This product does not work. I have tried using it with multiple different ipods(ipod, nano, mini), and have tried multiple different vehicles(crysler, honda, jeep, nissan, mazda, toyota), and i have tried using it in multiple different locations(mountains, hills, city, suburbs, valley, beach).nothing works. it charges the ipod fine, but will not transmitt an fm signal to a car radio. i have even parked my car outside my bedroom window and tried to pick up the signal with my home stereo system. it does not work.how can they advertise that it does something that it does not?i am very upset with my purchase,.
