Hi Jochen,

to your question: Yes if i click on "read" it responses and navoder shows the correct VIN and Emergency Number and so on. So that looks good but anything you do which requires the MK3 to write something ends with an timeout.

I will try to update the nav with the v17 cd, but i don't believe that this will work. Is there no possibility (i heard that i can send it to VDO/Siemens and they will flash or replace the flash??)

Regards
Neo
