II just bought a 2007 Saturn Aura XR model with factory XM radio mounted the rear package tray. The XM receiver had been damage, so I bought another out of the same car and model and plugged it in. The main radio recognizes it but as the manual indicates it is in theft-lock mode. The local dealer does not know how to unlock it. Is there any answer to unlock other than replace with new XM reciever? The part number on the XM reciever is GM 28043297
