Review title: XM Installation Kit Product review: What a huge difference going from using the cassette adapter for my XM radio to the professional installation with the Audiovox XMFM1 Xpress XM Satellite Radio FM Switch Box! With the adapter the sound was very thin and tinny, and there was no bass to speak of whatsoever. With the professional installation, the sound quality for music is very good, almost CD quality. The sound quality for sports and news is also much better with the professional installation, though it's still not as good as the regular FM. All in all, I'd highly recommend making the investment in having your XM installed.
