PX30 Android 10 Unit - Mode key sequence change - MTCD Android Head Units General

Hello
I just bought a new car with an Android PX30 unit preinstalled.
Although there is an app which can help assign function on wheel keys (Key Study) this cannot allow me to change the apps launch sequence when I press the "Mode" button.
How can I set up my own sequence on this button?
Is there any way?
Please help.

Is it an MTCD unit

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

Or here there is no reaction on volume up (please excuse my loud breathing)

Key study menu doesn't work at all:

Here is magic volume up (you will also see a handsome gangster guy)

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.

Unable to setup on DASAITA PX6, CarPlay steering wheel phone functions buttons

Hello guys:
I am not able to setup the control wheel steering buttons for Phone functions ( pick up a call or end a call) on a DASAITA PX6 10.
On settings I selected CAN BUS
I setup the following commands:
- Increase/decrease Volume---OK
- Mode ( to swap between radio, AV, iPod...)---OK
- Next and previous song---OK
but when I setup the phone setting it is configured but on CarPlay doesn't work, I am no able to pick up the phone.
Any help???
Best regards
What does reseller suggest when contacted for support
My understanding is that there are two ways to connect these units to can bus.
One is with the external vehicle specific can bus boxes, which are not really programmable.
The second is with the key1/2 wires which is internal and are programmable through the key study. I have never used this method, so I know nothing about it... but you could try it.
If all else fails, you can try a PAC can bus adapter.

Thanks for your replies.
I can program the keys. But what I am not able to program the phone function to work. I assign the functions to the buttons but it doesn’t do anything.
On the other hand the other buttons programmed (increase/decrease volume) works properly

Did you setup the keys for just the Dasaita in the unit's settings, or have you also setup the keys in the ZLink app?
I had only done the former and had this problem when I first was trying CarPlay with the ZLink app. What you will need to do is open the ZLink App, without connecting your iPhone to the unit (put it in airplane mode, or leave it in the house far away from your car), then go to Settings within the app. There you will see options to assign the steering wheel keys to the various functions you want for your phone. Once it is all set, you will be able to control CarPlay exactly how you want.
Hope this helps!
