Translation:
"good morning to all participants, I am a new member.
I have problems with my navigator Becker worked perfectly, but suddenly I get the writing navigator not installed.
I tried to get new maps, change the backup battery of the navigator but nothing.
Anyone to give me advice?
thank you"

Please use English. This is a English speaking forum!
I you don't speak English, use google translate.
As you see, it works. I don't speak Italian.
