Eonon Android 5.1.1 bluetooth issues & canbus issues

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.

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

Erisin 9" Android 8.0 oreo head unit issues

Morning all
Bought a new work van which come with a sony double din headunit and the bluetooth was useless kept dropping the connection while driving, So before i crashed into the back of someone to keep reconnecting it i bought a new headunit, The one in the link below.
https://ebay.co.uk/itm/9-Android-8-...lf-Touran-Caddy-Jetta-EOS-Sharan/142821418704
So far so good apart from a few issues
The torque app does not pair with my OBD2 dongle but works fine streaming from my phone using the amazon music app
The wifi is next to useless and very slow, I can see my home wifi network and can connect to it, Then it disconnects straight away, The aerial symbol shows a maximum strength signal then shows the empty aerial signal with zero strength
Using my mobile in the van as a wifi hotspot works ok but is very slow and pretty much unusable
The canbus decoder is wired wrong i think, I open the drivers door and it shows on the headunit as the passenger door is open and vice versa, The passenger side sliding door shows as the correct door open as does the boot
Have bought the DAB+ add on box but will not be fitting that until this weekend possibly if i can sort out the above issues
Front and rear cameras are also on order for reversing and dashcam useage, again these are not going to be fitted for the same reason
Other than that its a good headunit but can the issues above be sorted out or send it back and get the xtrons one as it's exactly the same?????
I have uploaded pictures to my google drive of,
Whats in the box
Headunit fitted in the dadhboard
Headunit showing different screens
Headunit specs android version, memory, kernel etc etc
https://drive.google.com/folderview?id=1BNqfitMlJSrCySuVWI4ncMUDB6KUSES9
This is the xtrons one would it be any better or would it suffer from the same issues??
https://www.ebay.co.uk/itm/XTRONS-9...613935?hash=item1ca766c2ef:g:uJIAAOSwRChayxq7
Any help on the above issues would be appreciated as i am still in the time frame for sending it back via paypal if its not fixable

I bought the head unit for my Passat b7, seems like a good unit but my iPhone 7 keeps disconnecting or even not connected at all to the phone, also my mobile WLAN connection seems sometimes working sometimes not.

Looking for infos on Joying Head Unit for my crazy project :)

Hi All,
I'm about to attempt to upgrade my Harley RoadGlide's radio.
REEAALLLY like the fact that it will be a all-in-one solution (GPS/Radio etc)
Here is the plan:
Joying 8.8" 4gb /32gb Android 8 unit
Adaptor for 1 DIN radio ( Harley factory is a off the wall size more like a 1-1/2 DIN )
Module to retain handlebar controls (Works like a steering one)
Marine amp (with the remote power on a manual switch so I can shut the speakers off)
Bluetooth transmitter to send music to headset if needed
Before anybody points out the obvious, yes I know the unit is not marine grade..
This leads me the my first question:
How much heat does the display generate?
I was thinking on taking the bezel off, wrapping the whole back in vinyl up and over the edge of the glass and then putting the bezel back on. This would seal the display part since there is not reset/mic/pwr holes in the glass..
Mating the display with the body will be thru a custom device with seals to prevent water getting in at the connectors.
As for the "main" body it is pretty much protected being in the fairing. I will need a heatsink/fan but I think it will be ok.
Now on the operational question:
Can a bluetooth headset be connected directly to the unit? (For listening to music)
Any tips/advice?
Anybody ever done this?
Thanks !

Ok.. just ordered the 8.8" single din 4gb model.
Was 25% off. Black Friday sale. What can go wrong ??
Good thing about that model is that it is solid glass.. no reset/mic holes.. should make it easier to weatherproof.
The fun will begin when the unit gets here.
Lots of config/testing to do before I shoehorn that puppy in the bike.
I'll post pics if people are interested.
Been testing a couple of GPS apps on my tablet right now ahead of the integration and so far Sygic and Osmand are the best I found. Following a preplanned route is a must( ie to not deviate from the plan) , so if anybody has insight please point me in the right direction ?
Patiently awaiting the arrival of the unit...

The beast is here!!
Just received my unit ?
Got to say it is very well packaged
Will setup and start the testing soon.
Stoked!!!!!

Update/ Questions
Hi All,
Well.. the testing is going well.
So far i am able to get all my music audio to the Bluetooth headset by using a transmitter connected to the RCA output.
I had to use an external USB power for the dongle because the transmitter is "recognized" as a USB keyboard by Joying
I am using the soft button on the unit to turn the amp on/off when I want to use the headset.
I am able to use ZLink as well to connect the phone to the unit.
To have the headset capability for phone, I need to have the headset paired with the headset first.
Then I connect the phone to the unit using ZLink/Android Auto on 1 USB input
I can use the radio's display to control the phone and make calls.
All audio/mic is done by the headset. Yeah!
Only 1 problem.. The Joying keeps on wanting to connect Bluetooth to the phone.. Pops a request every so often..
Any way of turning this off? Only happens when Zlink is active...
If I connect the radio to the phone, it kicks the headset off...
Any way to disable Bluetooth entirely on the unit?
Unit is now rooted and I have installed JET.
Waiting for my handlebar controls converter in order to test "steering" functions.
Cheers!

Can't you do that from the settings? Simply switch off Bluetooth?
Or is that when Joying keeps nagging to switch on Bluetooth? ("wanting to connect" can mean to connect because BT is active, or first wanting to switch it on and then connect)

I tried..
The Zlink app automatically turns bluetooth on I believe.
The bluetooth is off in my Joying settings.
It only happens when the Zlink window is "active"
So when I first connect I press cancel on my phone when the request comes in.
All good until I minimize the windows then re-activate it. Then another request comes in from the Joying unit...
I tried to disable the bluetooth in the app settings and Zlink refuses to open.
There is no "access to bluetooth" in the Zlink app settings..
Really more of an annoyance then anything else as I can just cancel the request...
Would really be nice to have some decent bluetooth settings on the unit to be able to connect any devices or change settings.
Or have some ZLink settings to not start bluetooth on demand since it's already been taken care of by the headset...
Thanks for the suggestion
Cheers,

Problem solved! Android Auto using headset instead of Radio for audio
Hi have solved the problem of Bluetooth wanting to connect all the time.
Solution: First time the popup comes in on the phone when connecting USB to the radio (I used Headunit Reloaded but ZLink should be the same), accept and enter proper password (0000)
Once connected, on the phone Bluetooth settings change Joying Radio to No Phone, No Media.
The next time it will not ask to connect and won't kick out the other Bluetooth (Headset)
Android Auto has to be in developers mode to not care which Bluetooth it is using:
To enable it, open the Android Auto app on your phone and choose About from the left menu. Tap the About Android Auto header text about 10 times and you'll see a prompt to enable developer options. Accept it, then hit the three-dot Menu button and choose Developer settings-> Application mode "Developer"
On to the next challenge!
Cheers!

This sounds interesting. Any pics on the install?

Yes pics please, what are doing are weather proofing the head unit or are you a fair weather rider

