Does your center console have an inside part that can be removed from the console body? I don't mean a removable "tray", but the actual compartment itself. If it can be removed (usually screwed into the outer console or to a bracket, and/or snaps in/out of place).
If you can remove the inner console, then you could drill a couple holes in the sides of it and bolt the scanners in using the stock mounting knob threads (you would need to leave the black metal sleeve on the scanners; the inner DIN case has holes on the side, but they are not threaded).
Alternatively, you could make a simple drop-in bracket out out aluminum flat stock (available at hardware stores" home depot" etc). You could mount the scanners to the bracket then simply drop it into the console.
Good Luck
