Subwoofer Seat Sound not working - MTCD Android Head Units Q&A

Hi all,
I have a Seat Leon 5F with Seat Sound (so including a subwoofer). I've just installed a Witson PX5 W2-V5570 Android 8 unit. It's working fine, except for subwoofer (not working) and probably also center speaker.
On the original system, the signal for the subwoofer is coming from the quadlocker, but this doesnn't seem to be processed in the Android unit..
Anyone familiar with this? Know a solution?
Many thanks!

I'd say cut off the wire and solder it onto the extra cable used for subwoofers. But I'm not sure how the connections on this device are

Hello.
Do you still have your head unit ?
Thanks

Yep, how so?
I intend to sell it though. It works, but i cannot get the sound to work properly. I have sound, but it appears it cannot drive all speakers from seat sound.

Eonon GA8157 - Audi A3 8PA 2006

Hi there guys.
I just bought a piece of Eonon GA8157 from Eonon. After the install, i got a few small issues (or big, depending on my mood ). Although the biggest of them is that my rear amplifier, that amplifies the subwoofer and the rear speakers isn't working, i have no ideea why, because i have alot of cables, and they were just plug and play.
My problem is the internet. I have two modems along with sim cards inserted. One is ZTE MF667 and the other is ZTE K3565-Z. None of them works. I don't know if there is a list of supported modems, but i thought that they were just plug and play.
From what i understand, i can however make these work if i root my device. I'm great at rooting mobile devices, but i don't want to ruin something to this head unit because it seems hard to modify something.
So, that is the question. Can i root this head unit, or install another firmware, or something to make this usb modems work?
If not, can you recomend me another modem? this unit is dead without internet connection, and i don't want to drain my phone battery by hotspotting it.
Operation System Android 7.1
CPU Processor RK3188 1.6GHz Cortex A9 Quad-Core
RAM SAMSUNG DDR3, 2GB
Memory 16 GB
Based on what i read, i guess that my device is PX3.
Thank you, in advance!

I have a 2007 A4 with a MTCD_XRC head unit and I also have the rear amp, but I notice that the rear speakers are much lower then the fronts. I bought a line level converter and was messing with that and a ground loop isolator to get rid of the engine noise. But I have noticed after messing with it, even without ANY rca cables plugged in I still get audio out haha. I have looked at the wiring and I believe what needs to happen to make things totally correct is you need to rewire the back rca cables to go through the converter and completely bypass the rear amp as the head unit has enough juice to power all of the speakers. I also noticed after messing with things that I no longer needed the isolator on any of the speakers and I just moved the center to the rear a few click and it seems to level things out for the time being.
I've messed with a Huewei Cricket USB 4g dealio here and I was able to kind of get it working by using the PPP widget, but I was not getting connected, but the lights were changing so I am pretty sure its working, it just needs some fine tuning (I have project fi as my service provider)
I can try to help ya out if you need a hand, but I if you look further into some of the stuff I have mentioned I think you can figure it out.
Hi, thank you for your comment!
I was thinking at the same ideea yesterday. The amplifier from the unit is very powerfull, much powerfull than the audi one. My front speakers are more powerfull than ever, yet, my back speakers aren't.
My ideea was to rewire the back speakers to the back of the head unit, and connect them in line, but i have no ideea how the subwoofer works. I didn't saw any wires for it. Maybe he's connected in line with the rear speakers?

The built in sub runs off of the rear amp as well. I disconnected and removed that a long time ago and I have a box in my trunk with 2 x 12 inch subs and a separate amp in the back left (It used to be mounted on the back side in the truck of a rear seat). And now with the android unit I ran a dedicated RCA from the back to the trunk for my external amp, I used to run it off of the line outs I tapped into on the rear stock amp.
So if you just wire to the rear speakers directly you should be good.
Thank you!
That was exactly what the chinese guys from eonon said today.
Rewire the cables and i should be good.
I will try this and see if it works along with the sub.
If not, i will rip all the wires, rewire the rear speakers directly to the head unit and buy an aftermarket active subwoofer, and connect it to the sub RCA of the unit.
End of story

Not exactly the same, but some good similar info just to dig through to get ideas, I do not agree with all of it but just good to mull over. I have so many pages saved of people talking about similar stuff when I was doing research on mine haha.

