Well I'm thinking about just switching out just the mic element for a better one. Does anyone have any good comparisons with just a better mic; no pre amp?

I am not going to attempt such a simple operation here, andhave had most dificulties locating a mic.

the mic is covered wit ha rubber noisedeflector and probably going to shiled it even more if this is the case. I tried covering around with tissue paper but somehow the mic is super sensitive. I even looked at the MPVr that is a better sounding unit, same mic. so I am not dissappointed

the member says a widerdiameter was used, but no test vids are out I even made the preamp and very easy if the correct info provided very simple to not use a circuit board, you can heat shrink and wrap everything to fit inside but the battery. I may just demo this . i fyou can attempt a solder and desolder I like to hear and see some pics for others to do? thanks

I think I will go another route

As the first part of my mods I went ahead and swapped the mic for the radioshack version. As stated before the OP has the (+) and (-) mixed up.

I don't know that it's worth the effort to swap out the mic as the only thing it seems to change is the frequency response...sound is at the same loudness as before.

I'm still planning on adding a switched mono jack so that I can connect an external mic and/or amp for higher quality sound recording. That still seems the best solution rather than hardwiring something to the main board that hangs off the exterior housing of the camera. Plus by using a switched jack you can retain the internal mic and it will automatically be disconnected when you plug in an aux mic.

so true. I am no longer going to attempt. on the Aiptek MPVr it is laid out Mic1 and tells you (+) (-) on the board, guess this boardd oes no thave that or was on the opposite side? As for the oepning i would no t remove ther ibbon cable it can be flipped comtfortably to the side, the speaker board i and looks to be soldered at two points but is a plug and play like the nav button board

What if one connects a microphone like this one instead of the built-in one?

http://www.supercircuits.com/index.a...mp;ProdID=4123

It is a line-out level powered microphone. I wonder what will be the end result if connected instead of the internal Aiptek mic.

I know it will work in the a/v input and I know it has to be powered - that's not the issue - it will be mounted inside a car (and there is plenty of 12V). My question was different.

I am wondering what will happen if I remove the internal A-HD mic and connect this powered mic to the board ... (what will happen if line level audio source is wired the board instead of the built-in one)

It looks like someone has put examples of an the sound from an external mic port attached to the Aiptek A-HD
