I can answer for I40 and the only way to get a descent Bluetooth is to modify the HU according
to the specific thread in this forum. Both HU's carry the same problem.
Be careful when you order to get the correct screen ie. 1024. They sometimes specify it as optional.
Also verify if you have a factory amplifier. If you have, you need another loom and an analog/SPDIF box.
They are cheap compared to the big guy's, so don't expect miracles. They still work.
I've four units for different cars similar to yours.

Can you point out the thread with the HU modification that improves Bluetooth?
The original Hyundai amplifier only takes spdif as an input? Intresting i dont see other i30 owners which use an android HU mention that.
You are right on the optional 1024 (usually extra 25$).
Iam most intrested not in the bluetooth mobile -> head unit connection but more in getting the audio from the original mic (just above the drivers head) connected to the HU. I feel this way i have less of the aftermarked look (additional mic) and also better audio since the original mic is pretty much in the perfect spot.
I guess i can solder whatever connection the original mic has to my headunit. But there might electrical issues or the mic cable be part of some strange car bus system which will it make hard to figure outand connect.

I don't have a hyundai, but I've put aftermarket units in 2 different cars w/ mics and both had the same problem - they are active mics that have noise cancelling & can't be used w/ these HUs. BUT, you can still easily disconnect the microphone from where it is located and put the aftermarket external mic in its place. My car is a 2014 mazda 6, and my OEM mic was in my overhead where my dome lights are. The panel was held in by 2 screws where the sunglasses drop down. I drop those 2 screws, disconnect the mic from its connector, and pull the mic out (it had some weak adhesive around it, very easy to take out). I then ran my external mic up my a-pillar and mounted it exactly where my factory mic was located. Sound quality is very good, everyone can still hear me okay. and everything looks stock.
Just buy a unit w/o BT issues (avoid MTCB units unless they have fixed this... others seem okay).

Are the units in my original post MTCB units?
What is the reason the active noise canceling microphones can not be used?

I didn't check your links so you'll have to check for yourself. An active mic will need to be powered, so you'll need to know the correct voltage and supply it somehow. I doubt it's 12V that you can use directly from the unit but you never know. Read it with a meter.
I guess theoretically you could make it work in that case.

"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

your bluetooth quality is as good as aux? i wonder if its a software bug..

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!!!!!!

Ownice K1 Initial Review

Here's an initial review for the Ownice K1 (2gb ram/ 16gb Rom android 8 version) and from what I can tell, the first one to appear in English.
Background: This is Ownice's new budget model. No built in 4G support, no DVD slot, 4 core processor, slightly lower internal components (Amplifier, Tuner), TFT screen.
I ordered it on the 11.11 sale for about $200 with DHL shipping and added another 9$ for an external Mic. I ordered the version customized for Ford Mondeo/Galaxy/ S-Max.
Also ordered from other vendors: Ownice TPMS system (has not arrived) , Huawei E8372 4G wingle (arrived shortly after the K1 was installed), and reverse camera that replaces license plate light
Ownice shipped it three days later and it arrived in LA four days after that. From there it was brought to Israel by my kind brother.
Initial Impressions: came well packaged with protective film on the screen. Construction seems good. This is a slim unit and nearly all the connectors are breakouts from proprietary pin-outs on the back.
Installation:
Installation into a 2013-14 S-Max was quite easy as it simply uses the same mounting holes as the OEM unit, and the included connector is wired for the Ford quadlock harness. That said, it included no documentation whatsoever.
1) Connect three rear break-out connections to the back (Quadlock harness, A/V in/out cables, External mic input) and plug the included canbus decoder into the harness
1a) Notice that on harness wiring there is a wire that has a locking connector in the middle that comes disconnected. Assume this is for the reverse camera and connect it
2) Connect quadlock, revers camera RCA. External Mic, GPS antenna, and radio antenna
2a) Notice that they did not include a correct antenna adapter, run to local car audio guy and overpay for an adapter
3) (Spend next six hours wiring in a reverse camera through hatchback (not so easy!)
4) Shove all the wiring behind the unit (plenty of room there) and screw it in, replace trim, voila.
Future items:
5*) 4G wingle arrived a day later so I have only used it with the K1 in hotspot mode, which works fine. I have not gotten around to attaching it directly via USB
6*)TPMS system ordered from DX.com has not arrived yet.
In Use: In the realm of chinese android head units it is no faint praise to say that a unit simply works as one would expect it to, and this unit really does just work 99% as it should. I'll only point out some highlights and a few small disappointments:
+Unit powers on as soon as key is in ignition, stays on after car is shut down until door is opened (just like OEM)
+The reverse camera comes on BEFORE the unit is fully booted (right after the splash screen) so no significant delay there (this was a very pleasant surprise)
+No need to attach extra reverse wiring from reverse camera to car wiring, reverse is already wired via quad-lock
+Steering wheel controls work as they did with OEM unit (but mode button cycles through all inputs, even if they are not installed)
+My existing BAFX bluetooth OBD2 connected fine and works with the included version of torque
+Sound quality with OEM speakers is fine, at least on par with OEM head unit (despite what I've read about ST TDA7388)
+External mic is sensitive enough to work installed in hidden OEM mic location (grill behind map light)
+GPS reception/accuracy is better than my phone's
+Screen splitting works, and is useful
+Push the right knob in and the screen goes blank
-Radio tuner is not as good as the oem unit (I expected this)
-Bluetooth popup to answer calls does not appear for whatsapp calls
-Touchscreen could be a tad more sensitive
-built in media player does not seem to support WMA (thanks to yahoo music (RIP) I have a lot of WMAs) so I mostly use VLC
-No printed manual, onboard manual app does not work, and I can't find any manual online, so it took some futzing and going through the C500 manual to figure a few things out.
That's about it. I don't spend that much time driving these days so haven't gotten around to exploring all the settings and features, but so far I'm quite satisfied.

