Help Needed - Srnubi T10 (TS10) Problems - Android Head-Units

Hi Guys,
A while back, I purchased the T10 unit from Srnubi. It worked perfectly for day 1. All speakers working, subwoofer was loud, everything was great. I came back to the car the next day and there was 0 subwoofer! Nothing was changed, everything normal so I started trouble shooting and I testing turning the bass up on the DSP to max, only then I could very faintly hear the Sub working. I figured I would try to reset the unit in hopes that it would work but now I have a factory android head unit with no running software (except the android auto and carplay software) and still next to no subwoofer output. This lead me to believe that the subwoofer out RCA is not working. I tested all RCA's and they're all very faint (I'm running the speakers from an amp which is connected to the head units speaker wire as the chanels). Has anyone had this issue before and is there a way I can fix the RCA Output without opening up the headunit and looking for faults on the board? And how do I install the firmware that Srnubi has sent through? They've completely stopped replying to me and didn't provide any instruction, worst part is they waited until my 15 days was over to stop replying and now I can't raise a dispute on AliExpress.
Any help would be much appreciated!
Cheers!

DSP output to subwoofer has probably burned (regulator voltage chip inside on board), must be replaced.

Noise Issues - Pumpkin HU

Hello,
I got a very annoying problem with my pumpkin head unit. Theres a noise, like when you place a smartphone close to speaker, which I hear all the time coming out of my car speakers.
Sometimes it's quiet and sometimes I hear that noise.
Is there any way to fix that?
My HeadUnit is (Description from Pumpkin Website):
Pumpkin 7 Inch Quad Core Android 4.4 Car Stereo DVD Player for Opel Vauxhall 2 Din support DAB+ AV Output MirrorLink 3G WiFi OBD2 DVR Steering Wheel Control
I run Malaysk Rom, but had this issues even with the standard ROM.
Would be happy if anybody could help me.
Regards
Ben

No ideas?
Any ideas
I would be happy if someone could help me with my Problem
It's likely noise from the screen. Try turning the screen off and see if it goes away. It won't be easy to fix. Make sure all your grounds are as good as possible and make sure they are as direct to the battery as you can get. Noise like this is from a bad circuit design. It's the difference between an expensive well-engineered board and some POS from China. Yeah, I got one too, the Lollipop unit (self-rooted w/Viper).
If you only get the noise when the car is running it could be noise from your alternator or plug wires. That's harder to fix. You could use one of the crazy capacitors they make for car audio, but if you aren't running a 1000W, they can be overkill. I would try 1000uF cap across the 12V battery supply to ground, as close to the head unit as you can get it. Make sure the cap is rated at least 15V or so (it will see more than 12 from a car!). It will be electrolytic, so make sure you obey polarity. I'll be doing this myself later today.
May be worth a try running a wire from the negative of the battery post to the radio ground...I would just do it quick and easy in the driveway before trying to route it through the car.
Thank you for your support on that...
Unfortunately that sounds not that easy. I thought this might be a common problem with those head units :-/
I have a sound coming thru the speakers as well kinda sounds like a hard drive reading data when its booting up but goes away once its booted & running.
Might try running a better ground see if that helps.

Dasaita 10.2" Android 6.0 head unit - Audio Issue

Hello, I recently installed the above Android unit into my 2014 Mitsubishi EVO with Rockford system. It came with the can bus decoder MT-SS-03 for 2014 Outlander. I set everything up in the factory settings menu but I'm having a major audio problem that sadly is ruining an otherwise awesome experience.
If I listen to any music at high volume all system audio cuts out completely for 5-10 seconds at a time. I've found this problem is directly related to the volume. The louder it is, the quicker the audio will cut out. I've double and triple checked all wiring and pins, updated to the latest MCU 2.59, Android system (8-3-2017), etc.
I'm out of ideas on what to try next but hoping someone here can shine some light on the situation. Thanks in advance and looking forward to putting an end to this issue!
do you have proper canbus?
Yes I do, according to them. I did get a red one though which was labeled for 2014 Outlander which I understand to be the newer can box for 2014-2015 EVO but the pictures I've seen show a black box and mine was red but labeled as the newer one. I thought the older 2008-2013 units were red. Not sure if that makes a difference or not but I do have sound from all speakers so it works it just cuts out at high volume. However, the amplifier settings on the Android unit do respond a bit strange. The sub slider seems to change all speaker output and not the sub directly and has a pretty minimal effect. The fader seems right at least as far as the channels go.
In the meantime I did contact the seller on Amazon about the issue. They told me the issue is caused by the high power protection of the factory amplifier. To fix the issue they want me to re-install the factory radio, turn the volume sliders down to the "middle part" and then install the Android unit again. This seems a bit strange to me but it could be the factory radio interfaces with the amp in a different way and is able to control the gain of the sub and the Android unit cannot. With the newer Android unit I noticed the max volume is much louder so maybe I'm hitting some sort of over current protection causing the amp to momentarily shut down. Has anyone ever heard of this?
What I'm not sure about is when this procedure would be needed. Is it because I had the amp slider on factory unit is set too high before I removed it or is it because I disconnected the battery and the amp defaults to a higher setting that only the factory unit can adjust? It would be a real shame if every time power is cut from the amp I need to repeat the process. I fear that may be the case because I'm not sure the amp has an internal EPROM or non-volatile memory that's saving the settings and I did in fact disconnect the battery.
Either way I'll be happy to finally get to the bottom of the issue and I'm sure I'll find out whether or not I'll need to swap the radios again. Until then I'll keep the factory unit closeby. Luckily it's very easy to swap out so fingers crossed this fixes the problem. It's going to be a few days till I pull the radio out since I'm also waiting for a replacement USB harness since one of mine is inop due to a damaged wire.
Please let me know if anyone has any input about this. Thanks again.
Ditto - did you try swapping back and lowering the volume, if so, did it resolve the issue?
I have only had mine for 3 days, Dasiata HA2106-S720 with Dasaita CB003 Canbus harness in a 2013 Mitsubishi ASX with Rockford Fosgate. I would agree that the volume seems higher, so there could be some truth in the Sellers theory.
By the way my experience with Subwoofer control also matches yours - adjusting the lowest frequencies on the Graphic Equalizer seems to affect the main speakers more than the subwoofer, and I am not getting the same 'punchy' bass as the OEM Head Unit.

