Funny you should mention the Amish. A lot of Amish people live near here. Mennonites, too. I doubt they have Navi to get to their outhouses.
A few of you are putting seeds of doubt in my mind re: this issue.
I'd have to ditch the 335xi concept for a 328xi in order to tech-up and learn how to use it. Is that a good trade-off, or foolhardy?
