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:

HI All,
im trying to make my steering wheel controls working my mkV 2009 Jetta SE. i retrofitted the steering wheel and as far as i can tell its coded correctly to the car.
however only one side of the steering wheel controls work with the android head unit. (the volume, and mute buttons). ive tried to set it up using the steering wheels control app and it doesn't seem to detect it.
At this point im not sure if its a canbus decoder error, a software issue or the coding of the wheel to the car.
does anyone with a mkV jetta have this working?
attached pics of the wheel and the canbus decoder which seems to be an RZ-07 by Raise.
any ideas?

Hello
You can check in factory setting, that You have set canbus for you car. If you set and it will not help, You can use:

Have you updated your mcu to the latest one? If not yet, do it!
Ps: these cheapest canbus comes with the hu are not so perfect (one click sys and that's it!) , but the pac one is much much better and re-programmable.. unfortunately is expensive one!

It is not the matter of any canbus decoder. The problem is inside MCU. Data sent from cabus decoder are received by MCU, then MCU through a serial port sends it to the MTCManager. It is 7 bytes frame, two last bytes are key code (unsigned short). MTCManager simply creates an intent, puts a key code and sends the intent through the broadcast.
Actually, MCU sends two types of key codes - irKey and HCTKey. HCT key codes are used in case of learning procedure (by factory settings app or by SWC Wheel app). Type of the key code depends on parameter rpt_key_mode (possible values are normal or key) set to the MCU via AudioManager. Learned key codes are stored in MCU - it is done by setting of the cfg_key parameter via AudioManager. For some reason, MCU sends HCT codes only for particular keys. It means that you are not able to change action of some SWC keys or panel keys, and some just simply do not work.
As you can see above - solution for the key codes done by the manufacturer is one big crap. AudioManager as an "communication bridge" with MCU - what the hell AudioManager has got to do with key codes ?
If some key codes do not work, it won't work until manufacturer (NOT THE RESELLER) fix this. And probably manufacturer will not fix this because no one know who is the manufacturer . Joying, Xtrons, Erisin and others are just resellers, they do not have access to the source code, so asking them for the fix is useless. It does not matter if you will buy an HU from Joying or from Xtrons - it will have the same bugs.

Actually it is done by "Pannel Key Study" in Factory Settings. Factory Settings app read the value of this parameter, parse it and display on the screen as an icons grid. There is nothing to do with the "raw" value.
Edit:
Anyway, if you want to play with some "reverse engineering", some time ago I prepared an app to read data from serial port, lookup the keys broadcast and audio manager parameters.
Go to the "Lookup broadcast", press keys that do not work for you, and let me know if some digits appears on the screen.
If no, go to the "Set audio parameter" and type rpt_key_mode=key, then tap on set parameter. Then go to the "Lookup broadcast" and press keys that do not work for you once again, and let me know if some digits appears on the screen.
Afterwards set the rpt_key_mode=normal or just reset the device.

Mate,
Short story..
As you can read in my topic; bought xtrons.. that I xtrons not resented but the company one who sold the canbus to xtrons,
so why pac has no problems with the swc button at all then?
this means that PAC has a decent programmed the canbus decoder.. right?
with the PAC one you get no mcu file with it at all
Summary: buy a pac canbus

It is just an workaround. I suppose it is connected to the "key" wires. But why units for ~350$ need this?

You do not need this, because you do not need to read from the serial port. Just use "set audio parameters" and "lookup broadcast"

Thanks, I set the audio parameter to key and I only get data when I push the buttons on the radio: com.hct.key.study 9136 is the phone hang up button for instance.
The steering wheel buttons report nothing, even the ones that work now (volume and mute)

It means that irKey codes are hardcoded inside the MCU. There is no possibility to override/learn them. You just have to wait for the fix from the manufacturer (if any will be released).

Hi there,
after struggling around with the mcte utils settings.ini file to remap buttons, I tought I might share what I learned.
This assumes, you have installed xposed, activated the mtce-utils module and placed the settings.ini file at your internal sc card (/storage/emulated/0).
Here's how to remap buttons:
PHP:
[android.microntek.service#keys]
# In this section, you have to put all GLOABL remap functions into. You can use the following ways or remapping:
# note: xxx always stands for the mtc-keycode. If you do not know them, you can use MTCD Tools -> Creata new bnding -> Obtain key sequence to get the key codes.
app_xxx=com.spotifiy.music
#--> this defines to launch any app, e.g. app_257 would in my case launch spotify when pressig OK button.
keycode_xxx = 4
# ---> with the keycode command, you can assign android keycodes. For example "4" is the back button, "87" is media next.
# a full list of android codes can be found here: https://android.googlesource.com/platform/frameworks/native/+/master/include/android/keycodes.h
activity_xxx = com.zoulou.dab/com.zoulou.dab.MainActivity
# --> this is to launch any activity. Always put a pair of app/activity with a slash in between. My example starts the DAB App.
intent_xxx= [any android intent action]
#--> this is to assign an intent. Couldn't test it yet.
keymtc_xxx= yyy
# --> this is used to reassign another mtc key.
[com.microntek.radio#keys]
# to remap buttons within specific apps, create an extra section which contains the app name [B][app.name#keys][/B]
# same as with global remapping, put the codes here as you which to reassign keys within special apps.
Well hope that makes the settings more clear for you.

