I have recently bought a four year Smart FourTwo that has TomTom built in. It runs off an SD card. Both the Smart & TomTom documentation is pretty poor but I finally managed to update the maps & software plus renew the Live Traffic service. However I am concerned that if anything happened to the SD card the system would be totally useless. What can I do to backup the SD card? I’m assuming it’s nit the same as merely cloning the card to a fresh card as TomTom likely don’t want to make it easy to copy their maps etc What happens if the SD card fails? Can I get a replacement from Smart or TomTom? Ideally I would just make my own backup.
