hi
i got this MCU: MTCD_KD_V1.71
Android 5.1.1
RK3188
i updated to MALASYK rom and i got some new and old isuues.
1. 3G dongle, sometime it works, sometime it takes alot of time. very annoying. is there a fix?
2.Seince the update it runs very slow and buggy.
3. when i use Waze as GPS, and i listen to the radio, when the guideness is on and it tell me something, the radio stops but it doesn't say nothing. But, when i listen to Spotify, i can here the Waze directions. any solution?
4. any way to speed up the boot time?
5. Bluetooth is not working properly. I can connect my iPhone, contact are not syncing, i can't here the call from speakers, i can't call form screen, and the microfone works poorly.
6.KD=KYD?
Apple tends to do things in non-standard semi-proprietary way. Please try with an Android phone and see if it works as expected.
Hi
I am currently using Parrot Asteroid Smart, generally I am satisfied with the unit, sound quality is great, BT and other features works good, but the HW is old and max. Android version is 2.3.
I'm thinking about upgrading to newer android and the only possibility I see is one of chinese 2din HU like Ownice C500.
Does anyone have experience if they are any cons of such change? What is the sound quality of C500 compared to Smart?
Any info would be appreciated.

I am in the exact same situation. I was happy with the PAS at first, but it became outdated and frustrating very quickly - the lack of apps supported natively, the lack of ram and storage. Even after rooting and installing Google Play store there are so many apps that can't be run on 2.3. Positives though are that the Bluetooth call quality and voice command is in my opinion unmatched.
I have since bought an Eonon Android unit (rooted and installed Malaysk rom) for my wife's car and the interface is great, the sound is reasonable and the app support is great. The Bluetooth however is terrible, to the point of being unusable, the person on the other end can either not hear or suffers from major delay. This is a known problem with nearly ALL Chinese Android head units and there is a hardware mod but not being very confident in opening the unit and performing the mod properly and potentially voiding warranty is a risk I'm yet to take with it. I also have an issue where the physical volume control knob stops working and sound can only be adjusted on-screen, this is usually fixed with a reboot.
I still have not found a reliable unit to replace the PAS in my car after reading numerous threads that has Bluetooth quality on par with the PAS. Hopefully someone else here can recommend a decent unit?
Joying 2GB Intel is the way to go

Why?
look over some of the various threads on XDA, and feel free to check out the official Joying forum - http://forum.carjoying.com/
For the most part i think Joying gets the least amount of negative feedback, they tend to have pretty good customer service, and they seem to so somewhat monthly updates. I have had the older 1gb model and I currently have the newer 2GB of RAM model, and I'm a big fan:
here is a video review
https://www.youtube.com/watch?v=KzGFDwSFj24&feature=youtu.be
https://www.youtube.com/watch?v=IUP4WGYHIaQ
but dont take my word for it, like I said, if you spend some time reading, you'll see a lot of the other head units have their fair share of bugs and complaints
If you want a fully functional BT interface, go with the Intel 2GB Joying head units. I think they are the only ones with a full stack BT interface available, the other Rockchip based units seem to have a somewhat hacked in BT interface which is limited compared to a full native interface, specially when it comes to how the Android OS can access and control it.
Install the apk from this thread and you have access to the standard Android BT settings screen, it is normally hidden in the Settings app but luckily it's not removed.

Thanks for the info
Few questions:
What is the BT handsfree quality with external mic installed?
Does the radio display station names? Does RDS and AF work correctly?
What is the general sound quality?
Does WiFi module connect with 4G router?
I use the head units wifi to connect to my phone as a wifi hotspot. Works great. BT handsfree with external mic is very good, at least according to those I talk to, I haven't been on the "receiving end" yet..
The sound quality is good, I'm still using the OEM speakers and they sound better with this head unit compared to the OEM head unit. Can't confirm on radio as I actually don't use it much... It does have RDS it seems, but don't know if it works or not. (radio where I live is garbage, nonsense content and music seems limited to whatever the top 20 list is...)

Thank you for the info. Which version do you use? I can see there are 3 different versions of 7" universal unit with the same hardware. The difference is that two of them have volume knob and the 3rd only touchscreen.

Both MTCD and Joying INtel have positive and negative feedbacks....
In terms of BT performance....both have BT Limited to MCU. Even you could pair from the BT standard menu, the functionality is limited. If i am not wront (correct me) both units CAN'T perform CALLS from BT by using google Now. Google Now recognizes correctly the name and it seems to start the call but never is initiated as it can not communicate with the real bluetooth Handsfree on the Headunit.
On the Intel units, the BT and wifi hardware is on the same board as the CPU, Android has full access to it. That is not the reason Google Now can't make calls. This is different on the MTCD units where the BT is a module which is sort of hacked in and Android doesn't have full access to.
I have bought Joying with Intel. BT handsfree works fine, although there are some other problems:
- no voice in Google Maps,
- when listening to the FM radio no voice output from nav apps except of Igo,
- I have connected Alpine active sub to the unit, sub works fine for first few minutes and stops, any idea why and what can be done about it? Sub worked great with Parrot, so it must be some issue with Joying.

