PLEASE HELP: Radio removal on 1994 626

Can someone please tell me how to get the radio out of a 626. I am painfully having to watch a friend of mine try to remove his factory stereo so he can install a new radio. I drive a BMW so mine was real easy. Watching him makes my back hurt. He is grunting an groaning and yelling and throwing tools. Not a pretty sight and soon the police are gonna come out here and arrest him for abuse on his Mazda. So please please please help this poor country boy before I have to call a medic for the car.

Personaly I think if he cant get it out then he probably shouldent be installing one.... anyways there is four holes in each corner of the radio.. You basicly have to press a small flat screwdriver in each hole to release it from the holster... Make sure that you buy an adaptor for the speacker wires in the back...
