I just bought a 2002 silhouette premiere. Everything seems to be working except for the wireless headsets for the rear audio system. I've done everything in the manual. They were all in their original packing material so I believe they have never been used. Any ideas?

Try new batteries in the headsets. Is RSA switched on? There will be a headdset icon displayed on the main radio dial. I own the same model and can send you a`scanned copy of the RSA instruction card if you need it.
