I made my mca file in my computer. Then I transfer it to my Redmi (portable)
I tried to put them in "Android\data\com.mapfactor.navigator\files\navigator\data" DON'T WORK.
I have no settings but think is Definitions (I'm portuguese) and I have gestor de mapas (map manager) and then I have Confugure downloadin un updating maps. Just maps not mca files
