Hello all,
So I purchased a buttonless PX5:
https://www.aliexpress.com/item/And...32849648099.html?spm=a2g0s.9042311.0.0.qvQ36y
However, none of the Android widgets or volume buttons work to control the volume.
Only the little button off to the top right corner does anything.
I feel like I'm going to crash my car, constantly hunting for that thing.
Is there anyway to patch/hack this thing to respond to something like a virtual volume slider like this?

Thanks!
Why do you need onscreen volume? Didnt you have a CAN and steering wheel controls? The volume control on HU is not the same as on smartphones. It has controlled by MCU board where android board sends special commands from the headunit service.
My car came with a sport package, which meant smaller diameter steering wheel and therefore no wheel controls
That being said, the sound slider via settings menu is indeed able to control the volume via onscreen controls. It just doesn't seem to respond to the normal android media controls, is there a way to link the two together?
Then the simplest way is to use infrared remote control (if your HU has it) or to buy universal resistive SWC and connect it to Key-wires.

The only way is to create your own service or automation that will send volume control broadcast intents to mcu.
For my MTCB it may be even a shell commands:
Code:
am broadcast -a com.microntek.irkeyDown --ei keyCode XX
where XX - 19 (volume up) or 27 (volume down).
You need to find this commands for your MTCE here and you will be able to use Tasker for your own service creation.
The second way is to write service on java. But you need a skill for that.
Found xposed-mtce-utils do the job. It has "a strip of volume control at the bottom of the screen".

Thanks for the link! I'll definitely give this a shot.
Do you have any experience entering recovery mode on a deck that has absolutely no buttons?

Don't have a MTC unit but try this,
Install Terminal Emulator app, enter "reboot recovery"
pretty big fails on the trying front.
I've managed to buy a MTCE deck that has neither buttons or SD card slot with which to install malaysk rom the prescribed way.
Has anyone had luck with a pure download -> flash approach? If so, any instructions online?

I believe it must update from usb-flash drive.
Volume up/down codes for your MTCE: 273 and 281.
You can now use Tasker to draw your own Up/Down arrows and set the shell commands for them (w/root).
Or you can use any usb keyboard or other usb-hid device and set the volume commands for buttons you wish.

Volume control workaround on buttonless HU
Hi this should help you which I posted on Car Launcher thread.
Seems we have the same HU except mine was sold by XTRONS.
Like many of you on this forum, I love the simple efficient GUI of Car Launcher AG, amazing work from the developer ! yet I have come to the frustration of volume control on bare HU like mine : PE88CMPL from XTRONS which has absolutely zero buttons at all.
So I went on eBay and bought "Car steering wheel remote control buttons wireless android gps navigation", connected it to Key 1/Key 2, Ground and acc 12V.
Programmed the buttons to volume up down mute and other useful functions such as back/home/gps/answer call/hang up and shutdown.
These setups are in the Car Steering Wheel area in settings.
Those buttons are super small and come with a 3M double face on the back and can be properly installed on the console at arm/finger reach.
I saws that JOYING sells a larger one that fits in cups holder "JOYING SWC Steering Wheel Controller for Android Universal Car GPS Stereo Radio" if you prefer that design.
Enjoy
Hello, i now that issue isn't from this thread but i need some help for use an usb knob that dont make nothing on a MCU of Spreadtrum SC9853I.

you're in the wrong forum, suggest searching for "SC9853I" and ask the question of the knowledgeable joying people.
Hi. Sorry for my google english.
I have -Px6 DSP 9 " MTEC_CHS buttonless with Android Pie- and I couldn't find (if any) a "Knobby volume control style" apk for volume control. I can't put a link from Google Play.
The idea is to touch the screen with 3 fingers (anywhere on the screen) and rotate your wrist to bring up the volume control and increase or decrease the volume. Like a home amp. Do you know of any MTCE that has it since I suppose it should be integrated into the MCU or some apk ?.
Thank you all
I have a 2012 Mercedes GL350 with a MTCD PX5 head unit running Hal9 version 3. My steering wheel controls work for the standard phone answer, hangup, and music forward and back - but my steering wheel controls have a button that was used as a "wake" for the old head unit to listen to verbal commands. Currently this button does nothing with the new head unit. I am wondering if I can somehow set this to activate the google assistant to listen for commands. Currently if I try to use the "Hey Google" or "OK Google" voice commands both my phone and the head unit respond. I'd like to change the car head unit to activate on this steering wheel control instead.
Anyone have luck with something like this?
Similar issue here (Mercedes w164). I opened a thread for the can bus where you can participate.
Using the Hal9k ROM and set the option to display the steering wheel codes this button sends nothing. Therefore i assume it is related with the Canbus adapter .
hello
i have a px5 head unit,
when try to use stering whell buttons as long press (for eg. rewind music) its skips songs
any chance to fix it somehow ?
Running an avant4 avinusa bmw e39 unit, Android 9.0.
Probably a faq:
I’ve installed power amp, and want that to launch instead of the stock music player when hitting the music button. Power amp is working ok.
Don’t see a way to add new actions in button key study factory settings.
Don’t see a way to over-ride the behavior of the existing music action listed in the button key study.
Beyond that question, seems the builtin music app needs to be left running (background) in order for steering wheel button presses to trigger track forward/etc in power amp. How to fix to no longer need the default music app?
About app wheel key study I have HU PX5 rom malaysk 3.5 android 8. Can we add off the screen? I see some people can do it. When driving at night does not sting. When controlling the steering wheel So handy.
As picture https://ibb.co/qyb8Qg1 I see symbol X in mode factory setting , but in app wheel key without this.
:fingers-crossed:
