Thanks for the inputs, especially the owner's manual recommendation. I'm an idiot for not cheking there first. Thanks to Mi5 for the opinions, too. I think I'll skip the HUD and go for the premium sound package instead. If it had more info or customability I might have gone for it. The other thing that scares me is windshield replacement. My bad luck has always resulted in at least 1 cracked windshield in each car I've owned, and my wife for some reason always finds a way to follow trucks carrying big loads of pebbles and rocks!
