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

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.
Hi,
So I just want a simple answer to what the logic behind the "subwoofer level" setting is on the head unit. I am now onto buying my 3rd head unit as the first one was a JOYING 10.1inch which was actually perfect but I had to sell it on due to buying another car and not wanting such a big screen.. Needed something that would fit the interior properly so I had to sell the head unit (Wish I didnt as this headunit didnt have a single flaw).
Now the issue starts! I then bought a JOYING 8inch VW headunit with android marshmallow on it and I then installed a subwoofer to it. What I dont understand is this new "Feature" where the sub woofer volume/frequency is controlled seperately from the rest of the speakers which are controlled with the volume knob. Which idiot thought of this!? The problem starts when you turn the volume knob down but oh wait, the sub woofer is still booming really loudly. You then have to go into the subwoofer level setting and adjust that to the volume you want.. and then when you want to put the volume louder, you have to readjust the sub woofer level again!!! Why would you bloody want this when you have sub woofer controllers you can install easily which do the same job!? I then thought okay maybe it is a flaw with the head unit so I sold my brother the headunit and of I went to look for another one.. I thought not going to get another joying again so this time just yestarday I saw the EONON GA8153A octa core android 7.1.1 and I thought WOW I have to buy this.. So I emailed the company to ask about this stupid subwoofer level feature and fingers crossed they didnt have this same feature built in to their head units but so do they!? It would be fine if it actually worked properly but everytime you turn your volume down, you have to adjust the subwoofer level as well and turn it down or if you dont, you have a car which is playing no highs or mids but a crazy amount of bass. It is stupid! Long story short.. I did ask them if they could create a custom android 7.1.1 firmware which will control the sub woofer volume together with the the rest of speakers but its not possible for them yet all these single din head units you see, SONY, PIONEER etc etc have this implemented properly.. Someone please enlighten me on this situation? Any software guru's out there who know how to modify the firmware and make this change possible? Rant over.
Thank You.
This issue must have been introduced on Joying's head units with 7.x ??
My single-din 6.0.1 version JY-UMS03N2 with 7" screen controls all 5 outputs correctly. As far as I know, they also do the same head unit with 8" & 10" screens ?
Might be worth a post on the Joying forum. They do seem to respond occasionally.

They are not calling it an issue.. I contacted joying themselves who said it was a feature and the head unit I purchased yestarday from EONON have also said that this is what the customers asked for yet it doesnt make sense why the customers would ask for this.. I understand the fact that yes you can adjust subwoofer for whenever you dont want it playing then okay understood HOWEVER it also has its negatives where when you do have subwoofer on, you cant control the volume at the same time as when controlling the speaker volume too which makes no sense.
The issue/feature is not with all type of head units because I had a 10.1inch which you have just the bigger screen and that was fine and all outputs adjusted at the same time but the one I am looking for which is this http://www.eonon.co.uk/upload/product/Gallery/GA8153A/GA8153A-01.jpg seems to only adjust the outputs seperately which makes no sense. I will write it on the JOYING forum and see if they come up with a solution but I have already emailed them and they said no solution.
Thanks.
It seems these manufacturers have separated the subwoofer gain from the volume control. Nice to know before I buy. Definitely NOT a feature.
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.
Hey guys,
I bought this: https://www.aliexpress.com/item/33028336644.html?spm=a2g0s.imconversation.0.0.1f993e5f5E88oc
And I finally got everything to work smoothly but the SWC is not working at all. I had a 2011 subaru nav without the harmon kardon audio and I searched for like 2 days now and can't find anything that helps.
I went into factory settings and tried to reset everything I wound up messing up all my buttons on the HU and flipping the screen etc.. I fixed it but it was annoying at 10pm lol.
Any tips to fix this? One of the main reasons I got this was for SWC plug and play.

