I used a series of those for iPod for the first few years, but lived in Los Angeles, so there was a ton of interference, both from radio stations and other devices broadcasting on the same frequency. It created some pretty chaotic drives from time to time...

Yeah the old school ones (or maybe just the cheap ones me and my friends had) had a only few stations they could transmit. Everyone once in a while we'd be able to tune the radio to one of those stations if we were next to a young person at a red to see what they were listening to, if we thought they had the same device. Maybe we'd kill ours to hear theirs if we heard the static...
