Eonon Android 4.4.4 head unit - BUZZING MICROPHONE!

Hi just received an "EONON" android head unit that I bought on ebay.
It is the KLD RK3188 Android 4.4.4 version with no DVD player.
The unit is great, except for one major issue. The microphone is useless, both the internal and external mic produce very loud continuous buzzing both in phone calls and in Android apps.
I saw some others had some issues similar to this on other units, but I have not seen anyone mention this on this specific one.
Does anyone know of a fix for this?
I have tried a usb mic, but I can't get the device to use it as default.
Any advice would be appreciated!!

Its not an Eonon, they are just re-sellers, its a Klyde unit, they are all the same basic unit apart from screen size and front design and whether they are dual or quad core, read the main HuiFei thread, specifically the first page for a solution to the problem (You DONT want to use a USB mic as it probably contains a sound card so ALL Android sound will be diverted to it).

Solved

Thanks for the tip.
I actually was able to fix it by following that solution. I removed capacitor C32 and connected an external mic directly to the bluetooth module.
Phone calls are great now, Android is still using the internal mic with the crappy audio, but it seems like it would be difficult to fix and it works at least well enough for some basic voice commands which is all I need.

Hi
Burnaby BC, is your unit KLD ?
if so can you explain what you did ?
I understand that you have to remove capacitor C32 but what I don't understand is how did you do the second part(connect external mic directly to the BT module.)
thanks

Yes my unit is a Klyde (KLD) unit.
Look at C32, it should be next to the bluetooth module (unfortunately I don't have a picture).
Follow the trace that connects C32 to the input on the bluetooth module.
Once you remove C32, connect the microphone positive lead (+) to that input.
Then connect the microphone ground/negative (-) lead to ground or a case screw.
This will fix the bluetooth phone call audio.

I recently installed eonon headunit. I was able to mirror my s7 edge onto the head unit. I updated my s7 to android 7 and now i cant mirror the two unit anymore.
I can use bluetooth to stream audio on phone to headunit

New Joying 5.1.1 Bluetooth calling audio terrible.

I just purchased a new 7" Joying 5.1.1 mtcd unit. The audio during a Bluetooth call is awful. It comes through so broken up I can barely understand the person talking to me. It's not my phone either because I tried another Bluetooth headset and it worked fine. Any ideas on how to fix this?

Per mtcb thread, the same mic issues exists as almostevery cheap chinese head unit, including the wince units. The solution is to physically and electrically disconnect the internal microphone and connect a quality external microphone. Forget the cheap Chinese external mics and source a local lapel electret microphone. The difference will be night and day! Installation is important too - suggest mounting on steering column or (best) pointing back toward driver near rear view mirror (window acts as a parabolic reflector.) Keep away from sides/side window to minimise road noise.

I have read a little about that and it seems that will only fix the outgoing sound(my voice). Will it help the incoming sound that I get from whoever I am talking to on the phone?

This might help the incoming sound if the outgoing is really bad as some outgoing is mixed. The mic mod exponentially improves outbound audio so suggest making the modification and testing your results.

I bought a 7" Carjoying (Android 4.4.4 kitkat; CPU: RK3188 1.6GHz Cortex A9 Quad Core) last january for my 98 ford ranger. While running wires for the GPS, I went ahead and installed the external mic(came with the unit) on my sun visor. People have no issues hearing me, unless I'm on the freeway with the window down. I did not disconnect the head unit mic.

I had the same issues. The audio quality from the one speaker did improve some after updating the software.

i agree, i went from the Joying June update to the mid-August MCU update and I think it does sound better. Still not great, but better

"seicane" aliex - PX3 7.1.2 Bluetooth music A2DP quality poor

Hi guys..
Well first of all how I wish I'd checked these forums first before buying as I wouldn't have, second I wish I'd at least bought from the UK as I'd get some support. But hey ho I didn't and I'm stuck with it as returning to china seems to risky after the message suggested returning at a value of $70 so they don't get taxed and also making sure its sent by EMs so it doesn't get lost in transit like many units do at customs!!
So I bought what seemed to be an all singing all dancing unit from seicane store on ali express, for my seat ibiza mk5. According to the system info via root check app it's a px3, 7.1.2 android, rock chip, rk30sdk.
Amongst many other problems my main one is the Bluetooth audio quality over A2DP is horrendous, and it's not an amp problem as over aux or USB it's perfect. I've been looking at airplay using air bubble app and personal hotspot but it's too long to load and unstable I only drive 15 min to work so just want fast music to my ears! I've considered getting a Bluetooth transmitter and sticking it in the aux input but not ideal.
Anyone got suggestions as to what the issue may be and if it can be resolved?
Thanks in advance hope I can get this stable one day!