Nissan QASHQAI/Rogue Dasaita PX5 Installation

Hi there,
I'm trying to install one of the Dasaita PX5 headunits in my new QASHQAI and I've hit a snag. Two of the connectors on the wiring harness included with the unit are identical, but have very different wires coming out of them. I assume they are dependant in your cars factory setup, but since my unit didn't come with any sort of instructions I'm at a loss as to what they are.
My car has the small colour LCD from factory, with a factory rear camera (not the 360 camera) and front/rear parking sensors. Standard manual AC controls (not dual climate).
Any guidance would be appreciated!
I would assume that the "Low Plug" is for cars with low a equipment variant (as you can tell from the cables going into the connector already) and the other one is for cars with a more stuff.
So as of your cars description I would say go with the medium one and test it out.
Yep, I had a better look at the existing wiring loom today and the wires matched pretty well.
Decided to give it a try and it works brilliantly!
Factory rear camera and steering wheel controls all work, and I swear the audio quality using on board apps is better than the factory unit.
Hello, is it an android 8.0 unit ? If yes, does bluetooth works ?
This unit runs Android 6.0. There are 8.0 upgrade guides floating around but I honestly haven’t had the time or inclination to try it, the unit is working really well as is.
Bluetooth phone calls work great.
Bluetooth audio streaming works but I’ve used it maybe once briefly (I do all music and streaming directly on the headunit) so I cant really comment on how well audio works.
Ok thanks, I'm considering byuing a dasaita but I heard bluetooth doesn't work with android 8.0 units !

hi mitchello,
I have the same car radio model, I have a question about the cable connection for the rear camera, I have a yellow cable from the power cable called cvbs, and two yellow cables on the camera aux cable, one says Aux Video In and the other Cam VIN, to which should I connect the Cvbs cable?
?

Have you connected the reverse trigger wire? I *think* its pink in color.. or blue. You'll probably have to splice it. This trigger is connected to your reverse gear, so that when you are in reverse, the screen will switch to camera.

Hey mate, I'd have to pull out my unit to check, but I'd expect you connect it to the CAM IN connector. The White/Red RCAs should be for the AUX input in the armrest, and the yellow RCA for the camera.
I assume you have a factory camera yes? With it all connected my factory camera automatically flicks on when in reverse (even if the unit is still booting).

I'm really drawn to this head unit for my 2017 Rogue SL AWD. My current non-Android Auto/Car play unit is basically just a bluetooth steamer. The built-in maps are so slow, outdated, cumbersome and without helpful traffic info that I simply use Google maps. This new unit looks sharp and allows full functionality without paying Nissan that crazy monthly fee.
I'm in 100% if I can more or less just do a swap out.

Amazon has one listed with the PX6 CPU, so maybe slightly updated... "Dasaita 10.2" Android 9.0 Bluetooth Car Stereo Head Unit with 4G RAM / 64G ROM for Nissan X-Trail Qashqai Rogue 2014 2015 2016 2017 Car Radio Touch Screen GPS Navigation Support USB Bose AMP" at 499.

I bought mine from Ali Express ( Dasaita 10.2 - PX6 Android 9 ) and shipped to Australia in 5 days, I couldn't be more happier with the head unit.
All the Qashqai functions operate including the 360 all round camera, TPMS, Android auto and Carplay.
Hello All
I have dasaita px6 installed on my Qashqai as well
I want to know external MIC location best place as the built-in MIC was good initially then it became poor
Installed external MIC under the steering wheel but still voice is far
Hi all, i have Nissan Qashqai 2018 and i just few days ago i got my Dasaita PX5. Everything looks fine and work very well, but I am little bit concerned about noise which is coming out from device. Every time when I accelerate I am getting some kind of whistling noise coming out from device. Noise sometimes disappears but than come back again and started to be very noise. I tested and its coming from screen device, only disappears when I unplug the big black plug (which I think it is a main electrical socket or power supply because without that is not working). Do you guys have any similar issues before? Do you have any suggestions how to fix same one?
Second question is regarding to the SWC option. I connected everything how they did suggest but still is not working. I did choose proper settings on display and still nothing changed. I tried to contact support but until today no answer.
All help is more than welcome

Had the HU for over a year now and it's faultless,everything just works i.e Factory Park Assist, 360 all round camera, GPS,DAB+.
Also I have the Carlinkit Carplay USB dongle which for me works every time with no issues where others have issues with inbuilt Carplay HU using ZLink.

No audio out the amplifier

Hello,
I purchased a used Seicane unit that has no volume out of speaker wires. I bench tested this and also tested in the vehicle trying many different MCU's and ROM's and no luck. Sound is playing just find out of the RCA jacks to an amplifier. I have since upgraded the unit from a PX3 to a PX5 with Android 9 from Witson. Unfortunately, I updated the MCU to 3.14 before I read that you cannot go backwards to the 2.# series. I was wondering if there maybe a setting I can change that would affect this? TIA
Send it back! What did the reseller suggest when contacted for support?
Have the same problem, but I have builded in amp for rear speakers in my car. So at least have some sound, will buy external amp anyway. Px6 android9

PX5 Audio problems: Schreeching sound!

