I think will be OK if you move all your apps (iGO_Israel, iGO_Avic iGO_Basar. .) to internal memory phone, and create one "Addons" file for all this in sdcard...

sdcard\addons\content\map\copy HERE maps
sdcard\addons\content\buildings\copy HERE buildings
sdcard\addons\content\poi\copy HERE poi

to all sys of program copy:
[folders]
has_secondary_root=1
android_secondary_root_path="/storage/CD03-1D11/Addons"
