Erisin PX5,Android 9.0 Bluetooth issues - MTCD Android Head Units Q&A

Hi,
I was wondering if I could get some help with my issue. I bought an Erisin ES8049U head unit that I am trying to connect to my cars after market engine management system via Bluetooth. The head unit discovers the engine management system but it's quite troublesome to connect to it. Sometimes it connects, sometimes it doesnt. The Bluetooth connection to the cars engine management unit works fine from my Samsung mobile, so the problem is in the Erisin head unit.
Also when I finally get it to connect, no data comes through to the engine management system, it's like its not even connected and sometimes it flashes connected/disconnected.
Here are the info on the system:
PX5
Android 9
Build: rk3368-userdebug 9PQ2A. 190305.002 20191113.183229 test-keys
Kernel: 4.4.167
MCU: MTCE_LM_V3.43_1 / DEC 17.2019
CPU: Octa-core Cortex-A53 @ 1.5G
BT chip that has been selected in the system by default is: SD-8350
I've read some of the BT connectivity issues and they mostly have had different BT chips installed, at least originally. Any idea which chip I could test from the list, or is there a MCU that would fix connectivity issues? Or any other things I could do?

OK, I got it to show the data from the engine managament unit when I disabled Wireless and after that it started connecting. But if I restart the car, it doesnt want to connect to the application. With my phone it works flawlessly. I wonder if it's an application error or something to do with the head unit.

EONON G2110F or G2110ZV Firmware Update Caused RADIO and WIFI to be non operational

I need to restore the operation of my Radio and WIFI for my EONON 2110F after a Firmware Update. The Radio APP displays and responds to user input, but no sound, the WIFI fails authentication. Below are all the specifics that I thought would be helpful to anyone who could help.
I was told to update my firmware by the Manufacturer and now the Radio and the WIFI do not function. The Bluetooth and DVD function, but I can’t enable the Navigation without the WIFI, so the GPS is uncertain.
Any help would be appreciated

I purchased an EONON G2110F or G2110ZV Head Unit from EONON EBAY. There were a few issues I had with the Head Unit, some were my lack of understanding and 3 were the unit.
1-The Steering Wheel Control would not work reliably with my 2004 Honda Odyssey.
2-The Weather App was not finding the region I entered so it never updated.
3-I could not connect my music on my Apple iPod Touch to the Head Unit, the iPod is Model A1288 with IOS 4.2.1, although my iPhone 4 with IOS 7.2.1 music could be played.
These were minor issues compared what I am now dealing with the Head Unit.
Asking Support at EONON was very aggravating. They would not answer my questions correctly. Such as if I asked them about my problem connecting my iPod Music they would send me a video using an Android. If I asked them about the Weather App not working, they told me to perform an update without providing the files or instructions. If I asked them about wiring up the Remote Steering Wheel Control, they would send me a video showing someone with a phenolic perf board with buttons on it performing the remote control operations, with no wiring detail.
Any help would be appreciated
Just installed same unit myself today, will share info as I learn more...
Okay, everything spec. wise and operations-wise is on the Eonon site...

Now, I myself am running a custom Lollipop ROM on it, that's also got root access. Only thing I don't like about it? The notification bar on KitKat has an icon which switches the screen off, so making the car interior dark during night drives. I'm hoping to get a message to the custom ROM's developer, Malaysk, and ask him about including that feature in any new ROM he makes for the RK3188 800x480 head units, like ours.
To find out more about our unit, visit the Android Auto section here at XDA. Malaysk's ROM, and others, are available there.
g2110f in a bootlock
I had that same problem, and corrected it by holding the "HOME and POWER BUTTONS" together holding until you hear three beeps, release and short press the power button.
It booted to the system set up or recovery, Use the power button short press to scroll down to recovery and clear cache. Long press power button to start the recovery process.
When prompted finished, restart the unit. Mine booted up normally!!!!!!
You'll have to reset your clock and other operations.
Goodluck!

Sygav / Dasaita PX5 2019 Android 8.0 10.1inch Stereo Head Unit Issues

I just bought a new January 2019 Head Unit from Sygav China Took 8 days to arrive by USPS
This Unit for any Toyota Rav4 2013-2017
Manufacturer: Hot-Audio / Dasaita
Sold in US by: SYGAV via eBay
Sold in China by: Dasaita via Aliexpress
Pure Android 8.0 Oreo Operation System
- CPU Processor: Rockchip PX5 Octa-Core ,64-Bit Coretex A53
- RAM Space: SAMSUNG DDR3, 4GB
- Memory: 32GB
I have 4 questions.
The Factory Backup Camera on this Rav4 Hybrid 2017 is 1080p,
The firmware from this PX5 Unit only allows to display 420p for backing up display and not the true 1080p
The firmware from this unit as strange AM Radio increments and doesnt allow to show 1130AM
The firmware doesnt allow to install newly Google Playstore apps like Netflix
I was able to install Netflix older version 4.16 which i hate because on the New current Netflix Version, it allow you to download movies and tv shows to play and watch later when there is no wifi.
Is there a newer Firmware for this so its fixes the backup camera headunit software resolution
Is there a better radio software for the unit that has the am frequency fix so i can listen to the news and traffic radio report
Is there a Firmware that addresses and fixed Am radio frequency that allows people to manually input the channel by digits or find 1130am
Is there a Firmware that allows me to install the current new Netflix APK?
Is there a Firmware that allows me to set the display brightness to a higher brightness?
besides that above issues, This is really a huge upgrade from the Toyota factory HDradio that is a piece of **** and useless Entune.
This stereo sounds just as great as a Kenwood and Alpine new stereo, Sound is a Huge improvement and bettter bass.
Love the android features including able to set it the way i like and has a better GPS Map than Toyota **** hole Nav Maps.
I dont have any lag or pause issues, responds quickly with my apps APK
any help from the community here would be greatly helpful, its runs on the PX5 platform
love to know how to get 1130am, the FM and Am radio scan is terrible as it just passes all the high signal stations and cant seem to get 1130am , the slider is useless as it skips channels frequencies also .
Mal in Vancouver Canada
here is the unit i bought from Ebay, if anyone bought the same one and has the fix . the Ebay item is 202266435549

