I bought a headunit made by Infidini and it seems to be the same as the Tonghai

Quad-core 4 x 1.6GHZ

DUAL Mali 400 x 400MHZ.

Display 9"

Radio TEF662X

Resolution 1024*600

MCU: 5.3.18-62-61-940201-151120

System Version: 4.5.9_20160322.

Android: 4.4.2.

I post yesterday on that thread, to explain my issue. (My questions are maybe better located here :o.)

I have sound in every applications, excepted the radio. I can store stations and their names are displayed, but the radio is still silent with no background noise.

In Extra setting I have access to the radio region, but not to the radio chip type. Does somebody know where we can found this setting (hidden menu ...etc)?

I didn't find neither a setting to set the sound individually, I mean between GPS, handsfree, music ...etc? any idea where we can do that?

Any answers or tips would be really appreciated

That's great news about the root. Could the 2 of you please point me in the right direction with Kingroot? Which version did you use, is there an English version, anything to consider? I'm only aware of a Chinese and a Russian version, 4.0.6 found at 4pda.
[Android Head-Units] vdsem:
I used 4.0.5 found at 4pda .
[Android Head-Units] sciallo:
I don't really remember, I googled it downloaded and use it while on the road, I was the passenger of course :)

Pretty sure I used the one from here: http://kingrootapk.com/kingroot/
[Android Head-Units] vdsem:
Who can upload the system folder , as shown in the video hellSunshine .

Is the firmware from Kaier .
[Android Head-Units] hellSunshine:
Quadcore Firmware (Kaier)

Did anyone succeed to get the firmware for the quad core R16 (Kaier firmware). I would urgently need it since my radio is stuck in the boot loop due to some faulty boot animation and I need to flash it. (Yes, I know did something very stupid but actually it was an accident). :crying:
[Android Head-Units] imableeblob:
Updated thread. My OBD should come in any day now. Lets see if this unit can use 3rd party OBD's at all.
[Android Head-Units] Hisma:
This statement seems confusing to me. "it is not any of these, however it is another hybrid of AN-21U". So does this mean that even though though it is not the specific model mentioned in the first post, it will still accept kingroot? I don't care so much for custom rom, I would just like to root so I can install xposed and get some extra control over the buttons, set poweramp to work w/ my SWC, etc.

My unit arrives next week, and I want to make sure I can apply kingroot w/o bricking the thing.
[Android Head-Units] imableeblob:
I'm sorry for the confusion. Your model has different specs than the ones listed in this thread. (Different hardware) However it is running the same software as these units. So as for ROMS your model would be incompatible. (There are no ROMS yet for these models anyway so not a big problem) However with the same software components I can infer that Kingroot would work. That is why your model confuses me. Its not in the same category as these units in this thread. Yet has the same software. Most likely more units like this will surface soon.

EDIT: After looking into your unit. Your mistaken, your unit is a identical match to the units above. Hardware and Software wise. I will update the front post.
[Android Head-Units] Hisma:
thank you for the clarification. It is good to know my unit will have some support on xda. I apologize for questioning the hardware, but the research I did on the R16 on google showed quad core A7, not A9.

Anyway, if you there is anything you want me to test for the benefit of others in this thread, hardware or software mods, let me know. I am not afraid to experiment :).
[Android Head-Units] Hisma:
i installed my head unit last night. Everything works great. I will ask that the OP please update the specs on first page. You state the resolution is only 800x480, but mine is the higher resolution 1024x600. Also, you can use external storage higher than 32GB as long as it is formatted as FAT32. I am currently using a 64GB flash card. There is a tool called fat32format that is easy to use and will format storage >32GB as FAT32 as you desire.

http://www.ridgecrop.demon.co.uk/index.htm?fat32format.htm

Going from carjoying UQ-124 to this unit is a massive improvement. The fact that it is built for my car model specifically is a big improvement, but also I feel performance is better than carjoying (which was also already very smooth). They both have quad core A9 processors, but the R16 is a newer model than RK3188, and I believe the R16 has access to L2 cache that RK3188 lacks. The improvement is noticeable. Also, the BT audio quality is MUCH better out of the box than the carjoying, which is straight garbage. This was a big concern of mine, and happily it looks like the chinese engineers did not fubar the BT audio on this unit.

