Xtron TB706PL mcu issues?

Hi all, hoping someone is able to help with the below issue.
Have a Xtron TB706PL, currently the volume up button is not working.
All other buttons work fine, pressing the Reset button briefly mutes the unit on/off, long press resets the unit.
The unit was working fine when I first picked it up, but bluetooth was not working in terms of finding devices.
Did a dmcu.cfg update using the file from the link below, and the problem with the volume button began after that. Unfortunately I did not back up the system dmcu.cfg correctly as I saved it to flash instead of GPS (SD Card) before the change.
Managed to get the bluetooth finding devices though.
Any way of getting the factory dmcu.cfg?
Is that most likely the issue?

Running Android 6.0.1
MCU Version MTCE_GS_V2.84_1
Cheers,

Have you tried assigning button in factory settings?

Thanks marchnz for the reply.
I believe I have got the correct process, but could be doing something wrong.
I have gone to factory settings and reset the key panel, then when I go to key panel study, pressing any of the four input keys does nothing at all, as if it doesn't register the press. Nothing appears on the screen to allocate the function for the key. I have seen other people's videos on how this is meant to work but doesn't for me.

As a new member, can't link any think yet.

Touch-screen calibration and touch button program for PX5
(Be sure to touch the "red" mark!, I did it backwards messing around and caused my touch input to be all inverted)
Try this, I did the same thing on my Dasaita unit.
Note: (at least for my unit) don't program longpress function...it won't take it and thus default you back to square one (no working panel buttons)
Hope this helps

Guys, thanks for the help and advice!!!
Doing what Hkw84 advised resolved the issue, video made things clear.
I was using panel key study in trying to setup the keys and not the touch key study which makes complete sense now as the keys on my unit a touch sensitive like the screen...doh
Appreciate the help, deciding if i should upgrade to malaysk Android 8 now
Cheers,

Is it possible to change the way the wheel controls work on MTCD (GS PX5 Oreo)?

Can anyone advise on how I could ho about changing the list of apps that gets started by the Mode function on my Xtrons unit (MTCD GS PX5 oreo)?
I know someone has done something similar with a Joying unit, but as far as I can see, they replaced the "Sofia-1-C9-Server... apk) with an alternative version.
I've pulled all the system apps to my PC via ADB (root) via WiFi, and I can see apps like MTCControlSettings.apk and MTCContolInfo.apk but there are no apks with "server" in their name
So I'm not sure where to start looking for the APK which handles the steering wheel control "Mode" handling.
Does anyone know how this is handled ?

are you able to resolve it? im having the same problem. btw my unit is a MTCE_CSN thanks

I've not had time to investigate this.
For the moment, I've just set my Mode button to be the Home button, as thats better the cycling through a load of useless "modes" like the AV input and their useless audio and video players.
I did try to work out how the radio communicated with the system apps, but I'm having a lot of difficulty de-odex'ing (decompiling) even the radio app. Because the apps are Oreo versions, and most of the decompilers don't fully support Oreo odex (compiled application program) files
I did post a question to the general Dev part of XDA about de-odex'ing Oreo files but didnt get any responses

I would be interested in this if you figure it it out as I'd like to get dab in the list of apps it cycles through.

That would be enough for me, but with onboard apps or settings i haven't found a way to change it. I can use my Wheel control for changing volume and skipping music in any music app I am using, but the mode button always switches throug radio, ac input, mediaplayer and dvd.
The app for steering wheel control which was preinstalled on my head unit, doesn't react to any button and the firmware settings only to the hardware buttons of my head unit.
So, how did you do it?

In the Settings, ( think its in the Car) section, is the setting (app) which allows you to associate specific steering wheel buttons with specific actions.
I thought all generic units had this app, because the steering wheel button for each car operate differently.
My Subaru only has one wire from the steering wheel, and has 6 buttons. Each button has a different electrical resistance, and you have to press each button, and then associate a Short Press and a Long Press, on that button, to a specific action.
The controls like Volume + and - and Track + and - and Mute are pretty standard.
The only other button I have is the Mode button, and I assigned that to the "Mode" action in the settings. However the Mode operation, cycles though a predefined list.
So I simply reassigned the Mode button to the Home action.
I did try a few other things, like seeing if I could press 2 buttons at the same time e.g Mode and Track +, but it either treated this as a press on the Mode button or a press on the Track + button. So that didn't work.
If I get time, I'll have another go at decompiling the system apps, but last time I tried to do that, I could not see anything that looked like the list of apps.
If I had programmed it, I'd probably put the app names into a string resource, but goodness knows what the programmed did who wrote the system apps in these units.

Thanks for the quick reply. I already tried the factory settings but my steering wheel buttons won't work there. I only can set action to the buttons on my radio. Sadly I have to wait for any other solution. But thanks again for sharing your experience :good:

What brand and model of HU do you have?

Hey,
Opel/Vaux/Chevy cars have canbus hard mapped buttons.
Mine can't be configured through the in-built apps or factory settings either.
One would have to examine the canbus.apk / MTCManager to maybe update the xposed for MTCDTools.
MTCD Tools can see the button codes (3 digits), but can't map any other function or even intercept.

