Delaware just switched to hands free, so I got a motorola hand free device that you clip onto the sun visor. I just like to use it's speaker/mic and don't use the FM transmitter. In my car, I have an 1/8" jack and I like to stream music into the stereo from my Droid X. The problem I have is that it streams the music to the bluetooth device, I only want phone calls to come through, not everything. The same thing happens on my wife's Droid 2. Can you change it where ONLY calls go through the bluetooth?
