So have you actually managed to get a 3G dongle to work with PPP widget? If so which one and where did you get it? Thanks

PPP Widget

I have ZTE 667 dongle 3g(Digi Mobile carrier in Romania) and work good with my AN 21.Satisfied?
[Android Head-Units] goolac:
I was able to get the unit working again... 2.7.4 then I put 2.7.9 then 2.7.11 on and the unit works fine. New radio App is like the one in 2.6.98 and requires you to DRAG your stations to the slots you want them saved. If you want to change the name Long Press the preset and you will be presented with a naming box. Also to scan for next station HOLD the advance or behind tuning buttons.

These photos are not mine. It's from a guy who bricked his device. It seems that the green module circuit board doesn't support SPP profile or even worse, the bluetooth profile was consciously broken by chinese developers. Personally I think it's a dirty marketing trick. Original MCU version was 4.1.0-1-10-2101. The guy got a new main circuit board instead the bricked one and MCU changed to 4.1.0-1-10-6101. In other words, was added the new bluetooth BC6 module. The person noted this BC6 module have a better sound quality. BTW, I assume that the old bluetooth module used a CSR BlueCore3 or BlueCore4 chip. I have attached some new photos from another guy with a different revision of this blue circuit board module. The same BC6 chip and this module will connect to any OBD2 bluetooth adapters too. Fortunately on the circuit board we can see its labeling GOC-I2U-705A. I'm sure that the GOC it's an abbreviation of Hong Kong company Goodocom Tech. Their software controls bluetooth modules in our device. I think this blue circuit board module used reference design of Goodocom or even produced by them. Check the link. You can ask your sellers about the module then desoldering old one and soldering this new module. And you will get working bluetooth OBD2. )

How did you get it to work?

Did you just plug in the 3g dongle, opened pppwiget and pressed connect or did you have to edit things, like apn in the mobile data settings?

Very curious to know since i am determaned to get it working, and now the only thing ppp wiget is doing is "dialing out" and then disconnects.
[Android Head-Units] Krkiss18:
I think a have the same 3g dongle, i bought it from eBay too. I have installed PPP but still cant get it to work. I also suspect it having something to do with the APN settings but i also cant save any APNs nor is there any showing.. How do you edit your APNs?

I know the post is old but i hope you can help me a little bit.

Thank you

I have been sent a new firmware that claims to be 4.2.2, the files appear to be different to the fake 4.2.2 versions linked to recently, however I haven't tested this one yet so it may also be a fake 4.2.2.

[Android Head-Units] PsychoMcSatan:
I checked with a system specs app which reports API level 16 which I believe means it's 4.1.

Weird that there was another 2.7.26 a week or so ago, but this one is slightly different as it has different file sizes and the radio app is the other style.

Hi Mate!

[Android Head-Units] tdt038:
Well guys, here's a little explanation about the firmware versions.There are two versions of the same firmware. The first version with the blue skin and launcher with four large widgets is the main. The second version with red skin and launcher with red icons is a modified version of the main firmware specially for Russian seller called "RedPower", which cooperates with the Chinese factory "Winca".
[Android Head-Units] Miwer:
Another simple way of checking the API level is to run this command in a terminal window:

getprop ro.build.version.sdk

...or just 'getprop' to get a lot of other properties also.

I'm running 2.7.11 (supposedly 4.2.2, an update I got from my seller, and the file was named "Android 4.2") - using getprop, I get the SDK version 16 (which is Android 4.1) ;)

It is probably easy for the developers to change the version string before building, to make it look like newer android version (cheap trick by the way), but the API level will always expose their act. This can probably be changed too, but I don't know if that's an easy task, since a lot of apps (and included system apps), that depend on a specific API level for certain methods might start to crash if the API level is not correct. I sincerely hope they don't start faking the API level also - that would be no better than fraud (but when has that ever held those chinese manufacturers back). :p

This is exactly why you cannot [always] trust the advertisements of a device stating the android version - you buy something labeled "Android 4.2" - and you MIGHT end up getting some fake sh*t running 4.1 instead (and the seller might not even be aware of this). *sigh*

Rooting

[MENTION=1915855]KID52[/MENTION]

Great guide at the beginning of this thread btw especially how to root, BUT one step that caught me out when i first got my unit was i didn't know i had to install su user which might confuse people that are not use to rooting these units. Im not sure if you are aware of this but when in slow mode if you open aux and close it again it brings the unit back to normal making it MUCH easier to finish off writing the command in the emulator without the keyboard keep blacking out.
[Android Head-Units] KID52:
Actually it's only since the newer firmware versions that you need to install Super User beforehand, previous versions did not require this step.

