Shift Trick: How to make mic work with headsets.

Original post:

Hello everybody. Actually the idea is a bit rubish as you need to open ur own shift and u must know what exacly ur doing. the headset`s stereo jack enters in a small socket, well inside that socket is a small connector for each line (2 sound +1 mic) wich will disconnect the onboard mic and spearkers all u have to do is to solder a small wire between all the 3 points of the mic. Find a service to do it if u dont know how.
Results: the onboard mic will work even if u plugin or not headsets.

EDITED: I opened and spent 20 mins checking each connection on mainboard and results are NEGATIVE. dont try this home. thank you

Wow , major discovery ! congrats to u , but hv u tried it yrself first ? how well does it work pls ? i will only try dismantel my shift if it was proven that it can be done with yr style , but many thks for sharing anyway , cheers bro - jimmunsw

I used to do and repair electronic devices somewhere between 10 and 15 years ago, that jack functions the same way even today, is the cheapest and easier way to trigger and disconnect main speakers and mic when headset is plugged in. its the mini jack socket used everywhere and if i see a photo of mainboard where this jack is connected; on both sides i can tell you exacly wich is pin 1 3 5 paired with 2 4 6 or 7 8 9, and one more for the ground to confirm my version it must be 9+1 pins of this connection on the mainboard.
in the link above u see an example of a standard socket for x3 jack headset while htc socket seems to have x4 headset 1 for mic 2 for stereo + 1 for ground

please see also http://en.wikipedia.org/wiki/TRS_connector , anyone can atach a photo of the htc mainboard with the best zoom possible to the jack socket pins on both sides?

I thought this to be the case thank you for the imput I am willing to give this a go myself and confirm or deny weather it works this friday so check back in with me on saturday

To enable external mike for phone functions
Is there a similar amateur rewiring that would disable the onboard mike and enable an external mike for phone calls on the SnapVue side?

I am afraid that u cant as near the mic u have some small other things near ur external mic like a button to answer calls wich should be detected by a software or a volume control. i need to buy one more htc headset to open it. but at least the onboard mic could work when u plugin headsets that might be very cool inside cars

i will see what i can do as fars as pic i dont really have a good camera

bad news, read first post. thank you

If we would be able to attach a bluetooth to the mainboard ....

what were your full findings?

Results are:
By measuring the ohms on the htc headset i figured out that first 2 pins are the left and right headset and the mic is third right near the ground.
For the analogic swich that i was talking about on 3+1(ground) it means that on motherboard the trs socket shouldve have 6 + 1 pins soldered (a pair of 2 for wich swiches the headset and one more pair for the mic + 1 the ground) while on the shift motherboard i saw only 4+1 wich means that the headsets are the only ones disconnected => mic d/c is digitally swiched.
Ps: I hope im not wrong, last time i did an electronic repair was like 11 years ago

i'm not so sure about this i did some real minor testing with the headset mic only partialy pluged in and my voice through the headset mic was picked up so actualy i belive that the mic is wired to the headset jack but through the left and right speakers but again i am not sure of this wiring

Another ideea
Another idea that i got from someone who still works on fixing phones, soldering etc is that the lastest jumper is a "releu" a small piece of hardware wich disconnects or connects a set of circuits eq: microphone + the stereo line, based on a triger eq: a connector wich exists at the end of the socket jack, and the other pins of the sockets seems to be the sound and the mic from the headsets
someone really needs to do investigations on this, we are just few steps away

I can confirm this! I used the HTC headset and left the last ring of the plug (GND?) outside of the socket and mic was working in Notes! (But the speakers are still enabled -.-)

scheme elettric microphone and speakers

Hello!
I enabled the aux input of my car radio and wire a cable jacks.
the problem is that when I get a call from my htc hd2, the sound is heard from the speakers but does not work the microphone for conversation because the hd2 course off the microphone of the device active because the headset with microphone.
Is there any way to wire the cable jack (4 pins) and attach a microphone to the cable itself? Some might suggest a scheme electricity?
thanks!
:sorry my bad english

In theory it should work as long as you can get the components and wire the cable correctly. whether or not your mouth would be too far from the microphone might be an issue,

Unfortunately, if I connect the phone jack, hd2 excludes the microphon base to activate the headset that is built, then the conversation can not happen, but I feel he did not hear anything

should understand how the microphone is connected to the headphone series

Depending on where your phone is, you could use a regular 3.5 mm male to male extension going from your radio to the phone. I have mine set up like that and the mic on the phone itself is powerful enough to pick up your voice. I ran a 10ft cable(3.5 mm male to male) from the radio,under the instrument panel, up the side of the door in the molding of the windshield to the sunvisor where my phone is clipped to the visor by the clip on the case. It works fine but you have to adjust the volume between your phone and the radio to find the best combination to avoid major feedback so the caller doesn't hear his own voice echoing in the background. I can't post links yet but if you go to youtube and search "iphone handsfree iphone in car setup" you will see how I did my iphone but I now have the same setup with the Hd2.