I think if you change default nav app to your preferred one, you'll get voice output in FM radio.
For the sub - is the amp still ON after a few minutes when it stops? I have an active sub on mine and have no issues. I'd check on what your source for "on" signal on your amp is.
Google maps voice output doesn't work no matter what I do. As a default nav app neither.
Sub is powered and it works with very low volume settings, ad soon as I turn the volume up it stops working.

We got Google voice output working. Look into the forum.
Strange. Maybe I should reset the unit to factory settings. Reinstalling google maps did not help.
Any idea what is wrong with the sub?

(have seen a few oem ones) if so it would be hooked up with the sub RCA output ? Is the amp powering down ??
If so try hooking the remote line on the amp to an 12v acc line instead. (This is no different to the headunit remote 12v output just that if you switch the head unit off the amp is still powered on , this could eliminate a headunit problem ?)

As wrx216 said. I think it might be bad wiring. try a different SUB "ON" source. For example, I tap in the + wire of my rear speaker as the power on signal for the sub amp.
Google maps voice output still does not work. I did factory reset - it did not help.
I have updated the firmware and google maps voice works fine. But sub does not work at all now.
I have connected remote wire of the sub to constant +12V output (the same as amp. power supply) - it still does not work. I have also tried to change RCA input of the amp. - still nothing.

The UI and other specs are very similar to the HotAudio test preview (thread here). Has anyone had a chance to get their hands on one of these yet? I'm deciding between this or a Joying unit.
Any input is appreciated!
PX3 RK3188 Android 7.1.1 DVD VW GPS 2G ram
Just received and installed this Head unit in my vw touran 2004.
It looks like the specifications are the same : https://fr.aliexpress.com/item/Pure...32582906631.html?spm=2114.13010608.0.0.UFTkAD
The unit is a Bonroad C1120801A4/A5 (RK3188 Android 7.1.1 Lecteur DVD de Voiture pour Octavia Fabia Praktik EOS GPS Navigation Avec 1024*600 HD 8 "
So far, i'm satisfied with the unit :
- Radio is now working and stable .RDS works fine (with the last DCMU update). (You need to put a double fakkra antenna plug to get the radio stable on vw cars)
- GPS IGo is fine but not in French, Waze great
- canbus is functional
- Wifi rear camera ok
- BT external micro (mono) installed, i need to shout/YELL (it is an issue...)
When calling, both mic works (front mic and ext. roof mic)
google voice research unusable
I'm waiting for documentation from the supplier as there were no instructions in the box.
Do not hesitate, if you need more informations, pictures and tests. :good:
I tried Kingo root but it failed.
I also bought a car radio on aliexpress similar to yours. Px3 cortex a9 for ford focus c-max.
I have exactly the same worries as you with the microphone, the one integrated in the facade I have to stick my mouth on and scream.
The one who plugs externally is the same thing.
Many people talk about a worry with frequencies that are not the same in china and here
300-3400 for china
50-7400 for others
If you can root your device you can change the frequencies with Pimp my rom.
Personally I can not root it.
Thanks for the feedback. What's the boot time on this thing? Does it have a sleep function similar to Joying units?

About 15 to 20 seconds to boot. For sleep functions, I have nightlight or 15s 30s 1mns ect ...
I've the same unit but it doesn't detect OBDII adapter. Any solution?
After trying everything to get the microphone that works for the handsfree kit, I decided to cut the 4th leg of the bluetooth module and solder a mono microphone directly on it. This was my last option because I did not have the c32 connector. This has been a success. People hear me very well now.
I have ordered this one - https://www.aliexpress.com/item/4-C...32691433062.html?spm=a2g0s.9042311.0.0.MbBrvn. Waiting for the the item to arrive. The seller would ship it on 17 July 2017 (Monday).

Can you try the following and see if this gives you root access:
Goto factory settings and instead of typing 126 type *#hct#root#
This may give you temporary root access. Now you can install supersu or magisk to make the root permanent.
Note: I don't have this device or have not used any other Android HU; so I have not tried the steps mentioned above. I found this on the internet. Please try and let us know the result.

Is your Bluetooth scanning OBDII with this ROM ?

Anyone managed to fix the bad Bluetooth call quality? Any luck with getting root access?

Hello, I bought this unit, but the 9-inch model without buttons and I do not use the search for voice, the free hands works perfectly for me, but for voice searches they do not work with the internal or external microphone.
Nor can I get programs with self-starting like the Radardroid service start only with the start of the radio, I have to manually activate it at each radio start.
I also have no rear camera, only parking sensors, and every time I put the reverse gear turns off the screen and the voice of the radio to try to connect to the back camera even if I do not have it, this did not happen with my previous radio with android 4.4, only with this new one with android 7.1.2.

(1) In the "Shutdown delay when ACC is off" do you have a new option named "Auto Sleep"?
(2) What is the MCU version you have?

