URGENT - Tom Tom European Map Issue

[Calculator]

I have purchased the maps for Italy for my Tom Tom.

I bought a new SD card to upload the map to. However, the TT won't connect to my PC with the blank SD card in. When the original SD card is in, it connects fine. When I replace the SD card, it loses the connection and so I can't add the Italian maps.

I am flying tomorrow so any help/advice would be much appreciated.

Thanks

Thanks for the response.

Purchased from Tom Tom.

When I plug in the TT, with the original SD card in, I am prompted to download the update. When I click to proceed, it says that there is not enough memory. When I remove the SD card and replace it with the new blank card, it loses the connection so I can't seem to add it to the new card.

Any ideas?

The problem is that the computer doesn't seem to recognize the TT when the blank SD card is in so I can't restore the backup to the new card.

I have backed up the data from the original card but I can't get it to connect with the new SD card.

Thanks again.

The original card is not big enough for the Italy maps unfortunately.

The only way I can connect the new SD card to the computer is when it is in the TT. For some reason though it doesn't recognize that there is a blank card in there. I have tried a couple of blank cards so the card doesn't seem the issue.

Going to struggle with my trip unless I can get this working!
