Which Android HU in 2017?

Hi guys, I'm looking to update my now outdated Parrot Asteroid Smart with a new head unit. I also have an MTCB unit in the wife's car (now running Malaysk ROM) that has been relatively good other than the terrible Bluetooth call quality all these units suffered.
Looking around these forums, it seems that the choice now is between an Intel Sofia based unit or a PX5 based unit.
My main requirement is good quality Bluetooth calls and voice commands (ie OK Google). I read somewhere that the Intel has a combined BT/wifi chip which allows OK Google directly, but the PX5 does not, is that correct? I want to be able to utilise voice commands to call contacts or phone numbers as I can with the PAS.
Any suggestions on which brands/models?

I have an intel mtcd and i can't use ok Google to place calls.
Ok Google recognizes the name and it seems to perform the call. The call is never performed. Additionally, after trying to perform the call I found that mcu does something strange as it gets frozen on a mute state (I can't hear radio/music, just a soft whistle) until I cold reboot.
Somebody managed to get it work by using a modified tablet talk app. Added the call permission on manifest and forcing Google now using tablet talk to place calls.
I think is the same behavior on both Intel.mtcd and Intel non mtcd (joying and others)
I asked for this issue if was to be solved but hotaudio guy told.me that in China they have a similar app than Google now and it works with calls too.
I don't know what could be different

The Joying Intel Sofia units has a fully featured Bluetooth capability, you can even bring up the stock Android bluetooth settings screen by using an app from this thread. "OK Google" doesn't work out of the box, but there is instructions on how to mod and use Tablet Talk to enable this. The one who made the mod can't distribute the modded APK as it's a paid app, but the instructions are quite simple to follow and is found here.

So both mtcd intel and joying lack for the same functionality (calls by Google now) from stock.
Mtcd can access to the aosp Bluetooth from stock

Correct, but I don't think it's possible to bring up the stock Android Bluetooth settings screen on the MTCD PX5 units, not sure of the Intel Sofia ones. There are several models of the Intel Sofia boards, some with built in wifi, bluetooth, and so on, and others without that so it depends if MTCD uses the one with or without built in BT. Traditionally, in MTCD units and previous models, use a bluetooth module on the "motherboard" which is kind of hacked in and is not fully communicating with the system board, so the Android OS doesn't have direct control over it. On the Joying Intel units (and maybe MTCD with Intel), the BT is on the CPU board itself, allowing Android to directly control it which is why we're also able to bring up the stock Android settings screen for BT. But for some reason, Joying and I guess the MTCD people as well, has removed the Bluetooth entry from the stock Android settings app, but with the simple apk from the thread I linked, it can be opened with no issues. I've used it to manage my BT connections rather than the awful Bluetooth caller app they included... You still need to make use of the default caller app in some ways, as it seems to be deeply integrated, and I haven't found a good way to automatically sync the Contacts from my Google account yet, all the unit wants to do is to delete all my contacts when I try to sync, which is weird... I sideloaded a Contacts apk, but it didn't really work.. I guess someone would have to dig deeper into the OS in order to get full functions from the Google dialer and contacts apps, which would be cool but probably unlikely. But I am pretty sure this is the same on all the units, don't think any of the head units supports the use of Google dialer or contacts.

Mtcd can open aosp bluetooth screen...but for paring you nees the customized screen in which you change the pin of the bt device to pair with.
On aosp screen I can see which bt devices are paired
Similar issue with contacts in mtcd Intel....I can't sync my Google account contacts...only few numbers (without any logic pattern) are synced and the rest not.
I downloaded contacts app and I gan get all the Google accounts contacts but I can't use them for calling (once I mod the tablet talk app I could do)

RK-A715 Generic Android head unit

Hi. This will, iirc, be my first ever post here but have browsed the forum for a while for Android things. I have just bought a generic Android head unit:
(ah, no links for me...)
2Din-7in-Android-7-1-GPS-Navi-RDS-FM-Radio-Quad-Core-Car-Stereo-MP5-Player-Cam-
This model, but without a camera since I already have a cam. Anyway, this is not the issue. I am trying to get info about it and the seller is not exactly full of help. I suspect they don't really know much about the system. I have got it working fine: Radio is good, installed Poweramp, Sygic navigation etc etc. I also installed Torque pro as I have used it on my phone. My problem is that when I go into the settings there does not appear to be any option for bluetooth. There are very few options in settings in fact and I cannot see any way to pair up my bluetooth obdii unit to the head unit.
I realise I have not given a lot of info here, but there is not much info available from it though. What I can find is:
About Car Machine
Model K6_13_LH
Android 7.1
Kernel Linux Ver 3.4.67
System: K6_13_LH_V2.0.1_20181107
MCV: CM_0.4730.0_180918_17:36
APP: MT1002_V1.0.9
Bluetooth Aug141108
it has an ARMv7 Processor rev 3(v7l) with 1GB ram and 16GB nand flash.
The steering wheel controls don't work either and I know my canbus adaptor is working as it worked fine on the last unit I had.
Any help you guys might be able to offer in the way of pointers for O.S. or even how to get the proper android settings on the machine would be really useful. Ta in advance, and I was not sure if this was the correct place for this post so if not could a mod shove it where it should be, if not here.
[Update]
Just ran some diagnostic tool on the unit. Hmm, It is reporting Android 7.1_KitKat! I suspect this is why the settings menu does not look right... It's also showing a build of ALPS.KK1.MP1.V2.11 so I might be able to find something here for the unit?

