Please help I want to install the Western_-_Central_Europe_2GB_855_2892 on a tomtom one with the 8.544 navcore but it always sais that he can not find the map, the Central_Europe_855.2931 and Italia_855_2938 work perfectly! I've searched all the forum for help but didn't find anything (maybe I need glasses), it-s the 3-rd day of try-ing and retrying! Anyone got some idea about this?