I appreciate the review; some follow-up questions...
Please tell me if steering wheel controls (up/down track) work on all music apps or just the stock one. Also let me know if you hear any background clicks/pops/noise when WiFi is being accessed. How is the Bluetooth calling quality - can callers hear you ok? Finally can the stock radio and Bluetooth apps be used split screen?
Thanks!
Jeff

1) Steering wheel controls work with all aps.
2) Haven't heard any noises caused by wifi
3) Bluetooth call quality is good, definitely go with the external mic
4) Yes, those apps and most others work in split screen.

Thanks for the answers. One more question, sorry. Does Ok Google work, and/or can you use Google to initiate a call just using voice or microphone button plus voice? Many units "understand" the request to call but fail to be able to put through the call.
Thanks again!

Sorry for the delay in replying.
As far as OK google calls, since the head unit's Bluetooth functionality works as a microphone/speaker, when you run a google now command on the HU, it thinks you want to make a call using the HU, but it has no phone function of it's own, so it cannot place the call. What would be needed is a button on the HU that activates the phone's google now listening. I don't keep my phone in constant listening mode, so not sure how it would work in that situation. Hope that helps.
Here's a few more observations, not entirely good:
1) The steering wheel next and previous track buttons are reversed.
2) There is a problem resuming Bluetooth streaming from my phone. If you push the play button on the HU Bluetooth app after a restart it will freeze and force a reboot.
3) GPS reception is generally excellent with very quick fix, but occasionally for no apparent reason upon startup it will take 5 or so minutes.
4) Even disabling all of automatic time setting, the unit will inexplicably get an hour ahead when booted and then correct a few minutes later.
5) I can't figure out if there is a way to get the Huawei 4G USB router I bought to function as a modem or only as a hotspot.

Hi Doncres,
I've just finished installing my own Ownice K1/G10 unit for my Hyundai Santa Fe.
Installation was a little bit trickier since in order to use the car's original gps antenna, microphone and rear camera I had to cut some wires and change connectors, as well as installing a stepdown DC-DC converter to get the weird 6.5v power required by the original rear camera.
I've been playing a little bit myself with the unit and, given that I'm quite satisfied with it, I would like to know whether you experienced any of the following little annoying problems:
- handsfree call via bluetooth: remote party is always complaining about a small amount of echo
- general audio volume low even at maximum volume (+30), especially for bluetooth phone calls
- the bluetooth active call popup rectangle gets always in the way, even when the rear camera is triggered by the reverse gear, giving some troubles when parking the car and talking to the phone
- Netflix app not working: I had to install an old 2015 version targeting Android 4.4
- parking assistant lines on the rear camera view have wrong perspective angle in comparison to my camera's viewing angle, thus resulting in a projected trapezium rather than a projected rectangle (i.e. the lines are not parallel to actual parking lines); I know I can disable them, however I'd like to change their perspective angle to match the camera
I read somewhere that there are two hidden service menus on Ownice units: the first is accessible via car settings (the "1260" menu) and this works on my unit
The other should be accessible by dialling a specific string in the phone app, however it seems I cannot start the phone app since the K1/G10 comes with no 3G/4G hardware. Any idea on how to enter such menu?
Thanks,
Alberto

