How to disable some steering wheel controls on PX5 - MTCB Android Head Units Q&A

Hi fellas!
I have a peugeot where i fitted a custom px5 android radio. Since i have a faulty button on my steering wheel which triggers the "recent apps" function on android randomly i'm trying to disable that command via software. Is it possible? How can i do that?
It's pretty annoying and i'm already looking to change the button, but untill then i have to find a solution to this problem.

Canbus steering wheel control buttons for media next/prev

Guys i have a MTCD Malaysk 8.0 (i think HA alhough i've crossflashed a few times so forgot exactly) and i have a raise canbus for my golf, how can i make my golf steering wheel buttons work in headunit, spotify etc, they work in the stock BT app, the keycodes according to MTCD tools is 300/299 but even when settings them to media_next/media_prev it doesn't work.
mtcd tools or rk3188 app from the play store.
I'm having the same problem, I can turn the volume up and down. My unit has android auto, it's really annoying I can't skip tracks with my steering wheel controls. I'm not sure what am I supposed to do with the apps someone commented above. Were you able to fix this?
Me too. I'm a premium member of Spotify but end up using my lame stock music because of this problem.

How does steering controls works?

Hi,
I have a MTCE / PX5 with a raise , ford focus 2012 canbus decoder. Steering controls work (vol up/dw next/prev/play/pause ONLY) BUT how come I can't see anything in wheelkey study app? I would like to rebind some of my steering controls but the app don't see anything.
I have so many controls on my steering wheel I would like to bind but I can't!
Please someone have an idea what's wrong?
Thanks!

I’ve wondered the same, I believe you need to use the mtcde app to make changes to already default binded buttons but not worked out how to unbind one first.

My understanding (although haven't tested it yet) is that you need to connect the cables Key-1 and Key-2 directly to your steering wheel if you want to use the default learning function. This is assuming Ford Focus uses resistive bridges for steering wheel keys (Mazda does). You'll have to get & check a Wiring Diagram specific to your car to find the right cables. Also, Key 2 is NOT ground, you have 2 cables because sometimes the steering wheel controls go to different devices (in Mazda 3, the Vol +/-, Next and Mode go to the stereo, while the Push-to-talk, Hang-up / Hang-down go to the Bluetooth controller)
Hope this helps
Having said this, maybe you're better of by testing first XPosed, an app that allows you to change the functions of the keys. But you'll have to root your device. Malaysk has a SW release for PX5 already rooted and with XPOSED pre-installed. But most probably XPOSED will only let you change the functions of the keys that are already working, not to solve the issues with the ones that are not

I have the same problem on a Ford Kuga. Did you find a solution ?
Maybe the canbus configuration in the "settings" menu (the password protected menu) ?

The wheelkey study app is for non-canbus only.
The steering wheel keys are controlled by the canbus decoder for some vehicles. So that you can not program them.

Good response, but I think this thread went to crickets weeks ago.

Helpful -- thank you. Same issue here with a 2014 VW Beetle and an Eonon GA9153A (MTCE_HT_V2.84_1). At least now I understand why the wheelkey app doesn't recognize any steering wheel buttons. Bad software design -- the app should really show a message explaining this better

Android car interface box, am I in the right place?

I bought one of these Android car computers and I'm not sure which forum this belongs to. I'm in the MTCD forum because I noticed the post about ZLink and in the "Factory Settings" menu of this box there is a ZLink toggle. FWIW the Factory Setting on this unit can be accessed with 0000. My main question is which forum should I be posting to about this box, but the issue I'm looking to solve is that this box is connected to CANBus, but it's not supporting my steering wheel controls. There's an apk on it called CarCanBus.apk, I'm hoping to either modify and repack this, or install a separate CANbus app that can detect my button presses and translate them into keyboard presses.

Double click on button actions?

Since I don't have steering wheel buttons in my car and non of these units have buttons, or if they do have buttons it has smaller screen then a phone, I wonder if someone did come up with solution for the next track action to work by ie. double tapping home button?
I wonder if there are any bluetooth controllers that could be attached to the steering wheel or the dash. Then you program the unit what to do when they are clicked.
Google seems to find some.
Well from the search here it seems on of the BT controlers work with the MTC units

Problem with MTCE PX5 head unit related to steering wheel keys

Dear community,
I'm kind of lost since I get no support from Erisin about this (no response)
I have a BMW E46 from 2002 and the Erisin head unit.
MCU version is stock px5 MTCE (px5-userdebug 8.0.0. OPR5.170623.007 eng.hct.20180417.101726 test-keys)
I liked the idea of controlling the head unit volume by steering wheel.
Therefore I wired and installed the steering wheel buttons to my car.
The ACC works fine and in general I can control the head unit by the buttons.
Change Volume, Skip a song and so on...
Buuuut very often the head unit goes crazy or the control gets lost over the steering wheel buttons. (I am not able to drive over 30 minutes without having this error)
It seems like the head unit receives some ghost commands and volume goes up to max or I have random song skips. Sometimes it simply doesn't react on buttons.
Of couse this is not usable at all, therefore I disconnected the whole buttons.
For example you see a ghost volume up at 0:27
https://youtu.be/h5rCFSF8pew
Or here there is no reaction on volume up (please excuse my loud breathing)
https://youtu.be/e53De2HQJfY
Key study menu doesn't work at all:

Here is magic volume up (you will also see a handsome gangster guy)
https://youtu.be/ZPDQMeU4CNU
I have no clue how to debug or what I can do.
Any hints from the experts?

You should go Settings/Steering wheel keys to program the SWC, but not go to panel keys study.
I think the key menu doesnt matter. Actually the Buttons work as expected. But it gets out of control very often (random skips, volume up and so on). I also saw a key menu where I See the logs of key press. The head unit seem to actually receive the ghost key strokes repeatedly.
Have you tried entering at the factory menu and changing the car model at canbus menu?
You have a full menu for the keys where to change configurations.
