[Android Head-Units] xxmessxx:
I lost all the apps and settings the first week I started using the unit because the power button got stuck and it went back to factory settings.... Is there anyway I can get all the options it had before? Like I want my music to keep playing when my reverse camera turns on but the options for that are no longer available. Or to change the radio interface...

I posted a picture because I have owned this unit for a while but have no idea what it is.

Root checker says it's rooted but I read that system version 2.7.32 can't be rooted?
[Android Head-Units] Chrisseh:
Hey folks.

Apologies if this is the wrong place to ask but I'm completely new to Android.

I purchased an integrated vehicle specific android stereo from Aliexpress called Pure-Android-OPEL-ASTRA-J-Car-DVD-Navigation-with-GPS-Canbus-Radio-BT-IPOD-USB-SD (can't post a link)

How would I go about finding out if it can be rooted etc? Or can all units be rooted?

Thanks!

[Android Head-Units] kaween:
Good evening.

Are you talking about this one ? http://www.aliexpress.com/item/Pure...-GPS-Navigation-Radio-IPOD-USB/680652232.html

If so, it's not an AN/Tonghai design. The screenshots don't provide enough info to let me speculate about its inards, but the screens themselves are nothing I've ever seen, neither on AN21, but also not on Huifei&Co.

Are all units rootable ? No. Yes. Maybe. :) Theoretically yes. But some are easier to root than others. Some come rootable out-of-the-box (like the Newsmy devices). Some are easy to root using a piece of software (Framaroot, Baidu) which is basically an idiot-proof situation (it either works or it doesn't, danger to you device trying to root is minimal). Some prove to be practically unrootable or require quite a bit of background knowledge to perform, often these methods are .... not entirely without risk. And then you've got the devices that are unrootable because no-one has found out how to do it yet.

Anyhow : The cpu frequency is a bit odd. At 1.2Ghz, it's not a Rockchip I'm sure. It COULD be a Cedric based one (like the AN21) as I know there were 1.2Ghz Cedrics "little M's" in the pipeline. If so, it should/could be possible to root it using some Baidu version. There's not much that can go wrong using Baidu, though you risk infecting your unit with some chinese crapware ..... but that's the nature of the beast. It also could turn out to be a Telechips or even MTK design as they too exist in 1.2Ghz.

Till we see the config/system overview of that thing, nothing's sure.

It looks like a very nice piece of kit for a dedicated looks-as-factory-fitted kind of install, but I can't say anything concrete about it I'm afraid, but it's bound to pop-up on XDA sooner or later.

I hope you'll enjoy your unit, and find the answers you're looking for soon. In the mean time, feel free to ask whatever you want, we'll try to answer as good as we can. :)

You could upgrade to a 2.8.6, 2.8.7 or 2.8.8 which should be rootable (at least, it worked for me), and that upgrade should restore most if not all the things you're missing now.
[Android Head-Units] Chrisseh:
Thanks for your prompt reply!

My unit looks the same as the one you linked yes. If you search for "Astra J" on Aliexpress mine is the first unit listed with the green Android logo onscreen.

I've managed to find another thread on here about the unit however it didn't contain much information other that the chip seems to be a quad core Freescale i.MX6 Cortex A9. Not sure if this helps any..

I've taken a few photos of various information screens on the unit incase those are of any use.

Thanks again for your help!

[Android Head-Units] chris.r.r:
Hey guys,

currently I'm using Sygic 14.7.4 which raises some issues with the focus of the media key hard buttons (prev/next track).

Previously, I was able to control Poweramp tracks when the navigation app ran in foreground (in case that the radio app was closed). However, with the newer version of Sygic this does not work any more, since nothing is happening when I press one of the media hard buttons. I assume, that the current version of Sygic is also registered as media key event receiver.

If the Sygic app is in the foreground and I drag down the status bar, the focus is working correct again (Poweramp switches to the next song) though. If I'm using the radio or built-in music app, the focus is also working (Radio switches station, built-in music player switches to next song). I could imagine that the built-in apps are handled more on MCU side.

BTW, it seems that it is not an AN21-U related problem because I read from a guy with a Alpine unit, who has the same problem.

