Mein Auto: x3 2005
yes indeed it was at the first post.
so retrofit is same for all X3 from 2004 - 2010...

For the upgrade from Busness to Professional, you will need to go to your BMW Car service to ask for encoding the new setup using the DIS Plus computer.
there are 2 encodings - one that last for 5-7 hous to reprogram all modules in the car (when you add a new device for example - Navigation)
and a simpler encoding through CIP to set the MK4 to high (for prof.) instead of Low (for Business)

for me, the retrofit is not complete yet, as it seems the display is not working - while everything else works just fine ! .... grr.......
I am awaiting for a new lcd screen this week