Hi, I'm not sure I can really help other than to confirm a few of the the issues.
-Don't think I have an echo issue, but there seems to be a delay until a caller first hears me.
- I get very good volume. I would assume this is an issue of whether the built in amp is a good match for the speakers. Could be an issue with the impedance.
-Yeah, the call button overlay is sometimes annoying, it can block nav screen as well and no way to hide
-I noticed that Netflix was no showing in the app store, but not a big use for me
-the camera I bought has built in guidelines so I disabled them.
-no idea bout the service menu
The only issues that really bother me are:
-the occasional GPS not acquiring satellites, which I now think may be from a defective antenna. I ordered a replacement and we'll see if that helps.
-the fact that if I have an app like stitcher playing, i then get in the car and it stops it when it connects to the BT, but when I go to the BT music app it will either resume fine or if I pres play it will crash the entire device and force a reboot. Mostly I just run streaming apps on the Unit so not much BT streaming anyway.
Also, my TPMS unit finally showed up 2 months after ordering it from DX.com. Looking forward to installing that some time in the next couple of weeks.

Hi.
I am newbie, and i may be wrong in posting the question.
I got 2 din touch Android for Nissan Murano 2018 - model K1, 2 / 16 GB. Ownice 8227L.
On the manufacturer's website, the model has not been supported by software updates for a long time.
Last owner tried to update it with different firmware versions, including those downloaded from this site, and from 4pda. initially did not save the software that was on it from the factory. Now - it has a version of Android installed in which the radio does not work. Everything works, sound files from usb card play, except the radio.
Help me please, where can I get the firmware on it to make the radio work?

Android Head Unit SC9853 - Nissan connections unsure...

SC9853 8-core Intel Airmont with 64GB / 4GB ram... bought it online... supposed to be suitable for my car model, but I'm a bit unsure, and the Chinese seller did not provide much help yet... no instructions nor manual nor wiring diagram...:
my original car: Nissan Teana 250XV from 2010 (model J32, matches the Maxima A35 dashboard/equipment)
So the top LCD display shows the CD number / Radio station / dual Aircon temperature setting.
The backside Radio/CD player:
(deducted the connections from a Google image from Nissan Frontier)
the dark gray is the Antenna radio, the small white should be the Steering controls, the bottom big connector should be for the AC (should not touch), and the remaining plug is the power/speakers wire.
The 2 connections that went into the top LCD display:
I'm assuming the black one goes into the black connector of the Android harness:
I found similar connections on another post, so I deducted:
It came with 2 USB cables, 1 is 4 pin, the other is 6 pin connector... 1st thought they go at bottom in middle, but from the other post it was for MIC-in ?
it should come with instructions and a wiring diagram?!
Can somebody help with explaining what's what?
it seems the harness has a male and female connector, so the female is to connect to the car cable, and the male goes back into the CD/Radio? so the CD player can still function, it's audio should go through an Aux cable?
The antenna cable has not suitable connection, so I suppose I can keep using the stock radio? there's a cut blue wire on the harness labeled Auto ANT, so I could connect this one to the car cable, though would need to figure out how, looks like it has 2 wires (below is for the newer version model L33, but Radio ANT connection looks identical):
Assuming only 1 of the 2 LCD connections need to be used, one of them is black, so I'm assuming this one goes on the black one of the harness...
Sure hope I can sort this out... biggest issue is the head unit seems to be too long to the back, so I have not been able to reinstall, it sticks out... if I install the GPS it sticks out even further, without the GPS this is how far I get....:
the seller claims it can be installed, they did it before with this kind of unit... so shall try again, but to me it looks like I'm hitting the back of the compartment...
Freaking out as have spent 380 USD on it and it took 2 months to deliver (due to Chinese new year / COVID-19)....
Any help much appreciated, thanks a lot in advance!

If the unit has been special been produced for your car, it should be plug´n play.
All connectors are coded. You are not able to misuse any of them.... So what is your problem now???

