Just upgraded a stock V26 MK IV (I have a 2006 model X5).
Turned on perspective mode in the secret menu (be sure to scroll all the way down past the bottom - it is on a line by itself)
All three map mode options are available now.
Very cool.

There are no street names in perspective mode, but map landmarks are still there (so is the white line that guides you to your destination. For some reason the ETA doesn't seem to work (shows zeroes) - but maybe I have to drive around more (?)

The gang at X5WORLD rocks!
