What I can't find are any screws or anything that would allow me to take things apart.
The trim piece around the radio and ventilation controls just pulls off. Work your fingers or perhaps a wide-blade screwdriver under the trim piece, going carefully around the perimeter, and, with a little tug here and there, it should pop off. You'll have to disconnect a few things to remove it completely, but removing this should allow you to see under the cubby and get in there to install what you want.
