.

Well, that just means they use the same software so there's probably some partnership / agreement going on with Landu and Roadmaster and possibly the source manufacturer. But, I believe that the AN-21 is also re-distributed by several other vendors; including Peter Chan from Pumpkin Cool which is where you got it, right? So, it could be different hardware offered with the same software.

Anyways, if the hardware is the same, at least its not one of those cheap Chinese ELM327 clones that you see on eBay which sell for 5 to 10 dollars. However, I would still be hesitant to leave it plugged into the car for long periods. Most cars' ODB connector is not switched by the ignition and continues to supply power even while the car is off. This leaves a power concerns issues since the Bluetooth adapter is always on. I found this out when I had the Progressive Snapshot installed on my ODB port. If I didn't use the car for more than three days then the battery would be dead, requiring me to jump start it. Another issue with most chinese clones is that you do not need physical access to device in order to pair it over bluetooth. So, if the OBD2 port is bridged or has access ECU's control of the door locks, then someone can use their smartphone with the right software to get into your car without needing the keys.

I personally prefer USB to ODB2 cable to avoid both of these issues, but if I were to forced to use a Bluetooth ODB2 adapter then it would be the Scantool OBDlink MX. It has both a power saving feature and security mechanisms to address these concerns.

Not pure android?

i read someone posting in the other ouku thread that windows ce doesnt support cpus over 1ghz and screen res over 800x480.

After buying one of the ouku units anyways i came across higher specced units that STILL have windows ce:

eg - alibaba.com/product-gs/1499873736/Newsmy_2_Din_Car_Pad_Android.html

alibaba.com/product-gs/1173912669/Newsmy_TUN23A_2_Din_Android_4.html

Furthermore, the base music, disc, radio, and phone apps have a very very plain UI and clunky, much like all the wince apps ive seen.

Should this unit not be 'pure' android, that would explain why usb dev mode is locked down and the rest of the unit is pretty much unrootable, and updates are encrypted to hide the wince parts???

anyways, despite having said all that im very happy with the unit, does everything i need it to do, and the screen is better than expected.

It sucks that keyboard and music apps are unsupported according to the google play store, but i got around that installing apk.

pocketweather always crashes too, so ended up installing a random weather app.
[Android Head-Units] Defender666:
In my opinion they have plenty of CE Boards lying around and this is why they hide CE and run Android as EXE on top of CE so they can still sell the old devices with new Android.

Yes it is the same software then on the ALIBABA Link.

What I don't manage is to pair the device, I need to connect it manually. I don't know how to pair in the phone app. KID52 ??

May be your device can also connect the Lanu OBD ?

Yes on my Renault Trafic it does not power off if I close the car. It keeps red LED, when connected to the Android it is blue.

I will install Terminal and keep you updated on all findings.

Also I want to add that the screen does not flicker at all on android. However I have diagonal lines in DVB-T mode which suggest they only connected the DVB-T internaly to an analog AV In. So still the DVB-T is the only thing actually I don't really like about the unit.

no gps

Had the same issue with gps lost today after updating to ...2.6.68. Then I flashed ...2.6.60 and it helped to recover gps. You should try...it has to help

---------- Post added at 10:15 PM ---------- Previous post was at 10:04 PM ----------

You are not alone with mcu unknown problem.... I was the 1st owner of test head unit from Create and chinese sent me some steps to update mcu because thet time head unit had too many bugs....so after using their update (steps of mcu change) I hade the same **** as you (mcu unknown, dvd unknown, disc stopped)... unfortunately can say you I didn't managed to find outbhow to fix with programmer from chinese factory workers ... I can say their program engineer seems to be really slow.... Tjey just send me the whole main board to replace and now this works. So it's sad but I don't think they will help you too much. But I'm sure with programmer it os possible to alive the unit ...but how?

What noticeable differences are there in 2.6.68? I really see no reason to update...

---------- Post added at 04:51 PM ---------- Previous post was at 04:46 PM ----------

I have only been able to get google search to work through NovaLauncher. It can perform basic functions like initiating goole music to play an artist or initiating navigation (although I still have to press the screen to open the intended app).

It was all working fine until I installed Xposed framework and MinMinGuard and told it to filter all my apps... I noticed my google search stopped working, giving me the same error you are getting. So I made sure that MinMinGuard was set not to filter google search results. Now it is functioning as before.
[Android Head-Units] fcortes626:
what is the mounting point for the tf card for the navigation?

never mind found the app ad installed and now works fine.
[Android Head-Units] Black6spdZ:
I'm not sure if it was just anecdotal, but 2.6.62 wouldn't recognize USB flash drive whereas 2.6.68 would. I hate the launcher and passwords on 68 though.

GPS

Hello i used an app i think is called gps scanner the picture is of a blue wifi signal looking thing.
[Android Head-Units] nikko82:
I have modified the Phone app (from version 2.6.62) so the contact list is now sorted alphabetically.

