2.1v3 I have a bluetooth car speaker with FM xmitter. I use if for hands free of course and also stream my tunes to hear through my car stereo. Everything works fine connection wise. I can change music tracks by using phone controls or pressing a button on the phone speaker. When I hit the track advance button on the bluetooth device to change to the next song ..sometimes it will dial a random contact!! LMAO!! Anyone else run across this?