I dont have any experience with Dasaita Head units; I only have experience with ATOTO. That said, I did install an ATOTO Head Unit into 2011 WRX with factory-installed Nav similar to yours. I have the same buttons on my steering wheel as you do. I was able to get the SWC working with ATOTO.
I looked at your video and it seems the Dasaita Head unit is not sensing when you press the SWC buttons on your steering wheel. So this might be a SW issue in the Dasaita, a HW problem with Dasaita, or a wiring problem in the Dasaita harness.
From the link you had posted, there are two harnesses available (DXY022 and DXY029). I assume you have DXY029? It looks like this harness should be totally plug-n-play compatible since it has both the 20-pin and 24-pin connectors for Subaru. Since it's not working, it is possible the harness is not actually compatible with 2011 Subaru, and you may need modify the harness. Out of curiosity, is all the other functionality of the 24-pin connector working (like reverse camera, Bluetooth microphone, AUX audio and video input from the console box) ?
A few ideas to start:
Does Dasaita have any tech support and have you reached out to them? This is a long shot but worth a try to see if they have any suggestions.
Are the wires on your DXY029 harness individually labeled? If so, are the wires labeled with SWC attached to the correct pins on the 24-pin connector?
The pin outs on the Subaru 24-pin harness are documented in this thread.

Hey thanks for the response, this is coming straight from an unmodified headunit. Had the same one since I bought the car and i'm the only owner.
Yes, I got DXY029.
My car does not have AUX but it had video in and out that i made work as AUX. It also had a cigarette lighter in there that works.
All bluetooth works, apple carplay works, audio works, radio now works after I bought an adapter (although the reception is horrible). SWC is the only thing not working and yeah it looks like there is no connection at all. I unplugged and plugged in the harness a few times to make sure I was making connection, still nothing.
I can try and open it again and look at it but the way it was plug and play wouldn't let me plug it in upside down or any other way, so idk why the swc wouldn't connect if everything is lined up.
I've been on tech support with them for like 4 days now and they keep saying they'll have an engineer look at it but are taking a while. That nasioc url says 404 for me.
Thanks for your help so far!
Yes, I agree since the Dasaita was plug-n-play, there's really no way you could have messed up the connections. Since it's not working, i'd say it's definitely a Dasaita problem -- either their SW or their HW or their harness isn't really plug-n-play for Subaru with Nav. I'd push on Dasaita to either fix the problem or provide you the needed technical support. You'll need a description of the Dasaita SWC circuit and especially a wiring diagram of their DXY029 harness. Lacking this information, you'll be stuck reverse-engineering their harness or living with a broken SWC.
The good news is that the Subaru SWC for your STI is quite simple -- there are only 2 wires involved which are found on pins 3 and 15 of the 24-pin connector. There is no reason why we cant get this working if Dasaita helps. The amount of resistance between those wires will vary between 4.7K ohms (no key pressed) to 22 ohms (mute button pressed). Note again that Subaru SWC does not have resistive path to ground.
BTW, this is the NASIOC url i meant to post, which has the pinout for the 24-pin nav connector for Subaru 2008-2011:

Got it! Gonna keep pushing on them to see if they can provide any of the details. Or maybe send me a new harness.
EDIT: they don't seem to be very helpful...
This is what they're sending back to me:
"hi
they said have installed some of the same model , and it works after set the steering wheel key functions on the head-unit , it should fit"
I took out the radio again and tried to replug everything back still no good.

