I did read the whole topics (is is not very big anyway) and I tried version 2.8 but is is not working for me. It does not find the map files and does not show me anything so I can select to make the switch. I have tomtom maps and Here maps in the same map folder located in igo/content/map. The map changer option is shown in the menu of IGO. When I press this option in the menu I get a message "To change the maps on your device must be installed the program Mapchanger.apk.....".

I try to use the mapchanger on post #33 but it does not show me the maps so I can make the switch. Both map files are in the igo/content/map folder and there licenses are in the license folder. I put is the ux folder the externalmap changer.zip and then I install the mapchange aplication (for internal sd). In the igo menu I can see the mapchanger option.
