Thanks for your answers and again for providing us with the MTCE_MX_V3.41 MCU file!

Today I installed it on my PX5 Android 9 headunit (previous version was MTCE_MX2_V3.37_1) and it works without problems. The only difference I noticed so far are the car logos.

BTW, in the "about system" page, the MCU version is now shown as "MTCE_MX_V3.41_1" (similar to the V3.37_1 that I used before).

Do you know what the appendix "_1" stands for?

I have a WItson MX PX5 Unit that bluetooth doesnt work with Hal9k Android 9.

Any chances that using the stock would work?
[MTCD Software Development] ikerg:
If your bluetooth module is md725 (type2) then forget it to be working on android 9 either android 8.

No drivers are available for that systems.

It does not depend on the stock or custom roms

Solution to get a working SD-968 module in Android 9 for PX5

Here is the solution for all with a PX5 HU and SD-968 Bluetooth module where the Bluetooth does not work on Android 9.

Sympthom:

The Bluetooth App shows nothing in the name and PIN field and no Bluetooth devices are found

Solution:

1. Root the PX5 Head Unit

2. Download the attached zip-file and extract it

3. Download the ES File Explorer and install it

4. Open ES File Explorer and mount / as read/write

5. Copy the file "sdsdk968" to /system/bin/ and replace it.

6. Set permissions to 755 (rwx r-x r-x)

7. Mount / as read only

8. Reboot the HU

After this has been done, Bluetooth works again

I hope I was able to help some with the manual.

Hi everyone, I have some questions ...

1- My head unit is PX5 model "MTCE_MX_V3.00_1" with android 8.0, can I upgrade to this version of android 9 ??

2- I need to know what improvements are obtained when updating to android 9 ??

3- If I don't like something on android 9, or it works badly, can I downgrade to android 8 ??

Thanks in advance...
[MTCD Software Development] marchnz:
1 yes.

2. Nothing, larger number maybe; await for opposing responses claiming there is, based on some sort of subjective feeling. These devices are based on hacked chinese android containing bugs carried over to "updated versions"

3. Yes noting, validate via sdcard (validate this method works on your headunit) OR OTG. You might find a lack of posts on this subject on malaysk or Hal9k Kanged ROMs (modded factory ROMs)

Does MX2 have any advantage over MX?

From what I know both are the same, but MX has the advantage of built-in car logos which can be set as boot logo, which MX2 hasn't.
[MTCD Software Development] whitebait:
Sorry if this is a stupid question, but is the hct_px5_9.0 (20191216) ROM the same as the hct4 ROM of the same date?

I downloaded and installed the former (hct_px5 etc) and it doesn't have the day/night launcher etc.

I then installed the 20191125 version linked in this thread on Yandex and it's got the day/night launcher etc.

However, if the hct4 version from December is actually a slightly updated version of the ROM discussed in this thread, then is there a benefit to updating to that version?
[MTCD Software Development] whitebait:
Answered my own question. HCT4_PX5 is indeed a different rom to HCT_PX5. HCT4 one has the day/night launcher and seems to work fine. Having some issues with DAB-Z performance (especially using OMRI), which I didn't get with the original DAB app using the xtrons ROM.

Also, I noticed that within factory settings I now have a "DAB" options with 3 versions and no. Mine is set to "no" currently. Presumably this should only be set to 1, 2 or 3 if my head unit has a built-in DAB decoder rather than USB?
[MTCD Software Development] sieg01:
Hello,

"HCT4 one has the day/night launcher" Where can I change it ( day/ night )?
[MTCD Software Development] whitebait:
For me it's based on canbus (?) signal for headlights being on/off. Headlights on put it in night mode.

You can load the file from here:

[MTCD Software Development] chargeable:
As now i understand the chips comes empty from seller, does your file will work for different chip? mine at the moment is IVT-i145, and your files is for sd968 yes?
[MTCD Software Development] culjonito:
Unfortunately I only tested it with my SD968 chip. About other chips like the IVT-i145 I can't say anything.

I copied the file "sdsdk968" out of my working Android 8 installation from the folder "/system/bin/", then installed Android 9 on the Head Unit and copied/replaced the file back into the same folder.

So you could do this at your place, just with the file for your chip. Maybe it works...:

1. install Android 8 or a ROM on your Head Unit where your Bluetooth module still works

2. navigate with a file explorer to the folder "/system/bin/" and search for the file for your IVT-i145 chip. I can imagine that it is called sdivti145 or something similar.

3. copy this file to a USB stick or SD card

4. install Android 9 or a ROM where Bluetooth did not work before

5. copy the previously copied file into the directory "/system/bin/" and replace the existing one there

6. Set permissions to 755 (rwx r-x r-x)

7. Mount / as read only

8. Restart the Head Unit and test if Bluetooth is now working

In summary, you simply take the file for your Bluetooth chip from a working Android installation (earlier Android version) and copy it to the Android installation where the Bluetooth module does not work and the name and PIN is not displayed in the Bluetooth app.

If this solution also works with your chip you have to test by yourself. I can't promise anything.

IMPORTANT!

In the factory settings the correct chip, which is actually built-in, must also be selected!

Hier die gewünschten Bilder von der UI.

Persönlich würden mir aber die Buttons von Y-Serie besser gefallen.

Da man hier mehr Buttons unterbringen könnte unter der Uhr und der Radioanzeige.

Schön wäre es auch wenn man die Uhr und Das Radio auch verschieben könnte und das man auf der Hauptseite die Uhr ausblenden könnte bzw. Statt der Uhr mit Datum auch nur das Datum anzeigen könnte.

Here are the desired pictures from the UI.

Personally I would like the buttons of Y-Series better.

Because you could put more buttons under the clock and the radio display.

It would also be nice if you could also move the clock and the radio and that you could hide the clock on the main page or display only the date instead of the clock with date.

Hey guys,

I asked to my vendor from Witson about a new carplay app. I told him that I upgraded my radio to android 9 and this is what he told me

"We do not know why you use the android 9.0 updating file to used for your W2-V5570 which is android 8.0 software!

The android 8.0 units use different core board with android 9.0 units and android software version can not changed into

Android 9.0 just by the updating file,need to change the core board,understand?"

I have a PX5 with 4GB ram

I guess is because we cannot upgrade without the recovery upgrade from Hal9k
[MTCD Software Development] jamal2367:
You can upgrade with every PX5 boards to Android 9.0... ;)

Use the recovery upgrade from hal9k :)
[MTCD Software Development] paniqueado:

I just asked if there were a new carplay app for Android 9 and Allen from Witson (MX) told that.

2. Despite adding my Gmail account to the headunit, the Gmail app is still asking me to add an account and it's not opening my emails.

3. None of my Dab+ app is getting any signal (preinstalled & Dab-Z). Never had this issue with the Dasaita Android 9 Rom.
