Hi all, Does anyone own this Samsung car dock and charger for the Sprint version Galaxy S II? Samsung ECS-K1D9BEGSTA Sprint SPH-D710 Vehicle Mount - Car Kit My question is "this dock has a mini usb charging port & an audio out port in the back of the unit. The audio out port works fine for listening to music or voice commands thru the car stereo speakers, but as soon as i get a phone call or make a call, the audio switches to the speakerphone or the ear piece. I've set the dock settings audio output mode on the phone to use external speakers when docked, but still the same problem. Does anyone know of any other settings that may help? Also, if i plug the audio cable directly into the phones head phone jack the other person can be heard through the car stereo speakers, but they cannot hear me. Thank you.
