when i was in australia over the holidays, i drove from sydney to port stephens (2.5-3hr drive), found a good station and had absolutely no static or issues using the fm transmitter

however back here in the states, im having a lil bit more difficulty finding a solid station throughout the city of SF. i think mainly due to living in an area with a mass amount of radio stations with stronger signals. for my 10 min drive to work, im able to stay on one station with "slight" interference hitting once or twice certain parts. otherwise it seems to do better than the belkin i had for my ipod!