Does anyone have a suggestion how to get the media buttons working again for Sygic in combination with Poweramp in background? I would appreciate any help :)

Has anyone bought one of these Rungrace 7" Android 4.2 radios? http://www.lightinthebox.com/androi...fi-gps-rds-ipod-bt-touch-screen_p2284399.html

Since my seller could not get me the MCU firmware and the radio was pretty much dead.. I shipped it back. Now I'm looking for another 7" radio.
[Android Head-Units] kaween:
Ehm. Based upon appearance and specs (MST GPS : well yeah, the GPS chip sits on the Cedric MST ARM cpu board) and the design of the apps (radio, BT, ....) that thing is an AN21 clone too.

Basically, I guess it is the same type of unit : maybe the bezel is somewhat different, but I'm quite sure the stuff that makes it tick inside is a AN21 design. Meaning, also with a fake 4.2 :)
[Android Head-Units] Netconn:
Since it's not a Rockchip I don't think it's 4.2 either. But it does seems to have a different system version then the Ouku I just returned. You can't get much info from the sellers, they answer basic questions but not the important questions. I'd like to get a radio with 4.2 or 4.4 but the ones I find don't have a lot of features or get too expensive. After all it's just a car radio.
[Android Head-Units] kaween:
It may look different from what your used to, but it is a 1:1 deadringer of my AN21-U in terms of app appearance when it runs 2.8.8.

So I'm quite sure it's a AN21. If so, it's 4.1, not 4.2 (well, it's a fake 4.2 with 4.1 code)

To exclude the dramatic turn of events you had with your previous unit, you may consider to ask "can you provide me with a download version of the system and mcu" upfront. On the other hand, if things ever go south (again :angel: ), they might find this question suspicious. On the other hand, in my experience, for the life of it these Chinese sellers can't remember their customers by name if their life would depend on it. :D
[Android Head-Units] Netconn:
Haha.. When I asked why they say it's 2GHz the response was "cause it is dule core.1G+1G =2G .1G means the one of it." Humm ok. I asked about the MCU and system download and I got this "you can download or updated anything you want derectly with internet". Also the CAN bus question was pretty fuzzy, too. He said I had to buy an adaptor for $25 that just plugs into the cable bunch but the pic of the radio cable and the pic of the setup he shows is very different. He didn't give me much info that I wanted to know. I asked if I could get the manual online "We have the use manual book of our products. It will come with our item and be send to you." So I guess you buy it and take your chances. That was these guys: http://www.alibaba.com/product-detail/android-4-2-2-din-car_60122494139.html

Poweramp Toast + AN21U : works !

Hi guys.

If there's one thing I was jealous about on the Huifei which we don't have on the AN21-U, it was the PowerAmp Toast APK made by agentdr8.

Sadly, it didn't work on the AN21 due to the differences in android versions between the Huifei units and ours.

Long story short : I contacted agentdr8 with the question if he would consider to rebuild a version that would run on Android 4.1

Within an hour, he produced a working version of it. I've tested it and it seems rock-solid : for those who don't know : this little program produces a small post-stamp like visualisation of the Track info inclusive cover art which will be visable on top of the active window (like for example a Navi program), providing you with feedback of the current track of your Poweramp while navigating using Igo (for example).

I think it's nothing short of brilliant, and I've donated agentdr8 for his effort. I call upon all AN21-U users who want to use this program to do the same.

A nice guy like him does deserves it !

The apk can be downloaded from here
[Android Head-Units] Zaphod-Beeblebrox:
Not to diminish his contribution, as I always want to encourage development, but I've been using this one for a while:

https://play.google.com/store/apps/details?id=com.domloge.mpopup

It works with more than just PowerAmp. Although It does have some issues with the Album art if the media hasn't already been cataloged by the media server in Android. Since many of the AN-21u users use PowerAmp for the very specific reason that the SDCard is usually not 'visible' to the media service, this may be an issue.
[Android Head-Units] kaween:
Hail my Emporer ! :)

I've tried that one too.

Issues I had with that one : all of a sudden, it wouldn't display ANTYHING anymore (not just missing Art, simply nothing). Reinstalling it made it work for a while, then it would again simply disappear without a trace. Guess its improbability engines sometimes fired up. :)

Also, I like the way Toast gives you control about the appearance and location of the poststamp : options that are missing in Music Popup.

Not the same problem as you're refering to but still PA related , I've seen several people also complaining about Poweramp not finding their USB or SD cards or the music that resides on it. As for the Poweramp not finding music ... I wonder if this isn't connected to Poweramp's less-then-clean UI. A couple of weeks ago, I started using Poweramp again and I too didn't find my music on the SD card, only the internal memory which I found odd, as it had worked in the past.

