Narrative:
On a vector to intercept localizer; both FMGC's dropped all data and we lost navigation radios; maps; cabin pressure controller and managed speed. Declared emergency; took vectors to work the problem. First officer emailed dispatch looking for VFR. I manually inserted the ILS into the rmp; got a good ident; depressurized the aircraft; and flew an ILS with selected speed to a normal landing.
