Comand APS
I updated Comand APS of mb E270 CDI 2004 to the newer version which is provided in this website i chose COMAND service update – (W 211 589 13 22 00) for model series 211 section to download the software. the update went well now i have the version 30/2006 (V21.090) i can play mp3 cds.
The problem is now my NAV and MAP button shows only blue screen of TV and does not show map or navigation anymore.

the car belongs to my brother and if he find out this he will kill me

would you please tell me what to do or how to return to the old version which everything was working

guys please help me as soon as possible if you can, Thank you.