I have been meaning to update the guide and make a new video though.
[Android Head-Units] Skratchuk:
Oh right is that the same for the aux work around as well?
[Android Head-Units] KID52:
Opening the AUX app is step 3, so it should open automatically on reboot to avoid the issues with not being able to see icons/keyboard etc. Hence why it is part of the instructions.
[Android Head-Units] Skratchuk:
Maybe it varies from unit to unit but that never worked for me i found opening aux before step 10 worked for me.
[Android Head-Units] KID52:
It is extremely unlikely that it will vary from unit to unit. I can only assume it may vary for different versions of the firmware, however if you open it for step 3, and press the home button it should open on every reboot, hence it should appear when you reboot for step 9, so when you press home before doing step 10 all should be visible.

I think I noticed pressing the back button on the default music app in firmware version 2.7.11 meant it did not open when I rebooted the unit, but I can't be 100% without testing that again. Certainly on the older version of firmware I was running, pressing the back button still meant the app opened on reboot.
[Android Head-Units] Skratchuk:
Ah that's probably why I just exited out of aux not press home.
[Android Head-Units] PsychoMcSatan:
Not sure if you guys have tried Baidu Root which a user suggested a couple weeks ago. I've used it to successfully root the last few updates and it doesn't require rebooting so it's much easier and quicker.

Gala/SDVC solution for Huifei ?

Hello !

Over at the Huifei forum, a savy forum member has provided an APK that changes the volume of the system depending on the speed that is picked up by the navi's GPS system. Normally, this kind of function is done by counting a timer on the ODB port (for example on my car it is a block-wave of roughly 1hz per 1km) but I've yet to see a China RNS which really has this working -although I've seen several units who have a setting for this, it never seems to work or it can't be connected-.

Anyhow, user "Dark Alex" provided a nice software solution for this which he presents for free, and although he developed it for the Huifei, he speculates it would probably work on most native pure droid 4.x devices.

Does anyone of you AN21'er tested this already ? Any feedback ?

See : http://xdaforums.com/showthread.php?t=2660662&page=99, although it starts roughly at page 91 I think.

Got my resolution from Ebay/Seller

Well, got my resolution from ebay.. Seller furnished a US shipping address in california to return the unit to and once shipped out and Tracking number is verified they will send refund.

In the meanwhile I bought another one of these units so I wouldnt be without while waiting for this unit to be refunded. Ordered the exact same unit from a seller on Ebay: Funnyinthebox, unit came from lightinthebox company in tonghai china, same place the defective unit came from. This second unit is working tons better so far than the previous one I got from ebay seller: gooddealphoenix. The dvd player works, the setting to remain on after power is removed for 30 mins or an hr works, and amazingly enough my google play issue isnt as bad. While not playing continously 100% of the time, it does manage to make it to the next track about 60% of the time. Another 20% of the time the unit will just skip to the next available track on google play music, although not in order. The remaining 20% of the time, the unit will still give the "unable to play the track you requested" Error. Still having my issue with the steering wheel controls being random. I can almost accept that though, as seeing how the unit picks up signals for volume and the variance is not within the units control.

So far so good.
[Android Head-Units] Salami Slanger:
I second this!

Please let me know if you find out!! That is my only disappointment in this unit. I have tried several naming schemes and tags, it is strange the order in which music is displayed in the stock app. I received mine Monday and it's specs are almost the same as yours. I will post a pic link below, just because I haven't seen one like this in the thread yet. Remove the spaces, noob post. I picked it because of the full size usb port on the front and the two on the back. Fits my needs perfect. The second SD slot has a piece of foam shoved in it. I am not sure what is behind it, but the maps are all stored on the internal storage so maybe it is just a hole with no slot back there.

I almost didn't order it because several people in this thread have commented that the album art in the stock app was non functional. Mine works perfect. It shows whatever pic I embed in the tag instead of the briefcase/music note icon. Mine also had a PDF used manual on the internal storage, and it shows the ability to sort by artist/album/songs/playlists, but I have been unable to attain these results. Does anyone have an IPOD to usb adapter to see if the IPOD player would play that way? Is this even possible, I am not an Apple guy.

[Android Head-Units] kaween:
That would indeed of interest, and not only for this device. My S150's stock player shows some stuff perfectly, while it refuses to show other metadata that has the same specifications (size, code, type ....). My wife's "Medianav" (An LG-Build-for-Renault&co) navisystem does that too : showing some stuff while failing to do so with other files.

But when I use Rocketplayer (to name just one), ALL art is shown for each song. It drove me nuts.:silly:

What do you use to do the embedding ?

I just bought this unit last week and I have been reading page after page on here. Thanks to everyone for their hard work on this unit. I am having a problem with the DVD drive on my unit. It plays CDs fine but it won't work with DVDs. It just stays at the loading screen and never changes. Anyone have this problem and any suggestions for a fix.

