With cooperation with rf711, we have solved crashing (force close) on some device when the power is connected.
You must make sure the path is correct. Use [Only registered and activated users can see links. ]

I recommend you try internal memory first. example: /storage/CEE0-CCDF/Android/data/com.garmin.android.apps.gmobilext/files/Garmin/

Use Total Commander or similar to find your folder .../CEE0-CCDF/... it could be different.

Thanks to all and to Titanic.
