Some of you are confusing FM Modulator with FM Transmitter. An FM Modulator is to keep the sound quality even, and has nothing to do with whether it's a hardwired system or not. FM Transmitter units broadcast the signal to the car stereo wirelessly. The problem with ALL FM Transmitters, no matter how good the rest of the circuitry is, are
1) Finding a clear frequency. Although the best FM Transmitters allow you to pick a frequency from the entire range (cheap ones are limited to a few) and even memorize several for quick switching, it is very difficult in highly-populated areas to find a frequency where there isn't at least some weak signal coming in, which drives you nuts when the FM Transmitter isn't transmitting (i.e. between calls). And if you have a long enough commute, you end up having to switch frequencies as you drive...often the same frequency that was clear one day, or even time of day, won't be clear the next.
2) Weak as the FM transmitter signal is, it is possible for someone in the next car at a stoplight to hear your music...or telephone conversation! if they happen to have their radio set at the same frequency.
I have a Garmin with FM transmitter that allows picking any FM frequency, and so far have not been able to find one that stays clear day-in day-out in my area.

BTW: I believe the term modulator is used because the original device signal is being modulated on an FM frequency and then transmitted to the radio.

Maybe it's not even and FM signal, just UI of FM in PCM?! Not sure.... but basically absolutely NO issues with interfering with other FM stations, and it sounds really good.
