I have a TT1XL running App 7.131\n\nI just bought a set of Western Europe maps (v6.75) from eBay that was advertised as working with TomTom One, but all I get when I start up after the maps were installed is "No Maps Found", even though the TomTom Home software shows that the maps are installed properly. Are these maps not compatible with the TT1XL?\n\nI had to get an SD card to hold the maps, so I backed up the TT1XL and restored to the SD thru TT Home, then installed the Western Europe maps using TomTom Home.\n\nThe problem is, as I mentioned, when the TT1XL is booted from the SD card, it goes straight to "No Maps Found". I've tried removing the maps and reinstalling. I've also tried copying the "Western_Europe" map folder directly to the SD card and still no luck. \n\nAny help would be greatly appreciated. I leave for Germany in 5 days and really would like to have TomTom with me.
