PX5 Android head unit no sound

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.

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)

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 ?

built-in canbus decoder

Hello, I bought car (Peugeot 307, 2005 - restyle) with already installed px5 headunit. The seller gave me a link where he bought it: https://www.erisin.com/erisin-es788...seat-peugeot-307-dab-gps-dvd-p0178-p0178.html
"(...) 7" All-in-One Design for old VW Cars with built-in CanBus Decoder..."
Car has no working steering wheel control (no external canbus decoder), but the auction on aliexpress says it has Build-in canbus decoder. I tried to activate it in Car Settings. I plug can-H and can-L wires into big black plug (numbered as 17 in the photo), taking schematic from this auction (where my friend with skoda superb bought the very same looking headunit);
https://pl.aliexpress.com/item/32809484570.html?spm=a2g0s.9042311.0.0.27425c0fPeznkJ
My question: is there a chance to run it without external canbus decoder? How to do so?

Is it an MTCD

it is MTCE unit

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.

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.

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.

Joying 7” alfa romeo brera

Hello all,
I have installed a Joying 7” unit on my brera with bose system, without blue and me.
I can’t make the steering wheel comands to work.
I previous i had a Josmile PX5 unit with this steering wheel adaptor (alfa-bg-01) and it worked, steering comands, temp, volts, door open, trunk open.
Now i have connected the can adaptor RX to key 1 and TX to key 2.
On the car socket i have 5 pins:
- 1 can b high - to can adaptor
- 2 booster in - no connection
- 3 can a low - to can adaptor
- 4 +12V - to player +12V
- 8 GND - to player GND
From the can adaptor i have a blue wire SWC witch i don’t have space to connect to headunit socket
I attach:
- picture of the adaptor
- wire diagram of joying
- wire diagram of the socket adaptor (as the wires entered the old PX5)
In the joying factory/can bus alfa romeo does’t exist, i contacted joying europe and they said to leave to none and also couldn’t figure why comands don’t work.
Can you guys help me please?