Well for one besides the unit turning on nothing works: no sound, also the old radio not working, only short beeps when pressing load/eject CD.
To the Head unit I only connected the main power cable, this one also holds the speakers? So should have sound?
Tried setting the steering wheel controls... Also no luck..
Will try to also connect the brown-blue/white cable which has pin count matching bottom left socket below the RCA socket.
Issue may be this Thailand Teana, steering wheel at right side, most units sold for left side...
You mean coded as in wire colors should match? (Only a few cables are labeled, the sockets are not)
Thanks

ok the seller now confirms these are the connections:
the not marked left bottom and right top supposedly have no function...
Only thing left to try is to disconnect the original car stereo plug, so the Android head unit is connected directly to the car cable without the car Radio connected... but that means the original car radio/cd player is not usable...
could also try to use the AUX cable from the Head Unit's RCA connections and connect it to the head jack of the Radio, suppose should get audio then?
will check the wire colors, suppose they should match the harness wire colors? if the unit would actually physically fit my car could correct the socket wiring so it may work for my car?
(I'm assuming a left hand drive car may have different wiring vs. right hand drive car? as nothing works, except for the screen getting power (no sound, no steering wheel control))

That means that the connectors of the cable tree only match to one single hole in the unit.
That has nothing to do with colors of the cables itself. They most probably don´t match.
Just do it, or drive to someone who is able to help you.

yes, you are right, each cable has a different unique fit, not interchangeable, but for the AC cable there are 2 wires it both sockets going to 2 pins, but only one of them matches with the harness connector (so the other wire has no counterpart = dead end due to on different pins), so possible wrong wiring in the harness?
if it's truly plug and play, I should have at least sound, I have no sound... so something's wrong... or does the software need configuration to enable sound?
for the steering wheel controls there's a menu to configure the buttons, but nothing happens, there is however a setting to change the impedance, maybe should try that next.
what about the Canbox?
its purpose is normally for it to act like it would be the car, what's its role here? why is it needed if it's installed in the car? I read online normally it's used to diagnose without the need of the physical car to be present.

The CAN-Box is most necessary part in the set up.
It provides Ignition, power for the amp and the possibility to use the steering wheel buttons.
I would say that you should drive to a car repair shop to get it built in.

Do you have a link for the unit?

Seems seller may not know his own device:
Looks like mine, so the cable I didn't connect could be the CAN input.
Will try later on
Seller wants me to go to a shop where they'll cut out a part of my car to make it fit... Should I? Rather keep everything original....
Says this TS9 always is bigger size for heat disapation...
This is the link where I bought it:

There is too many of these units out there from sellers that don't give enough information with their products. It leaves the end user scratching their head all too often. I purchased a very similar unit to this. Same thing, no support, no instructions, no manual etc etc.
Did you get it to a shop and were they able to sort?

no, I returned it, as I don't want to cut a piece out of my car, and other sellers say it should not be necessary if the correct unit is installed.
The seller thought me to go to the "Extra Settings" menu to select the right car under "Model", after which it updates the MCU accordingly. After this the only thing I got working was the AC temperature control on the screen, had to set the "left / right Peptide" differently to mirror temp setting so Dual setting matches (left and right is apparently the other way around in a left hand side driving car ("peptide" must be a bad translation as that's part of a protein...).
Is the RCA jack to AUX the only way to get sound through the car speakers? (didn't work either, never got sound... I believe the cable was jamming the original CD/Radio, which didn't function with the head unit in between)
glad I got my money back, and recently found a shop here in Bangkok that can sell and install a proper unit, pheww...

No Mic input on Idoing head unit for 2017 Subaru WRX STI

Forgive me if this has been asked / answered before, but I did lots of searching and didn't find it, potentially due to my head unit being known under another name?
The Car and Setup:
* 2017 WRX STI with Harmon Kardon system
* Stock except for the head unit
* Bought the IDoing Head Unit 2015-2021 WRX / STI for Harmon Kardon (from WRXDaily)
* Followed Smeedia and Boost&Shutter video guides to swap out the old head unit and install the new one.
* Ran external mic up the A-pillar
* CAM-BUS decoder is installed
* HU shows as sprd ums512_1h10_natv
* CPU is UIS7862 Octa-Core 2.0 GHz, with 4GB Memory 64GB Storage
* MCU 2021.04.26 15:40:55 PSTAR_53_L6315_G23P48F64_V:1.0
* Android 10, Build number QP1A.190711.020
* I believe this is an FYT unit, more info here: https://forum.xda-developers.com/t/...unisoc-ums512-q-a-mods-tips-firmware.4396339/
Troubleshooting Attempted:
* Triple-checked that the cables were all plugged in correctly across the whole link and had no pinches
* Rebooted the head unit, re-connected the phone
* Ensured that all other functionality works (Android Auto Wired and Wireless, sound, backup camera, etc)
* Tested mic with a variety of apps, both with android auto and the head unit standalone.
* Tested with a variety of methods of activating the mic
* Looked for software option to enable it, didn't find it.
* All work resulted in the mic not appearing to pick up anything
* Went to Factory menu in settings (PW is 3368) and enabled the 'mic' option; no change
So what I'm wondering is if there is a software option needed to enable the mic, or I'm dealing with a hardware issue?
I suppose I could yank the mic out and plug it into another device, but before I do so, if anyone with some experience here could redirect me, what would be very helpful. Thank you in advance, and let me know what additional information you need.
Update: Added what I've learned about the head unit in case anyone else searches this post, and additional troubleshooting attempted.

