The lakes I go to are just out of range of most of the radio stations from the city. Without spending over $100 bucks or changing my head unit, what is the best addition to my current head unit that will help me pick up those fuzzy FM radio stations. I'm thinking an external antenna (maybe wire to the tower? :) and I've heard of 'boosters'? Stereo wizards, I need some sound advice. No pun intended.
