Hi.

Just a wild guess, as I don't know anything about the internal player structures and all, but here is a reason to not communicate the absence of a tuner module:

If I have a tuner in car, but not at home (which is the most likely scenario), I might want the player (that I switched off in car while in tuner mode) to return to tuner mode even after being switched on at home (without tuner module, obviously).

cu,
sven
