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.

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 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.

Question Doubts about what can be done with a 7862

Hello. I am looking for a radio to install in my skoda Rapid and I have doubts regarding these FYT uis7862.
1- Would the parking sensors work acoustically and visually?
2- Could I see the information of open doors, temperature, etc on the screen?
3- Can it be integrated with the car's on-board computer to see the phone or navigation?
4- What can be done with these radios that cannot be done with a Px6 or vice versa?

Do you mean FYT based UIS7862

Yes

1- Visually (someone correct me if I'm wrong)
2- Depends on your car and canbus
3- Depends on your car and canbus
4- Esasy rootable and many mods available !

@albertron The canbus is one of the biggest unknowns. Unless there is someone with the same car model and audio, amplifier and climate control as you, there is no way to know unless you try it yourself. You can ask the reseller, but if they say everything works and then it doesn't, what will you do?
Each manufacturer/reseller of these Android head units has code that works with the canbus modules. They don't share code. Some manufacturers are better than others with the canbus coding. Your experiences with other head units, such as a PX6, are not relevant as the code on the PX6 may or may not be used in these newer models.
As cars electronics change and become more complex or various items are integrated such as climate control through the head unit screen, canbus coding for the manufacturers of these head units becomes more difficult. My car is a 2012 Kia Sorento with an amplifier. The audio from the head unit to the amplifier is the only thing that uses the canbus that is used by my head unit. The canbus module that the reseller provided did not work and I had to purchase an aftermarket interface module. I was lucky that I found it. If I didn't find the interface module, I would have a paperweight that I would try to sell.
So, if those items you mention are important or required for you, I would make sure those functions work for your specific setup before purchasing a head unit...any head unit.
The above is what I've come to believe and based on my experience with my head unit and what I've read on various forums.

@mariodantas @mastrv
Thanks for answering. So it's best to ask the seller. Really the only thing that matters to me is that the parking sensor and the buttons on the steering wheel work, the rest of the things are secondary. I have also seen that most radios do not include the canbus adapter and you have to buy it separately, spending another €30. I'll have to look first for an adapter compatible with my skoda Rapid. Although I still have doubts about whether to take a px6 or a FYT with uis7862. I also have the option of an rcd330, but it has bugs that are too serious for me.
What would you do? My use will be 90% listening to music with tidal, and fm radio. The remaining 10% I will use a GPS navigator to travel.

Your parking sensors will definitely work. If you get the correct canbus decoder you will also have visual parking sensors display on your headunit.
Chances are it will work as VAG group canbus codes are pretty well known. I helepd a friend install a MEKEDE unit in a Golf 5 and, even if this particular model was not a choice in setup, canbus integration worked out of the box.
PX6 units are obsolete, go for a FYT unit.

OK, thanks. I think I'll buy a medeke or navifly then. First I will ask the seller if it is compatible with my car's canbus. Another question I had that I forgot to ask: 1 year ago I had an Android radio in another vehicle, and the tidal app interface was unusable when in landscape mode. By any chance someone has it installed and can tell me if they have fixed it? The problem was that you can't access the search, or playlist, or anything. Only the music player comes out with the last song you listened to. Tidal is my main music medium, and if it still doesn't work I could consider other radios with original Android auto.

I have a Joying uis7862 based unit. It does or can do all the things you asked. Canbus adapter was included with the wiring harness. Specifically I have the JY-VQ130N4GN in a 2010 VW Passat.
I see that they offer a number of units for the Skoda Octavia. I don't know how similar the dash of the Octavia is to the Rapid.

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.
