One potential issue with that is that nearby FM radios (including those 
in passing cars) will hear your RX.  It's a real PITA to be driving 
along listening to NPR or a jazz station and have someone's rock and 
roll crap over-ride it.

A related question though -- will there be an audio output that can 
drive a speaker?  There are a fair number of decent speakers that can 
work quite well in a mobile environment with moderate driving power, 
especially if they are well located for the listener.  I'm thinking 
things like the previously cited Motorola speakers, and also some 
compact "mini-cube" speakers I've found at hamfests. I've seen very nice 
installations using these sorts of speakers in mobile applications -- 
some in a head rest, some clipped to a visor in front of the driver. One 
watt to a speaker like this would work quite well.
