Hi everyone, great forum you have here. Just purchased a 2008 SC with 11k on the odometer, thus the reason to seek out and join this forum. We have had it for four days now, my wife was driving an Escalade so this is kind of new and exciting for her. A couple of issues we have noticed already, the Sirius radio and memory seat function reset yesterday for no reason (kind of scared we already have an electrical problem), the voice command is very cool, but i guess it does not understand Texan (is there any tricks to make it work better), and the big one is she really felt comfortable with on-star on her old car, (is there some sort of aftermarket service out there)? thanks for help, cheers nick
