Or, what worked for me was I installed all the stations, DLed to iPod, then set it to the station I would be using. Then, I deleted all the iTrip stations and all from my iTunes library and synced, which took the "songs" off the iPod. Finally, the iTrip was set to the frequency I wanted, and since once it is set it won't change until you program a new station into it, the frequency remains the same without the unwanted files on your ipod. Of course, you'd need to put them back on to change stations, but I've never had a problem, even on real trips when the frequency is actually in use in the area by a radio station. Though, of course, I might have just been fortunate.