mine is also horrendous, and I also have a very short drive. Connecting a hotspot and launching app and getting a song, takes just too long for me. I'm basically already at my destination by the time I get it up. My workaround was to do what you said, and get a bluetooth transmitter and sticking to the aux, because aux sounds fine, but just bluetooth over a2dp sounds so bad, and has this distorted high end sound. This solution worked for me for awhile, but the only downside is you don't get song information on the head unit to display, which is a tad annoying for me.
I've contacted my radios reseller, and they're just ridiculously helpless, all they do is keep sending me a "software" update to fix it, but it does nothing. I've been searching for over a year for a solution, but have found nothing to fix it, other than what I just said. Problem was still there even when I used custom roms. SO I don't really think its a software issue, maybe some kind of hardware I can replace or modify, but I just really have no clue.

Yeh I've ruled out airplay as an option,
you've got me interested though as you're in a similar boat as me so hopefully can help, do you have the exact same unit for an ibiza or?
And yes thats exactly whats annoying me not getting track info, may as well just use the original head unit if i get a bluetooth transmitter!! which transmitter did you get? i've got a really cheap basic one years old and its got a high pitched whining noise in between song skips so its there just muffled out by songs playing, I'm wondering if thats probably just a cheap receiver I've got..
I'll try get somewhere with the hardware see about a new bluetooth module but no idea on the interface would be total guess work and risky at that, not even sure how to safely root this one.
Other issues i'm having which may be common and you may know? I got a dash cam which cam with a yellow RCA, an Acc+ wire, a ground wire and a 12V wire.. i don't understand why its got an Acc+ and a 12V, i thought similar things both transmit power just one off the ignition being on only? theres no 12v out wire on the head unit except 'cam pow' which I've tried to no avail. I plan on recording direct to the SD card on the camera.
Subwoofer out, does this work on our units? i bought it because i plan adding a 4 channel amp for F/R speaks and a sub amp for a single sub.. but does the rca not work / no amplifier control over it?!
Cheers hope to get somewhere with this as i feel a bit down that its not all singing all dancing like i expected lol.

i have a Seicane with Android 6.0 already, which I dont really have any problems with, but it is not PX3
however, I do have a Seicane with Android 7.1 on the way that does have a PX3. I'll report back when i get it to see if I have any issues

Well the 6.0 version is totally different hardware

it is a known issue that no one seems to have a fix for. Im having this same issues with my PX5 Dasaita unit and had this issue on a previous Xtrons unit aswell. I believe it is a problem with the bluetooth drives not supporting the higher bitpools of recent bluetooth updates hence the bad quality. Ive even tried installing a USB bluetooth dongle but could not get the unit to recognize it.

Well I also have a Dasaita PX5 and I definitely didn't have a problem on that one. I would listen to Bluetooth audio on it pretty regularly.
Quick from Hot Audio did email me and ask about it, saying they had heard complaints, and sent me a new harness, but I haven't needed it

Well i've gone an ordered a car play dongle, so hopefully that will be a solution for good radio and a more functional nav at the same time.
Any tips for the dash cam guys? i ordered the 3 cable power one rather than a usb to keep the slots free.. not sure where i should hook them up to. (12V yellow, Acc+ red, black Grnd), i've only got an acc+ on the back of the harness and ground i made an earth wire to the car. Left the 12v off and it doesn't turn on. but my unit doesn't have a 12v, only acc+ or cam pow.

Got a pic or link to the camera you got?

So i have this camera..
https://www.aliexpress.com/item/140...32812106756.html?spm=a2g0s.9042311.0.0.MXwOS4
and this unit..
https://www.aliexpress.com/item/Aft...32827061575.html?spm=a2g0s.9042311.0.0.MXwOS4
The seller said to connect acc+ to acc+ on the unit, 12v to the cars 12v and grnd to the cars ground. I made an earth for the ground just to a screw towards the rear inside of the dash, but not sure where i'll safely take 12v from? especially with the car having a can bus if i splice any wires that may cause an error? Surely these units put out a 12v signal somewhere?
heres the wiring diagrams... https://ae01.alicdn.com/kf/HTB1z7DmnMn.PuJjSZFk763_lpXaZ.png
Also another Q regarding using an external amplifier for speakers and a sub.. is there an issue with the actual volume sent to the amps and can this be resolved? depending what input i give the head unit the volume differs, aux a lot quieter than usb stick or bluetooth.. but even both of them at volume 30 neither are really very loud where you here the speakers distorting, with a standard radio or branded head unit towards top end the speakers would distort so i can set a 'safe' max limit, my concern is the android head unit will limit the amp? and i've seen no info on rooting these units for viper4audio if that would help.
Thanks
Edit: how would i check if the 'cam-pow' wire is putting out 12v with a multimeter? just hold one probe to the wire and touch a ground point with the other?

