I purchased the City Navigator® Europe NT and two cityXplorer maps for online download to my 3790T.
I have installed a 16gb SD card
The cityXplorer maps downloaded and installed correctly.
However, I have tried seven times using three different computers on two different internet connections (Cable and ADSL).
Each time the download failed with the reason "method with the requested number of arguments not found (session may have timed out)"
I am using a LAN connection.
Is there a solution?
