Query: Listen to your IPOD in your car

Finding a free frequency that works is dificult. When travelling, you get all kinds of static and interference. Going from Ipod to radio is a chore laoded with lots of loud static due to having to increase volume to hear your IPOD and then turning it down to keep from blowing your car speakers. The car charger does work OK.
