your talking about the radio screws(the ones on the side of the radio that goes into the brackets?). if so, then those should be philips head screws can be removed by 8mm socket(the head is not round). if not, a trick would be to push in while you turn. another trick is to put a socket on the handle of the screwdriver and attach it to a ratchet. then push in and turn. hope this helps cuz its worked for me a few times. make sure your using the right sized screwdriver head too.
