I've got a TomTom One v1, I puchased the latest version of the GB & Ireland map today. The map size wouldn't fit on the original SD card so I replaced it with a 1GB card, making sure that all the files from the original was copied over. I know the it works fine because the TomTom works when I switch it on.
When I finally come to download and install the map from TomTom HOME I keep getting the same error message "Internal Server Error". Has anyone had the same problem?