I have a Xtrons PB78QSFP-B which is designed for a Ford Focus and came with a standard canbus adapter for ford. But I have the old model of the HU which has only 2GB Ram not 4.
My guess is, that Ford has hard mapped buttons too, like Xorit said it about Opel/Vaux etc

update guys! mtcdtools will do the trick! though the old mapping will flicker but still the newly assigned actions will prevail.
i can live with this already. maybe ill just find the solution to delete the factory set MODE actions :laugh:

Did your have to root your unit or install anything like Xposed etc? Or does it just work with the stock firmware?

works with stock fw. im not yet doing any firmware mods

No option to program "long click" for steering wheel buttons?

I have a PX6 4/64 GB head unit.
When programming steering wheel buttons I only get the option to program "short click". I can't find any options for "long click". In the screenshots from Hal9k it looks like short click and long clock would be displayed at the same screen.
As default I had SWC chosen in factory settings, but then only volume buttons worked. So I changed to CanKey, and now all the buttons work, but I can't chose and option for long click. I have the same problem on stock and custom ROMs. I have tried different CanBus profiles for my car in factory settings, but the default one is the only one that seems to work okay.
Is there something I can try to make long clicks work, or is it just not supported by my car? Couldn't find much information with a search on these forums.

Is the car a BMW? Sounds like the problems I have

No, it's a Mercedes-Benz. Maybe something with german cars?

Same problem for me for a 2010 Jeep Grand Cherokee (built under Merceds not FCA).

In Malaysk ROM full version (don't know about free) there is an option for programming double press of steering wheel buttons. I tried it and it works very well. Unfortunately I had other problems with that ROM so I can not use it.

Question Remap TEYES T-Pro Steering wheel buttons

Hey guys. About a year ago I installed a Teyes T-Pro in my '14 Focus ST, and while its better than the ST1 radio I had with a 4" screen, I hate this thing. An entire 1 inch vertical segment of the screen does not work, the screen does not turn on when the ambient temp is below 50 degrees F (until it heats itself up, takes like 25+ min in winter), subwoofer pre out doesn't work, and many many more stupid issues.
The reason I'm posting, though, is I would like to remap one of the steering wheel keys. The built in app to do this, of course, does nothing. Apps like button remapper also do nothing, probably bc the buttons function over CAN-Bus. When I press the microphone button on my steering wheel it opens an app called "car-info" which also does almost nothing. I am wondering if there is a way to have another app (google assistant) open right after this "Car-info" app opens. Also, if anyone has any experience with the T-Pro any input would be very appreciated. TEYES Tech support never responded to my multiple messages, of course, and I can't seem to find a head unit that sucks less and I don't want to roll the dice on another Teyes product.
Any input would be greatly appreciated...
Thanks a ton

Anyone got anything?

Contact TEYESAustralia, Hopefully they can give you a solution

What kind of car do you have (year, make, model, etc)?
Did you install the T-Pro yourself?
Do you have schematics for your car? If so, how do your steering wheel buttons connect to the old head unit?
Can you tell from the schematics if the buttons are resistive or not? Only resistive buttons can be remapped.
If your SWC are resistive, then you should be able to directly connect those buttons to the T-Pro inputs...I believe they are labelled key1 and key2. If the SWC are not resistive, I don't believe there is anything you can do about remapping them.

[Help] Assign button to app on MTCE PX5

Hello everyone.
I could not find a MTCE section and was unsure where to post, so I am posting this to the MTCD/MTCB/Android Head-Units threads. Sorry mods, please close or merge as you see fit.
I have a PX5 running Android 10. MCU version is MTCE_HXD_V3.62e_1 and would like to assign a phisical button (preferably a steering wheel button) to open TorquePro.
I found the remap function on factory options, but there are two problems with this:
First, only the volume buttons on my steering wheel show up on the buttons list, and not the "mode" button I wanted to use for this. Maybe this has something to do with CAN-Bus configurations? Or should I reset and map the buttons manually in order for them to show up? I think they all work. This "mode" button I don't use currently cycles between radio, media player and DVD and the skip track buttons also function as supposed, although being absent from the list.
Second, even if I forget about the steering wheel and try to map it to one of the buttons on the unit itself (like the DVD button I don't use) I can only map preset functions, like navigation, DVD, mute, etc. and not individual apps.
So I need either a third-party app that allows me to map Torque to a button, or a way to add torque to the mapable funcions on the factory options.
Any thougts on how to do this?
BTW, I tried MTCDtools but it doesn't seem to work. All I get from it is a "app keeps crashing" error message.
Thank you all!

Yes mtcE is an mtcD type. So you're in the right place.

All right, one step in the right direction. Yet MTCDtools didn't work. I installed the APK and it doesn't even open, all I get is a crashed app error message everytime I try starting it...
Any ideas what is going wrong here?

Have you tried the modified version 1.10, from AirOne70? #493

Not yet, just the one from f1x's GitHub. Will try it today. Thank you.

I have tried it, and it worked, so thank you!
Although it was just a partial success. I have a "source" button on my steering wheem which is used to cycle through radio/DVD/media player/etc. and managed to make it open Torque, like I wanted. The problem is that it also mantains the original function, so it launches Torque AND changes the media source on the same time.
I guess I need to "disconnect" the original functio. Any ideas on how to do this?
Thank you!

Unfortunately, I can't help you with that, try reading the thread, maybe someone has already solved it.
