RESOLVED: Newbie to Android Car Head Unit - Android Head-Units

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.

[Q] Bluetooth, Car stereo, track names not appearing

Hi,
I have recently switched from an S4 with 4.4.2 installed to the new note 4. When connecting to my car stereo with the S4 via bluetooth the track names of songs playing in the music app and pandora would show up on the deck.
On the Note 4 i have no issues connecting to the deck but now theres no track names.
Is this to do with android 4.4.4?
Any ways to fix this?
Thanks in advance.
Seems to be so many variables in getting this to work. Always had problems with my Note 2... Works perfectly with Note 4 and Ford Mytouch Sync.
Try deleting the pairing on both sides and recreate it.
I thought i tried that but ill give it another go.
No one else have this issue or can say it definitely works with pioneer car stereos?

Didnt work
my pioneer head unit was the same, also i couldn't control it with the head unit.
I ended up updating the firmware on the head unit and it solved the problem, check to see if there is a firmware update for your headunit.

The problem is actually with the car stereo. It probably still runs Bluetooth 1.2 or something. I have the same problem in my 2012 Mazda 3. It has a dated Bluetooth. All I see is BT Audio, however it works fine on Ford sync and cars with more recent BT versions.
I have... inconsistent performance with this. If I am using the Play Music radio functionality, everything seems to work well. If I'm playing through an album though, it seems to get "stuck" on the first track played. The track duration updates but the track name does not. Pausing and resuming will get it to update.
With the same car and my Nexus 5 running the same Play Music version I do not run into this issue.
I've got a 2012 Honda Civic EX with the factory iMid (not navigation) system.
Was using an HTC Evo 4g LTE with a custom 4.4.3 ROM and was able to get track names and control music from steering wheel and connected via bluetooth.
Got Note 4 and lost abilty to see track names / artist info. I can still control the phone via steering wheel.
Unfortunately, Honda issues no updates for my factory stereo. If I go 3rd party unit, I loose steering wheel and bluetooth integration with the onboard mic, etc.
I am hoping that Lollipop will correct some of these things or that Samsung will issue a fix. I've seen a lot of posts around the web where people are having the same issue: prior phone worked fine. New note 4 phone lost track names. This was affecting lots of car manufacturers, factory stereos, 3rd party stereos, etc. Hard to narrow it down to one issue, other than all new notes having a new BT stack.
Just throwing my experience in the mix.

dlitwin,
Take your car to Honda, some Civics/Accords/CR-V, etc have an update for the Handsfreelink module.

Well, a quick update here. My T-Mobile Note 4 received a system update yesterday, and after that the Bluetooth works as expected with my car.

Not really a stereo problem if the thing that changed was the phone. It should be backwards compatible.
Hopefully theres an update in the works to make it come back. Its illegal here to touch your phone while driving and showing the track names on the deck helps with not having to touch it.
Might have to look at using NFC on my cradle to make the screen stay on, turn on bluetooth and connect the music app.

Awesome! In australia we get updates late usually so maybe by the time you have lollipop ill get that update
Still nothing. I got an update but it didnt work. pandora has updated and no good.
Anyone found a fix?
First off I apologize for bringing up an old thread. I recently purchased the Pioneer DEH-4800BT head unit so that I could leverage the Bluetooth capabilities. Everything works great, with the exception of the unit reading my music library via Bluetooth. If I restart my Note 4 and then connect it via Bluetooth to the Pioneer head unit, it reads the library and allows me to browse my music as it should. However, if I turn off my vehicle thus disconnecting the Bluetooth connection, the unit will not read my library without me having to restart my Note 4. Has anyone ever encountered this? I have a feeling there is something on my Note 4 preventing the unit from reading the library a second time without restarting. Unfortunately hours of Google searches on this subject have left me with no solutions. What can I do to fix this? Thanks in advance!

SWM8802 Bluetooth settings missing

Hi,
I've just purchased one of these head units for my car. I can connect my phone to it via Bluetooth just fine for calls and music, but I want to connect the head unit to my ODB2 bluetooth dongle so that I can create a Torque dashboard for it.
However, when I go to the general settings, Wifi is listed but Bluetooth is not. I've searched and searched but there is no way for me to connect the head unit to a Bluetooth device. I've tried various third party apps that claim they are able to enable Bluetooth and connect to devices, but they all just seem to hang when I try to enable Bluetooth. Tried a system reset too, but that Bluetooth option is still missing from the settings menu.
Please can anyone help?
G
I'm also interested in knowing this. Torque doesn't seem to detect my bluetooth ELM327 at all. I also attempted to connect a USB-based ELM327 module, and Torque seems to detect it, but it doesn't work beyond that, and the headunit gives me a low-power warning light.
Hi did you get anywhere with this I have the same problem can't get Bluetooth options to show
I have exactly the same problem. I'm running a PX5 unit from Witson. Custom built for a Koleos. MCU is not a standard MTC device. I have no bluetooth option available in the settings and the stock bluetooth app does not display any search option whatsoever. It seems that it broadcasts itself for other devices to detect it but you can't search for devices. Seems like they may be handling the bluetooth via the MCU directly and not via android which is strange because they openly claimed that this device was compatible with the OBD II dongle that I purchased. They even shipped it in the same package. Will keep looking and post if I find anything.
I had the same problem with a different Chinese head unit. Solved by buying a WiFi ELM327 dongle which connected fine with the head unit's built-in WiFi.
Update to my earlier post...I managed to get mine working over BT with the WITSON unit. In the end I had to disconnect my phone completely and reboot the unit. Then I found a search option on the dialer page. Searching found the OBD II module and I was able to pair with it. After I was paired with it I was able to add my phone again and both can run in parallel. I have not been able to test much but it seems like this continues to work until the unit goes into a deep sleep and shows the startup logo again. If that happens then I need to go through the learning process again. Meh...
Hi friend, just a question, in the dialer where did you find the search option I cant find it in my android radio??
If you have the swm 8802 you cannot connect to obd2 this requires bluetooth 4 and the 8802only support bluetooth 2
Always Connect ODB First
The ODB readers are a tad picky but they connect using the same menus as any other BT hardware (headset, speaker, etc). First, turn on the car ignition, do not start.
2. Make sure no other BT equipment is connected to the head unit or even on & near by.
Next, place the head unit in searching/Discovery mode and then & only then plug the ELM BT Module into the car ODB II Port. Most cars must be 96 & newer. 95 GM with for the plug but won't work. They're usually ODB 1.5, don't ask, your screwed.
Finally wait for the module to pop up and ask for the code, it's 1234 not 0000.
After your paired, THEN open Torque and let it connect. Don't start the vehicle till the car icon stops flashing.
You should be good to go from then on. If you ever have problems after that. Make sure the app is totally closed, force stop and then follow this procedure again.

