I am ordering an Xcal2 and the guy I am ordering it from needs the code number. I thought the white sticker on the unit said 6YX1. He said for some reason that wasn't correct. I am currently out of town for the next few days and I don't have access to my car. Did I look in the right place or are the '06 GT's too new at the moment to have the updated software? Would there be another 4 character code somewhere besides the CPU? What would it start with? Do all 2006 GT's have the same code? My 5 spd '06 has nothing on the passenger side door. Thanks
