For anyone with poor reception you might want to try adding an amplifier if your car doesnt have one. I live in a pretty bad area for most stations but bought a little booster from Maplin (£7.99) - reception is a lot better and im able to pick up a lot more stations. Very simple to fit. Just a small pen-sized unit that plugs in between your tuner module and the antenna cable, and connects to the tuner's power feed.
