Excuse the dirt but it doesn't look like it, that black bracket was the Bluetooth adapter socket which has to be removed to fit this in.
There are two holes at the front just before the CD holder possibly for this? I personally wanted the holder at the rear of the cubby so drinks don't hit your elbow when resting or changing gear.
is that a CD holder? well i never knew?
anyway, someone was selling a JDM one on here a while back.

it does hook on the front lugs, however, i definitely get your reasoning for locating at the back of the cubby, I'm defnitely interested in one...although i'll have to clear mine out!!
