Just took delivery of a Parrot PMK5800. Works and play very well with the Mogul. Works as a normal BT hands free for the car but has a built in FM transmitter. When music is playing and a call is received, automatically pauses the music, lets you answer the call either by the push of a button or by voice command. When the call is finished, music resumes from pause point. Controls on the unit let you pause, fast forward or rewind, or change tracks without looking at your device. Also comes with a cable to input non-BT devices (MP3 players). Very cool! Not yet available in the U.S. - actually got mine from the U.K.