To install it, rename the original file (just in case) and copy the new one to /system/app. Change the permissions to 644 and reboot.

I'm using Total Commander to do this, it will automatically remount the system partition as rw.

[Android Head-Units] fcortes626:
i am having problems with the gps too. it was working fine for a while and the the signal dropped low and then i had no signal at all. the gpst test app shows gps is on i even downloaded gps status and toolbox from the play store reset and downloaded agps data and still having problems. can some one running an older system version pull the configuration file from /etc/gps.conf and upload it to see if that is the problem.
[Android Head-Units] fcortes626:
then it might be the gps firmware. why not try replacing /system/bin/MStarGPS.bin with an older version?:confused:

I'm using APK-Multi-Tool to disassemble the apk-file. After disassembling you can edit the resources (xml-files etc) and the code (in smali, not java). There is a tutorial here: http://xdaforums.com/showthread.php?t=2193735

You can also decompile the code into java using dex2jar, smali2java (or the $1000 JEB) to better understand the code. But as far as I know you will have to edit the smali files to change the code. To figure out what code to put there I write the code I want into an android-project in eclipse, compile it and then disassemble it in APK-Multi-Tool.

After changing the code you can compile it back into to an apk using APK-Multi-Tool. (I chose to compile a system-app for the Phone-application, not sure what's the difference between the system and non-system choices)
[Android Head-Units] fcortes626:
anyone that can help. i am trying to install the sygic maps on to the tfcard because the maps along with the app got deleted. so if someone can pull th efiles and upload them so i can reinstall it. not sure if the files are located in /sdcard/Sygic/ or /mnt/asec/ or if you cant pull the files look for a file called settings.ini and pull that one and the sygic app or open the file and look for:

m_strSetMapPath=
m_strSetResourcePath=
m_strSetContentPath=

and tell me what the paths are set to. then from there i can look for the maps elsewhere. I would really appreciate it if some one can do that for me. if not ill have to send the unit back and get another onewhich would take a while. thanks in advanced :fingers-crossed:

Reflashed to 2.60-2 (complete)

GPS STILL Screwy...Urgh totally regret upgrading to 2.68 now. Something in the complete package screwed the GPS

I had to power on. Power off. Using GPS status to reset (sometimes even that didn't work)

Anyone had any luck with other versions?
[Android Head-Units] kmtk:
Tried searching, couldn't find the answer to this, where are we getting these updates? Does the manufacturer have a site?

fix for gps?

I was having the same problem with the gps after the update.

Started with 2.60 initially, and went to 2.68.

i simply installed google maps from the market and that seemed to have fixed it.

havent had time to test it out fully yet though.
[Android Head-Units] ev1966:
I own this radio for about a week now and i am especially busy trying to get tomtom working on it. Without luck till now. I managed to have the app working even the navigating demo from TT works. But: the unit refuses to have a GPS fix with TT running. With iGo and Sygic no problem getting a GPS fix. I am tempted to update the system to 2.6.68 but reading the last posts about losing GPS, I don't know if that is the right choice.... I have a question about updating: did the ones that updated from 60 or 62 to 68 do that with a rooted device? And did you do a factory reset on 2.6.60 before flashing to 68? Was the problem caused by a wrong 2.6.68 file from Mirror 1? Is mirror 2 okay?

---------- Post added at 03:33 PM ---------- Previous post was at 03:25 PM ----------

Hi,

Sygic is installed in the root of the internal SDcard as:

/mnt/sdcard/Sygic/

The sygic folder contains three subfolders:

Android

Maps

Res

and three files:

Sygic eng.pdf

Sygic-13.1.1 -full apk

version

==========================

the settings ini paths:

m_strSetMapPath=/../Maps

m_strSetResourcePath=/../Res

m_strSetContentPath=/../Maps

I hope this will help you.

More faceplate options

Same hardware new faceplate.

I've been looking for more inconspicuous faceplates and found this one:

http://www.ebay.com/itm/100-Pure-Android-4-2-Din-Car-GPS-Navigation-DVD-Radio-Capacitive-Screen-1080P-/151177501782?pt=US_Video_In_Dash_Units_w_GPS&hash=item2332e19c56

Unfortunately pumpkin_cool doesn't seem to have it. They only have a Cortex A8 with this faceplate.

We should make a petition for more faceplates for this same or even better hardware. :D

For me, the ideal was a 7" with less bling bling knobs, few and small hardware buttons. I have a old 7" with winCE 5 and the burglaries don't seem to like it which is very important too to me.

http://www.google.com/url?sa=t&rct=...=S5Jx_baGWdBQXqHLHTnyBw&bvm=bv.59026428,d.cWc does an awesome job as a phone/text message app. It runs along side of the stock app. The stock app is merely an interface to a non android (MCU) firmware application that controls the phone bluetooth. (just like a cheap standalone BT thingie you could buy at wallmart, Just built in) Therefore, the stock app is still neded to pair with the phone and handle the BT. But Tablet talk can run along side of it and be set to allow you to initiate and answer phonecalls. when receiving calls both apps pop up a dialog but the tablet talk one shows caller details from your contacts....

