Query: Super powerful GPS receiver

Had this device for a few weeks now. Its been extremely robust and helpful. The size is good enough to keep it from blocking your view and big enough to follow directions.I had this kept in my cup holder for while and even then it had full satellite signal.Some minor recommendations for the software are a mute button on the main display and say "turn left" instead of "keep left" which it says most of the time
