Dust, Try ringing the local Seller of your type of vehicle and ask them the Codes for your year model. They must know!! if not get them to do some investigating and find out for you, thats what I am doing with My Local Sooby dealer.
I might try hassling SG2 myself to see if I get any joy, I would like a better list of Protocols and the codes for diferent year models and types. I would like to suggest that they update the Firmware in the next model or just do a FW update anyway to bring it up to speed.
