hi guys
new to the forum, hopefully someone will be able to help me
my unit has stock MTCC-KLD6-V2.97 Aug 02 2016 with a RK3188 and 1024x600 screen
Firstly the Bluetooth is not working, quite a lot of apps hang at the part where it try's to turn the BT on, especially one app i really need to work.
I honestly don't know what model of BT chip is installed in the head unit, apparently its BT 4.0 as listed on there website
I have been into the factory menu and changed the BT from WQ_BC6 to WQ_BC6B (as suggested somewhere in this forum) but it has made no change and the BT is still hanging at powering on.
Eonon have told me that the Bluetooth only work with devices that don't require a pin and the radar detector device i need to connect does not require a pin but still it does not work.
Not quite sure if eonon has set the setting wrong and i need to change it or i need to goto a custom rom or I need to pull the unit apart to find out.
Found someone else having trouble getting there ALPconnect app to work aswell on these units, in know ALPconnect wont work on older unit like the 4.4.4 as they only had BT 2.0 and the ALP BT only supports 4.0, but this android unit has 4.0 so it should not be a problem but it is.
sterod said:
The app I use, ALPConnect, does the exact same thing. Fortunately, the hardware on mine includes a hardwired speaker and GPS setup that work standalone. The benefit of the app was to get a nice big visual notification of a trap, as it would come into focus, duck the audio and play an alarm. It would also report the frequency of the radar and the type of laser hitting me. While I can get by without all that, I can't have the music blaring like I usually do, as the little speaker is only so loud and the Joying head unit doesn't have Mute Input wire to duck the audio.
While this is going slightly off topic, you may want to look into the AL Priority, it can interface with your V1 too and you will also gain laser protection. This thing has saved my a** countless times and paid for itself already many times over.

Secondly the control menu in the android head unit for accessing the cars buttons via cambus does not work, all steering wheels button seem to communicate back and work, but i cannot set my clock on my mazda 3.
Also have noticed that the radio wont mute when notification occur or when using other apps like google maps, no way to set the different volumes in this stock rom. Have played around with the factory menu volumes but it makes no diffidence.
Is it viable and worth changing to a different ROM, like Malaysk? or should i message eonon?
any help would be much appreciated
thanks

I'm having exactly the same issue with a Pumpkin MTCC-KLD6-V2.91. (RK3188/1024x600)
The device I want to pair with appears in Bluetooth settings (with a phone icon?) but connecting to it does nothing. It's just a Bluetooth SPP device, like so many other devices.
Malaysk's ROM (from 7/25) doesn't change anything here.
Any suggestions would be most welcome.

Waiting on a reply from Eonon, but initial news is not good.
Some serious BT issues in this model the MTCC
Anyone know if any Malaysk's Rom's avalable for the MTCC-KLD6-V2.91 that have no BT issues
I'm having the same issue, though my unit (MTCC KLD6) does not show any devices at all to pair with, and the car unit does not appear on my phone.
I'm wondering - if I take a usb BT dongle and attach it to the usb cable, would that work?
I think it might be another issue with your BT, it should connect to your phone at very least.
Have you had a look in your factory menu to see if the MCU has the Bluetooth option set?
Password for me was 126
Unfortunately the unit does not support external USB Bluetooth and probably never will, unless the manufacturer MTC/Klyde adds the required drivers to the unit or a Awesome developer by some stroke of luck here adds it to the unit. I doubt to see the feature in this unit

Thanks for the reply. Yes, i checked to make sure Bluetooth was enabled in the system settings. I've tried a few of them (change setting, reboot, attempt pairing), i guess the next step is to try them all one by one to rule that out. I've sent an email to the seller to see if they have any ideas.
The vendor told me to connect the Key-1 & Key-2 wires from the canbus to the car, not sure why they'd think that would solve BT issues?
Did this fix the issue? I'm unable to see any Bluetooth devices and other Bluetooth devices don't see it.
Sorry to dig up an old thread
I have the Eonon GA2180a (android 10) - and having similar issues to here
I want to pair a bluetooth remote (read, steering wheel controls) to the head unit, but the bluetooth search just shows blank! I can connect to it using my phone but it appears some things are hidden to connect to with these android units? Looks like the bluetooth 'app' is the only way to connect too, theres nothing in the android settings to access a bluetooth menu or anything.
Did anyone get anywhere with this ?
cheers
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.
Hi,
I have one of the cheap Chinese Android 9.0 headsets with the PX6 Octa-core Processor 1.5 GHz RK3399 (Radio Chip NXP 6686). The model is Fongent Car Android 9.0 Radio Multimedia Player PX6 4G RAM 64G ROM.
The problem I have with it is that the radio will not stay on any station that I choose. Everytime, I switch to a programmed station, it starts to scans after like 10 second and always stops on the first station in memory that it had found. It is getting very annoying now. I tried to fiddle around with the AF TA PTY settings but that didn't do anything.
Anyone has experience with this radio app? Is there another one I can use that doesn't need internet connection to use and can use the antenna?
Please help!
Thank you.
Somewhere in the radio settings you must also select the correct region: japan/europe/etc.
Did you do that?

