PX5 Android head unit no sound - MTCD Android Head Units Q&A

I just bought a Belsee PX5 Octo Core Android Head Unit for my 2016 Hyundai Veloster. It has a custom harness made for the car. It works great, except there is no sound. The backup camera works, the steering wheel controls work. Everything works....except sound. I am trying to work with Belsee via Email, but we all know how that goes. I am wondering if any of you fine people might have any suggestions that I can try.
I have gone into Factory Settings menu and changed the CANBUS to Hyundai &KIA, still no sound. The Veloster requires a signal over the CANBUS to turn the factory Amp on and produce sound.
Thanx in advance.

what did the reseller suggest when you contacted them for support? Was that to change CanBus settings?

Hi, i have the same problem after upgrading from px3... Did you resolve the problem?

I now have sound..had to swap to a harness with a CANBUS controller on it. But, the EQ does not work, the rear speakers are super low, and there is that electrical whine from the engine. But at least there is sound.

Hi I am new here but I also had the same issue with my Nissan qashqai and the Bose system. I have found that on my vehicle in the Belsee power harness that pin 1 was not present which is the 12v positive that feeds the Bose sound system. I would suggest you get a wiring diagram for the cars head unit and check to see if this is the problem.

MTCD SoFia "LM" Head Unit Pre-Amp Output Levels?

New to these Android units.
Does anybody here know of a way to increase the output levels from the RCA Pre-Amp Outs?
I am wondering if settings for this are in the MCU software, or in the Android side of the software. My Radio sounds great with this unit, but the Music Player app seems to have around 30, or so percent less audio volume. I have searched, but so far found very little about this issue. Any help will be much appreciated.
I ran into the same problem, so I've used a NVX LOC with independent gain controls for all 4 channels.
Thanks for your reply
Thanks, but I want to keep the factory Bose amp, because I have read in several places that the speakers in the car have a non-standard impedance that the amp is matched to. Besides that I want to keep all the wiring in the car stock so I can put everything back to stock later if wanted. There must be some way to increase the output in the units software somewhere, so I am hoping that a software guru will chime in here at some point and tell me something like: "oh, yeah, just change the values in the such and such file located in the sub folder of the System folder. I'm patient, so time will tell.
Doesn't these factory sound systems use proprietary connectors with high level inputs? I've never seen a factory amp with RCA inputs.
Proprietary Factory Audio Systems
Yes, in my case with the Infiniti Q45 it is is a proprietary system, but I used a Metra aftermarket connection adapter (Metra 70-7551) to tap the original wiring plugs that normally go into the back of the factory Bose head unit. The Metra adapter allowed me to make the connections without having to cut up the factory plugs. It included the 4 RCA plugs to tie into the original feed wiring going back to the amp in the trunk. Helped me keep everything nice and neat, and eliminated the need to run speaker wires, or make splices into the amp inputs. I also used a Metra 40-NI11 antenna adapter to convert the Nissan proprietary antenna lead to a standard antenna fitting to go into the new Android radio. I don't sell Metra stuff, but only mention it here because it helped me do a nice clean install of the new radio, and it gives me the option of going back to stock very easily.

isn't that the "input gain" settings, usually reachable via factory settings?

Steering wheel controls not working

The steering wheel controls are not working. I loaded the steering wheel keys app. The app does not show any key as being pressed/detected.
There are 4 plugs on the Dasaita harness. There are two connectors in car plus antenna.

The Nissan medium plug and the low plug are the same. Medium plug has more wires in it.
I connected only these two plugs from Dasiata harness to the nissan car harness

What is your HU model number?
Check under Factory settings/canbus for a suitable option for your car; based on some Dasaita units wiring information your car need a decoder named CB008 if you previously had the default 7" screen unit
Usually you need a canbus decoder box to retain SWC controls or maybe you need connect wires named KEY1, KEY2, KEY GND to steering wheel for use controls.

Try other nissan Xtrail/QASHQAI/Rogue canbus "voices" in factory setting and check if they working after reboot.
For the "Locked..." i think you need use the radio unlocking code provided to you when buyed the car

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)
Hi, i have the same car the same headunit and the same problem.
All is fine but i want to have more can-informations/functions.

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 ?

