is it possible to use the SonyEricsson K750i USB cable directly to the Computer(and using the car speakers and mic as handsfree) instead of using Bluetooth like i do now? people calling me are complaining about echo all the time!
in case, how is it done with USB? just uninstall the bluetooth software and run the phoco configurator wizard again??
i would some for someone to tell me how they are using any phone with a car pc, i cant get rid of my echo at all..
some people have suggested skype certified soundcards that reduce echo. others have wired in a switch to manually turn the mic on when they want to talk and off when the other person talks.
you could try something like this. http://www.auzentech.com/site/products/usb.php

i am looking for a solution as well so if you find something that works, please post.
I decided to mount a webcam and I got a bonus! I found that the Logitech UltraVision has echo cancellation and a noise filter that works well with bluetooth and gets rid of all echo and cleans up the audio. You must use the mic that is built into the webcam. I mounted mine permanently in the car and now use it for voice recognition and bluetooth phone.
