So I have to set the clock for Daylight Savings Time twice? Once for Driver 1 and again for Driver 2? That's really taking personalization too far.

Furthermore, my wife and I both attempted to set the clock by pressing on the clock button on the navigation radio display. All that does is show the date. When that failed, we eventually figured out to go to the Config button, but that's two votes for "the interface could be more intuitive."

My $9.99 atomic clock at home sets itself. But the $9.99 clock didn't do very well on the dragstrip, so I guess I have to forgive GM.