That's disappointing that they are not providing good customer support, other than telling you that it should just work. I would definitely continue to push them to make things right with whatever leverage you have. I see the DYX029 harness is only like $9, so you would think they could at least send you a second harness to see if it helps.
When attempting to program the buttons on your steering wheel, have you tried pressing the button for a few seconds? Just a random idea. I assume the user manual has no secret instructions or useful info? I know most Chinese head units have terrible user manuals. I couldn't not find any public user-manual for that head unit.
I looked at the video and pics you sent as well as online pictures of the DYX029 harness. The wires that carry the Subaru SWC signals are the black and green-white wires which i noted with red arrow on the first attached pic. Sorry for my terrible drawing, but those are the wires you care about. From the DXYX029 Harness picture, I think those wires are in fact connected to the Head unit. So as best as i can guess, the harness looks like it might work, assuming you dont just have a faulty harness.
Assuming you dont get any useful help from Dasaita, and you want to get this working, my suggestion would be that you try tapping into one of those wires. You can use T-Tap to easily tap into the wire), then connect the tapped terminal to chassis ground. It doesn't matter which of the two wires you tap. This is exactly what I had to do get ATOTO working, and the reason is because ATOTO engineers misunderstood how the Subaru SWC circuit works. I'm just guessing that Dasaita made the same mistake as ATOTO, so it's posssible this wont fix your problem, but I can assure you this experiment wont cause any damage to the Dasaita.

Yeah I tried to hold press for a few mins and even factory reset after pluggin back in securely. I'm gonna see if they can send me another harness, might take months tho, maybe I should just try to tap it, worst comes to worse I buy another harness.
I'm just annoyed because others have this working as plug and play with the same car, which kinda leads me to believe I have a faulty harness. :/
Again, thanks so much for all your help. I'll update you with any info I get from them.
Did you ever figure this out?
Bumping this post if any solution was found. I have a Dasaita unit on an 08 STI, and have the exact same issue. Everything works fine on the head unit except the steering wheel controls.
Check and see if your speakers are wired correctly, if you move the balance and fade you will find out. My whole wiring harness was wired wrong and I had to repin Dasaita's harness. Once you figure that out and have the swc wires right you will have to tap and ground swc2 to the chassis. This is the schematic I used for my 2010 STI.
Thanks!
So I took out my harness, and yes, they did in fact mix up the speakers on the harness. The dasaita Rear Left- goes to the Subaru Front Right -, and it goes on from there, so the speakers are all mixed up. How did you happen to repin it? Is there a way to pull out the wires off of the harness easily, or do I need to tap and re-solder them? Edit: Found it, from within the WRX-pinout link below, there is a plastic clip right by the pin in the harness, just take something thin, lift up the plastic clip, then the wire pulls out. This is on the Dasaita harness side of it that hooks into the car connector.
The Dasaita Key 1 does go to Subaru SWC+, and the Subaru SWC- goes to a bundle of grounds on the harness. So it isn't a complete mess like the speakers at least.
So just tap SWC- that goes to the bundle of ground wires and have it go to chassis ground, or do I need to do something with Key 2 coming off the Dasaita harness?
Thanks. Here are all the resources I referenced to help:

And finally the Dasaita manual which has their harness pinout.
I would repin the Dasaita side of the harness incase you want to revert to stock. I just used a screwdriver pick to depress the pins, they pop out fairly easy once you get the hang of it. I can't remember 100% what I had to do with the second swc wire, I will pull my stereo tomorrow if i have time.
Finally figured it out and got it working.
It looks like they also butchered the nav harness pinouts there. It's as if they pinned it looking in a mirror, all the pins were in the wrong place.
I had to re-pin their harness that goes to the nav connector on the subaru, and finally got the damn thing working. I only left the SWC + and -, brake and reverse pins and left out the rest (don't need them). Maybe I will hook up the audio ones later on but I don't need them. Here is the picture of it repinned.
To re-pin it, in the harness on the dasaita harness end that adapts to the subaru nav harness, there is a little rectangle above each pin. Had to stick a small precision flat head in there, wiggle it around, then try to pull out the wire. Also used a pair of needle nose pliers to grab the pin itself and push it through for the ones that gave more trouble.
Thanks for all your help. Really got me to sit down and go through it all wire by wire to realize their mistake with the harness.
Glad you got it figured out. The good news is that once it's wired correctly the head unit is quite good.
Hey glad you guys figured it out. I'm sorry I've been inactive. I kept trying to reach out to them and they kept giving me the run-around.
