All you need to do on the E60 is to slide the iDrive controller to the right, push down once, then choose whether you want "perspective", "map facing north", or "map direction of travel".

Whenever I use the NAV system I have the HUD show the arrow/information display and the right side assist window show the map, and then I leave the main screen on either the Entertainment setting or "Route List". That way everything I could possibly need is displayed at the same time.
