Some 'radios' have two fuses, one for the memory, where the power is always on, & one for the amp, which is only on when the ignition is on. Are the other circuits on the dashboard working, like blower & dash lights? IF some of the other circuits are also NOT working, look for a fuse box under the hood. I think on the Focus, it's on the drivers side wheel well. Look for a blown fuse.
