Radio removal

I have been everywhere on the net to figure out how to remove my radio. They all have the same answer. However, when I try to remove the bottom part where all the heating controls go it is supposed to come out as an assembly. Everyone shows the complete assembly removed. My problem is only the bezel comes out and the rest of assembly stays in. I cannot figure how to get it out. There is a bolt behind the ash tray that I removed as everyone has done and still the assembly will not come out. In order to get the radio out this assembly has to come out. This one has got me stumped. No one has an answer as to how to remove it. Every place you go on the internet it shows the whole assembly is part of the bezel and mine is not. I cannot figure what is holding the assembly in and I do not want to force it. The air vents on the top of the radio are removed and the two bolts are removed. But, unless I can get the bottom part out the radio will not come out.
