Yes, the manual is a worthwhile thing to read.
Just playing around with the different controls (while parked) is also worthwhile since not everything iDrive does was in my 2010 manual.
You can change the display to show direction of travel, map facing north, or perspective map. See page 138 in the manual or select the icon on the left side of the display that changes the map direction.
FYI: an E90 is a sedan. Coupe is an E92. No such thing as an "E90 coupe".
