Pumpkin AA0495B Mic Issues - Android Head-Units

Hello,
I know there are several threads about microphone mods, But i am not sure which version and hardware I have inside my unit.
The manafacturer response from support is that I can "remove the inbuilt mic"
The problem I have is if I use the inernal mic it is average when stationary with engine off, and whilst engine is running it suffers massive interference and is worse with blower motor going and driving.
If i connect an external mic this does not disable the inbuilt mic they appear to be wired in parrallel.
I am confident with electronics so just need pointing in the right direction.

Some pictures of the boards

Has anyone carried out a mic mod on this unit before?
I have desoldered the internal mic from the front panel but still awful quality sound.

check the positioning of the speaker, youve probably got it in wrong. The notch on it should point towards the touchscreen
bro, I didnt see other than speaker phone,
there are 2 speakers there ? I saw only one on the back side.
fyi, I can call, but I must use speakerphone mode, just like conference ...

If you didnt transfer it over to your new facia that would be a very good reason for it not to be working :lol:

My XDA's headphone socket needs soldered

please can anyone help me here
the headphone socket on my xda is a bit mashed with tiny bits of plastic missing from the entry part, i wasnt getting sound from it at all so i stripped it down and by soldering 2 bits of copper back on i managed to get sound form the internal speaker but the headphones would not work, sound was still coming from the internal speaker. so i stripped it down again but this time whatever i did screwed the sound up totally and now i dont get any sound.
Here is a photo of it bare:

There are 6 solder points round the heaphone socket, (which i have marked)can anyone tell me which ones i need to check to even get sound from the internal speaker?
Can I short out some of them , im not to bothered about headphones anymore, i just need to get the speaker working again

optical looking audio plug?

Ok my Mac Mini of all sorts had an Optical out port that almost exactly like the Headphone jack port on my phone, (black dot at the bottom of the headphone jack) So I'm wondering if it's a feature not mentioned but I couldn't find anything in the tear downs of the phone.
I know it seems silly and like a power hog option but was wondering..
picture of the said cable type that would be used.

what would you even plan on doing with that? plugging an audio out from a computer into a phone seems incredibly pointless.
I do agree unless you are a dj and have the nexus one or a 5000 sound system and want perfect clarity.
like I said seems silly but from the looks of the plug it could be one.

Video recording: stereo audio uneven?

I sometimes use my One to record our band rehearsing, and overall the 'HDR' microphones cope surprisingly well with the high sound levels (we're a metal band with a loud drum kit).
However, I've started to notice that the right channel of the stereo recording seems to be consistently louder and, hence, closer to clipping than the left one. You can kind of see it in the screenshot below. I'm fairly certain it's not due to the acoustic conditions in our rehearsal space.

Main suggestion would be to ensure a proper DAC-section for the pre-outs, otherwise the sound will never be on a decent level anyway.
Since there's a DSP onboard, there must be a digital sound source after it, right? One thing I would wish was a good SPDIF digital sound output, either optical or coaxial. In this way, you give the possibility to include this head unit in a more serious sound setup, and to be able to buy a higher quality DAC.
Make it right hand drive compatible!!!
