v.3.4 1. Put "UTILITY" folder in Primo's root 2. Open UTILITY\utility.ini and check DirContent= for example: \SDMMC\NNG\Content or \Storage Card\Primo\content or ...) 3. Check ExeName= (iGo.exe or Primo.exe or ...) 4. In Content folder create subfolders: map (if your default are TT maps), map_nt (for NT), map_ot (for other maps) and copy to each folder at least 1 map. 5. For change POI together with maps, set: swpoi=1 and create same folder structure as for maps (poi, poi_nt, poi_ot) Similarly can be configured to switching the following folders: BUILDING (swbuilding=1, folders building_tt, building_nt, building_ot), HISTSPEED (swhistspeed=1, folders histspeed_tt, histspeed_nt, histspeed_ot), PHONEME (swphoneme=1, folders phoneme_tt, phoneme_nt, phoneme_ot). 6. For correct map provider determination please place to each map folder one small file (may be empty, only the name is relevant. Examples are in the folder '_copy_to_the_corresponding_map_folder'): !map_tt.txt - for the Tomtom (former Teleatlas) maps !map_nt.txt - for the Navteq maps !map_ot.txt - for other provider's maps In this case the skin will set the provider correctly during program start and prevent displaying wrong provider that can be caused by possible Mapchanger's fault. 7. MapChanger can be accessed from Quick Menu. 8. Enjoy
