Considering i always have a co-pilot (the wife) with me, it would be soooo helpful if she could input info into the nav sys, especially when we need a phone number of a restaurant. OnStar is so inefficient. I can pull over, get a phone number and call the restaurant three times over before OnStar even gets the name of the restaurant right. Let me spell it for you... M c D o n a l d s.. just kidding.