You made also the Car Settings to work well ? Things like keyless operations, windshiel wipers operation, lights time out, auto fold mirror, etc ? Thanks.

New Joying unit replacing old Joying - no audio

I am replacing an old 4.4.2 Joying head unit with their new px5 4GB unit.
The wiring diagrams are identical as are the wiring harnesses so I figured I could just unplug the iso connection from the old and plug the new one in.
I get power but no audio. The external factory amp doesn’t seem to be powering on because with the old I would get a slight sound in the speakers as the head unit came fully on in the main screen.
Any ideas? I was going to start testing the pin outs but I just don’t get what could be different.

FYI, to close this out for others. The issue was the AMP CONT pin wasn't supplying 12 volts with the radio on. Tested with a multimeter. Frustrating, and trying to deal with Joying support to send something like this back to China is a PITA.
So, to deal with it I ended up cutting AMP CONT right before the fuse, and then splicing it into the red/accessory wire. Same effect. Good to go now.

Same problem here. I emailed joying support no help yet. I was looking for a setting in car setup that used to be in the android 6 units to tell it you wanted the external amp trigger enabled - I could not find that setting in the new Joying Android 8 unit.
sounds exactly like my issue I have posted on Joying forums and have a long chat with Candy at Joying. I am at a loss because the radio app when it comes on plays just fine via my external amp and sub. But when I switch to spotify or bluetooth audio. I get nothing. then if I mute and unmute I get audio to my front and rears but nothing to my subwoofer. I was looking for the external amp settings like I had in my 6.1 Android unit. Nothing. Dont want to send it back because it is fast and looks great. If I do send it back, I am just going to go with Seicane.
Hello all this worked for me. Try taking the top cover off the head unit and look on the board for the round sticker on top of the MCU (in my case the sticker said TP6735D v43-6686) and search the sticker info. Download only the MCU update with the same sticker info (in my case I needed TP6735D v43) after update the sound is working again. Not sure why the website MCU update takes out the sound. Good thing is, you can rollback . Hope this helps.
Playing music from USB will wake our factory amp, but radio station music does not. What would cause this? Is there a way to get radio to wake amp? I think(?) Amp Cont wire is unconnected.

Xtrons D719AS No Sound from any source

I’m new to this and really appreciate any help.
Just recently installed the Xtrons D719AS single din head unit with android 7.1.1 in a new project jeep CJ7 I’m working on with my dad.
We installed it without using an external amp. Wired the speakers directly to the ISO. (Probably both a bad idea)
We tested using the 2 front speakers at first, everything worked and sounded great.
Then we hooked up the rear 2 speakers and tested with all 4 speakers.
It was all working and sounded great for about 10 minutes, then after raising the volume up about half way or so the sound shut off. The radio kept working with no sound. All functions on the radio work fine but not a peep of sound from any source.
We removed all power from the head unit (unplugged ISO) for about 30 minutes, removed rear speakers (tested with only 2 front), did a factory reset on the head unit with no change. Still no sound.
Did we blow something in the radio? Maybe an internal amp fuse?
If we hookup an external amp and use the RCA connections would the sound possibly work? (Bypassing the internal amp I guess).
Also this head unit does not have a blue/white wire for amp. Only a blue wire for ANT. Should the external amp go on the ANT wire or just hook it up to a Accessory/ignition line?
Also can anyone tell me what the pink wire (reverse) is for on the ISO?
Is that for the radio to know when reverse is on for the reverse camera?
I can return (to China) for repair, but would rather try and fix myself if possible.

Subwoofer cuts off, rear speakers not working

Hello,
I have Android head unit for Peugeot 407, it's PX5 and running on Android 9.0. Issue I'm having for some time is that I have seperate amp and sub attached to it. I have taken 12V signal to turn it on from head unit's I think antenna or something that gave out 12V whenever it was turned on. I sometimes play music louder and after some time subwoofer just cuts off and it remains playing on normal car speakers. I checked already if maybe amp overheats but it doesn't as when I restart the unit (turn car off then on) the signal is back on and it can play again for some time before it cutsoff again. Also other interesting thing is that my rear speakers are not working at all on head unit... the weren't working for quite a long while, not sure if they have correct wiring on that adapter that comes with it to plug it to car. I was thinking of bridging the front and rear speakers together since I don't want them not playing as i've bought them new after my factory ones rotted out. They were working when I had my factory radio in few years back.
