new SD Card map can not be selected
I have installed the back up from my computer on a new SD card and now when I insert the new SD card in the car after tomtom logo it asks to select the map. There is only one map DE_AT_CH for germany etc. When I select this map, I get the error message this map can not be used on this device. What should I do to fix this issue?
Info: The old SD card is there but it doesn't work properly anymore. When I insert the old SD card, the tomtom tries to load and it fails and the hourglass loading comes again and again without any success. It happened after I updated the old sd card via tomtom home software on may laptop.
