I have tried that (not on a Mazda). The radio is still there playing whatever and if there is a valid station the now playing song has to be shown on the other useful screen. On I got the system to default to radio off, but that means I can't control my heated seats w=ithout turning the system on - there are several seconds of noise between getting the system on and it responding tol the volumn knob.
