I recently purchased an Android 11 (PX6 based) head unit from Pumpkin and installed it. After the installation I discovered that making / receiving calls via Bluetooth results in no audio from the head unit. (I've tried with 3 different phones) Bluetooth audio works fine for music / apps, regular audio on the device works fine as well.
Does anyone have any ideas as to what I can do to resolve this? So far Pumpkin's support has been unable to offer any suggestions.
MCU Version: MTCH_HT_V3.82_1 - Oct 27 2021 11:01:18
Build Number: rk3399-userdebug 11 RQ3A.210705.001 eng.hct2.20220118.090809 release-keys
Kernel version: 4.19.193 #240 Tue Jan 11 11:23:57 CST 2022
Android Security update: July 5, 2021
Google Play system update: Feb 1, 2021
The "Bluetooth" app on the device shows its version as 1.0
The Bluetooth chip selected in the options is: SD-816
Pairing seems to work, and I can hang up, dial, change from device speaker to bluetooth, etc I just get no audio coming through.
I received a firmware update from Pumpkin and am now at:
MCU Version: MTCH_HT_V3.82_1 - Oct 27 2021 11:01:18

However there was no improvement. I still have no audio from the Bluetooth Cell Phone portion.
I resolved this problem. It is not a problem with the head unit or its firmware / software. It is important to note that the radio only outputs the phone audio on the FRONT channel speaker outputs.
The unit is installed in a 2008 Jeep Wrangler, with an OEM amplifier system. On those amplifier systems, Chrysler reversed the front and rear input wires in the wiring harness. The factory installed Jeep audio amp only outputs audio from what it receives on the "Front" input channels. With the wiring reversed, the OEM amp was actually receiving "REAR" audio from the head unit, not "FRONT" audio. Thus no sound from the cell phone output.
My solution, was reverse the connections for Front and Rear speakers.
I do you have the file of the mcu update?
Hallo, i need the MCU file MTCH_HT_V3.82_1.
Can you send it me please.

Hello everybody.
I have been scouring the Internet and I searched these threads and I am still coming up empty. I can't map volume up/down or next/previous track. There are a few other bugs but this one is driving me crazy. I am wondering if the seller (Seicane) sent canbus with wrong pin-out. I have a 2010 f150, SYNC, and an Android head unit with these specs:
Model Number M222
Android Version 4.4.4
Kernel Version 3.0.36+ [email protected] #24 Sat Apr 9 11:11:37 CST 2016
Canbus version F150 V1.03.001BP
Canbus Connect Connect Success
DVD version 3200
App Version Part9 2015-10-20 15:25
Flash Version A006
Mcu Version 01604080.A
Build Number rk3188-eng 4.4.4 KTU84Q eng.rks 160.20160409.153223.WQ.TP000.i0
Has anyone had this issue? And a resolution?
Canbus Integration Issue - 2010 Ford F150
Chip, I am experiencing the same problem as you with my Canbus not completely integrating with my 2010 Ford F150. Have you found a solution to your problem, and if so, do you mind sharing them with me?
based on the Model number "M222" seems like it is probably Seicane selling a RoadNavi.com unit. The S160, but for a Ford.
probably this guy:
http://www.roadnavi.com/product/m222-ford-f150-media-satnav-2009-14/
their forum is fairly active:
https://www.roadnav.com/
I would try that and/or e-mail their support. I found them to be very responsive

Sorry, I missed this. I have not found a solution. I do not believe it is solvable through software, I think they sent the wrong canbus. I am about to ditch the whole thing and chalk it up as a bad experience and go with one of the Android Auto units. If JBL's cp 100 would have been released on time it would be in my truck now. Sony has announced an affordable unit, it also is not shipping yet.
Hi everyone,
I have bought a Android headunit from aliexpress for my mercedes B-klass W245 which is a full replacement and looks factory.
The unit is really nice, but i have a few small problems and the seller is not replying anymore.
It runs on Android auto 7.1.2
This is what is days in the info screen:
Model: PX3 (1024x600 S)
Android version: 7.1.2
Security patch: 5 may 2017
Kernel version: 3.0.101+ [email protected] #806 Mon oct 16 11:32:44 CST 2017
Build number: px3-userdebug 7.1.2 NHG47L eng.hct.20171018.184623 test-keys
MCU version: MTCE_CHS_V2.65_1 Sep 15 2017 11:43:18
CPU: ARM [email protected] (x4)
Memory 2048MB
Now the problems i have are the following:
- Radio sound is much louder then all the other, like A2DP. I have installed TomTom from the app store, and the sound level is the same as A2DP which is much softer then the radio. Something i can live with, but still anoying sometimes.
- Sometimes the Bleutooth hangs or just does not want to connect. hard restart from unit is neccesary
- People who call me hear them selfs echo. I do have a external MIC attached to the unit. (would be awesome if i could connect the mic that is alreacy in the car from factory.)
- and last one, i have a reverse camera, which i had to mount up side down, is ther a why in the software to flip that screen?
I think some of these might be solved with a software upgrade, or maybe even upgrade to 8.0 if possible? But i do not know what brand headunit i have...
Hope you guys can help
Nobody?
Well, Hyundai Elantra 2013 same unit as yours.
Same issues except Bluetooth!
I have tried replacing the mic. I purchased the unit through seicane and they sent me an "enhanced" model. Same issues.
Hopefully someone replies, subscribing to this thread in hopes!

Is there a ROM / software update available?
I have, from the beginning, some problems with the sound.
When I listen to the radio or music via USB stick it goes well.
As soon as I watch a DVD or use the Google Maps route planner, and from there
I use the sound, all the sound is gone. Including the touch clicks.
Then I have to turn off the entire unit without power to get the sound of radio and usb back.
Kind regards

Hi all,
Just recently purchased this unit: EINCAR Android 10 single din (Model no on the box is HTT-AD9505) I would post a link but can't due to my post count!
The sole purpose of having the unit is for me to be able to view live data from my ECU via an app connected to the bluetooth module on the ECU. My issue is that I can only seem to connect to phones. The settings don't have the usual bluetooth settings options I am used to seeing in android settings, the only place you can access anything bluetooth related is in the units music or phone app. Is this likely to be by design with the firmware? Can I change the firmware to something different that can attach to any old bluetooth device?
The units about device page has the following info:
Android Version: 10
Hardware Info: Quad Core AllWinner - ROM 32GB - DDR3 1GB - 1024x600 - b2
Kernel Version: Linux 3.10.65 - Wed Jan 8 111:19:29 CST 2020
OS Version: HTTC0101-N78-2.4.4.3.12 - IVT - 200108
MCU Version: STM8-20200316-74-HHT-32
BT Version: 3A03
The app I am using is VEMs Display (vems.hu/android/) and the bluetooth device is communicating serial over bluetooth.
Thanks in advance for any help
After trying to install and run Bluetooth scanners, I now realize that the unit is blocking anything that isn’t the pre-installed bloatware from accessing Bluetooth. I now feel I have a giant paper weight!

we have same situation with same car radio and same BT problem, i ask everywhere without a valid answer.
maybe the only difference from us are:
2gb/32gb (instead 1/32in your device)
mcu: stm8-2019 (instead your 2020 in your device)
and maybe something else