Mine connected no problem. Did it just like I do on my phone. I just got mine too though. Could be an update maybe
the original question wasn't answered and I have that problem too. I don't have a Bluetooth discovery/search option anywhere. the small bluetooth-like icon on the main panel just changes the color of the leds.
so can't connect new phone. although Bluetooth seems to be working, since an older phone, already paired, is still working.
Following this as my head unit is same. Theres no blietooth menu/option but it connects to a phone.
Ive tried a third party bluetooth manager but all that says is bluetooth disabled by admin??
A fix
That happened to me trying to add and ODB2 bt dongle. I had to use the app for bluetooth linking provided by the head unit. When I purchased the unit, I changed the bluetooth discovery and pairing code to 0000. Well, changing it to 1234 allowed me to add the ODB dongle.
I saw it on a YouTube video, and well, it worked for me. (And no, no native bluetooth option, came disabled for my unit as you said)
Hope it works for you too.
same problem with me
Hi sir did you found solution for this problem. I also have this problem with my native bluetooth. when i turn open system setting bluetooth missing. i try to open using shotcut and found shotcut to turn on bluetooth but when i turn on. it do nothing.
I can play music, make call using bluetooth app provide from head unit. Problem is i cant use it with OBD2 . same with your statement this bluetooth only stream signal to other. this Head unit cannot find other bluetooth.
Kindly please assist me. did this head unit still have hope to turn on native bluetooth or not. I still search many post regarding this issue. But issue bluetooth like this not many discussion.
Hello there,
My problem is some how different. My hu use the bluethoot to find the obd2 adapter but there is no dedicated pair button. I can pair my phone for calls and music but connecting from phone to hu.
My unit is a 8227l from seicane.
Has anyone any solution? Thank you!

Change the pair code in the bluetooth custom app provided, to 1234 and try again.
I had this happen and I think I figured it out.... in factory settings there's an option to choose bluetooth connect automatically or with pin. I checked with pin and was able to pair. I think the options are reversed in the settings
I have the same problem i can't connect to the android 7.1 car head unit any more , the bluetooth setting is missing , the wifi settings appear but bluetooth doesn't appear any more
Anyone can help me to fix this issue please ?

I bought a bluetooth usb adapter and I can't select it on the system. I think this would be the way out, but we need to replace the driver inside android. Does anyone have any ideas?

I have a Teyes Spro with the same Bluetooth issues as most on this post describe. Did you find an answer to your usb adaptor to solve the Bluetooth problem? I was told to add a line to the config.txt file but cannot locate where to access that to add it.
Bought a Teyes Spro headunit and I have a problem with Bluetooth discovery on my obd II and tpms modules. Does anyone know what is in the "Developer" tab? It is password protected not accessible. The 168 factory access code does not work for it. Anyone know the password?

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

PX6 - Android 8.1 - Bluetooth

Hi all,
I have a PX6 for a BMW (from AliExpress - model CCT-BBA22B07) and i've been trying to figure out how to enable and use the bluetooth for more than phone calls and media streaming. I want to connect it to a bluetooth ODB2 device.
The PX6 seems to use some of the original headunit's functions and along with some of its own Android features and functions. For example, i can use the original HU for FM radio, CD, Bluetooth for phone calls, etc. while using the Android for other functions like navigation (and any other android app i can think of).
So i ignored the Android bluetooth for the phone and continued using the original HU bluetooth. However, i've been trying to use the Android Bluetooth for ODB2. I've bought a bluetooth dongle (CSR 4.0 usb dongle) hoping that the PX6 will detect it. However, i can't seem to switch on the Bluetooth on the settings. depending on the Bluetooth App i use, it immediately switches off (1ms on, next millisecond off), or it gives an error saying "permission denied"
I tried telling the PX6 to use the Android Bluetooth instead of the HU bluetooth, just to see if the "Factory settings app" prevents control of the Bluetooth, but i can't find the Android bluetooth on my phone (i'm contacting the seller regarding this).
So now that you have the background, basically, i want to continue using my original HU bluetooth for the phone, and i want to have a full featured Bluetooth on the Android device (like a tablet would have). Any ideas on how this is possible? I'm hoping there's no need to strip the screen and remove electronic components from the PC boards?
wow, I have a similar issue, I am suprised NOONE knows anything. xtrons sucks for support

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.