SWC works by default with poweramp, so no need to install xposed modules to get this feature to work. I bought a BT OBDII module and am having problems pairing it, but I didn't mess around w/ it much and the seller seems to be willing to help me after messaging them about it last night.

The only thing I notice is that the stock ROM has even less customizability than the carjoying ROM, which has complaints of being stripped down. The settings page is very minimal, and accessing certain settings like audio, bluetooth, etc must be done from individual apps instead of through settings like standard android systems. I have a feeling putting a custom ROM on this unit would be a bad idea, especially since my unit is made for my car and has CANBUS & SWC all mapped to the right keys by default. I would like to see if I can root it though.

Overall, going from the carjoying universal unit to this newer AN-21U clone has been a great upgrade. It is better in every way, except for settings customization, and of course support here on xda. Hope more active users get this unit and support continues to grow.
[Android Head-Units] ADB100:
Is this one from the same source?

I have been busy reading and asking questions regarding Android Head Units and have come across this one for my car:

http://www.aliexpress.com/item/2014...600-IPS-Capacitive-Screen-Car/1802218812.html

It appears from the screenshot showing the 'About Device' that this 'might' be from the same source.

QuadCore-R16 1.6G
MCU 5.3.17-6-10-450101-150817
System 4.4.4_20150817
DVD 2.13.15-1200xh-150417

However we all know how easy it is to fake the images or for the sellers on AliExpress to just post incorrect images :(

My requirements are (were?) a KLD or KGL based MCU, a Quad Core RK3188 based SoM, 16GB ROM, 1GB RAM (I'd like more but can't see any devices with more than 1GB RAM?), a 1024*600 screen, CANBUS (obviously Bluetooth, Wifi, USB, SD-slots etc).

Is it likely we will get some custom ROMs for this or will we be waiting for a while?

Andy
[Android Head-Units] Hisma:
Yes this appears to be the right model. Same hardware and same ROM as noted in first post. Note that the CPU is not RK3188, it is a allwinner R16. Different CPU but similar specs. R16 is better than RK3188 (I have used both and can confirm). Read my quick summary review above to get an idea what to expect. I do not know what MCU it uses unfortunately. This is totally different hardware from previous gen AN-21U, so it will be a while until we get custom ROMs. We need a dev with this specific model to get on board.
[Android Head-Units] imableeblob:
Yes it is identical. Ive added it to the front page aswell. And we have confirmed a root for these units in the first post.

As for ROMS, these units are very new so we are the first venturing into new territory. Who knows how long until something is released.
[Android Head-Units] Hisma:
I'm experiencing some minor annoyances with my unit, if anyone else has a solution.

* phone does not auto-pair when the unit turns on from boot. I have to manually pair it every time, even though the unit recognizes my phone.

* I can't figure out how to re-map my keys. I go to the key mapping page, and it doesn't seem to recognize any of my responses. I think this has to do w/ my keys being set by canbus instead of using the resistive keys? (key 1 & key 2)

* the EQ sucks. Don't think there is an easy solution for this, other than it is disappointing to say the least. I have had a rough time trying to get decent sound out of my aftermarket speakers. I am getting a sub & amp later this week. I'm worried I still won't be happy w/ the sound despite spending a decent amount of money on aftermarket parts. All these chinese HUs seem to have this problem

Also, is there something similar to car service app that allows some additional control of these units? I'd like to auto-launch poweramp on start-up & tweak some other things.
[Android Head-Units] kenfly:
I bought one of these, and I am having some issues where I cannot sign into my Google account anymore after a FR. Just says cannot connect to Google servers, try again later.

Also, has anyone fixed the constant google play services error?