Yep, i had to do this on mines when i first got it. it was still set to China. Also if you flash the wrong MCU file it could also cause this issue.

I didn't flash anything. The unit is as it came from the factory. I did change the region to US. The radio has automatically programmed different stations under P1, P2, P3, etc all the way to P18 I think. But always stops at 88.7 New station. Even if I choose a different station like P5 or whatever...I get to listen to that station for like 5 seconds or whatever and then it starts to scan and then stop at 88.7! So frustrating. To the point, I just want to use a different FM app for this. But I don't know of any that uses the FM radio to broadcast instead of looking for an internet connection. I am not looking for internet radio.

It happened to me with some radio stations, I solved the problem by turning off the TA.
First question did you contact your seller about this? When you do get to listen to a station does it sound clean? Are you moving or parked? Can you manually tune in or enter a station frequency and see if it starts to scan again? It's possible your car has an amplified antenna and it needs a power injector. Otherwise I'd say something is wrong with the radio and you should send it back.

No I did not contact the seller in China about this. Yes the station sounds clean and clear. I have tried it while parked and/or moving. It doesn't make a difference. Yes I can manually move the tuner to a different station and it plays for a few second and then again starts to scan. It does NOT stay in a particular station other than 88.7. Everything was ok with the stock stereo that came with the car. Is there only on radio app on Android 9.0? Can I not try a different radio app to see if that work? Mailing the unit back would be more hassle that it is worth. To me it is a software issue or some settings/tweaks that needs to be made.
Well I understand that shipping back to China is less than ideal, but your seller is better placed to help you than any of us especially with the little bit of information you provided. Best case they can give you an MCU update that could fix the problem or at the very least work with you to adjust settings in the service menu. Or they may realize the MCU is defective and send you a replacement. The only alternative radio apps I know of are only for MTC MCU. Yes the radio chip is controlled by the MCU so you're not likely to find a generic radio app.
Hey Guys,
i have my head unit now for about 3 Months and i costumized everything i could including the Factory settings!
I have some problems where i cant google a solution or couldnt find one by myself:
First and the biggest for me:
The Bluetooth CallApp sucks - i can't sort by first name - its only sorted by last name
Is there maybe a ther app i can install?
Second Problem:
I cant finde or activate the Developer Options - tried every app on the playstore! not working
- a less big problem - i would love to get it done - but i dont see a chance someone can help me with that...
In the Factorysettings under the Tab Canbus ill have 2 Options that kinda work for me.
78_Jeep
and 48_Jeep
on the 78 Setting, i have all the Settings for my car in the Menue (light, brake etc) but with this setting my steering wheel app dosnt work. it only has a few "preset options"
(Yes i changed the Steering Wheel Canbus Type)
With the 48_Jeep Seetings the Steering Wheel app functions perfectly and i like how i can costuomize it, but the "Settings" app is gone - and my rearcamera curve strings are gone
So is there a way to use the 78_Jeep canbus type but for the steering wheel the 48 settings?
i appriciate every help and if someone needs more details - i will provice everything!

Yes, this section is very alive.
You do not mention which kind of unit you have, which android version, etc, etc. That is like mentioning "my computer doesn't work anymore. Help".
If you have an MTC unit you might have luck in the MTC threads. There are multiple custom roms also having bluetooth mods, but BT mods are really hardware and MCU dependent. There is no such thing as a good BT app.
Developer options: On some units the settings app has been recompiled removing quite some options like developer options or bluetooth settings.
Jeep canbus settings: You can only hope for a Jeep owner to react. Besides: there are so many units. Mentioning the 78 or 48 jeep version might be specific for one type unit that nobody has.
Everything you mention is not on my units.

You have an MTCE unit. The experts on those units are in the MTC sub-forum, not in this sub-forum.

