I have bought a Clio with the in built Carminat Tom Tom. I have tried to update the SD card. I thought I had but then it wouldn't read the map, and therefore not let me use the display at all or any options. I have then tried to fix this, and formatted the SD card as Tom Tom suggested I do. Unfortunately this won't now be recognised to download a map to and I can't use the back up primarily because there isn't a backup. And I can't get any sense out of that bloody chatbot either. Can someone help me with some advice please, or maybe a backup file to begin with?
