Hoppefully you made a Police report, even if it is only over the phone, get an incident number even if they do not make a written report, then check with the pawn shops and when you find the unit let the Police know where it is, do not let the pawn shop operator know that the unit you examined is yours, or that it is a stollen unit, DO NOT ALERT THEM TO THIS AT ALL, they will hide the unit.
Instead call the Police and have them acompany you to claim your property, they have to give you the unit back, they do not want to be charged with accepting stollen property and they may even point the Police to the idiot(s).
Also have the serial number handy so that you can show and prove that indeed it is your unit, as for the power supply, you can purchase them at any Walmart also take pictures of the mounting and the power supply and if you have one of the unit on the console even better.
