Did you pursue this project?
Did you end up installing USB ports in those two console cutouts? I've just purchased a '17 RDX and noticed the same thing you did. Those cutouts are the perfect location for back seat USB ports. In looking at what's available in the aftermarket, USB modules that simply plug into dash openings, all appear to bel made for Toyota or Mazda. None is the correct size to pop into the Acura opening. I'm hoping you found something that works (without carving up the RDX plugs).
