I just install another apk, from ORAK post #83, named "Internal memory (storage/emulated/0)". It works ok for now.
With your apk I have two issues.
First four times, when I start StreetPilot, it always ask me to enter language and locale, no matter what I choose.
After fifth start I choose Serbian locale and language and it stop to ask me for locale and language. Totally strange.
Second issue is when I go to "Where to" an click Home, it start to calculate and after 80% SP stops to work. I need to go to app info and click Force Stop, to start it again. This test is perform without GPS, in offline mode.
This is for now. When I find more time I will try some other things.
