Hello Saul. The 4 screws are only there to block the holes off. You need some radio prongs. These insert into the holes and move a metal release mechanism on the side of the radio. These prongs are very hard to get hold of, but if your local dealer is a good 'un, they might do it for you. Make sure you have your radio code, because you will need it when/if you put the radio back in. Good luck.
