Hey,

For what it's worth: I have a VW rabbit '07 that came with a standard AUX input that my Droid X plugs into the car via a 1/4 inch cable. When I get a phone call the call plays through my stereo and without any special equipment the phone still hears when I speak. Not sure if the phone is using just the plain microphone or the speaker phone microphone, but the phone sits in the cup holder and the caller can hear my voice clearly. I guess the phone can detect when headphones/aux cables without a microphone channel are plugged in.

Just my experience.
