my os2008 n800 is thinking my sony mex-bt2500 bluetooth car radio as only a headset resulting in poor audio quality. Is there a way to tell the n800 that the reciever supports arvcp resulting in the proper connection. the car radio has a built in mic so u can take calls but my n800 is streaming music over that connection instead of avrcp. please help i know its capable of perfoeming this.
