Hi, got a pioneer head unit with bluetooth but the parrot microphone is something shocking, people can hardly hear me no matter the position of the mic. Wondering whether the Audi mic would fit into the pioneer head unit and are the any good and if so any cheap places to get them as ebay doesn't seem to have any. Any would you recommend any others. The parrot one is muti directional and that seems to be causing some problems especially evident if I put it in the Audi OEM position. Cheers all.
