That’s only a problem if you’re using one of the aftermarket fm transmitters to play the device through the car radio. Many new cars have a USB jack in the soundsystem that allows direct connection with the player, with no radio signal needed.
Well, I learn something new every day! Since I have a 10-year old car, no wonder I don’t have a USB port, and I don’t see a new car in my future. In fact I don’t see much of a future if something doesn’t happen in November. I’ll just have to sing to myself in the car.