I just made some small corrections to the above post and want to share my settings with you:
What did I actually do?
I changed the two steering wheel keys "Mode" and "List" to Keycodes 219 and 4. 219 launches Google Assitant, 4 is to go back. This way, I can easily launch Google Assistand for calls, navigation and spotify, tunein and can minimize if needed.
I assigned keycodes 87/88 to both forward/backwards keys, so that I in most apps can go forward/backward
I assigned my favorite apps to the buttons 1-6, which are DAB, TuneIn, Spofity, FM Radio app, Google Maps and Bluetooth Phone
So I can switch easily between all those apps. As the radio app has its own buttons assigned, here the keys 1-6 are still used as usual.
What doesn't work is the part where I wanted to fix wrong forward/backward keys in radio app. Assigning backward to forward and vice versa leads to a crashing radio app (behaves like non ending loop then)
PHP:
[android.microntek.service#keys]
activity_331=com.zoulou.dab/com.zoulou.dab.activity.MainActivity
keycode_365=4
keycode_276=87
keycode_278=88
keycode_256=219
activity_283=com.zoulou.dab/com.zoulou.dab.activity.MainActivity
app_284=tunein.player
activity_285=com.spotify.music/com.spotify.music.MainActivity
activity_286=com.microntek.radio/com.microntek.radio.MainActivity
app_287=com.google.android.apps.maps
app_288=com.hb.dialer.free
[com.microntek.radio#keys]
keycode_276=90
keycode_278=89
activity_331=com.zoulou.dab/com.zoulou.dab.MainActivity
Hope this helps!

Did you reboot after changing the settings.ini? This is needed. Have you also activated the xposed-mtce-utils module? And checked whether the mtce key codes used are the right ones?

hello, Any news ?
Thank you very much for this! I was able to figure out how to remap most of the keys on my CAN bus steering wheel controls. I'm now trying to figure out how to find an apps key codes so I can assign them to other keys on the head unit... How did you find out what the key codes are for your DAB key codes in the very last section of the settings.ini?
I have 2 apps I'm trying to figure out. One I'm trying to do is the FM radio app; [com.microntek.music#keys] and would like to make to when I press and hold the "next or previous" buttons that changes the presets, then just a single press will seek the next FM station. Do you know if there is any command lines that can be added to make it use the press and hold of a button? So that a single button can do 2 actions? I've played around with some of the units key study that has the ability to change the units buttons and can assign a single press, and press and hold, but the list of keys that can be assigned is limited.
The other I need to figure out is one button in a special app that tells it's special USB to send a signal to turn on the factory DSP amplifier. That app has button within the app that can manually send the signal, but I can't figure out how to find it's key code. And there is no Activity for it that I can use that I can find. I use an app called QuickShortcutMaker to identify an apps Activities name that it has.
Thanks.

--> activity_331=com.zoulou.dab/com.zoulou.dab.MainActivity
The keycode from the key I want to assign can be obtained my "mtcd key tool" or in hal9k rom, where you can activate that keycodes are displayed by key press. In my case, key 331 is the "1"-key from my orginal radio.
the app/activity combination can by obtained by the app "package name viewer" that lists you app names / activities of your insalled apps.
I do not know, how you can change behaviour between short and long press.
Also, how to change the behaviour of the keys within an app, is difficult. You can work with Intents, but I am not used to it.

@gforums or anyone with the answer, has anybody been able to remap a wireless keyboard/remote? Mainly I'm trying to get the volume and mute to work. I know that the volume is controlled by the MCU and the remote want's to control the media volume which does nothing on our units. I'm just not quite sure how it should be written for the mtce-utils .ini file.
MCU volume up/down codes for MTCE are: 273/281 respectively. And the remote/native android codes for volume up/down are: 24/25 respectively.
has anyone already tried get this running on android 9 (PX5)?
As xposed is needed and in android 9, xposed only can be installed as magisk module, I can't get it working.
So currently I do not know a way to change canbus keys in Android 9.
Anyone of you does?
Best regards,
Christian
Hi,
I'm running android 9, I installed Xposed, but how do you instal mtce-utils ? Can't find them anywhere.
Thanks
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.

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.
I've installed MTCE_GS_V3.01_3 head unit, and while steering wheel buttons work fine, the central panel buttons are no go.
I'm certain I've connected every cable that was connected on the original installation.
I've seen some suggestions on youtube to reset the panel button list, and then choose key study to add all buttons anew, however that does not help.
Right now Can bus type is set to 55 GM Simple, and that's probably the only one that works with steering wheel buttons.
I've tried changing knob type and other settings to no avail - I do full restart after the change, but when in key study no button press makes a difference.
Are there any suggestions what other settings should I try changing, or is there a way to check if a buttons press sends any signal at all?
You seem to be mixing/confusing steering wheel key assignment with the touch key assignments. These are two very different things. Canbus has nothing to do with the touch keys.
There is a touch sound setting that will cause the unit to beep every time one of the touch keys are touched. Please have a look at my instructional tutorial on how to set the touch keys:

This thread is not asking how to reset the touch buttons down the side of the panel screen. First go to Settings... Car.. Factory settings.. password 126 Then touch Key study category at the top Next Touch Key Study First the system will want...

I'm not sure we're talking about the same things, correct me if I'm wrong.
I'm talking about these buttons basically:

To my understanding (until now) they should be configured using Panel key study?

That looks like the control panel for the original radio.... and probably connected DIRECTLY to the original radio. Unless they operate through can bus, I don't think you can configure those.
I've seen them working on YouTube videos and such.
Agree with @Bob_Sanders on this. I was under the impression that it was just touch buttons off to one side of the head unit screen like many of these head units.
I suggest reaching out to the manufacturer of the radio with your question regarding the button panel.

Then it's possibly connected through can bus and you MIGHT get it working if you connect up your Key1 and Key2 wires and try the key study again.
I'm not sure if you have a can bus box on there already. If you do I'm not sure if you can run the box AND the key1/2 wiring at the same time. Try it though.

Can you clarify please what do you mean by "the box"?
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.
