Hi all together and to @modemakias especially big thx,

I tried the igo pal. Basicly it works fine, but with VR iniciate navigation forgets the navigation order after shut down and restart pal.
When I start a navigation via favorites adresses or by manual inserting the adress it do not loose the navigation order after a restart.

pal is placed in internal memory: storage/emulated/0, just like whatapp and so on; only the content is placed on sd and the phone I use is a homtom S99
