loss of power to radio/antennae

Yes, nothing happens at all now when we attempt to turn the radio on. We did check both fuse boxes, specifically the radio fuses, which appeared fine. Thank you for your response.

HELLO , OK ASSUMMING ALL OF THE FUSES ARE GOOD , THEN YOU MAY HAVE TO REMOVE THE RADIO AND CHECK TO SEE IF THE RADIO ITSELF IS GETTING POWER AND A GOOD GROUND ,, A WIRING DIAGRAM WOULD BE HELPFULL , HOWEVER MORE THAN LIKELY THE POWER WIRE ON THE BACK OF THE RADIO WILL BE RED AND THE GROUND WIRE WILL BE BLACK IF YOU DO HAVE A GOOD POWER SOURCE AND A GOOD GROUND THEN MORE THAN LIKELY IT IS SOMETHING INTERNALL WITH THE RADIO ITSELF
