Is it possible to have it when a phone call is made or received that the Samsung Epic will not use the headset? I have my phone plugged into my car stereo with an AUX cable when running Slacker Radio, but prefer to use the bluetooth in my car when receiving phone calls. They can hear me on the bluetooth, but the AUX seems to cancel out being able to hear them. Just didn't want to have to unplug the phone each time I got a call since that kind of defeats the hands free option. The aux cable works also to hear the person if I don't have bluetooth on but I got to turn the radio way up sometimes which when the call is over the radio is blasting.