I'll try contacting my seller for the FW
[Android Head-Units] Hisma:
I do not have either of these problems. I think others have said that you don't want to update google services to newest version, just stick to a base version. I have had no issues w/ errors. I can voice search, check google now, etc without any issues.
[Android Head-Units] kenfly:
Youtube/google music do not run without the latest
[Android Head-Units] imableeblob:
If I remember correctly, I had to get the apk of I think google services because the device didn't have anything installed. Otherwise after that it worked.
[Android Head-Units] kenfly:
Here is the link I was given by my seller for the system zip.

problem with signed play store app

I have the model in the top left picture. The version of play store installed on mine has a conflicting signature and will not allow me to install updated play store. It also will not allow me to connect to the play store or login despite it being connected to a T-Mobile hotspot at 4G with full bar strength. Any help?
[Android Head-Units] Remiguel:
Today I've realized that when the radio application is chosen, I have no sound, even in the GPS app. As soon as I switch to the music application, the GPS app start again to play as it does.

With this short test I can say that it is not a hardware issue neither a bad radio chip setting. It is more a software problem.

I don't use the direct speaker lines. In my case the external amplifier line feeds a SPDIF converter to input a digital signal to the Infinity/KIA amplifier. I've already tried to attach a speaker to the regular internal amplifier output to test the behavior and I end with the same result.

Is it possible to output the sound through bluetooth or USB, just to make some tests?
[Android Head-Units] infamazz:
Go under sound and make sure it on intelligent...it's the third option
[Android Head-Units] CamilloCorleone:
Hello, I found a new problem: saved radio stations disappear, totally restored to factory settings. It did like that two times yesterday. Any suggestion?

Edit: the same for EQ
[Android Head-Units] Remiguel:
Thanks for the tip. Already done, but no change.

It is so annoying the HU is really great, only this radio FM sound is missing
[Android Head-Units] teeedubb:
Hi,

First post lists how to backup a system, any info on how to restore it?

Do these units have a recovery, twrp/cwm etc?

Thanks
[Android Head-Units] infamazz:
I had the same problem, I did a reset and it fixed it for me...I didn't have no sound on any of my apps or navi
[Android Head-Units] Remiguel:
Thanks infamazz

Do you mean a factory reset or a hard reset with a paper clip?

I've done a hard reset twice, but the radio tuner is still silent.

I received from the seller the software image (not the MCU). If I do a factory reset, I will lose all installed applications? I should recover all the software by updating my HU, with the image I've received right?
[Android Head-Units] infamazz:
Yes you will... but that was the only way I could fix mine.. I did a factory reset
[Android Head-Units] Remiguel:
Interesting, I will get a try!
[Android Head-Units] infamazz:
But if they send you the recovery...just use that instead...and if that doesn't work, then just do what I did
[Android Head-Units] Remiguel:
I've tried it with lot of expectation :fingers-crossed:. But no improvement on the sound issue. The factory reset wiped as warned all third applications. With the factory state even the music application was unable to scan my USB.

I've updated the HU with the image received and it seems to be like before the reset. Only the Android robots animation and the iGo software are missing. I just need to re-install my favorites apps (Sygic, TuneIt, Poweramp).
[Android Head-Units] infamazz:
Igo is a third party app that they installed...and for the logo, go to extra settings and got the password type 123456...go to the bottom and you will see all the boot logo you can use

---------- Post added at 09:06 PM ---------- Previous post was at 09:05 PM ----------

I'm not close to my car, if not I would send you a picture
[Android Head-Units] Remiguel:
In the Extra setting they are boot logos but only the car brand ones. The android boot animation are set by another application. In this application, they are 3 options Clear; Android & KitKat. The dancing robots are missing but it's really not a big deal.

I will copy the iGo application from my second car

Thank you for your support infamazz
[Android Head-Units] CamilloCorleone:
Hello, about that do you all know if there is a way to install customized boot animations?

Another two questions:

- Does anyone know if there is a way to alphabetically order contacts in bluetooth application? It's barely impossible searching a contact in they are random as they are on my hu!