Test the mic with PC or laptop first, Android may not register mic at all if mulfunctioned.

Thank you! I'll try this out; not looking forward to taking the dash apart again
Update: Haven't yet had a chance to test the mic with another device; poor weather + busy schedule + lack of desire to take dash apart have delayed. I do have a local expert who is checking if he has a 'known good' mic that I can also try

No need to take apart anything just connect switch / end odf a mic to a laptop while in a car (make a joint or if you have usb 4 pin cable ready)

The external mic connects at the back of the head unit
So there is no way to plug it into another device without pulling the dash

Disconnect it from head unit if possible, and test. It must disconnect at the back it is only connected thru jack .

Ok, I've torn up my dash again. thank you to everyone who gave me suggestions on the mic. Here are the results of my testing. Device details again for reference: iDoing FYT unit UIS7862 MCU 2021.04.26 15:40:55 PSTAR_53_L6315_G23P48F64_V:1.0
Validated External Mic by removing the 3.5mm jack and plugging it into the 3.5mm jack on both a microsoft surface tablet and an old Moto Z play
On the moto Z play, the phone was able to register voice via google assistance. The phone is on its last legs and died, so I switched to the surface
On the surface, I made a test call to a friend in discord, changed from the surface internal mic to the iDoing external mic during the call; friend could hear me and noticed the audio change. I also made 2 recordings, one with the iDoing external mic and one with the Surface internal mic. They sounded different but I could hear both
fully disconnected the harness from the back of the iDoing head unit and downloaded a voice recorder app directly to the head unit (phone was not paired)
Recording 1: Internal mic, "back MIC switch" in Factory menu set to "OFF - Front Mic"
Recording 2: internal mic, "back MIC switch in Factory menu set to "ON - back Mic"
firmly plugged in the harness in the correct spot (it was fully seated) and re-connected the external mic
Recording 3: external mic, "back MIC switch" in Factory menu set to "OFF - Front Mic"
Recording 4: external mic, "back MIC switch in Factory menu set to "ON - back Mic"
zero of the recordings picked up any sounds.
So my conclusions are that one, the external mic does work, and 2, either the iDoing head unit doesn't understand mic input, I have failed to enable it properly, or BOTH the harness and the internal mic are dead.
Any advice?

Last resort - use app called LESSER AUDIO SWITCH , download and install from Google Play store , there inside app you can set input and output for speakers and mic

Thank you! I will try that. This HU already has a method of boosting mic gain; did it to the max and no change.
The other idea I'm going to try is a USB mic, since I do have USB inputs

I tried this, and the only option in the app was the internal mic. Still no dice
I am suspecting a VERY strange software issue. Any other ideas?

Please take a photo of each factory settings and post here...

This is the main setting I've been toggling; I'll get a list of the other settings later today

Ok i literally couldn't find another setting that was remotely relevant.
This thing is borked at the software level. Probably gonna return

Why is front mic off ?

That's the setting that I have toggled. On or off makes zero change

hardware problem or internal mic disconnected

yup. I will wait for IDoing to respond

UPDATE:
IDoing finally got back to me. They claim there is a bluetooth bug causing this issue, and gave me 2 files to "update" the driver. They sent me videos of someone plugging in UBS and the update just 'happening'. I doubt it's that simple. Has anyone performed this update, and if so, could they advise me on how to do so properly? Thanks in advance

I think you must import those drivers from factory settings, there is import button.

Thanks! I tried this; successfully updated bluetooth, but no change in the mic. I am not surprised.