A-MEDIA AUTO MTCE_CHS_V3.76_1 Bluetooth Problem

HI all, I have a problem with Bluetooth on the following A-MEDIA AUTO head unit:
Model
PX6(1280x720)
Android version 10
Build number rk3399-userdebug 10 QQ2A.200305.004.A1 eng.hct.20210902163038 test-keys
Kernel version
4.19_111+
#158 Wed Aug 11 15:57:41 CST 2021
MCU version
MTCE_CHS_V3.76_1
May 13 2021 15:42:50
CPU
Dual-core Cortex-A72 @ 1.8G
Quad-core Cortex-A53 @ 1.5G
Memory
3841MB
I know Bluetooth problems appear to be legion on these Chinese head units, but maybe someone can help me sort this out. Now there is no problem pairing any device with a PIN: mobile phones and OBD2 dongles pair up just fine. But I have a lot of Bluetooth devices and applications that communicate directly - no pairing required - such as battery monitors, BMSs, mobile phone repeater units. These devices/applications used to work on my old Android 9 head unit (different chipset entirely), but now on this new Rockchip 3399 Android 10 unit, none of them can communicate at all.
I'm not sure if it's an Android 10 problem, or (more likely I suspect) a broken Bluetooth implementation in the MCU. Another problem is that audio pass-through from the mobile phone doesn't work at all, even though all other phone operations work as they should.
The Bluetooth driver setting in the unit is set to WQ_RF210. I've tried all of the other settings for fun, but of course there was no improvement.
Is anyone able to shed any light on this?

Help: Audi a3 with android head unit

Hello, all good people, professionals, beginners. I am Slovak for the introduction and therefore your language is not my natural so I apologize in advance. What i can't write, translate in google.
I have audi a3 12.2009 sportback gen2. My original radio 8P0035186P.
Air condition 8P0820043BH
Central electrics 8P0907279N
Gateway 1K0907951
Parking assitance 8P0919475B
Steering assistance 1K0909144C
Dashboard 8P0920931T
I buy android head unit px5 1024x600 rk3368 A10 octa core cortex-a53 2gb ram 32gb rom. (mtce_chs_v3.67_1 Nov 7 2020) (core 4.19.111+ Nov 23 2020) Canbus decoder CHS 20201201 A3/A4/TT HW:v3 SW:v1.
What works: steering wheel control, day / night mode change via sensor, battery/alt voltage - that is all. Used CANBUS protocol audi A3 simple 1/2 gen in factory settings.
I have the following problems and questions: The car does not communicate with the radio at all. Radio does not display vehicle management, applications or something for any communication between the vehicle and the unit. When I change the canbus protocol to golf7 or high class audi in factory settings, will be displayed after restart - vehicleapp and controlsettingsapp. When I run the application in canbus golf, turns on but everything is unavailable. As a layman i tried to pull the app from canbus golf7 to my audi a3 simple canbus and install. The application will install, but stop immediately. What I'm doing wrong or where I should look for a mistake according to you? Why I don't have these applications there at canbus a3 simple?
I called Audi support and I asked them supports my vehicle these things: Parking radar/assistant, open doors, air conditioning, tpms and more.. They said yes but only if you have rns-e radio. Rns-e dont have bluetooth and other good staff so i buy this and I am unhappy. I use obdeleven when I turn on a function, for example parking ilustration the function will disappear from my dashboard and for me logically sends the sensor control to the radio. But no and why? it's radio too waste or audi just can't do it? I will answer every question by attaching any file ask anything.

AndroidOS and CarPlay - BT Connection Disconnected After CarPlay Handshake

Hello Everyone,
I am a new AndroidOS user and recently had a friend help me install a head-unit to my Audi A4. The head-unit is similar to the following model:
Audi/Seat | Qualcomm 665| Android / iPhone | Octa Core | 6GB RAM &128GB ROM | Integrated 4G Solution | IQ82A4AL
XTRONS IQ82A4AL is a brand new Octa-core car sereo for Audi/Seat with Qualcomm 665 6GB RAM 128GB ROM Integrated 4G solution plus the latest in-car entertainment features premium quality built-in DSP, CarPlay & Android Auto and more.
xtrons.com
Background:
I have noticed that when I INITIALLY pair my iPhone to the Android head-unit over BT, it will ask me to pair on my iPhone (which I confirm), and then switch to CarPlay automatically. At this point everything dealing with CarPlay is handled over Wifi (not BT), but if I go back to the main AndroidOS UI, and check if my BT is still paired, is it DISCONNECTED. I am also able to confirm that the BT connection is disconnected on my iPhone as well. Each subsequent connection, as soon as I turn on the car and it connects to my phone (over BT), it switches to CarPlay, and then the BT disconnects. I would have assumed the BT connection would still be active and paired at this point.
Question:
Is the BT connection being disconnected (after CarPlay is initialized) expected behavior? I chatted with my friend who is an Android-Auto user, and he said with his setup (using similar head-unit), the BT connection is ACTIVE even after Android Auto takes over control.
Any feedback on how this is supposed to work for Apple iPhone users, utilizing the CarPlay functionality, would be greatly appreciated. If I could provide any additional information on my side, to assist with troubleshooting, please let me know.
Thanks,
Asif
