I just purchased a 2004 745li. As I passed a state trooper his radar gun. Sent off abeeping noise inside my car. Does anyone know if a factory installed radar detector was an option
Did you pass him at the top of the hour? IF set, the car will beep at the top of every hour. How did the beeping sound, did it sound like a warning alarm? You might have bought a car with an aftermarket radar detector installed.
Its probably a stealth valentine install. I did one on a 5 series before. You can see the band or radar type in the dash if they did it right. Look for knob that looks like the radio one, you'll be able to turn it on and off or play with the volume there.
