Means no, correct? ;-)

Press MENU button, select SET (SETTINGS), then shortly press and hold MENU button again for approx 8 sec - Service menu will appear. Scroll down to the end and one more click down (to the next screen) - you should see Perspective -> switch it ON.

Then go to MENU -> GPS-Navigation -> Map, then press right selector and on the pop-up menu select Map positioning -> Perspective

If you really have v29 or higher everything should work.

Good luck!
