Could someone update me on where this is going about the split screen?
I have a 2004 4.4i sport X5 and test drove a 2008 yesterday. Previously I have gone with a Garmin unit (2720) mainly because the maps have some incredible details but also because the announcements are (usually) accurate and include information I want (which often means a street name). I drive two long trips in places not known to me and so I want to hear instructions and not have to look down at the map itself unless I'm going under 90 mph.
However, while I like the portable unit since it comes in handy with rental cars, I am at a point where I would like a factor unit if BMW has improved their software and maps.
