I have been following this thread and haven't seen this, but forgive me if I'm duplicating. I used a cable to connect my droid 3.5 mm headphone jack into the aux jack on my car stereo. The music on the droid played through speakers and sounded great, so I decided to see what happened if I made a call. The caller's voice came through my stereo speakers and, even though I had the phone in the cupholder, they said they could hear me just fine! This rocks way better than my bluetooth!
