Yep just sat at the dealership for 3 hours only to find out that you have to have an On Star data plan which is own by you guessed it GM in order for it to work now it will just initiate you and make you think about it every day the next time you go to purchase their highest priced vehicles. I am sure their thought process is anyone that can afford this type of vehicle won't mind paying $20+ more a month just so they don't have to be annoyed every time they drive.
I say we revolt and find someone that respects us and our intelligence.
Have a GREAT day and enjoy your HUD speedometer!
