I ordered a Solstice on 27 Jun with all the options except the smokers package, but was told I couldn't order OnStar because it wasn't available yet. I recently read somewhere that OnStar will be available sometime this fall. Does anyone know if I can change my order to include OnStar when it becomes available? My dealer told me "probably not" but then he told me I wouldn't be able to get my VOM# until the car was ready for production. Armed with the info I got from Cadillacricket, I went to my dealer and left with my VOM#.
