cm5908 radio mounting cage

I’m unsure who’s this mounts exactly, I’ve read that it doesn’t have a mounting cage but how does it stay locked into place?

also, is it an Alan or torx bit that is used for the 2 screws on the side of the radio?

Alan key. When you turn it it expands the frame to hold it in. sent from hell using tapatalk

So it doesn’t need a mounting cage? Any idea what size Alan? I’ve tried everything I have an none wanted to work