Hello sir!
I too have a Jeep Renegade (2015 though) and am currently ironing out the kinks of my new radio.
My unit is a Dasaita HA-5288-v940 , PX5 w/ Android 9.0 and I have to use the same canbus settings
as you to acquire steering wheel control.
One thing that did help me with my steering wheel keys was using the settings built into the FCC Launcher.
There was an option to switch the steering wheels keys from like 'SW'? to CANBUS. Selecting CANBUS allowed
me to map my keys correctly. I left my canbus vehicle selection to the same one as in your picture (Simple).
Note: you can verify if this is the maker of your canbus by taking a peek at the decoder.. it will be made by
'Simple' or 'High' etc..
FCC is the first 'headunit specific' launcher I've tried.. but playing around with it
resolved a few jeep specific issues. Eventually I'll throw Nova Launcher on the thing when everything is working.
I am currently trying to figure out why I can't hear call audio, but can hear ad2p without issue...
My BT module appears to be a GOC-MD-705D and has to use the WQBC6 module (from what ive tested).
Callers can hear me, but I can't hear anything My harness wiring is labeled for a 'CHEROKEE', but I've
confirmed with Dasaita that I appear to have the right harness. Their support from their official ebay
store have been really helpful. I'm super hoping to resolve the lingering issues I have.
I have spoken with Dasaita support about my issues and through the conversation I have been told
that developer options has pretty much been removed. =/ I was hoping to see what bluetooth codec
was in use and see if me matching it on my mobile would resolve the audio issues...
By all means if you've resolved any issues Jeep specific send me a message??
I've had my unit for maybe 1-2 weeks now and seem to be making things a 'little' easier with every change.
I'm going to look into Viper4Android to help with some audio improvement and hoping to find a better
'bluetooth dialer' application that is better than the factory installed one.. I am totally new to the head unit
world, but trying to learn as much as I can.
I'll try and remember any specific Renegade tweaks that have improved things for me and send you a message?
I can't tell you how relieving it is to find another Jeep Renegade owner who gave U-Connect the boot..
@broach4313 I know it’s only simple but for the Bluetooth audio that you can’t hear have you tried making a call and then when the call has been answered then increasing the volume? It is a separate volume for a Bluetooth call and I had the same problem a few week back, then I remembered I turned the volume down for some reason when I was playing around with it.

This worked for me : factory settings, type code ADBON and press enter/complete. Developer options menu then appeared. (PX5, 4gb, Android Pie)

From what I see the volume is up. I can hear music via bluetooth when its played over a2dp. I appreciate the help though!
I just updated to the most recent firmware for the unit. Not change though.

The volume on a2dp music and on Bluetooth calls are 2 different things.
Try making a call in the car when your Bluetooth is connected to the unit, then when the call is answered then increase the volume on the unit. You might find the volume is currently on 0.

Nope, volume is up. I generally only see a single volume meter (sort of goes for everything?) unless I go into the
canbus settings and then i see notifications, voice, bt etc... everything is up.
Just this one huge problem solved and I'll be happy thinking about rooting the unit to gain more control, but
not sure if this is a software issue or maybe wiring related to the harness. I'm out of ideas. :|
I'm a newbie to this site so apols if I have contravened any site rules!
Hoping someone might be able to help. I bought a 12.3inch HU on AliExpress. Its model number is uis8581a2h10_Automotive, which I think is a FYT HU. It's coded specifically for BMW.
After a full boot everything on the HU works fine. But then if I stop the car, for example to grab something from a shop, when I start the car again the head unit starts up instantly but there's no sound despite Zlink5/Spotify appearing to run properly on the screen. The only option to get sound back is to reboot the head unit and wait for Zlink5 to reestablish a connection with my phone (a Galaxy S10). Interestingly though, even when the music fails to play through the speakers, if I press the microphone button, Google Assistant plays sound and can properly make a phone call played through the car's front left speaker.
Also, when I'm getting no sound after the HU wakes, if I switch to the DAB app, I can hear a millisecond of Spotify music before it cuts off, and then the DAB app also fails to play sound - although it too, like Zlink5/Sportify, responds properly onscreen. So the HU seem to be playing music after waking from sleep, but just not routing it to the amp.
Apparently this unit is supposed to output sound via an aux cable which plugs into the BMW stereo's aux port. However, my unit plays music through the speakers on the aux setting whether or not the aux cable is plugged in. Not sure if that's affecting things?
The final issue is that Zlink5 won't work with bluetooth and WLAN/hotspot at the same time. It switches off WLAN while connecting to my phone via Bluetooth. If I then enable WLAN and set up a hot spot, Zlink5 either switches WLAN off and reconnects via Bluetooth, or else it will connect to WLAN, after which music pauses every second or so.
The sellers have sent me an MCU update file, which I have applied, and I have also tried every option in the HU settings for Car Aux Switch Mode. I can't think of anything else to try.
Can anyone advise whether these problems are likely to be software or hardware related? And has anyone any ideas how they might be resolved?
Many thanks!
In regards to not being able to use Wi-Fi and Bluetooth together when you use zlink it uses the wifi to connect to you phone in the background. If you manually turn it back on it will disconnect from your phone. My advice would be to put a SIM card in your unit.

Many thanks for getting in touch Marchnz. The MCU is ZLH_BMH220425A_8581. The original version was ZLH_BM_OS_1.37, but the seller has since provided an update to ZLH_BM_OS_1.53 which has fixed the problem.

HI there, I've found the update but it's 1.4Gb or so. Can you send me a DM with your email and I'll send it to you via Wetransfer? Obviously its use would be at your own risk, as I'm not sure whether it will work across different manufacturers/companies.