BT & USB Support on PX5
Guys,
Sorry to tell you, the ROMS are very stripped down and as a result, the only support will be for the listing of BT modules that are on the main board and only for the ones list in the setup. You will not be able to add an external usb BT module to the head unit, it will not reconize them, and therefor will not work. Same with other USB devices. All support has been stripped out of the firmware. Some of these company's are getting slick enough to modify the firmware even more to only support devices that they sell, locking you into buying there junk. Good Luck! I had a BT problem with a Seicane Head Unit, and tried every possible, BT usb module only to find out what they do. Anyone want to purchase BT usb modules cheap!!!!!!

Working Android Head Unit combo with USB DAC

Hi there,
I'm still in my internal debate of doing a tablet car install (like Galaxy Tab S2 8 inch) or getting an Android Headunit to avoid all the install struggles.
So I have been looking around on different forums for quite a while to find a REALLY working combo with an Android Head unit on Android 8.0 and a USB DAC. I would prefer an optical out DAC. Have you any positive experiences and suggestions of both models that would fit ?
I'm planning on getting a Sabre ES9010 based DAC or a Sabre ES9010K2M.
Anyone got it working with an head unit ?
By the way, I'm aware of the issues with the volume with the radio and bluetooth. I will be using a MiniDSP 6x8 with it in a MK5 golf.

i work with joying headunit + with sabre u2 dac.
the volume little loud even when i set it to one. ( i also add more step no change)
for bt call i connect a speaker to the internal amp of headunit, for me its better because my external sound processor add delay to the speakers. ( the speaker work on bt call and radio. )
if u have a physical volume is better, u can try Fain volume control v2 or Precise volume to get the volume more dynamic.

You need an Intel based joying unit. They are still being sold. Works!

Thanks for your answers. So I guess any Sabre DAC world work ! Good news.

I guess I can connect both RCA out from HU to DSP swell as the Optical out. It should be quite easy to switch from one input to another and remove the delay compensation probably.
What specific model are you using from joying ?

The problem is the software on the head unit, the 4gb models are made by a different vendor. The PX 2gb units are made by the same vendor as the Intel, so we know the USB devices work well.

Thank you very much for answering me. So alright, I see. But I guess the Intel units present the same following problems like : 44.1khz/16 bit playback max, no knob volume control and some applications playing only through the HU audio chip?
Because if the 44.1khz/16 bit problem is fixable as well as all of the applications can play though the USB Dac (not mentioning radio or bt audio since I don't care of thoses so much) the Android HU will get interesting...
On another note, do theses head unit run smooth for quite while and will get Android updates? I didn't see any of the Intel based shipped with Android 8.
Still in my internal debate of tablet dash install vs Android HU vs Western brands Android Auto capable stereo...
So again thanks a lot

Firstly I personally don't regard 44khz and 16bit audio as a "problem". It is more than adequate for reproduction in a vehicle with all the other attendant noise sources, especially with a window or sunroof open.
Head unit manufacturers are way way behind other Android tablet and 'phone manufacturers by the order of about 2 years. They are still selling and promoting Kit Kat head units. You probably won't see any Android 8 units for another couple of years, if you are very lucky you may find a Nougat unit to suit your vehicle.
Good hunting, Tony.

Ok then, the Android version does not matters that much. Seems like Android 6 is OK. Thanks.
I have been looking around and found that some people can get the HDMI out from a PX3 7.1 HU to a box that will extract the audio and feed it as optical to a DSP. Is this advisable ? I guess the volume knob will work with it and after all it will be "as good" as a USB DAC out. I understood that the problem are the converters before the RCA out...
On a side note I was thinking about Joying Intel Sofia for vw golf, I have found some Android 6 units, but can't seem to find one with HDMI out. Only Xtrons PX3 seem to have HDMI out for the units made specifically for the vw golf.
So if I understand well, when I'm using a USB DAC, only bluetooth audio and radio will go through the RCA out ? Anything else will go through the DAC ? If using on a Sofia Intel.
I have also been looking at Android Audio to USB, something like the MiniDSP USB Streamer, any thoughts ?
Many many questions again

