hello! I have a similar problem with a Blaupunkt New York 835 that I recently installed in my car. I suspect the GPS software ( i.e. iGo Primo) is a cracked version, although I bought the unit from an authorized dealer . I succeded in updating maps by simply copying them to the corresponding folder on the microSD card, but I am not able to install a newer version of iGo. I have read all the discussions here about Blaupunkt and it seems that the folder structure on my "original" card is entirely different form what it should be.( I have a "RTNavi" folder wich is empty, and a "mobilenavigator" folder which contains the actual software). if anybody has any advice or ideas, I would be very grateful.
