I previously had used my droid with a wired connector into my cars audio input as a car speakerphone. It worked great. People could hear me through the droids microphone and I could hear them through the stereo.
I bought a bluetooth stereo gateway because I wanted to be able to answer calls with my droid in the dock, navigation running in the background.
To my dismay you cant send calls over that bluetooth profile. I say why not, I can send it over 3.5mm stereo jack.
Is there an app or hack that allows me to do this, if not what source could I grab (its not in the dialer, its in the actual call screen) that would allow me to do this.