Hypnox-
I installed a Joying in mine, a VW EOS, and since doing the Heatsink/fan modification, I have been quite satisfied with it's performance. They supply all the looms and can-bus interface to suit your model car and it is the easiest plug and play install imaginable, takes 5 minutes.
I was in the same position as you, although not as fixated on the sound fidelity I was choosing between a tablet and head unit solution. I am VERY glad I chose the head unit, the finished install looks like an OEM unit and performs with very few hiccups. See the piccies of mine below. The unit I chose was a UK-JY-VM130N2D, it has a digital amplifier and 2 MicroSD card slots on the front (I have used them with up to 128gb MicroSD cards) and most importantly for me a physical volume knob.
Cheers Tony.

This is some nice unit there Thank you for your input ! By the way this is exactly the Sofia Intel based unit I have my eyes on. I will certainly make the same mod as you if I pull the trigger on this one and the integration into the dash is very sexy
I'm still trying to figure out the HDMI out audio extraction if possible on PX3 Xtrons unit... I might send Xtrons a mail, but not sure if they will reply. Also trying to know if spotify can use USB dac for audio out... Damn, finding the "somewhat" good unit is not easy task.

Hypnox- You seem to be hypnotised (pun intended) by sound quality. I am a video/ audio engineer with 50 years experience. I have installed hundreds of home theatre hif-fi and casino/night club PA systems.
As we age, our hearing deteriorates rapidly from the age of 12 onwards. In today's world with attendant noise pollution, headphone use, aircraft and motor noise and concert visits, our hearing is far worse than previous generations at an earlier age. Most people over 30 will have difficulty hearing any signal over 12,000khz.
There is a hearing testing app in the google play store, https://play.google.com/store/apps/details?id=mobile.eaudiologia&hl=en using headphone/earbuds why don't you check your own hearing before embarking on a quest for excellent sound in your equipment, you could well save yourself a bundle of dosh and a heap of time!
As we age, the viscocity of the fluid in our ears gets thicker, which is why older people hate the boom boom of bass notes youngsters love so much, it literally resounds inside our heads and is painful. Older folks turn up the treble/high equaliser settings in a vain attempt to hear those high notes we once could hear. This in turn is painful to young people who cannot stand high levels of higher frequencies, because they can actually hear them!
When you try to put a high-fidelity sound system into a car environment, you are basically pushing sh*t uphill. As soon as you open a window, all the careful measurements an audio installer makes literally goes out of the window.
My advice, forget hifi in a car, it's is a nonsense. If you must have hifi in your car, use headphones and let someone else do the driving.
Sorry for the lecture, you don't want to get me started on the monster cable and oxygen-free cable rip-offs
Cheers Tony.

As we age, the viscocity of the fluid in our ears gets thicker, which is why older people hate the boom boom of bass notes youngsters love so much, it literally resounds inside our heads and is painful. Older folks turn up the treble/high equaliser settings in a vain attempt to hear those high notes we once could hear. This in turn is painful to young people who cannot stand high levels of higher frequencies, because they can actually hear them!
When you try to put a high-fidelity sound system into a car environment, you are basically pushing sh*t uphill. As soon as you open a window, all the careful measurements an audio installer makes literally goes out of the window.
My advice, forget hifi in a car, it's is a nonsense. If you must have hifi in your car, use headphones and let someone else do the driving.
Sorry for the lecture, you don't want to get me started on the monster cable and oxygen-free cable rip-offs
Cheers Tony.

I understand your point of view, I certainly don't have the same Audio background as you.
However I'm 28 and a music producer and I can certainly tell the difference between pairs of monitoring speaker. Through the years (still a lot to learn though) I have developed my hear in mixing sessions. And I have a passion for listening to music as well.
I have replaced the stock HU of my car with a 100$ Sony last year and I can tell straight away the difference in sound quality. I also made an audio car install on another car and the difference between the stock system is stunning.
Here, I just want to have a decent audio quality, I know that in car audio there is some serious diminishing return when you build your system.
If you take a look on XDA and like diymobileaudio, you will find hundreds of threads stating that the audio quality is poor even in a car...
You know, If for 50$ I can get a DAC working pretty well with it and that it won't crush the audio quality, I'm all for it

Hypnox- OK at 28 your hearing will be far superior to mine-especially as in my mis-spent youth I was in a rock band before health and safety went bananas, we always used the same stage layout so my right ear is shall we say, less than perfect?
I just hate to see people spending money on a system which as you say is subject to the law of diminishing returns when they could be spending it on other leisure pursuits, or food and housing.....
As long as you get a system that floats your boat and you personally are satisfied, who can gainsay that?
Good luck to you, Tony.

