Mine works good too - there's obviously road noise when traveling over a certain speed. Sometimes, people say they can't hear me well and I switch to the phone. As far as I can tell, it doesn't have any correlation to signal strength. Other times, they say i'm crystal clear. I got F1 ceramic tint. I do agree with others that the docking station does little to 'boost' signal strength, if any at all. The only benefit I see is that it charges the the phone while being secured in the cradle.