Microphones for Joying

What microphones are you guys using for the Joying Sofia units?
When I make calls the other party always complains about poor audio quality coming from me so I'd like to improve that - if possible

You may want to do a test just recording with the microphone, just to make sure the microphone is the issue. Also try changing the mic sensitivity settings in the car settings, see if that helps. I was using the external mic that came with my unit for a few weeks with no complaints. It seemed to work better on the lower sensitivity level in the car settings.
I finally ended up using the microphone that was built in my car headliner already. I just connected a 3.5mm plug to the 2 wires going to the old head unit. It seems a bit softer than the joying mic, but much less background noise.

I have purchased 3 different Joying head units and they all work for recording voice with both internal or external microphones and using a voice recording app but none of them work during a Bluetooth call. Any ideas? I'm stumped. Tried windows phone, android phone and then iPhone. Maybe a bad batch that are all missing a connection to the Bluetooth module?

Hi Cabela,
Which unit do you currently have, I am experiencing similar problems and the manufacturer advised me to disconnect the external mic.
Have you found a work around...

Joying Intel Unit - No Bluetooth Audio from phone

Hi. I just received a brand new out the box replacement Headunit from Joying and Im fearing its brand new defective. When I pair my phone to the device and try to make a phone call, the entire call (both inbound and outbound) is completely mute. There's no audio and I cannot hear anything on the call. When I switch the audio source back to my phone even while on the call I can hear everything fine. I checked my bluetooth settings on my cell phone and they all seemed okay. Phone Audio is enabled, likewise Media. I rebooted, unpaired and re-paired both my phone and head unit. Nothing works... I cannot hear what the other party is saying.
Music and videos all work fine, however; I ALSO cannot hear the touch button input when I touch the screen like I could on my older unit. What happened?

Im worried the MCU might be bad.

Please check whether you have connected the external microphone well,you can check this blog:https://www.joyingauto.com/blog/post/how-to-test-and-check-mic-issue-for-joying-android-head-unit/

Hi, the issue isn't the microphone, I am unable to hear any audio from the call itself which means I can't hear who I am talking to. This is different from the issue where no one can hear me. I tried even with the external microphone completely disconnected and got the same results.
One thing noted from that blog is checking the speaker wire, I'm using the same radio harness as I was using on my older defective 6021 motherboard and the one before that. I compared the coloring on the wiring harness and pinouts on the connector and they look exactly the same so I don't believe its a speaker wire issue either. When I play regular my front speakers work fine.

I am noticing that the equilizer seems to think my front right speakers are my front left and it thinks my front left speakers are my front right. The back speakers seem to be configured properly (when I select back audio only plays out the back, when I go front right audio plays out the front left, and vice versa.) I checked the wiring and the front right and properly connected to the front right wires, as are the front left and so forth... I went and redid the entire radio harness (which worked fine for 2 Joying Sofia Intel units before this one.) and it did not help. Also still no bluetooth phone calls. bluetooth AUDIO works fine but when I make a bluetooth phone call, it is COMPLETELY mute on both ends. I can't hear them and they can't hear me, regardless if the mic is connected or not.

Did you select no amp in the car settings?

Yup

I took the car to work today and had two additional people test their phones on the unit but we replicated the same issue. One was an iPhone and the other was an Android. While they can play bluetooth music through the unit, bluetooth phone is still completely mute, even with the external mic connected. We tried with the AMP setting configured to "IN" as well but it made no difference. I am still not getting any audio from my phone to the stereo.
I am certain all the wiring is correct. I am using a METRA adapter to my car stereo which splices into the Joying unit and it has worked fine on all previous Joying units. The Metra Harness follows the same universal stereo wiring code (white and white black / grey and grey black are front speakers) and connects to my car's factory harness. Also in the equilizer settings, although left and right audio is incorrect, front and rear audio is functioning properly. If I select only rear, only rear speakers play and if I select only front.. only front speakers play.

Did you fix it?

Buzz sound help

Hey guys. I have a Joying headunit and recently i was on a call via bluetooth and the other person said they can here buzz sound so I decided to do some test and started voice recording on the headunit and found out that when car parking lights or headlights are on, it records that buzz sound. Lights off and the sound is gone. Anyone would know, why?

Wen you say you were on a call with BT, can you clarify what you mean. You had a bluetooth headset on in your car connected to your HU? Your HU was getting getting phone call how? Also BT? to you phone? Or you mean your HU was BT to your phone but you were using the HU mic? If your sing BT headset that seems odd and more likely an issue with your headset. IF however you mean you were using BT to connect phone to HU(aka handsfree) and you were using the HU mic(or external mic) welcome to the chinese head unit party. The mics and the internal components are poorly shielded from engine and other electronic noise. Only thing you can really do is buy a better external mic and see if it helps.

That's typically from too much power draw in your cars electrical system. Which can also mean you have some poor grounding. It doesn't hurt to start adding ground straps all around the car. Ground battery to chassis, ground block with ground of battery, ground body with block etc. Inside the car behind the head unit, you can ground your ground wire with a T connection to somewhere metal in the dash. That will help with the buzzing sound while your lights are on and functioning.

well if he's talking about sound on a bt headset,that's something very different, but I assume he meant standard hands free.