I'm guessing that's a no then!?

Hello man.
I bought plenty of android head units.
those devices is a BLUETOOTH READY,
which means ., You're able to connect to your phone and check address book and make phone calls also listen to music through the BLUETOOTH app in menu, NOT TO BE FOUND IN SETTING.
you can think about it simply it's a Bluetooth that's independent from the android system.
so you'll not be able to find and connect to OBD's tools whatsoever.
hope this helps
regards.

I have the same unit. The cpu is MT6582 it's a quad core.
Kingroot failed many times (said it clearly) but, after some reboots, finally succeeded (without saying it clearly).
Once root, I used a shutdown app to boot into recovery, but the buttons are not responding. It also managed to boot into fastboot mode,
but my pc doesn't see the device (I've tried both usb ports). Maybe it needs a driver ?

China headunit flash Android Auto.

Hi all,
Some time ago I found a thread on here that directed people how to reimage the head unit with an Android Auto. Is this possible for all head units, or are there things to watch out for? I tried searching but could not find the relevant info(Could be on me).
If I go into About Device of the Head Unit all it shows me RK3368 as name, no more info. All I can find is a thread how to update a headunit with the PX5 to Android 10, which it is already running. If possible I'd really like to flash Android Auto on it, as the current solution feels a bit like a bandaid solution.

Bump

Found some more info. It's a S32F0 MCU, with a PX5 board.
Still trying to figure out if it's MTCB or MTCD and if I can flash Android Auto on it. Any help would be appreciated

Okay so here is an obvious question - why on earth would you put Android Auto on a real Android device? Android Auto is a scaled down version of true Android with some "lite" functionality and support for some basic apps. Android Auto is for those who (for some reason) can't install a proper Android Head Unit.
To put it simply, you can do everything on your Android that you can on Android Auto but not the other way around.
You have S32F0 as MCU, meaning it's not MTCx. Luckily for you, you can still use the only mod that matters - Malaysk. Forget anything else. With Malaysk you can customize your head unit with nearly no limitations to make it fast, user friendly and overall just awesome.
Go to this thread and follow it's instructions.

Hi Ice,
Thank you for you answer!
My main reason is the ability to mirror screen. I don't have a 4G dongle attached to my radio, as that is quite expensive over here. So I was thinking to be able to use my own phone as mirror onto the radio to navigate, play spotify etcetera.
For example I can copy my phonebook to the head unit, unfortunately both me and my wife use the car, which causes a very long contact list with duplicates etc.
What I've seen with friends is that Android Auto fixes some of those issues, as you don't run a seperate instance of the phonebook or whatever, but it's a mirror from your phone.
I've seen Malaysk's post, but also read in the thread there are quite some issues and support is flaky at best. Are those posts stirring sh*t for no reason, or do they have a point?
Finally, the seller claims my headunit is real Android 10, with build number 205150. I cannot find anywhere if this is real Android 10, or the so called fake android 10.

Mirror screen functionality on Android Head Units is shaky at best.
You don't need 4G dongle - hotspot from your phone to give access to the Internet on your head unit - that way you can run any Android app on the head unit, Spotify, YouTube, Internet Radio etc etc. Make sure to give full permissions to your phone
Use BlueTooth on your phone to use handsfree calling. Use Google Voice to dial any number (no need to mess with Contact Books), your wife can do the same and your Android Head Unit will not sync contacts back to your phone
I know Malaysk developer as I'm also a Russian-speaker and his work is exemplary. If anything, his firmware is by far more stable and effective compared to anything you get from factory. People who complain about it, simply do not have the right skills of installing it and using it. Spend some time with Malaysk tutorials - well worth it. Malaysk also offers ROOT natively and Viper4Android which means you can tweak most parameters on your head unit and considerably improve the sound in your car.
Doesn't matter what Android version you have. You should go with Malaysk firmware for Android 9 (most stable). You will need to get a "rollback" software to successfully install it if your Android is anything but version 9. For that you'll need to purchase MOD Installer Pro 2 for €10
Whatever is possible to do your Android Head Unit will only be possible with Malaysk. If Malaysk can't support it, then it's simply not doable.
You can also look into "profiles" on your Head Unit. I.e one profile will have your stuff, and the other one will have your wife's.

