2005 320 Fiesta Vee - lost horn, nav lights, accessory rocker switch and all guage lights?

Firefly320

Hi, I lost horn, nav lights, accessory rocker swith and all guage lights? Does anyone know if there is a common ground block under the dash?  I'm thinking ground problem, but maybe there is a lost fuse somewhere.  Any help is greatly appreciated.
Thanks.
