I'm curious if a non contoured, simple flat piece of wood with cut outs for the buttons, LED, and the knob and a small beveled rectangle for the display would look like. Something incredibly plain yet classy and unstealable. Perhaps with an option to engrave the car model make in it to make it appear stock. Or perhaps, the option to engrave my name and serial number somewhere on the plate would be a nice touch. Easier to recover. Perhaps engraved right on the front... Actually that wouldn't be a bad idea to make a $25 option to engrave some words of the customer's choice on the front of the Rio original design as well for theft protection or vanity.
