android headunit help needed - Android Head-Units

Hello all,
I installed a chinese headunit to my car (grand cherokee 2013 with premium sound system),i had to modify the wiring harness becuase the sound system only receives the front speakers and the amplifier in the car does the rest of the work, now everything works fine except call audio in carplay because it seems to use only the line coming out of the headunit to the back speakers, call audio on bluetooth works well.
i have tried everything possible in the available settings in the headunit but no luck to make the integrated carplay to use the line of the front speakers, carplay uses a built in app called car link 2.0 which doesnt have much settings to customize it.
i am considering rooting the system to gain more access to the settings, and hopefully find a work around, the attached image is the info of the headunit, it says android 13 but actually it is 8.1, i need help rooting it and i have no experience wahtsoever in android systems.
or if there is a work around this problem without rooting it, it would be a great help, i have tried all the possible solution that show up in google search and no luck.

[Joying] using FM transmitter controls, to control headunit

Hi,
I searched the forum and internet and couldn’t find an answer to my issue. So recently I realized i wanted to control my headunit via Bluetooth controls. I have a Joying single din headunit (doesn’t actually matter) and the original joying iDrive like remote is simply too big for my center console + I hate the aftermarket Bluetooth buttons for steering wheels. So I saw some cool looking fm transmitters on AliExpress which feature bluetooth Media controls + two usb charger slots which looks perfect! My cigarette lighter is placed in a slim slot near my handbrake so that would be a perfect solution

My question is: I want to modify this transmitter in order to connect the headunit to be able to use its Bluetooth media controls BUT not use the actual FM audio output feature. The look and practicality is very convenient but the FM function is useless for me since I’m using Spotify and CarPlay on my android headunit too. Would that be possible ??
Thanks in advance

THanks!
I have the same problem and no solution for this
Temporary it helps to reset the bluetooth settings in "apps". Then I can connect to "GocAndroid". But after the next start it is again on CAR KIT and no connection ist possible.
Did you solved this issue? I have the PX6 with Android 9.0
Same Problem. Please help.
From the reverse engineering I've done on the bTSuite.apk, which is the app controlling the bluetooth screen, the CAR KIT name and the 0000 pin is usually selected when the car cannot find the proper configuration code for like bluetooth module, type of car, type of UI and so on.
The flow of the app, once you open it, is filled with conditionals for each bluetooth module, type of car and so on. If the conditionals reach the end because it cannot match the correct code, then it defaults to that name and pin

Joying Head Units Bluetooth workaround?

Sorry to bother you guys but figured I have tried two of the resident experts on this type of stuff with no luck, and I apologize that I am not very knowledgeable on this stuff. I totally redid my 84 Monte Carlo SS both outside and now finishing up the inside of it. While doing so I came up with the idea of having a dedicated head unit run a backup camera, air ride controls, and other accessory type of stuff. While having a second unit run the stereo and front facing DVR, I thought I was all set because it had Bluetooth and I avoided the issue of having my phone run bluetooth stereo on one while the other would be able to bluetooth for the air ride.
What I currently have is these two units, JY-UOS02N4PX5S and UK-JY-UOS01P4V. The UK-JY-UOS01P4V is the unit I was hoping to run the Ridetech air ride app on to control the air ride. But I can change how I have the two setup if it would make a difference, but think they are pretty much the same specs except that the UK-JY-UOS01P4V has fast boot which is part of the reason for choosing to run it on the accessory stuff. Thanks for your time and sorry for creating another thread but have searched through and not found anything related to my specific units. Here is a pic of the basic setup of them to mimic modern cars to a point.

Which Unit do I have (want new Rom)

Can someone figure out what kind of Android unit this is?
Use to have PX3 and PX5 on my former cars , but this one is not that easy to recognize:

They sell this unit as Prius 20 Android unit ( https://nl.aliexpress.com/item/4000521643427.html?spm=a2g0s.12269583.0.0.7ed46eefoMcttb )
It working fine but miss some things I had with Hal9K, so would like to know if this unit will be able to use this Rom (or if not possible other Rom)
As I see it's not a Rockchip, but Intel SC9853i
What are you missing?
Seems it has Android 10 or A fake android 10.
I want to had a ad-blocker. And this unit does not give me the normal Settings page of android when entering but a self made menu. Only in some occasion i can get some normal Android setting
i need to give permission to use 3rd party apps because my Online TV app is not working.

			
				
thanks..So I do have a Joying unit. That is a start
unfortunately all firmware on given link are Android 8.1 and I run already 10.
Need to do some research how to root and install new roms. Never done this on a Intel unit
Then install Quickshortcutmaker from play store and search for the application Search Suggestion. Through this Android search i found all hidden settings in my unit
Thanks..Will try that

Factory pattern & bluetooth issue for C-class Mercedes Benz (W204) Android Head Unit

Dear All,
1) Recently purchased and got a android headunit installed, however we are unable to find the factory pattern password to change some mandatory settings.
2) In addition to this, I'm unable to find where I should connect with bluetooth. The person who had configured the system connected it for me, however it doesn't seem to work now. I can only find the android bluetooth settings however this is called "ANDROID BT" whilst the previous one was called "Benz_216" or "Benz 216" if I recall correctly. The person who has installed it doesn't respond so trying to figure it out myself.
3) Would like to have wireless carplay on this device, is this possible?
It's this model for the C-class MB W204:
Mercedes Benz W204 Android Head unit, W204 Android Screen
Best 8" Mercedes-Benz C-Class W204 head unit upgrade factory looking Android screen with navigation system, Apple Carplay/Android auto, for Mercedes C300, C180, C200, C220, C230, C280, C300, C320, C350, C250.