Chinese Head Unit - How Frustrating Can It Be

Hello All,
There is much information on this forum which has helped me so far on this android head unit journey but I am almost at the position where I might throw the damn thing out of the window and reinstall the basic manufactures head unit.
I bought the head unit from a dealer who is no longer in business and cannot contact them which closes off the normal route for enquiry.
The headhunt appears to be a generic Chinese manufacturer. The config shows as:
MCU Ver: DH200729T512188X611200805
FrameWork: 9 PQ2A.190305.002 eng.work2.20201208.100955
Android Ver: 9
App Ver: 2020120801T_1280x480_970
Tablet: rkpx6
The bluetooth function has been disabled which was originally a problem when using an iPhone as you have to hotspot every time. I overcame this with a wifi dongle and 4G card.
The GPS is terrible as well (part of the problem is the number of high rises that shadow the road). One of the main reasons for upgrading was the navigation which I generally cannot use.
So I thought a CarLinkit adapter would solve all of my problems which it did - although I get horrible screen interference that makes the unit completely unusable. The interference is completely random and CarLinkit have said that the problem is the head unit and not the adapter.
I've removed the adapter now and have to use my phone for navigation which works but doesn't solve the problem I originally tried to solve.
I seem to remember that the android version was originally ver 8 and it appears to have upgraded itself to version 9. When I play music know it takes about 2 minutes for the sound to come out of the speakers (even though the music appears to be playing). It only happens on the first boot of the head unit.
I'm currently banging my head against a wall with this technology and it appears that updating and not knowing exactly what you are doing could brick the system.
So my questions boil down to:
a) are my carlinkit issues really related to the head unit?
b) why would sound be delayed by 2 minutes after the unit has started?
c) what is the latest software I can apply to this head unit?
d) is there a better unit that I can install that will be much more reliable out of the box? there appears to be other head units available although I need a RHD option which many of the sellers on AliExpress saying isn't available.
Hopefully, I can gain some experience from others on this forum.
Thanks in advance,
DC

Any android head unit with less than 2GB RAM will be a dead zone to run apps or the OS. Apps crash a lot and OS doesn't perform well. I am not sure about your head unit's RAM capacity.
Alternatively, I would suggest uninstalling/disabling the apps that you don't really require through system settings >> apps

Pumpkin PX6 Newbie with Questions:

Hi,
I just changed my original VW RCD510 against the Pumpkin PX6 AA0708B with MTCH_HT_V3.82_1
Now I have several Questions:
1. Can I change the App Icon symbol? There is ugly BT Symbol wich leads me to the phone function.
2. Can I remap the BND button to thje DAB Radio or even better can i integrate the DAB Band into the Radio app?
3. Dies Android Auto Wireless work?
4. Is there a better ROM fpr this head Unit?

Hi
1) As far as I know, there is no simple replacement of icons in the factory firmware. You can try, for example, the car launcher from google play and you can also use your own icons here.
car launcher - Android Apps on Google Play
Enjoy millions of the latest Android apps, games, music, movies, TV, books, magazines & more. Anytime, anywhere, across your devices.
play.google.com
2) You can try MtcdTools-Control on android 10 is the solution on the last pages.
https://forum.xda-developers.com/t/...yers-customize-buttons-voice-control.3436789/
Unfortunately, it is not possible to integrate the DAB band into the Radio application. If you want at least a better FM radio application, I recommend NavRadio+.
[Dev] New "NavRadio+" ported to MTC devices
After releasing my NavRadio+ for Allwinner and IntelSc9853 devices in december, i finally ported it successfully to MTC/HCT based devices (PX3, PX5. PX6, PX30, Snapdragon655). I paste here the first post of my other thread as a presentation of...
forum.xda-developers.com
3) The Z-link adapter can't do it, but I managed to do it using Headunit Reloaded Emulator for Android Auto, the procedure is in the attached video:
https://play.google.com/store/search?q=Headunit Reloaded Emulator for Android Auto&c=apps
4) Alternative rom include Hal9k and Malaysk, the basic version is free and you pay for updates, it's up to you whether you go for it. Just be careful, you own a new board with MCU MTCH, which in the case of bootloop has not yet been able to be connected to the computer using OTG, so the repair is not yet possible. There is already a user here who has MTCH and after updating the firmware he has a brick and does not know how to connect the new board to the computer, it has different pins than the previous type of boards.
https://forum.xda-developers.com/f/mtcd-software-development.7379/
MTC device... has various bugs, sometimes it's better to put up with it, because mindlessly updating the firmware and MCU, may not solve your problem, on the contrary, it may bring more problems.
For example, the last error is the application crash, which is caused by the last updates of the android system webview and chrome. The solution is to uninstall and disable these updates, reboot the device and ignore any update requests. If you don't have this problem, then be happy, you have a newer rom that already fixed this problem.
