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.
This multimedia knob change only the sound level of notifications. It's possible to make it work on MCU.
Thanks

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
Hi, i'm looking for universal head unit, with preferably latest HW, or px5 at least, that is 7" so I can stick matte screen "protector" on it.
What I can find is unit that still has hw button for next/skip song and volume knob (NOT volume +/- buttons). Or support BT remote that I can put on my steering wheel. I have old car with no resistivity based neither can steering wheel controls.
S far only unit I found that at least remotelly looks usable is some sony with android auto, but I kinda wanted to go with chinese android unit as I can have apps directly on it etc. Thought no next song HW button or buttons instad of knob for volume are really deal breaker.
I know modern cars are full of touchscreen so chinese manufacturers are probably going that way, well I have old car so I obviously don't like that
Anyway do you know of any chinese HU with form factor I would like or with working support for bluetooth steering wheel remote at least?
I've changed stock head unit to: px3/2gb ram/ android 7.1.2/ MTCDE_HZC device. (car: Opel Corsa D)
There is one strange problem: steering whell buttons working very quick, one push gives me two(often) or three(sometimes). For example i'm listening first song, push to button for next song it goes third song, (back button works same too) / or in radio jump too further station. Every buttons working like that, i'm pushing "mute" it's countinue with volume (in unit toasts says: mute on/mute off (very quick))
i've looked everywhere in settings but can't change (include factory settings). Am i missing something
(i hope i've explain, sorry for my poor English)
Anybody faced like that or any suggest?
I have a Honda CR-V and the five buttons on the steering wheel are properly received on my HU. Problem is, no matter what I assign to volume up, it will act the same as the volume down button. I cannot figure out why this is happening. I could understand if pressing volume up was being received as a volume down message, but that is not what is happening. Volume up is definitely received. But no matter what I set it to, it will just become a second volume down button.
Thoughts?
For which variant of headunit, MTCB, MTCD/E/P or other?
MTCD. Dasaita PX6
Hello!
I have a PX6 MTCE with a DSP that broke down. I finally got a new motherboard from the chinese seller and moved everything over to the new hardware. The new motherboard differs from the original one. The biggest difference is that they didn't send me one with a DSP.
The new setup is working. I had to remap the hardware buttons for NAV, BAND etc but found that easy to do in the settings. My only problem now is the left rotary encoder. It is working as "skipping" at the moment, i.e changing position in my song or podcast. The right knob works for volume. I want to have the left knob for volume and pressing the knob for power on/off.
How can I remap this?
My unit is rooted
Best regards,

Almost solved it myself. The solution was to install MTCD_Tools. With this app, I was able to figure out that I had to remap key code 299->281 and 300->273 With this info I found a way to remap in the settings of the Hal9k Mod firmware.
I still don't know how to remap long press on the volume knob to power on/off. I have the code for power on/off, but I don't know the current code for long press. I.e. Nothing shows up in MTCD_tools when I press the button at the moment.