Pressed Settings, turns out Poweramp simply doesn't check the SDcard box where my music resides by default. Ticked the settings in the location box and voila, SDcard works. Not saying this is the issue everyone is having with poweramp, but I wouldn't be surprised a substantial part of the Poweramp users with problems get stung by PA's UI.
[Android Head-Units] wanxu:
Which skin do you use with PowerAmp?
[Android Head-Units] kaween:
Heh. If you next line is "yeah but Poweramp's Skin is totaly useless for cars" then I can only agree.

I leave the default skin working (with its far too small and ilogically placed navigation buttons, far to small text ect ect) as I feel they all are junk. In my ideal world, Poweramp would have a rocketplayer skin. :D (Big, clear text, easy navigation).

But as I can navigate through Poweramp using my SWC, I can live with it. Barely. :p
[Android Head-Units] wanxu:
Hehe, yeah, I totally agree!

I have a rungrace unit direct from rungrace (via aliexpress), but not with that faceplate. I have the two knobs version.
[Android Head-Units] tylerzipz:
Fun

Thanks, Sam. I was able to root after I read your comment knowing this was the correct unit. The upgrade and root worked but unfortunately my zone sound problem still exists.

Has anyone heard of the sound being completely crap in 2/4 speakers? I got it professionally installed and he said it was the hardware. Could a different MCU help me or is this unit just bad? Here is my first Post:

Im also having a problem when the ZONE is in the middle, the front two speakers hiss really bad, the only solution I found was to move the zone settings all the way to the back, does anyone else have this problem? (thats why I want to update mcu, thinking it might fix it)
[Android Head-Units] Spretti:
In my case did matter where i played the music from, internal,SD, USB. The scratch was there. Only thing that worked is Poweramp and i have 250ms buffering of the music. Now it works great.
[Android Head-Units] Netconn:
So, what do you think of the radio? Does it have a CAN bus decoder, 4.1 or 4.2, etc??
[Android Head-Units] superbass311:
I have had this radio for over a year. It tethers fine to my phone and plays Pandora, iHeartRadio, Spotify, and Slacker Radio. I also have Google Maps installed, and YouTube for when I'm sittin my my car with nothing to do. What else is everyone trying to do on there car radio? In my experience your not going to be Facebooking on it you have a phone and that is more practical. I also have a weather radar app to see the rain around me if need be. Mixed with Smart Launcher it makes a very good radio. All this without rooting it.
[Android Head-Units] RickyLan:
Hi Sam,

I have the same problem after I upgraded to 2.8.8 (from 2.6.70), I can only found 2 solutions for it (I use Sygic):

1. use TTS (so the APP read out direction through Android core, this way music and voice will mix together)

2. Set Nav Button to other app (such as browser, so that it will mute music and read out directions)

the best is to get TTS working, 2nd soultion you loose the hardware Nav key and the Nav Icon function on the desktop, as well as having music in the background with Nav speaking at the same time.

I'm going to try 2.8.10 or other lower version :(

factory reset and now can't download from the internet

I did a factory reset and now the unit won't find anything or download anything and says sSDcard not mounted. What to do..
[Android Head-Units] Netconn:
I've been searching around and I found something different. What do you think of this one: http://www.aliexpress.com/store/pro...d-4-4-Car-DVD-Player/1260460_32259071101.html

Says Rockchip 3066 4.4 android. Looks like the OuKu I just returned but with a different CPU and newer system.
[Android Head-Units] kaween:
iKGL made, so it's a Huifei&Co design.

There's at least one forum member who owns both (AN21 and Huifei) and the gist of his experience was something like :

1) much faster than the AN21's are, newer android versions available.

2) sound quality compared to the AN21's is -and I quote- crap.

Don't have any personal experience with these units myself, but it would stand to reason that the greater part of the info you'll find on the Huifei thread will translate 1:1 to the unit you've refered to.

---------- Post added at 10:21 AM ---------- Previous post was at 10:17 AM ----------

Exactly what unit and firmware version ?
[Android Head-Units] Netconn:
Well, it certainly looks like a bit better radio all and all. And does cost a bit more, too. I've gained a lot of knowledge from this forum, the web and lot of research. It's nearly impossible to communicate with these chinese sellers but I think I found enough info for now. Many thanks (so far) to you, Kaween..
[Android Head-Units] kaween:
No problem. I've learned a lot on XDA too, still do. And of all the forums I'm subscribed to, this is one of the friendliest and most-to-the-point. At least here, when people do not know something for sure, they say so. You've no idea how much time I've lost personally in search of answers by following so-called experts who's "facts" turned out to be very colored opinions at best.

Anyhow, good luck and much fun with whatever option you choose, and drop by anytime ! :highfive:

MCU help wanted

Hi

I have a silver AN-21 that originally came with system 2.7.9 and MCU 4.2.15.2-1-10-2101.

It also came with the Landu Bluetooth OBDII option. I have upgraded to System 2.8.8TT but am worried about the MCU.

I did not have that particular MCU in my /etc/MCU folder and I cant find it anywhere.

I do have a Titanium backup of my 2.7.9 but I don't know if that would backup the MCU. Is there any way of backing up my MCU? Can anyone please send me a copy if they have one? Does anyone know which MCU is best with this combination of 2.8.8TT? Everything works but I have to pair the OBDII every time I want to use it and after 2.8.8 the text is wrong in Bluetooth pairing.Thanks for all the great help.

I am having an issue with my unit where the radio aapp will work fine for about 2-3 minutes, then it goes out to static (kindof like the antenna gets unplugged). I can switch apps to pandora / Internet radio of any kind and the sound will come out of that fine. Switch back to radio and it is static.

I can restart my jeep and the radio will work fine again, for 2-3 minutes...

Any suggestions?

The Radio I have is this amazon.com/Pupug-Android-Navigation-Vehicle-Mirroring/dp/B00NXMYNIM/ref=cm_cd_al_qh_dp_t

Pupug Android 4.2 Car Radio

So you have to have power am install for this to work ?? I could only get PowerampToast_v1.4.3 and PowerampToast_v1.4.4 the rest fail
[Android Head-Units] kaween:
Poweramp Toast works together with PowerAMP. So yeah, you must have a version of Poweramp installed to make it work. The toast is "JUST" an external visualisation routine, not a mediaplayer.

I thought that was pretty obvious, the latest when I wrote that Toast gets the track info offered by PowerAmp itself. :)

Anyhow, Versions prior to 1.4.3 do not work on the AN21 as they were compiled for Android 4.2 as minimum os version.

As ALL AN21's are running 4.1 no matter what it says in the system overview, you'd get a parser error when trying to launch them.

Google maps

I love head unit, i have been using it for some time.

A couple things... I wish there was a section on this site for these devices. It would be easier to find solutions to problems instead of navigating through almost 700 pages of information.

[MENTION=2209084]cberg[/MENTION] :

In the mean time, I did some background searching on that Landu OBD. It turns out it's indeed "altered" so it gets the ability to communicate with a device over the BT board (which in terms of system resides "outside" the android system, which is why we have to pair BT using the dialer and not the standard Android BT method) and somehow inject this info back in the android part of the system. If I understand it somewhat, this only works with their own specific software (B-scan ?) and not with run-of-the-mil things like Torque&co.

So yeah, it's not totally improbable your mcu was altered by the seller to accomodate this feature. Still awaiting answer on the BC6 module, seller misunderstood me and thought I was looking for a complete mainboard instead. :)

[MENTION=5024097]uziele[/MENTION] : I've not encountered 8din firmwares here so far and yes, sadly, those are different firms (screen res different, touchcontroller probably too). I'd contact my seller, if he's a bit helpfull he should be able to provide you with what you need.

[MENTION=6328837]psylentl3lue[/MENTION] : not looking to add insult to injury, but i'd try to find an older Google maps version and install that back. Will probably be the easiest solution. Or try a different piece of free nav software : I was pretty much charmed by what "Here" offers (though still in beta, the ability to work with offline maps in a propper manner is nice).

That was it! I ended up changing it and instead of resetting, I just factory reset again to be sure. Worked like a charm. I am once again very happy. Also for those struggling with maps force closing, I went to a site called apkmirror and they have older APK files for lots of programs. 9.0 maps for 4.1+ works great. Turn off auto update. Maybe the next update will work on our systems.

Kaween, I really like how my deck is working now. The only thing I'd like to work that isn't is torque via bluetooth. I'm curious if updating the firmware is worth it.

apkmirror, download maps version 9.0.0 (The first one after any version 8.0) for 4.1+. Turn off auto update in the play store, you should be good.
