RADIO has two circuits - always hot and switched.
Always hot (M10) does not completely remove all power (pulling it should still allow the radio to play when switched circuit is powered to acc or ign - and radio will turn off instantly with key regardless of delay setting - but will not show the display or answer phone etc when the radio is off) - switched (M12) is the one that should fully reset it - may even need BOTH pulled.
Very poor labeling.
