I have the original iTrip that I bought for my original iPod. I wanted to try it with my iPhone 4 in the car since I sold my deck and the stock car stereo does not have AUX or Bluetooth. This is the device I am talking about if someone is unfamiliar. It connects to the iPod via the 3.5mm headphone jack. The new iTrip devices seem to connect to the 30 pin connector. I plug it in but the light doesn't activate and nothing happens on the phone. I tuned to the correct radio station and played a song but I just got static.
