I couldn't agree more. I will never buy a car again without integrated navigation. It is overpriced but it offers a level of usability, convenience, and safety that's so much better than what you get from a smartphone.
Granted, I live in a large, metropolitan area now, having an always-available map is awesome. I may know where I'm going but if there's an accident or traffic, I can reroute myself with a glance at the map where otherwise I'd surely get lost. Or for example, I don't need it to tell me how to get to work, but having the traffic info showing on the screen lets me know if I should exit sooner than later because of sudden backups a mile down the freeway. In both circumstances, my phone can stay in my murse where it belongs.
I'm not saying everyone should have or needs to have integrated navigation, but I think it's short-sighted to tell someone not to get something because it's not right for you when the person asked about seat cover colors. There are legitimate reasons why people choose to have it.
