I have both a 1998 and a 1999 Aurora. I just got a new Craftsman garage door opener with MyQ technology. I was told I need to buy an adapter from Homelink to make the new Craftsman shake hands with my old Homelink. Have spent many hours trying, but no luck even with the adapter. Spoke with the folks at Homelink and found there are versions of Homelink. Version 3 and newer work with the adapter. Does anyone know when GM started putting the Version 3 system in the Auroras? One agent at Homelink told me to forget it. It will never work. I don't give up that easily. Any ideas?
