works fine, but I was keen to see what kit they had to offer with the hope of shipping a few back in my container with my other stuff, but I am not so sure after seeing the QC.

BTW its an amazing country, bargains galore !!
[Android Head-Units] j2gifted:
I had a problem with my DVD/CD drive when I received mine. They offered a partial refund or to pay to have the item repaired locally but bcuz its a no name unit no1 would touch it, so I returned it for an exchange. Had to pay $80+ for retuen shipping wirh USPS... got the new one and all is well except they forgot to resend a reverse camera. I just asked for partial refund for that. I kept my wiring harness to avoid re-wiring all over again.

I ordered from beststylegift on ebay...

I thought about just keeping thw forat one since I dont listen to cds or watch dvds in the car, but if I wanted one without the dvd thats what I would've ordered.

External SD

Can anyone verify this? I am not seeing it in my extras menu. I am still on 2.6.62 since there seems to be no benefit to upgrading, and many people have experience many issues with doing so. If i am able to gain this functionality I would consider updating. I am hoping that things like google music and spotify will cache their music files on the external SD.

Media player unable to see the external sd

Hi all, searching in internet I found a solution for media player that are unable to see the external sd, it's work on my AN -21 U single knob.

1- Download Rescan Media (I used the root version)

2- Download Media scanner

3- Go to Settings / Applications / All / Media Storage and clear data

4- Reboot

5- Open Rescan media and disable the media scanner

6- Now re-enable it

7- Now, open Media scanner and tap Start scanning

8- Voilá, now every player will recognize the music stored on both SD Cards.

I hope this could be helpful:)

upload mode

Can someone please make sure this gets post into all the right threads. The radio that does not have a menu button you have to hit the reset button (with a paperclip) and hold in the power button and that is how you get into "upload mode". I was searching for this everywhere because I was stuck in boot loop and everyone kept saying volume rocker and power button. That does not work with the Unbranded Android Radio with no menu button and 2 volume rockers (the volume knob is on the right). I also have all the MCU's and software update for this radio. I have bricked it at least 5 times now playing around. If you will help please direct me on where to put the files and stuff. I'm an IT Specialist with vast knowledge of Android Development and Microsoft Operating Systems. As I skim through your forms I can answer 99% of these questions. I just don't have the patients to reply to most of them. However, I finally took the time to register and maybe I can solve the worlds problems on here. lol. Below is a link to my you tube channel so you know i know what i'm talking about. lol. For any questions with your radio superbass311@gmail.com and I am here to help the Android Car Radio World!

All available update files that we know of are in linked in the OP (Original Post) AFAIK

Welcome to this mad thread :)

Let me start with the dreamiest question of them all... Are you able to figure out what type of encryption the update files are stored in? can you brake it?

---------- Post added at 10:13 AM ---------- Previous post was at 10:06 AM ----------

Nobody can remove the restriction, it will go away once you posted enough, for now, just mask links so they're not seen as links for example _www.google.com_ and make your "once in 5 minute opprotunity to reply" count :)
[Android Head-Units] superbass311:
I'm not sure what update files your talking about to really answer the question in depth. you talking about the firmware or the MCU? I know how to manipulate both. **** given enough time I'm pretty sure I can write my own interface but who the **** has time for that. I have not really been breaking anything so much as playing with different MCU files and different firmware. Example. My radio is not on the latest. MCU. instead its on a modified version of. 4.2.13.8-10 and my firmware is right out of a website from china. (a real china site; you need a proxy server to use the "real" internet, lol) . 128-bit AES. (Advanced Encryption Standards) I think is the answer to your question in a nutshell.

*Your not really an android professional unless your brick multiple devices multiple times. lol.

what are you trying to do? Remember your on the front of the technology wave. In 5 years everyone will have an android radio and you will be able to say I had that s**t five years ago. lol. (Like everything else I own) Being an IT specialist and Techno Geek is an EXPENSIVE Hobby. Depending on my upcoming schedule I'm going to purchase another android radio and leave it on my work bench. I have had my radio for about 6 months now and its installed in my Jeep already. So messing with it is a pain in the ass.(but doable) My windows tablet has helpled out a lot with a lil microSD card. Nothing like sitting in the driveway and smoking a bowl and bricking your radio. lol
[Android Head-Units] sciallo:
They both seem encrypted the same way But I'm mainly intereseted in the firmware.

LOL I must be on my way to "professional"... I'm on my third unit (bricked two different ones)

Leave alone stuff like custom rom and s**t that, as you put it "who has the time for it?"(btw, you'd be surprised, if you have it down, share pointers and some will have the time to run with it)... My main thought is that this unit, as opposed to others, for example the original OUKU, has a major disandvantage that all out finding and hacks can only be replicated, not incorporated in a update.

Take the OUKU, every little fix, mod and even some kernel modules we came up with ends up in a firmware update, it's at a point that you buy it, flash that firmware and it all works as good as we got it to work...

In our case the best we can do is save a bunch of files in a repository and make a list of things to do to make this and that better... Not trying to come up with our own ROM, that would be nice, but a bit too involved and would be hard without sources and complete understanding of MCU communication. Just merely being able to package our "hacks" in a modified ROM would be nice...

BTW what shows as your system and MCU versions under "About device" in settings with that chinese update?

power amp issues

I origanally installed power amp on my rooted an-21 2.7.9 & it was fine , finally some decent sound & widgets lol , ever since a power cycle , i now get no audio from power amp :/

Any suggestions ?