- Does anyone know hot to show consumption in KM/L and not L/100km in "Car Info"?

Thank you!
[Android Head-Units] Remiguel:
To search a contact, just long press on the phone book to have the search field. It is the best way to find quickly a contact :cool:
[Android Head-Units] lankri:
Hi, I saw that you are using Tuneit. How you can install it into the head unit, it is for alpine only. Thanks for your help.
[Android Head-Units] Txori82:
Hello.

I've bought this unit.

http://es.aliexpress.com/store/prod...Quad-Core-Android-Car/239931_32654622521.html

Processor type: QuadCore-R16 1.6G

Android Version: 4.4.2

MCU Version 5.3.18-23-b55-e43101-160219

MCU: E90(5.3.18, HZ, CONFIG, RDS, BC6, Color, NODVD, Rohm37XXX, TEF668X)

System version: 4.5.7_20160108

Resolution: 1280x480 (but on extra settings appears 800x480 very extrange)

My Head Unit doesn't have any reset button...

I've the files of the firmware if someone needs.

Is the same? Because I'm not sure if I could do something to change the android version, mine is really ugly... Spedometer everywhere, colored buttons...

Inside

I would like something like this, main screen is easy with a new launcher but the rest is imposible without android changing...
[Android Head-Units] Remiguel:
Tuneit is also an app to listen radio on Internet http://tunein.com

---------- Post added at 11:20 PM ---------- Previous post was at 11:08 PM ----------

I would say, new launcher with PowerAmp or similar and the radio app page 18
[Android Head-Units] infamazz:
Has anyone notice slow or throttle down download speeds or gray wifi
[Android Head-Units] Txori82:
I have google play problems and I cant install power amp for example. Google play says not comparible...

Y reset the unit and nothing change.

I downgraded and updated android and nothing...
[Android Head-Units] BiliTheAxe:
I also was unable to install poweramp, but I got it to install manually.

Do a search on google for the poweramp apk file and download it.

Make sure that your system is set to install from unknown sources in settings.

after you download it, locate the downloaded file and install it.

It has worked fine on my system with no glitches.
[Android Head-Units] Txori82:
Yes, poweramp is not problem.

But I have some app that neither manually is possible, Root checker for example. I receive an advise that is dangerous but I check install anyway. Android continue installing but in the end I receive a app not installed.

I don't know why...
[Android Head-Units] Hisma:
Yep I had the poweramp issue also. Couldn't install through the playstore but the apk works just fine. I think the playstore version checks for bt, and because these units separate the bt module from the settings it thinks it's incompatible.
[Android Head-Units] dustin.keith.b:
Has there been any solution to the BT module being separated from the settings? I am still hopeful about getting my OBD2 Bluetooth dongle to connect to my headunit.
[Android Head-Units] BiliTheAxe:
What brand OBD2 adapter do you have?

Not all of them are compatible with these units.

I've tried multiple different ones available on ebay, and have had varying degrees of results. Some worked ok, while others worked either randomly, or not at all.

I finally broke down and spent the money on a name brand one, and have had zero issues with it.

Goliath Industry OBDII OBD2 Bluetooth Auto Diagnostic Scan Tool - Engine Light Check Wireless Data Feed To Your Cell Phone -- Bluetooth Scanner Exclusively Compatible With Android & Windows Devices (sorry can't post the link, still too Newb here)

I bought that one about a year ago, worked amazing with my Nexus 5, 5x, and 9 using Torque and Carista. Not so much with this aftermarket headunit. I better just upgrade to yours for the better build quality.

Also, has anyone tried plugging a USB-OB2 directly into the headunit. I haven't seen any conclusive posts about anyone's positive experience doing it. Thought I might dredge up that subject while I am asking questions.
[Android Head-Units] BiliTheAxe:
I had one of those on my single core Android 2.3.7 head unit and it worked fine, but it would not work on my dual core Android 4.2 unit. The current headunit is a quad core with Android 4.4, and the obd2 adapter connects very quickly.

