Thread: Streetpilot v2.35 app release (960x540 to 1920x1080) for Android 4.2.2+

The application always installs internally. The Garmin folder with maps, voices, languages... can be created internally or externally.

So you need to use the apk with proper path for your device for your memory of choice. Again, it is a known problem with Kitkat not allowing full access to sdcard if you are not rooted and have not removed the restriction. In that case try path with "Android/data" in it.
