Parrot Bluetooth hands free kit MK6000 with mute yellow wire plugged into my audio systems mute wire it seems to mute everything even calls nothing heard through speakers at all. unplugging the mute wire sound works but does not mute when call are received or made. streaming music doesn't change to auxiliary either without the use of the mute wire. Any advice?
