From Europe, first of all a good morning. Have been trying to update a older TT One with a larger (8Gb) memory card. However I can't make it work. Installed Navcore 9510 DSA, later after a couple of resets the Benelux map 975.7685, using Fast Activate, wich worked with a .dct file, but.... the card could not be read by the Tommy. I did not get the remark that NO maps were found on first ...
