Not really what I wanted,
This review is from: Griffin iTrip Auto FM Transmitter and Charger for iPod - Black (Electronics)
This is supposed to find an unused radio frequency, however I usually end up trying to find a free channel on my radio then try to get the scanner to that frequency, otherwise I get radio channels getting mixed in with my ipod tunes. It drives me mad when I'm constantly having to fiddle with the settings just to get through one song. On the other hand, the times when I can get it to find a free channel, the sound is crisp and clear!
I think there are probably better products out there. If you travel all over the country like I do, you may want to try something different!