I use mine all of the time for extra dash gauges with Torque Pro and it also works with Dash Command.
[Android Head-Units] fyid:
fwiw, the cheapo $3 ebay model works fine with my head unit, "Super Mini OBD2 OBDII ELM327 v2.1 Android Bluetooth Adapter Auto Scanner Torque"
[Android Head-Units] Txori82:
Hello people. For now step by step I'm finishing things.

- Radio is perfect with the APP you suggested me.

- Music is Ok with Poweramp.

Next steps:

- Phone. Is there any open app for phones? BT?
[Android Head-Units] kenfly:
Does anyone know by the picture if this is the second gen? Also if there is a more up to date system for my model? I would like to update this thing but don't want to Willie nilly flash some updates and brick it.
[Android Head-Units] danknasty:
Hey I was actually interested in getting that for my Benz the 9 inch with the quad r16 but the only thing holding me back is that al the other devices seem to use the quad rk3188 and 5.1.1 android. Does this unit suffer greatly from slower processor and older version of android.
[Android Head-Units] Txori82:
Really not. It's quick.

I like it but android is really ugly in my case.

Maybe you have on a shop called seicane a preatier android...
[Android Head-Units] danknasty:
From the ones I saw it seemed to have fully customizable backgrounds and app orientation/layout. I actually liked having the speedo there but it requires having the obd2 plugged in at all times I assume or it just sits there.
[Android Head-Units] fyid:
yours looks just like mine & the version #'s are very close (see post in my signature to see my version #'s), so i believe you're in the right place. there are lots of firmwares out there but few guarantees they'll be 100% compatible.
[Android Head-Units] Txori82:
And mine? Could I install any of this firmware without problem? Remember that mine resolution is 1280x480...

The radio tuner of my HU is still without sound. I was expecting to receive a new firmware version from my reseller, but they will send me a new IC instead.

I'd like to test with another firmware before changing hardware components.

I saw that some of users of this thread, have already tested IQ Navi.

Is it really a good alternative? I understand that IQ Navi is working with a large number of MCU. Is there any known limitation?

Data of my HU are

A last question: How to do a clean installation of IQ Navi? Just system update?

Many thanks for any help/support
[Android Head-Units] D3LTA:
You have no sound, if have same sort radio and have sound but no high tones in radio app.. all other sounds is perfect don't know what's causing it or how too fix it.
[Android Head-Units] Remiguel:
What is really strange is the sound behavior: The sound is ok with all applications, but as soon as I switch to radio application, even the GPS sound is also muted. For that reason I suspect that it is more a software issue rather than an hardware failure.

D3LTA what HU do you have? yours is from Infidini as well?

I was plane to downgrade to a former Infidini firmware version (I found the 4.5.5) and get a try with IQ Navi also.

I'm not confident by playing with MCU, so I wont touch it for now.
[Android Head-Units] jaackyy:
I'm having trouble changing the LED colour of my side panel buttons.

I've got the " Colour " app installed but it doesn't do anything and going into the extra settings (pw:123456) and clicking on the option to change colour has " Colour 1, Colour 2, Colour 3 " but selecting them doesn't do anything...

Will rooting the unit help me?

Am I in the right thread? These are my HU's details.

Processor Type: QuadCore-R16 1.6G

Android Version: 4.4.2

MCU Version: 5.3.17-16-10-940201-151014

System Version: 4.5.9_20160322

Also, i was able to set the SWC to open the default music app, but now I can't change that button to anythnig else?

any help appreciated, thanks!
[Android Head-Units] Remiguel:
I've installed the firmware 4.5.5 from infidini for test purpose. The HU works exactly the same way as with the 4.5.9.

Unfortunately that didn't solved my sound issue. I've tested the same with a factory reset. No improvement seen.

So I reinstalled the original 4.5.9_20160322

I would like to test with the last IQ Navi software. Before testing it, any feedback of this software from you guys, would be really appreciated.
