When I ordered my 328i I also ordered the NAV system.
But when I started comparing the different systems I soon noticed that the BMW factory installed system (Philips Carin) is not as technologically advanced as some of the other systems. Some arguments:
Does not have automatic intersection zoom
Really slow processor (takes a long time to recalculate route)
I don't like the way the map is displayed
Did not like the voice
Directions sometimes came way too early (e.g. turn left in 4 miles)
This among other things made my cancel the order for the nav system. When I got the car I installed the Alpine navigation system which works great for me. The position of the display makes it more comfortable to read IMO.
And last but not least it cost me $2000 less than the factory installed system...
Of course that is my personal opinion, I'm sure there are many people who are happy with the factory nav.