I contacted the seller on Ebay and they asked me to do a reset (did nothing to fix problem), then they asked me to take it to a local repair facility and they would reimburse me ( no thanks) and now they told me that their supplier is upgrading to a new unit and if I am willing to wait 2 weeks they will send me the new unit and I can keep the one I have now as well. Obviously sounds to good to be true. Has anyone else had this proposal from one of these Chinese sellers and is it legit. I decided to try it out and I gave the seller a deadline for delivery that is still within my Ebay 30 day protection so we will see what happens.
[Android Head-Units] kaween:
I've never known a reseller wavering the return of goods, at least not unless we're talking about sub 10USD parts. It feels unlikely, but not impossible.

As for the dud unit, it probably has a defective DVD-pickup. DVD drives generally have a dual pickup system at some level, one for CD, one for DVD as their repsonse frequency/reflective properties are different. That explains why it still plays CD's but not DVD's. Try a Factory-Pressed orignal DVD if you haven't done that yet to exclude readability issues which can occur with combinations of soms DVD readers and certains DVD-R/+R brands.

A better electronics shop will be able to replace the DVD pickup without too much problems providing they can find a matching part no. It's not any more difficult than changing the BD-pickup of a defective PS3 for example.

I use Tagscanner. (xdlab. ru/en/). I have tried a few others over the years, but I liked it's simplicity, layout, and amazon/discogs integration. It being free is also great although I found it so useful, I have kicked them a few bucks through the donate link. The music renamer is also real handy after you figure our a naming scheme you like.
[Android Head-Units] wizzuh:
I had that exact same issue with the dvd drive not functioning. I ended up returning my unit for a refund. Bought another unit from a different seller on ebay which doesnt have this issue. When i contacted the first seller about the unit not being able to play dvd's the seller reccomended that i take the unit somewhere for repair. That wasnt a solution I was interested in so I opened a dispute on ebay and the return process for a refund ensued. If you decide to return your unit, make sure the seller furnishes a U.S. address. And youll be refunded as soon as you submit a tracking number.

Id try and hold out the two weeks though, especially if you will still be in the ebay resolution time frame. You cant beat two stereos for the price of one. Worst case scenario, you open a dispute when your two week deadline expires and ship the unit to california for a prompt refund, and then buy another one hopefully with no issues. Unfortunately for me, i didnt get the offer to get a free unit. Id pull their card if I was you.

While youre at it, check ALL functions of the unit, I had my defective unit for almost two weeks before it was replaced and I found more and more things wrong with the stereo. The time delay off function didnt work on the previous unit, id set it for one hr or 30 mins, and as soon as the key was removed the unit would boot from scratch on next startup, Regardless if it was 2 minutes later or 20 minutes later. Also my screen had a less than stellar color, kinda hard to explain but the colors were muted. On my new unit, the colors are more vibrant. Boot time seems shorter as well.

You might find other stuff wrong with the unit, but if the two weeks thing pans out who cares. Good luck.
[Android Head-Units] bigblue206:
I haven't had any other issues other than the ones detailed In the thread. I am gonna see what happens with the seller and I will report back. I have had some of these Chinese sellers let me keep things before and still send me the replacement but never something his expensive. The most I have gotten was a $40 Ipod clone that didn't work well and then a second one that only slightly worked better.

Just tried it but it didn't work.

It seems that the command to change the volume is diffent on our devices.

Spped recognition wokr perfectly but it simply doesn't change the volume...
[Android Head-Units] kaween:
I suspected as much. The way the app works is by addressing the MCU directly. The Huifei has a different brand of MCU chip (Microntek, the AN uses an STM chip). The author said it might be not that hard to get it to work with the AN21 : if an AN21 user would be interested, it might be a good idea to get in touch with him. ("Nee heb je, ja kun je krijgen" - untranslatable dutch saying ;) )
[Android Head-Units] :
any idea how we can get the commands (volume up/down etc) of our MCU?
[Android Head-Units] kaween:
I could be mistaken, but I believe to have understood that on the Huifei forum, they captured the values that are triggered by the irremote.

But your should really talk to Dark Alex about this : he's very knowledgable, and from what I read he's real friendly and helpful.

I don't have a Huifei nor AN21 myself, but I'm interested in both of them and I think both units are very fine devices.

The Huifei is somewhat more powerful, but the AN21 is available with a Front Panel which physically fits my dashboard perfectly, the others are all a couple of millimeters too big. And the AN21 has a better RDS support (inclusive Radio Text, which is pretty unique when it comes to Android headunits, and I really like that feature).

The SDVC/Gala function is the only thing I'd miss a bit on the AN21-U. If that would be possible I'd order an AN21 in a heartbeat (also because I have been offered an AN21 for a fairly low price recently .. :) )
