I can't follow what you are doing. Are you saying the phone will play through the car speakers when you are not on a phone call? I've not been able to do this with Android. In fact, for a while it made me think the map app was dysfunctional because I would tell it stuff (through it's own mic) and it would be trying to talk to me but I couldn't hear it because it was bluetoothed to the car and the car wasn't playing the audio.
