AM radio in X-5


I live 180 miles of bad roads north of Minneapolis. I’ve had 20 cars since moving here. I depend on AM for ball games, news etc on my 160 mile trip each day. All cars have been able to pick up Twin City stations except for my newest ride a 2003 BMW X-5. What is discouraging is BMW has a complex antenna system incorporating a signal booster hidden behind a side panel and an “antenna” in the side window glass. BMW says they are all like this when I have confronted them. They will not acknowledge any problem or fix. They said mine has more power than other X-5’s. I am so unhappy if I thought I could sell this ride, I’d trade it for a decent Honda, Mazda etc.with a real radio and antenna. What ere they thinking
