I have a TomTom one which I wanted to update. I updated it and then it worked again but went out after a minute. I then tried to make a backup which did not work. I put all files in a separate folder and then formatted the drive and started it up as a new device. now i want to set up the device but it doesn't know maps. I am also afraid that I have not saved it because of the size of the backup file 50mb. I also cannot install a map with updates in the tomtom home app. what now? I had a tomtom with an eewige map.
