Hello,
Many thanks for your explanations and recommendations.
Now, I succeed to load the V23 version (from CCD files) and now my screen is back to the original within the GPS function.

My problem is that after rebooting, I inserted the GPS CDROM and as result I got ""NO CD Found in the reader.....""

I went to a BMW store and they said that it is certainly the Calculator which is dead and cost around 1 500 Euros (expensive!!).

I would like if anyone can help me to find out another solution less expensive and much more efficient. May be I need to upgrade to a new version????

Thanks in advance and Regards