Well you're right, if I have the auto sleep option enabled, but programs like Radardroid can not start automatically with the radio, I always have to start them manually.
Hi everyone!
I have a similar unit.
I think that the problem is with android version. In our case 7.1.1.
I had a problem with my OBDII reader and I updated my unit to 7.1.2 and fix it
Now with 7.1.2 I have the same problem with microphone and also I have a problem with USB cameras. Only the DVR app can connect with but only the first time. If I close the DVR app and open it again, camera dont work.
I want to use the USB front camera with Mapillary and iOnRoad but I cant.
Any idea?
Where can I donwload a previos android version? for example 5.1.1 or 6 perhaps its would fix the problems.
Thanks!
I've had a Hizpo 7" no dvd with buttons mcu xrc 2.54 android 7.1.2 2gb 16gb for a week. Came this way so I can't say about previous versions.
My bluetooth microphones (both) work fine for me, calls hear me fine. Even just the internal mic seems good.
I haven't had any bluetooth connection problems.
Android does not see any microphone, there is no speech input in keyboard settings, google voice search hears nothing. Voice recorder apps hear nothing.
Tried a usb mic but that did nothing.
Can't get usb camera to work for DVR. RCA CVI cam works in DVR but doesn't record, does not work in FCAM app however, though rear does.
OBDII worked fine when I first tried it, haven't messed with it since.
Display clear and good.
Haven't seen any bog, even when running nav, audio, video etc.
Audio is so so, lots of noise. Radio reception seems great and RDS works too. Needs an amp.
Wifi reception is great, just a little antenna on the back.
I really like it but for the lack of voice search. It's really fast, I have a load of apps and still tons of space. Runs everything so far.
Nearly instant on, radio is playing in under 2 sec (probably 1).
GPS works good so far, finds my location in maybe 10 sec or less usually. I haven't been thru Pittsburgh yet to say how well it keep its signal.
I just got MTCtools and dialer and will start messing with them tomorrow, hopefully I can get a mic input to android and get voice working, then this will be really great!
Hi guys,
I've got a monoblock amp for my sub and a 4 channel amp for my front components and rear coax's, however i'm yet to put them in and the car is running factory, other than my seicane px3 7.1.2 head unit (seat ibiza). I've noticed that the volume isn't exactly loud, even at 30 (max) it doesn't really distort the speakers, whereas i'd expect it to, just like the factory radio did. I'm concerned there is some kind of limit to the sound, or the processing is poor perhaps, and wondering will this transfer to my amps giving me low volume sound? Another thing i've noticed is aux input via the AUX rca input, is even quiter still when compared to USB / bluetooth audio, any reason?
The single rca sub pre - out, do these work, along with the equalizer sub setting?
After doing some reading i'm wondering if the likes of viper4android or Arise apps would be a solution to remove and limits to sound, although i've found no info on rooting or if there is a custom rom for this unit, px3, rk30sdk. Is it easy to back up the standard settings/firmware in case of anything going wrong, or not so easy? The MCU version is 'MTCD_MX_V2.59_1'
thanks
Same problem here, also with the Seicane px3 unit with 7.1.2.

damn it thats annoying.. so it's probably a common fault. My big concern is that its not hardware, but software so it'll just make the amp i hook up to it quiet also..
anyone able to shed light? is viper4audio a solution?
I also think it is software. Searched for volume mods but can't find them.

Hello,
I have a PX3 with android 7.1.2 with an abnormally low volume, however, when using the DVD this volume increases a lot, it seems that the volume of android was limited by software.
I'm trying to increase this volume, but without success right now.
Greetings.
Read today in another post to set the original radio from normal to 'boost'. It significantly raised the volume from the headunit.

Thank you!
It's no mod. Read it in a forum about Mercedes radio's (Audio20). The headunit is on the AUX from the original radio so the 'boost' setting on the original radio increases the volume for AUX.
I am unable to find the post you are talking about. The procedure is to enter the factory options (126) and raise the AUX volume in the "voice" menu?
Thanks.

No, it's not in the Android headunit! In my car the original radio/system from Mercedes is still there. So, I have two systems connected. The Android headunit is for the sound connected with the AUX from the original radio. In there I can set the volume of AUX to 'boost'.
It's this system: https://www.seicane.com/android-hd-...hd-1080p-video-steering-wheel-control-s018848
Good Day all. Hoping I could get some help with my new Android 9.1 inch head unit, version 10.1 (Model YJ9213AJ). I just installed the unit and have an issue with the CarPlay (usb dongle) which stops playing almost instantly when connected to Spotify and/or my songs on the iPhone. If I click play again it stops within a second. It also stops playing media files on my USB (local music) when it switches to the home screen, which it does on its own after playing music for approx a minute or two. I reset the system and unfortunately still have the same issue. Also on the bluetooth I get "please connect HFP first" too, maybe related IDK?.
Anyone have any suggestion on how I can try and fix these issues. Thank you in advance.
I had problems with android auto if bt was also trying to connect to the phone as an audio device. Disabled bt audio fixed it.
Then I just dumped android auto and went back to bt
Fixed it. Reset the unit and added apps one by one until the culprit was found. It was the CarPlay dongle app that caused the entire issue. Strange.