Hi,
I have the Seicane PX5 MTCE HF and it was working fine until 2 months ago, a screeching sound happen and then no more sound!
I have contacted the sales person and I was trying to get it fix, with the support.
They never heard that sound before.
in any case, they can't help.
I would like to know if anyone can identify the sound and if it is possible to fix.
I'm ready to use a USB DAC if nothing else work.
The sound happear every time I start the car, about 1 to 2 mins after it started, then nothing... until the car cool again.
Before the screaching sound happen, the unit work normaly, the sound is normal.
Even if there is no music, the sound happen.
Any input is the same results.
The rest of the unit work the same, just no more sounds.
*** Results ***
I want to thank you all for your tips and things to look for.
I did find that the amplifier IC is way too hot and did crack the PCB on the edje and few coposants have crack too.
I tried to replace them, but still the amplifier is still too hot after I fill out the gaps beteen the IC and the cassing.
In any case I decided to replace the unit.
I bought a YT9213A_00009_v001_20200806
8227L v 3.4
MCU 3.1 (?)
... and I regret it, no output for the back speakers, no base sound at all!
I bought an external amplifier 4x50w and 600w subwoofer and the RCA plugs have no output on the back two speakers and no subwoofer output!
So, it is slower than the PX5, the radio is only FM and loose the signals all the time, sometime it switch the station by itself!
I'm not happy with the unit, difficult to do setup as of now, the buttons on the side are no longer working.
Like I said, not happy.
If you know a way to reset ALL options to get back the buttons, that would be a step in the correct direction.
Thank you again for all of your tips to fix the PX5.
Richard.
When I took my HU apart I found there was a load of heatsink compound between the amp IC and the case indicating there's a large gap between the 2. I used thermal epoxy to shim the case and close the gap but there's a good chance simply re-mounting the board would have been enough.
All you need to do is undo all the board mounting screws except the ones for the amp. Tighten the amp screws but don't go crazy they're fairly small screws and won't take too much torque then put the board screws back in with a small screwdriver so not to over torque them.

Hi nic2k,
Thank you for your suggestion, I'll have to wait until the weather is a bit warmer.
Thank you for looking into this bizarre sound.
Have a great one!

You could try to upgrade the MCU to this one if your version is lower and your head unit doesn't have a dedicated DSP chip:
latest MCU HF available on the net: V3.30 sound patched for better audio
dmcu(MTCE-HF-3.30sp+by+cs-x).7z
https://mega.nz/#F!T1FgjA7A!wc9p40bocqCiBX8XPR50ig?jhUEmAYD
Hi themissionimpossible,
Thank you for the MTCE file, I already update to v3.30.​You mentioned: “... your head unit doesn't have a dedicated DSP chip”, how can I know?
There another effect from the new version of the MTCE: the Wifi selection under [Setup], [Car], [Factory Setup]: the Wifi module name is not there anymore, nor the Bluetooth!
So even if I tried each one, reboot, test… still no Wifi or Bluetooth for now, but that’s another story.​
I’ll try nic2k's suggestion when the weather cooperates.
Thank you again for your suggestion, much appreciated.
Richard.

Besides looking inside the HU for the DSP board, you might find from the specs if your unit has this option included (indeed not very common...)

Unfortunately you don't look to have a MTCB or MTCD/E head unit, so you'd better ask in the general section:

Px6 Dasaita rca level outputs not working

After a few months of running a stock stereo system, I decided to spend 3.5k on a sound system and can not get any signal to come out of the rca outputs to the amp. Ive been scouring the net all week and all ive found is solutions to noise. I get 0 output from my rca's. Neither "Sub1 or Sub2" outputs work, and win i try and hook subwoofer up thru rear rca's, they dont work either. Anyone know the solution?

Mtce I believe
The RCA's just work. There should be no adjustment needed to make them work. Are you SURE there is no sound coming from the rca's? Maybe you just don't have the amp turn-on wire connected (blue wire). It's a pretty common mistake.
If you are SURE there is no rca audio then the unit is defective.
There isn´t any configuration about RCA on the unit. I have the same one. Only you have the option to turn on or off the amp remote cable. But just that.
In the Amplifier app where you can sett your EQ etc you also have a tab where you can change levels for loudness etc. In there you also have the opportunity to turn the sub ON/OFF and set the gain level of the sub.
