Gala (SDVC) app for PX5?

I can`t find a working SDVC app for my PX5 GS unit. It is my second unit because the first has had a fault and was exchanged. On the first unit I used Graser´s Dasaita tool for volume control. On the new unit that isn´t working anymore and also MyMTCService does not recognise the unit as MTCD and so the sound control is not working.
The only thing that is different to the old unit are the connectors. The GPS connector uses now a Fakra plug, but I don´t think that this is a problem since all other GPS apps are working normally.
Neither Malaysk, the original GS ROM nor a HA ROM is working. I've tried also different MCU's.

Here you can see the problem with Grasers Dasaita tool. I am not driving and not changing the volume level: https://youtu.be/aT0asijim5g @Graser maybe you can help me?

[Xtrons PX5] USB Permission Bug / 8.1 Upgrade / Dashcam wrong speed

Hi there,
I buyed a xtrons px5 head unit for Opel, I installed malaysk firmware 2.0 for further customizations. Unit is running almost fine. Had some overheating issues after long driving with navigation. Dont want to open and add heatsink because losing warranty.
One big annoying problem is USB Permissions Message when using USB CAN Adapter with Torque. Every boot or wake-up from standby unit asking me again for USB persmission for canbus adapter, even if I tap use by default.
Does anyone know how to fix that?
Xtrons now selling units with Android 8.1, what the ****? New hardware? No update for existing px5 units?
My dashcam from xtrons (UCam china chipset) displays wrong speed and perhaps wrong position. My friend with stock firmware has same problem, any fix for that?

CAN adapter - Help needed (Mercedes)

Hi All,
I need to find some info for the Can adapter so i can fix my issue and help other people with similar problems too .Owner of an MTCD PX5 unit, specific for Mercedes ML (W164) that came with the Can adapter.
From day one the steer wheel buttons worked (vol up/down, phone) and reverse camera out of the box BUT i had no vehicle info at all (door opened, fuel level, temperature, parking sensors etc) as many of the users especially on VW units have. The car is a 2010 model therefore the canbus info should be plenty. Tried all the combinations of CanBus under the extra settings with no luck.
One think i noticed is that i had NO Vehicle.apk or microntek apk and MTCCanbus.apk installed on the unit. I tried to install but installation was failing for both. Even copying to system/app/** didn't worked.
Any idea ?
BTW Anyone knows what is the Knob Mode under extra settings ? Mine is set to : 2 10k/20K ADC Ports
Details:
Unit: MTCD PX5
MCU: MTCE_GS_V3.00_3
ROM: Halk9 Mod 3.1 (Android 8)
Can Adapter : GS 10280514 / HW:V2 SW:V3
Can adapter Setting: 23 Benz_B200(simple)

Good to know that this is a generic issue and not specific to my unit and car. It seems a lot of people with Mercedes cars have similar problems. I wonder if this is related with the cheap implementation of the Chinese Can adapters or related with the car.
Will keep searching

Another thread is open with more technical details for similar issue, more HW oriented though here > https://forum.xda-developers.com/android-auto/mtcd-discussion-questions-development

I have the same car w164 and px5 android 8
The same problem.
No I have more problems the canbas stop working no reverse camera no Wheel key vol working and no led light on unit key, I think my canbus dead ?

MTCD/E USB Electronic noise

Hello ...
I have a problem with my eonon (klyde) px3 unit. Ever since I bought it, I have had a problem with usb ports.
When I use the USB dashcam and activate it, or when I use the USB flash disks from the speakers to listen to an electronic hiss, like electronic processing noise.. :crying:
If I turn the volume down to 0 the noise ends.
I tried to solve it like this:
- I replaced with new mtcd / mtce,
- I updated to the latest mcu version
- I flash mcu modified by wadzio( the audio sound is better, but the problem remains.)
- Eonon obviously tells me that it is normal to lower AMP to - 20 but the problem remains the same.
- I connected the chassis of the unit to the ground of the machine.
- I connected a 12v filter that is used in the car units of a good audio brand, to eliminate the hiss of the engine and alternator
Neither of these things solved the problems
Do you know if it is possible to install resistors, capacitors, or solve the problem with me or try to find it? Thanks

You are correct that the problem is a hardware issue and not software.
I dont own this variant, but willing to help - if I can get a unit sent to me, I could attempt to find root cause and develop a fix that could then be shared with the community.

Question PX5 Android 9 replacement no sound

Hello. I fixed the damaged radio by replacing the PX5 module. The radio has started working, however the sound is only from the radio and bluetooth. No sound from USB, internet, navigation - displaying correct. I don't have an amplifier in my car. The radio comes with a CANBUS but I have a version of the car without CANBUS. Could this cause a problem with the sound? Please help.

You are in the wrong Forum. This is for FYT Head Units and you have an MTCD Head Unit. There is a forum for that where you will find the right people.
But anyway, did your unit used to have a PX5 and you replaced it by another PX5? Audio selection and processing happens a the Motherboard (the MTCD). There, the chip in charge of Sound source selection and processing selects from Bluetooth Chip, Radio Chip, and the PX5 (that generates any App-sourced sound like Navigation and MP3 playing). For some reason either the motherboard does not like your PX5 (faulty?) or there is some misconfiguration at the Android Level and PX5 is not reproducing sounds.
Have you changed anything on the Factory Settings?
But definitely your problem is not at the Canbus, but either at Android Config, PX5, or how the MTCD is communicating with the PX5

Thank you very much for the information, I'm new here so I'm still lost. I will move the topic to the appropriate forum. Thank you.

Hi, post system info, mcu version.

It's not an MTCD unit, search forums for CSN2
