Increase Mic sensitivity???


Recommended Posts

Hello everyone,

 

I've been using the F700BT for a few months now, so far everyone keep telling me that they can't hear me loud and clear... Is there any fix for this in the settings or cna I get a better mic?

 

Any suggestions would be really appreciated.

 

 

Thanks!!!

I posted on this issue a couple of times.

I had the same complaints. I took an old Nokia HFM-8 mic and soldered a 2.5mm jack to it (stereo jack also works, just use the two last pins) and this improved the quality AND volume a lot.

 

The mics that come with the avic simply blow!

 

(fyi, the mic needs to be unpowered / passive)

Here are some suggestions for Motorola GSM, GPRS (not CDMA) phones:

 

1. Go to this URL and read about Sound Gain Table File:

 

http://wiki.howardforums.com/index.php/Gain_Table_File

 

2. Download P2KTools (do some google to find it)

 

3. Read instructions from the above URL (howard forums) and change bluetooth device microphone and speaker gains using P2KTools (to your cell phone your AVIC is the bluetooth device)

 

I have been able to improve my Avic BT700 microphone gain as well as bluettoth speaker gain. DO NOT CHANGE your phone mic gain or phone speaker gain - could be easily damaged if you increase it to much.

The europeon model of this unit posted a firmware update addressing the mic pickup sensitivity issue. The us model didn't get it though, naturally.

 

I have an iphone 3g, and I hear a lot of complaints how people can't hear me and I sound very faint, far away.

 

This wasn't the case prior to 2.0 update, so its definatley software, not hardware mic. Also, just to prove its not the mic, voice recognition works fine.