Also, awesome for text messaging, through the phone...

Only problem at this point on the AN-21 (I had it going all the way right on the ouku) is that there is no contacts app... that was next on my list of things to figure out before I hosed my unit... It shouldn't be impossible to get a contacts app/sync installed.

Yeah, I'm finding that out, I finally got a hold of someone through QQ (a chinese chat program) and last I heard about 4 days ago he was going to ask his engeneer about it... I am hoping I can buy a motherboard from them if nothing else (hopefully for not too much). I asked for a tech support email address or any email address and got nothing. I emailed allison@szcreat.com multiple times for a few days and never got a sign of life... Do you have a contact there? Do you still have your old board or did you return it?

I was thinking about trying to program it with a circuit programmer for the STM8.

But:

1 - I would have to solder 4 wires for the connection in some seriously tiny spots... 2 of them directly on the chip and I will have to find out more details (probably get help from friend that has a bit more knowledge on microprocessor programming)

2 - I am not sure the MCU files we have are in the same format to flash that way....

I guess it would be just a $20 gamble if nothing else can be done, the board is crapped anyway, so I might as well try... if point 2 above proves to be true, an option would be to hook up a good working board the same way to extract the MCU. But that becomes a bigger gamble as I would be messing with a good board...

This post has some very good links to a lot of information about that chip.

[Android Head-Units] fcortes626:
cool thanks.. i thought it was installed at /mnt/asec/ because i had seen a sygic folder there. in that folder there wsa another folder with lib files and an apk. wehn i clicked to install the apk it was the sygic apk but i want getting any luck getting it to work again and i uninstalled it and all those files got deleted (oops).I wonder why on the ebay listings it says the maps are on the tf card but i cant find any tf card on the unit. i emailed the seller i bought it from and he said it was in the dvd card slot. dont know what slot, only slot i see if for the sd card. Anyway i have been searching and might have found a way to re install it but didnt know where it was installed to. thanks.

steering wheel buttons

Hello to all, I have good news and I hope it to work at all like at me. To make the steering wheel buttons work in other programs you must:

1. exit from the radio interface with a long press on the "back" which is in the lower right corner

2. launch player that you like. that's all...

I have tested it on my VW model of AN-21 with "PowerAMP" , function with hard buttons on the face plate with steering wheel buttons and with right wheel.

Now a few observations:

1. RADIO app does not work as a multimedia application: when you run music in the audio player (same PowerAmp) or another multimedia application radio does not get paused, it will continue to run in the background. You can test this: run radio after launch poweramp go on desktop and see radio widget with steering wheel control or with hard buttons you can change frequency but you hear music from poweramp.

2. The same can be said about the built player, with one difference, when you run a multimedia application you hear the sound from the two programs. "back" button in the default music player does not close completely app as they do with radio app.

I read here that someone has knowledge in programming,would be very useful if somebody would be able to edit the radio an player app to ,ake it work in this mode: program works as a multimedia application: when you run music in audio player (same PowerAmp) radio(or built player) gets to pause and returns control audio player. Same for the reverse transition to radio program: gets pause audio player, giving control to the radio (or built player) . Multimedia buttons work in the application that is currently playing audio stream, including in the background. In that mode work radio and built player but only between them two.

Excuse me for the mistakes I do not know English well, I used google translate.

Same same but different?

Hi all. New with the android head unit. I bumped in to this site because of need to root my device. Now. Theres a lot of pages already in this thread and I've read quite a lot already but I'm still uncertain. This unit which I bought is also unlabeled "Pure android"... Is it only this one model we are talking about here?

Now my question is has anyone tried to root this unit? ebay item 151183690014?

Specs are quite similar and UI looks the same.. I will try but I' just wondering if someone has already some experience? :confused:
[Android Head-Units] atijasa:
OK... GPS IS FINALY WORKING!!!!

so... what i did is... i copied this file.. /system/bin/MStarGPS.bin from 2.6.62 (thx to nikko82), but that didn't fix the problem... so in the location settings I disabled everything except GPS (google location s...) ... after i deleted Google Maps and Google Earth... restarted the system... and Sygic started to work perfect.... i don't know witch of this three thing made it work again ...(guessing google staff?!?!)

mine works better too. had some problems but then used GPS status and toolbox made a route and it worked. i would have to try it more. i did the same steps as you only i didnt have gogle maps or google earth. so i am guessing it was the firmware and you have to disable and re enable the gps.
