Does anyone know if it is possible to activate the internal speakerphone of the XDA I-III/SPV etc devices by means of a contact on the connector pins. Bridge some pins and the speakerphone mode gets launched? Thanks,Phil

I'm after an adapter to work with my WinMo device which allows me to connect up my own Mic.
The one that almost fits the bill is this ExtUSB 3-in-1 Adaptor but the problem is with the Mic!
I have my own Mic already wired in and a fair way from where the adapter is going to be located. Ideally, I just need a 3.5mm jack for the Mic to go into, just like the 3.5mm jack for the audio out.
The final result being I have a handsfree solution in the car, connected up through the car stereo speakers and a handsfree mic.
Can anyone see any issues with this setup? Does anyone know where I can obtain such an adapter?
1) I tried that adapter with my Touch PRO and it messed up somehow the audio managment so after plugging it in once - after receiving a call I could speak but the device become totally unresponsive only reset worked until a next call... so I hard reseted device and bought the HTC original one.
2) You might get a ground loop when using audio together with charging. I have had it with different cars, devices (laptops/handhelds). The ground loop will give you loud unwanted digital noise while charging. There are workarounds but might not be easy to reach. Basically you need to get the power from the SAME WIRE as the amplifier does.
I have this exact setup in my car and it does work, no feedback problems. I also have the same problem of microphone placement. I have been unable to find an adaptor or a microphone with a long enough wire to do what I wanted, so I had to modify my microphone placement(put it on the dash as oppossed to my sun visor where I wanted it). Other than that issue, it does work great, sounds great over the stereo(both phone calls and music), and charges up at the same time. If you do find either an adaptor or a stupid mini usb microphone with about a 4 foot wire, let me know.

How about the charging?... Is there any change in the audio when plugging in? Try lowering the vol of device as low as possible and maximize the vol of amp.
not at all. The way I have it set up, it is charging or powered the whole time. Of the 3 inputs on the adaptor, one goes to the aux in on my car stereo, one goes to a car power adaptor I installed under the dash, and the 3rd goes to the microphone. I have bluetooth on, so it works with the gps reciever I have(I have an older model without built in gps) and I programed 1 of the buttons to turn on the gps program. Another button is programed to turn on the audio player(I think it is pocket player), which feeds audio to the car stereo anytime I have the aux button pressed on the car stereo. When a phone call comes in, the song pauses and all I have to do is hit the little green answer button on the phone to use it as a speakerphone. Audio is great. I have all the wires snake into one of those little pockets on the dash so there are not a lot of wires going everywhere. Takes about 5-10 seconds to set it up when I get in the car, and about 3 seconds to disconnect when I leave.
So I use an aux cable for audio in my car. I can make calls through the speakers this way. Sometimes though the Mic doesn't work and sometimes it does. Does anyone know if there is something that specially triggers the Mic to work?

Sounds like a loose cable connection. Normally those 3.5mm jacks have 3 or 4 sections on them to support stereo audio plus a mic. If your cable was plugged in and got yanked to the side, it might break some wires in the cable or bend the plug internally (phone or car). But I'm speculating here...got another cable you can try?
I have a radio Eonon GA5155F (MTCB) with integrated microphone. I wanted to add an external microphone to improve the quality of my voice during calls. I have no problems echoing or of disturbing background noise. I would just make me feel as close and clear, approaching the quality of my voice to that during a normal call with the phone without a hands-free, because sometimes refer me to feel a little bad.
I bought a Kenwood external microphone (KCA-MC 10) and I connected at female placed on the back of the radio, but the microphone is not detected appears. I have done the test of blowing the external microphone during a call, but the receiver could not hear no noise; on the contrary if you blew on the built-in microphone on the front of the car radio bezel, the receiver feels the annoying noise of the breath on the microphone.
I tried 2 different microphones equal, therefore exclude that both are defective.
I would understand if my car radio accept a second external microphone, or my car radio has something wrong.
Or if I'm wrong type of microphone
and above all I would understand if a second microphone functioning, would function as main microphone, or in union at least built-in microphone, so as to increase the quality of my voice and make me feel stronger and clearer.

You must check if chassis connector is mono and your mic is stereo it might be connected wrong to the wrong channel.
I know that the microphone should be mono , since it has only one circle into the jack . But how do I control the radio ?
however, I have only one connector for the microphone on the back .

Try a stereo connector on your mic and test both channels.
I have tried to insert a splitter that I had at home that has the stereo connector , but nothing changes .
but I did not understand how I should " test both channels " I only have a female connector on the back of the stereo

Use a male stereo connector push it in to the female connector unscrew the top. Use clips to test the top and than the middle
track. Ground connected all the time of course.
I just bought a JY 2.73 Double Din unit and have the poor microphone quality issue for phone calls. I've seen threads about rerouting the external microphone wiring to connect to the internal microphone wiring. I understand this is done because the internal and external microphones are thought to interfere with each other.
My question is whether we can leave the external microphone connection as is (maybe add some shielding to it) but just cut the microphone connections between the bluetooth card and the main board. Can anyone say whether this worked for them?
Thanks,
Hish

Desoldering the internal mic worked well in my mtcd (as an option to remove a jumper or component was not an option) and for my mtcb, tracing the mic+ from the display board to the main board I was able to remove a jumper/zero ohm resistor. The latter is desirable as lowest noise option.
Would putting a small piece of tape on the internal mic hole not achieve the same?

No.
Hi,
As reported by many people the internal mic was terrible on my unit for calls. So I had the installer replace it with an external mic. However, my wife still reports that it sounds like "there is an alien on the line". I have attached a picture of the work done by the installers - is there anything else I can do to improve the call quality?
(in the photo, the external mic cord is unplugged but can be seen - it plugs into the 'socket' next to the bluetooth board. I was thinking that the external mic cord is not shielded all the way to the plug, so this may be an issue?)
The other issue I now have is I seem to have lost the ability to use voice on the unit. I can see the original mic wire has been cut, but I had assumed it would plug in to the socket near the bluetooth board anyway, so the external replacement is just moving the mic nearer to my position - if that makes sense
Thanks in advance!
