Google Now voice comands don't work if my bluetooth is connected (Motorola Elite Sliver). When I say "Google" the screen says "Initializing" for 15-20 seconds and then says "Can't reach Google at the moment, Retry". In fact all speech to text functions no longer work when my bluetooth is connected. If I turn the bluetooth off, Google Now (and all speech to text functions) works flawlessly and it's pretty amazing. This is a real pain since I use my bluetooth all day, every day.:-\
