I was in Boston over the weekend and saw a new 530 on a dealer's lot that was set up for navigation. Navigation Pre-wiring or wording to that effect was listed on the window sticker at no cost.

There were two bottons near the I-drive...menu and voice. The car was locked so I couldn't determine the size of the I-drive screen.

 

november and december production cars are pre-wired for nav

they still have the small screen

nav will be an option from jan 04 production and will no longer be pre-wired for it
