Man, I remember those college days, where I would leave class and my $100k car had the wrong time... It would make me so upset I would have to just drive and drive until the sun going down told me that is was nighttime. If wanted the exact time, I would have to wind the manual clock in my car and set it off my watch, or even possibly look at my pager!
Seriously though... Any other things different? Seat settings m1/m2 settings, etc? Did you code? Did your I drive reset? Is you key battery still good to go?
