Guys I have a 2012 Silverado crew cab with the bluetooth set up. The cell phone I have is a Verizon Droid. Problem I am having is the microphone built into the blue tooth is crap. My friends and customers say my voice breaks up all the time. I am wondering if this is highway noise breaking in or what. Buddy of mine has the factory set up on his 150 and has no issues. Anybody else had this problem with their Sierra or Silverado? What did you do?
