Cool video mate.
3D perspective mode, to enable this, Perspective mode needs to be enabled in 2 places,
1: The hidden setup menu.
Go to the menu screen select set (or settings) and hold menu button for 10 seconds, when the hidden menu appears scroll down untill the perspective mode option is selectable.
2: In the arrow map pointing menu.
Select GPS-Navigation, then Map, then push right button, select Map Positioning and there select Perspective
Here is a video I made of how to get into the service mode.
YouTube - Secret menu on e46 sat nav
Map downloads are not allowed.
Hope this helps
BTW there are Russian version of the voice and text (in Cyrillic)