AUTOPUMPKIN AA0495B issues with some bluetooth devices

NOTE: I tried to post a fully detailed write-up of my issues, with screenshots and links, but because I'm a new member the forum won't let me post this with those URL's in the post. Since there's no way to upload and attach images, I'm happy to provide all of this via alternative means, or update the post with the original links if an admin is willing to remove this restriction from my account (I promise I'm not a spammer of any kind)
Hi all,
First time poster here with some unique issues (at least for me) with one of the newer Android stereo units. (AA0495B)
I've already contacted AUTOPUMPKIN customer support and they were absolutely no help in solving this; I've also done my own testing and tinkering but haven't been able to get anything working so I'm hoping someone here with more knowledge of these Android units can help.
Late last year I got an AUTOPUMPKIN Android 9.0 unit (AA0495B) for my track car; the main reason I got it was to run my track timer apps directly from my car instead of having to run it from my phone in a dash mount as most do; the specific app I use is Harry's Laptimer. Now obviously this app was programmed with phone use in mind, but after a bit of doing I was able to get it working completely on the Android stereo unit, so my questions aren't around that app, but rather some secondary hardware related issues using the unit. Overall this stereo unit has been great and free of any major issues like ones I've seen on other XDA posts about other Android stereo units. The app works, connects to my GoPro over WiFi flawlessly, and records track sessions and syncs to video perfectly. My issue is that the HLT app also supports connecting to other kinds of devices via bluetooth for additional data capture, such as the XGPS160 for obtaining more accurate GPS lap data (The 160 captures GPS coordinates at 10Hz rather than the 1Hz of the AA0495B and most Android phones) and I'm having issues getting the stereo unit to connect to the XGPS160 device.
There are several problems in getting this to work, but to keep things simple I'll start with the first problem and then work down layer by layer as each issues is solved; hopefully, if we can get it to work, this thread can serve as a guide for others to get this stereo unit to connect to this and other GPS devices.
PROBLEM #1 - Getting the AA0495B unit to pair and connect to the XGPS160 over bluetooth
So obviously the first step is to get the XGPS160 connected to the head unit over BT. The instructions for this are fairly straightforward and in the XGPS160 manual which I followed. The AA0495B unit has its own custom UI for managing connections to bluetooth devices rather than using the native OS bluetooth menu. The native OS bluetooth menu can be found in the system menu, however when attempting to use it to pair to devices, no devices are detected. If we instead use the main menu Bluetooth button to open the custom BT interface and then hit the search button to scan for devices, the XGPS160 shows up when ready for pairing, so we know the BT radio is picking it up at least. I then click on the name of XGPS160 and press the Connect button to pair the device. After a few moments, the device name now shows as an "available device" meaning it is paired to the unit (at least in theory). We can then click on the name and click the Connect button again to attempt to connect the device. This is where it stops, as it never shows as being connected. For comparison, the UI does show blue "connected" icons when the stereo is connected to my Galaxy S9. It appears this custom BT UI will only show the blue symbols when the connected device is a phone; I also have an OBDII dongle paired and it will never show as connected from this screen, however apps like Torque Pro are able to make the stereo unit connect to it and pull OBD data from the car. I was hoping that maybe this was a case of this custom UI simply not showing that the device was connected when it actually is, like the OBDII device. I attempted to run the "Bluetooth GPS" helper app to see if I could get it to connect; however the XGPS160 doesn't even show up in the list of available devices, whereas the "OBDII" dongle is listed even though it's not currently connected. Presumably this menu is pulled from the OS's list of paired devices, so if I had to guess, perhaps the XGPS160 isn't really paired even though the Pumpkin custom BT UI shows it as paired?
In contrast, I was able to connect the XGPS160 to my Galaxy S9, update its firmware via the phone app, and install and run the helper apps to pull data from it, so there aren't any problems in the device itself, but appears to be an issue with the stereo unit.
Here are the About Machine details from the unit for reference:

So with all that, does anyone have recommendations on next steps? I'm a software engineer by background (though not in smart devices) so I shouldn't have trouble performing any troubleshooting steps necessary.
thanks!

Figured out the issue
Circling back to update this one for anyone else who comes across this issue. Here's the response I got from Autopumpkin support
"After checked with our engineer,sorry to tell you that our headunit cannot connect to SkyPro XGPS160.the reason is car stereo Bluetooth is equivalent to a Bluetooth headset and it can only be connected passively.sorry about this."
So yeh, seems they cheaped out on the bluetooth module and that's the problem. Now if only I could find a way to disable it and use a USB bluetooth dongle I have instead.

I also have the problem with a Kingbaets K1+ Android 8.1
Unfortunately, it is only possible to establish the Bluetooth connections up to Android 6.0.
Later Android versions have a "castrated" Bluetooth interface.
My consequence was that I bought an OWNICE C500+ with Android 6.0.
With this device, Bluetooth hardware can pair with PIN input.
It works perfectly.

No sound after HU wakes from sleep

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.

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.
