[s-cars] Blaupunkt MDP-01 Compatibility - NOT COMPATIBLE :-(

[Kirby Smith]

Recalling "Modulation Theory" by Black: Your FM radio sounds like crap
because all stations except classical music stations run at 100%
modulation using compressed dynamics.  Given adequate RF signal
strength, the S/N at the FM demodulator, and thereby dynnamic range of
an FM signal, should be better than you can hear in a moving
automobile.  Second, the frequency response is to 15 kHz, and I doubt
many of us can hear beyond that in a moving car.  Linearity of FM can be
excellent, given sufficient S/N.

In other words, blame your modulator, or blame the FM station's
modulator, but don't blame FM.