Bump. Would love to get an update on the status of that quest of knowledge.

Please can someone help? I really want (as many of you) to use an external DAC (standard PCM2704) with and android HU. It works with my Android 5.1 Tablet but I am really looking for a compatible HU.
Do you have a model that works with USB DAC? I want a recent one available to buy on market.
Thanks

Lets make this Thread a nice help for everyone
So here is my DAC setup and I can say that the sound is so much better. And with an external eq, it is easy to have access to the Bluetooth and the other things you have inside you Head Units until we find a way to send all the signal to the DAC !!!
First of all,
My head Unit is a: XTRONS TE706PL
To go the DAC way, I brought a preamp CLARION EQS755 and an AudioQuest DRAGONFLY RED
The only problem was that I was getting Pops and bizarre sound out of the signal chain.
I get a AmazonBasics 4-Port USB 2.0 Ultra-Mini Hub and I now connect the DAC and the POPS are almost gone now ( it was a current problem i guess ) Only some bizarre sound comes now and then Flash drive is loading. ( only in DAC MODE )
Upgrade for the future
AUDIOQUEST JITTERBUG will change for the IFI ISILENCER
CHORD MOJO or something in that caliber as an EXTERNAL DAC. ( in about 5 month ) as i need some money
I did a some video to show you the difference in quality and the pops I am talking about
https://drive.google.com/open?id=1LEBDARV6GRV_wF3pInB1fgjwm4Aw8Gbf
UPDATED
Just receive my IFI ISILENCER , I can say that the sound is about 1 to 4 % better with it. I test it in my car and in my house. It kinda makes a difference but you need to really focus to hear it.
I still have that computer distortion coming from both my HEAD UNIT and my main computer. ( this have to be regularize before the current goes to the head unit I guess )
have a good day.
Have a good day everyone !

Did anyone figure out a way to get the android volum control to turn up and down the usb audio output. ??

Dasaita Max 10

I hope I'm posting this in correct section. Has anyone got information on the newest Dasaita Max10-cp? I'm specifically curious about 1280x720 and Android 10
On AliExpress is says it's both 1024x600 and 1280x720 on same advertising page so it's very confusing.
Dasaita communication via messenger is very short answers and they don't seem to answer my questions maybe because there is a major language barrier.
It's supposed to have Android 10.0 among other things. If someone can provide some more info that would be great.

Apparently it's 1024*600 but 1280*720 is coming middle 9r the end of July. This is what I was told by Amazon Dasaita rep.

Hi,
I also bought this PX6 Max10 1280x720.
I found some issues after a few days of use:
1. When no music is playing I can ear a backgroud noise. The seller (Aliexpress MTKNAVI Store) is sending me a new RCA cable, still waiting for it...
2. I have a Toyota Rav4 2017 and with this Max10 all the lock doors settings doen't work such as:
- Lock all doors over 20kms/h
- Unlock when shifting P
- Driver lock button doesn't lock all doors
After speaking with Dasaita over FB Messenger they told that there is a new Canbus version and the seller MTKNAVI is sending me the new one.
So far, all the issues has been addressed by Dasaita and the Seller.
Try to reach Dasaita over Facebook Messenger.

Hi marchnz,
Which one is a known issue, the background noise or the door lock?

He means the background noise.
They released a rca plugs to avoid that noise...normally coming from the stock amplifier....
Customer must specify the version of the car in order to check if the rca is required.

I have just installed one Dasaita Max 10, Android 10, 1280x720.

Get mine in a few days. Will post thoughts here.

Just got mine. RAV4 2014 AWD cruiser with amplifier. I have the same problem with the hissing and background noise does anyone have a picture of the RCA cables that are supposed to fix the issue - it's not these?

I have no idea what these rca cables are that people are talking about, but I doubt they remove hiss. I suspect these people are talking about ground loop noise which CAN be cancelled out with a special rca cable set.... but the hiss is coming directly from the unit itself.
I just ordered a dasaita max 10 and it's still in the mail but my old dasaita px5 is plagued with the same hiss issue which I was never able to get rid of. My guess is that my new max 10 will be the same. Fortunately I drive a jeep with a soft top and big mud tires.... which all pretty much drowns out the hiss
Are you connecting to your amp with the speaker level outs or the rca outs?

