I've tried those boosters and haven't found any one to really work as they say. Come to my house and I'll give you one that goes under the dash so you don't even have that stupid button showing. I live in Northern N.J. where the mountain/big hills can distort the stations as well. You just might have to get another stereo that has a better receiver in it. How about satellite radio? Just be careful in the city, the buildings can interfere sometimes.
