I bought a Tune Cast II for iPod for my car. I took the iPod on it's first long trip to Charleston, Il (3.5-4 hrs) a few weeks ago and it was cool to use. I had it connected to the car's tape deck. The tape thing would not work in my wife's car so I decided to get the Blekin Tune Cast II. I am still working with it, but once you find a clean frequency (kind of hard in the Chicago area) it works well.