I don't think I'm connecting to the amp at all (JBL Greenedge)! I didn't end up using any of the cables numbered 3 to 11 in the attached pic and 14 - 17 are for the reverse camera and factory aux connector. There is no input for it in the bundle of cable harnesses that I can find...am I missing something here?
Thanks for the help, I've asked the seller on Ali about the harnesses - I'll share his replies here.

I Installed mine yesterday and have some issues I bought this one.
C$ 642.79 35%OFF | Dasaita Car Multimedia 10.2" HD Touch Screen Android 10.0 for Toyota Highlander Radio 2015 2016 2017 2018
H5214-MAX10-CP-HD
Hopefully I am just missing something on my setup.
I have a 2018 Toyota Highlander LTD w JBL sound system
I bought the adapter that basically converts the speaker outputs to RCA for the factory amp. I also am using a 4chan Kicker amp so needed to use 4 male to 2 female y splitters to use both. No hiss
My issues are as follows hopefully there is a quick fix.
1. Bluetooth paired with Max10 but just basic info won't send contact info to HU.
2. Offline Nav does not see data without My Samsung Note 9 connected to the MaX10. Using supplied GPS antenna with strong signal.
3. NO Am radio at all ant is plugged in.
Any help would be appreciated. CHEERS

1. Once paired to your Note 9 go to bluetooth settings on your phone and choose the connection to the headunit. You can see a gear . Push it and check the profiles for the connection. Ensure "contact access" is enabled.
In case it doesn't work. Remove the paired connection from both headunit and phone and pair again. I remember the same issue and corrected after deleting and pairing again.
2. Gps offline. Which offline gps did you installed? If you mean igo gps...perhaps maps were not included...note that installed igo is just a pirated copy if the software...so no support
Isuggest you to get a good offline navigator (like "tomtom or "sygic"....or the free "here maps")
3. Check on factory settings that you have setuo the radio correctly to your region (europe, America1, america2, asia...) password for factory settings = 126

Thanks for the help I can go the the gear icon I see phone connection for Calls and Audio but I am pretty sure it should say something more ? The reason I am asking is when on the Dasaita I hit the phone icon I can dial a number but not see any contact info?

I have the same problem - I'll try re pair and see if it fixes things.
"I bought the adapter that basically converts the speaker outputs to RCA for the factory amp. I also am using a 4chan Kicker amp so needed to use 4 male to 2 female y splitters to use both. No hiss"
Do you have pictures or a link to these?

I have IGO nav on my Dasaita px5 and it is most definitely an off line system which does not require a connection. As @ikerg suggested maybe you didn't download the updated maps for your area? If you're talking about google or waze or some nav system like that... they are not really off line systems.
As noted on my above post, I haven't got my max 10 yet (still in the mail. It might come within the next 5 years or so given the speed and accuracy of China Post!) but I did notice with my px5 the request for permission to download bluetooth information (contacts, recents... etc) always came in like 10 or 15 minutes after initial pairing. Never did figure out why the delay, but give it a little while.
Interesting about the lack of hiss. I'm using the rca's directly off the back of my px5 (which I always assumed to be cleaner than the speaker outputs) to my amps and I DO get hiss. Even when volume is ZERO you can faintly hear it. Maybe I will try the speaker outputs

Sorry to be clear I am using the 2v rca outputs as well the y splitters are used for the adapter to the JBL factory amp and to my Kicker amp connected to the outputs from the HU . I guess Dasaita made this adaptor to send a better signal to the factory Amp to get rid of that noise Is my guesstimate Others have said it fixed their issues on the JBL system
And your right probably need to connect through hotspot again and go to maps and download the offline data just like my phone not used to a andriod HU as a stereo replacement.
Anyone know how to get the Max10 to auto pair with my hotspot I leave it on the phone side but have to keep hitting the wifi connection every time .The system setting is set to auto connect i believe.
OK FIXED the Max 10 Bluetooth issue after pairing go to phone icon on Dasaita hit the Sync button two arrows doing the spin third button down on the right menu . Then the request for sharing contact info showed up on the phone request and voila!

Ah ok, so it arrived with your order? I guess I'll need to try and get them to ship the adapter out to me...
Does anyone have a pic of the adapter? I want to see if I could make it myself instead of waiting another month for it to arrive from China

Mine arrived in 5 days with DHL should not take that long. Honestly better to use the head unit power than the JBL but I was feeling lazy LOL
