Doc Searls notes that NPR isn't happy with FM modulators:

Citing widespread interference on broadcast frequencies used by its member stations, National Public Radio has asked the Federal Communications Commission to order recalls of millions of FM modulators that drivers use to play satellite radios and iPods through their car stereos.

Doc makes a great case for why none of that matters - head on over there for his reasons. I have to agree with him - the only interference I've ever heard myself was a Disney bus (in Disneyworld) overwhelming my modulator on a frequency with no radio stations at all. Not exactly a catastrophe warranting a recall, IMHO.
