The cornerstone of a successful installation is placing all files in their correct locations. iGO Luna organizes its data in a very specific folder hierarchy. The main folder is typically named iGO_Luna and should be placed in the root directory of your device's internal storage (or on an SD card). The critical subfolder for maps is \iGO_Luna\content\mg\baseline .
iGO Luna is often released in 32-bit (armv7-a) or 64-bit (arm64-v8a) versions. Ensure your APK matches your device's hardware.
