Dummy radio cover for double din screens?

Does anyone here know of a good option for covering up a non removable receiver? Im just looking for a way to make it a less tempting target.

I have seen a couple generic covers that look like crappy radios but am unsure of the fit. I have a kenwood ddx470 and would need to clear the volume knob on the left.

I was thinking about using some kydex plastic with some fake connections coming through to make it look like the face plate is removed, but before i get into that I wanted to see what others have done.

 

I had one of those dummy face plates back in 2002. People who rob cars are well aware of them and they are too generic looking to be stock.