Many thanks

This has been mentioned many times in the thread. Please try using the search feature.

I believe the solution is to disconnect the battery, or press the reset button.

Also under Sounds, go to Sound Priority and set it to 3rd Party Applications

---------- Post added at 11:58 PM ---------- Previous post was at 11:49 PM ----------

My stereo came with firmware 2.6.70, so I don't remember if this setting is available. But with 2.6.96 and above I know it's there.I would just update to 2.7.9. I haven't had an issues with this firmware and all is good.

I personally haven't set this Switch Card feature because all my 3rd party music apps are able to load all songs from internal and external SD, but I have played around with this feature. I can confirm that when setting this feature and using ES File Explorer to browse through the folders and the "sd card" directory and "extSD" directory gets swapped.

I have the same firmware and I also use audio glow wallpaper. Have no problems. Why don't you go to Display and set Forced Landscape. Not sure if that will help, but I have that set and have no issues with saving wallpapers.

---------- Post added at 01:27 AM ---------- Previous post was at 01:25 AM ----------

Can anyone recommend a good external microphone for these units or a way to increase the mic sensitivity/volume through Android? I have an UltraDisk 4036 mic installed on my car, but the mic volume is just too low.
[Android Head-Units] Kn0ck0ff:
iv just given that a try , it didnt work , i think that refers to the landscape picture size , ie stretched , unlike a portrait . Thanks anyway , i must be missing something , it reverts back to the winter wallpaper everytime , i take it you go settings/display/livewallpapers/audioglow/set wallpaper ?

thats my course of action , downloaded both audio glow apks from google play , free & purchased ones , tried both together , individual , still no joy , iv even disable the bubbles , nexus pappers too , i dont know enough about rooting to make this a possible system app .

When I used the stock launcher from the home screen I would click on the menu hardware button, then wallpaper to set it, but I don't think it should make a difference how you set it. Never had a problem. Now I use Next Launcher 3D and everything works there as well.
[Android Head-Units] Kn0ck0ff:
Iv read all 300 & odd pages on this forum , some people have this issue some dont , it has to be something simple , everything else is fine with the unit bar this , there has to be some way of deleting the old wallpapers from there folders , then maybe pasting AG into those folders ect ect ect ... pass lol

ive even tried making it a system app with titanium backup , Just tried the Next launcher too , but still the same issue , it keeps reverting back to winter theme , yet again if nexus live wallpaper is selected it boots to that fine , running out of ideas now , somebodies got to have figured this out , god damn stupid winter wall paper .

https://www.youtube.com/watch?v=I3I2gjmGBuc&feature=gp-n-y

Just been on youtube & posted on one of peter chans videos , fingers crossed he replies :)

Is there any means of reverting these units back to complete factory settings ? i.e all downloaded apps , info , logs , caches cleared .

Thanks for the advice anyway :)

[Android Head-Units] jpapadami:
This has to be a software issue. There are really only 2 things that I can think of to help you out

1. Do a factory reset

2. Do what I did. Update from 2.6.70 to 2.6.96 > 2.7.4 > 2.7.9 and perform a factory reset.No need to root each firmware. Just the last one. I'm not sure if this will help but its worth a shot.
[Android Head-Units] Kn0ck0ff:
im on 2.7.9 now , with what your saying id downgrade to 2.6.96 , then carry on updating again , are upgrades ok even in a backward cycle ???
[Android Head-Units] jpapadami:
I don't think the unit does a firmware version verification. It just installs whatever is on the microSD card. I haven't found the need to do it, but have heard that other people in this thread have done it.

Backup camera style?

Not sure if this has been covered but I have not found a answer searching this thread or the wiki. Asking the chineese ebay seller doesnt help. They just keep letting me "kindly know that this unit need backup camera". :good:

My unit came without a backup camera. I have found a bunch of them on ebay/amazon/etc. Question is, do I want a mirrored/reversed image camera or a normal image camera?

It seems that some cameras flip the image before sending it to the screen to make it look like it would if you looked at your rearview mirror, where other cameras send a image as it is and the screen/headunit has the ability to flip it on the display.

which style cam are you guys running?

Also, are you running the cheaper CMOS cam (which i will probably get) or a CCD cam?

Thanks!
[Android Head-Units] jpapadami:
How do you brick a stereo by reseting it to factory defaults? It just doesn't seem possible. Try pressing the power button and the reset button with a paperclip. Some units use a different combination of buttons to get tho the firmware flash screen.

Also I read that B.Stromberg was having the same boot loop issue after factory reset like you in post #2100. Maybe you can message him and ask him how he flashed his firmware files, given that you both have the same unit.

Incomplete root attempt

Hi all,

Firstly let me thank those who contribute, and apologize in advance for my n00bness..

I received a unit the other day, running 2.7.9.

Of course I tried to root it and have run into issues.

After the first reboot after step 1 of rootmyan21u, the screen is black, but with outlines of icons. So if I run the app again from its outline I can't see what's happening (or see the keys on the keyboard when its on screen). So I run the AUX app again and exit and I can see icons again.

So I then run step 2 and reboot again, install superuser. This completes OK.

When I then run terminal emulator and try and su, I get 'permission denied'.

So the system is now running slowly, and I can't complete the process to delete the prop file.

I ran a dirty flash of 2.7.9 over itself and I dont have blank screens, but still runs slowly.

Can anyone recommend the best method to recover/complete the root process?

Thanks