Max6 PX6 full system audio stopped working

I had been using my unit for more than 6 months and everything was great, I got home from school during spring break and installed my rear view camera. Camera works fine, however, now there is no sound from anything. I uninstalled this unit and re-installed the original from the car and everything was fine all speaker worked as did volume and changing stations. Re-installed the Dasaita unit again no sound. I tested all the plug and play wires from plug to plug and there were no shorts and all wires passed a continuity test with my voltmeter. I tried undoing all the rear camera work that I did, this didn't change anything. I have factory reset the unit more time than I can count. I also installed the newest software and firmware updates (MTCE version: V3.45 and MAX6 Version : PX6 HA2_rk3399_9.0_ota(20200320)).
There is no sound from the radio, from Apple Car Play, not even sound from the side unit volume buttons.
My car is a 2008 Honda civic LX, and any suggestions would be greatly appreciated! I am currently out of ideas.
Thank you,
Austin
Same exact thing happened to me.
Are you using the RCA outputs into an amp, or the speaker-level outputs via the 20pin connector on the back of the head unit? Have your CanBus settings in the Factory Settings changed at all?
20pin connector. I had to install a new motherboard that I got from Daisata due to my wifi not working on the previous board they sent me. Now I have no wifi and no audio with this board. I tried all the CanBus settings that match my Jeep, but no audio. The steering wheel controls do work, so it seems like I have the right CanBus selected.
When all audio goes, including button beeps all you can say is it's dead Jim. How dead might make the difference between sending it back or fixing it. Of course make sure it's not on mute. You could always start by contacting your seller for warranty. Next connect an amplified speaker to the RCA line out, if you get sound that means the amplifier IC is not working and it's a fairly easy fix. Unless you had other issues with audio before it's likely bad solder joints on the amplifier pins. You could re-heat the pins with an iron but it would be better to remove the old solder and replace it with good 60/40 lead solder.

Took me a while to post the previous one and I just saw your new post. Is there another board that connects to the motherboard? Units with 2 boards have a MCU and a SoM. The USB comes from the SoM and goes to a hub on the MCU. The WiFi board is connected through USB, check if your USB ports work. The pins of the female SoM connector can get damaged, some people have fixed it with metal foil as mentioned in the warning on this thread.

In the CanBus settings in the Factory Settings, there is a selection "With Amplifier/Without Amplifier" and as far as I can see, this selects which outputs you are using (ie speaker-level outputs on the 20 pin connector, or line-level outputs via the RCA connectors). It also does some other things likes make parts of the DSP unavailable, but try flipping this selection and see if you get sound.
I think that refers to whether you have the built in amplifier that comes with some Jeep models or not. Unfortunately, I tried both options and neither work.
Were you able to get this resolved?
I have the same problem with my Honda Civic 2012 LX.
I have the same problem.
I bougth a new head unit. Everything works exept the sound.
But the System Sounds and the radio also work. I tried different can settings also without can.

Question Xtrons Head unit for 2010 Lexus IS250, cant get some Steering Wheel Controls to work!

Hi everyone
I have a facelift 2010 Lexus IS250 F Sport, I've had some large success installing this XTRONS head unit for it and I am largely satisfied with it. I am however having an issue with getting Steering Wheel Controls to work with the head unit.
Lexus | Various | Android 10 | Octa Core | 4GB RAM & 64GB ROM | Integrated 4G Solution | PMA10ISLS
XTRONS PMA10ISLS is a 10.1" large screen car stereo with customized face panel and optimized CANbus Decoding for Lexus. It supports CarAutoPlay, built-in DSP, PIP mode enabled ,Dual Theme, Instant Rear Vision and so on.

Lexus| Various | ISO Wiring Harness | MOST
This ISO Wiring Harness is compatible with XTRONS custom fit units PSP10ISL,PMA10ISL etc. If your car is Lexus IS250/IS300/IS350 Convertible (2-door)with original navigation or fibre amplfier system,you need this cable to aid for the installation.
xtrons.co.uk
This is the unit I purchased, alongside a special wiring harness so that I could use it with my vehicle as its a facelift Navi.
With the default CANbus setting on my head unit, only Volume control seems to work and the phone call buttons and voice command buttons are mapped to functions like Radio and Hey Google but I cannot programme these on the app. With an alternative CANbus setting I get skip track functionality but I get different AC Controls and lose access to my factory amp settings.
The original wiring harness I got for the headhunt has not been used at all as I was instructed to usr the special harness, and that original harness had a CANBUS decoder. XTRONS claim that I am unable to programme the SWC due to the CANBUS needing to decode it, although I have played around with the settings and selected various different CANBUS settings.
Would anyone be able to advise me on how I can get the SWC working, would it involve plugging the CANbus decoder into the head unit? There is a 12 pin connection spare at the back but I am unsure if that would make the difference or not.
